{"title":"Tube Hybrid Amplifiers","description":"\u003cp\u003eA tube hybrid amplifier pairs a vacuum-tube input stage with a solid-state or class-D output section, combining the harmonic warmth and texture of valves with the power, damping, and speaker control of transistors. It is the practical way to get tube character with the muscle to drive almost any loudspeaker, in one chassis, and it sidesteps the extra heat, retubing, and lower power that can come with all-tube designs. Both makers build their hybrids around large linear power supplies rather than switching designs, so the tube stage stays quiet and the output stage stays composed.

The core idea is unchanged, a valve preamp stage feeding a MOSFET power stage, but the details have moved on. The input tube changed from the ECC82\/12AU7 to the higher-gain ECC83\/12AX7 twin-triode, carefully matched to the power-stage gain to accentuate the valve character. The MOSFET output complement was doubled, and a revised constant power supply design gives the amplifier an easier, more relaxed quality at higher levels along with more dynamic headroom.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch5 dir=\"ltr\"\u003e\u003cspan\u003eDesign and Build Quality\u003c\/span\u003e\u003c\/h5\u003e\n\u003cp dir=\"ltr\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/nuovo_front_silver.jpg?v=1780744983\" alt=\"Unison Research Unico Nuovo integrated amplifier silver front panel with selector and volume knobs\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThe Nuovo is unusually well made under the lid. The heatsink is shaped to nestle around a large toroidal transformer, and the volume control uses a long rod so the level is adjusted right at the input rather than routing the audio signal from the back of the chassis to the front and back again. Well-considered mechanical earthing eliminates microphony. The fascia is a thick aluminum extrusion with a non-reflective sandcast finish that matches the two knobs, and the power switch sits on the right side panel.

Stereo imaging has real depth, and in the lateral plane the sound stretches without a break between the speakers. The warmth feels like it comes from inside the music rather than being laid on from outside, which is the trap most hybrid amplifiers fall into. What you get is solid-state power delivery leavened by the grace and polish of a good valve design, an authentic taste of the high end at a sensible price. It is not the most powerful amplifier in its class, but it holds its own with most 100-watt designs and mid-efficiency speakers, always with power in hand and no hint of strain.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch5 dir=\"ltr\"\u003e\u003cspan\u003eConnectivity and Versatility\u003c\/span\u003e\u003c\/h5\u003e\n\u003cp dir=\"ltr\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/nuovo_rear_panel.jpg?v=1780744985\" alt=\"Unison Research Unico Nuovo rear panel inputs, phono, sub output and bi-wiring binding posts\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThe rear panel carries five RCA inputs plus a tape loop, and on our units one of those inputs is fitted as the moving-magnet\/moving-coil phono stage, switchable with internal jumpers.

In a stereo amplifier, both channels draw from shared power supply resources, which means a dynamic peak in one channel can momentarily starve the other. When bass drums hit in the left channel, the right channel's string sustain can compress slightly. In a monoblock design, each channel has its own dedicated power supplies, its own transformer reserves, and its own current delivery path. The DragoN Monoblocks take this further by housing three separate linear supplies in each chassis: one for the tube input stage, one for the N-Core output module's power rail, and one for auxiliary circuits. With six total power supplies across the pair, there is zero shared infrastructure between channels.\u003c\/p\u003e\n\n\u003ch5\u003eThe tubeD Hybrid Architecture\u003c\/h5\u003e\n\u003cp\u003eThe DragoN Monoblocks use the same proprietary tubeD circuit found in the \u003ca href=\"\/products\/rogue-audio-dragon-power-amplifier\"\u003eDragoN stereo amplifier\u003c\/a\u003e, with each monoblock containing a matched pair of 12AU7 tubes integrated into the gain structure ahead of the Hypex N-Core output module. The tubes handle voltage amplification and impose their harmonic character on the signal, while the N-Core module delivers the current and damping factor needed to control loudspeaker drivers with precision. Unlike simple tube buffer designs, the tubeD topology makes the tube section a functional part of the amplifier's gain chain, meaning the sonic contribution of the tubes is substantive rather than cosmetic.\u003c\/p\u003e\n\n\u003ch5\u003eDragoN Stereo vs. DragoN Monoblock\u003c\/h5\u003e\n\u003cp\u003eThe \u003ca href=\"\/products\/rogue-audio-dragon-power-amplifier\"\u003eDragoN stereo amplifier\u003c\/a\u003e delivers 300W\/8 ohms and 500W\/4 ohms from a single chassis with three power supplies shared across both channels.

This headroom means the amplifier operates well within its linear range at normal listening levels, staying far from clipping even during the most demanding dynamic passages. Planar magnetic speakers, electrostatic hybrids, power-hungry floorstanders, and speakers with complex impedance curves all benefit from the DragoN's combination of high power, high damping factor, and dedicated mono power delivery.\u003c\/p\u003e\n\n\u003ch5\u003eOptional 12V Trigger\u003c\/h5\u003e\n\u003cp\u003eThe DragoN Monoblocks can be ordered with factory-installed 12V triggers for $419 per pair.

Rogue's tubeD topology takes a different approach: the matched pair of 12AU7 tubes is integrated into the amplifier's gain structure so that the tube section actively participates in shaping the signal that reaches the Hypex N-Core output modules. The tubes handle voltage amplification and contribute their characteristic harmonic texture, while the N-Core modules handle current delivery with a damping factor and slew rate that tube output stages simply cannot match. The result is an amplifier that sounds like a tube amplifier with the grip and control of solid-state.\u003c\/p\u003e\n\n\u003ch5\u003ePower Supply Architecture\u003c\/h5\u003e\n\u003cp\u003eThe DragoN employs three separate linear power supplies, each built around its own toroidal transformer. One supply feeds the tube input stage, while the other two provide independent, isolated power to the left and right channel output modules. This architecture eliminates the crosstalk and power supply modulation that occur when both channels share a single supply. Each supply uses Rogue's standard high-storage linear design rather than the switch-mode supplies typically paired with Class D modules, contributing to the amplifier's noise floor and dynamic performance. Despite the three transformers, the Class D output topology keeps total weight to just 38 pounds.\u003c\/p\u003e\n\n\u003ch5\u003eBalanced and Single-Ended Connectivity\u003c\/h5\u003e\n\u003cp\u003eThe DragoN accepts both balanced (XLR) and single-ended (RCA) connections, with true balanced operation from input to output for maximum noise rejection. This makes the DragoN particularly well-suited to systems with long interconnect runs between preamplifier and power amplifier, or installations where electrical noise from other equipment is a concern. The balanced inputs also provide an ideal match for Rogue's own \u003ca href=\"\/products\/rogue-audio-rp-7-v2-preamplifier\"\u003eRP-7 v2\u003c\/a\u003e and \u003ca href=\"\/products\/rogue-audio-rp-9-v2-preamplifier\"\u003eRP-9 v2\u003c\/a\u003e preamplifiers, both of which offer balanced outputs.\u003c\/p\u003e\n\n\u003ch5\u003eSpeaker Compatibility\u003c\/h5\u003e\n\u003cp\u003eWith 300 watts into 8 ohms doubling to 500 watts into 4 ohms, the DragoN handles speakers that would overwhelm most tube amplifiers. Planar magnetic speakers (Magnepan, Diptyque), power-hungry floorstanders, and speakers with complex impedance curves all benefit from the DragoN's combination of high power and high damping factor. The amplifier's ability to deliver current into low impedance loads makes it a natural match for speakers that dip below 4 ohms in the bass region, where many amplifiers run out of headroom.\u003c\/p\u003e\n\n\u003ch5\u003eOptional 12V Trigger\u003c\/h5\u003e\n\u003cp\u003eThe DragoN can be ordered with a factory-installed 12V trigger for $249. With the trigger modification and a trigger cable in place, power on\/off is controlled exclusively through the trigger input, letting the DragoN switch with the rest of your system from a preamp, processor, or controller.

This circuit was custom-designed for the Pharaoh (not borrowed from the RP preamp line) and uses Mundorf EVO oil coupling capacitors to preserve signal integrity through the critical first gain stage. The tube preamp feeds into a pair of Hypex N-Core NC500 amplifier modules, an upgrade from the UcD400 modules used in the original Pharaoh. The N-Core modules were developed by Bruno Putzeys and represent Hypex's most refined Class D output stage, delivering 250 watts into 8 ohms and 400 watts into 4 ohms with a damping factor exceeding 1,000. A massive high-storage linear power supply with an upgraded toroidal transformer (larger than the original to meet the N-Core's higher B+ voltage requirements) provides the current reserves the amplifier needs.\u003c\/p\u003e\n\n\u003ch5\u003eBuilt-In Phono Stage\u003c\/h5\u003e\n\u003cp\u003eThe Pharaoh II includes a built-in phono preamplifier that accommodates both moving magnet and moving coil cartridges. Two gain settings (40dB for MM and 60dB for MC) are selectable internally, and loading is adjustable via DIP switches on the circuit board, with custom loading values available from the factory. The phono inputs have dedicated RCA connectors with a separate ground post on the rear panel.

Outputs include five-way gold-plated speaker binding posts, one pair of variable RCA outputs (tube-driven, for connecting a subwoofer or external amplifier), and one pair of fixed RCA outputs. A home theater bypass allows the Pharaoh II to serve as the power amplifier in a surround system by passing the processor's signal directly to the power stage at unity gain. A separate processor loop provides send\/return jacks for external signal processing. The front panel includes a balance control for fine-tuning the stereo image, and the included metal remote handles volume and mute.\u003c\/p\u003e\n\n\u003ch5\u003eWhat Changed from the Original Pharaoh\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNew Amplifier Modules:\u003c\/strong\u003e Hypex N-Core NC500 replaces the UcD400, delivering more power and lower distortion with a larger toroidal transformer to support the N-Core's higher voltage requirements\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRedesigned Phono Stage:\u003c\/strong\u003e Improved MM\/MC section with adjustable loading via DIP switches and custom loading values available from the factory\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNew Headphone Amplifier:\u003c\/strong\u003e Completely redesigned circuit based on the RH-5, using tube drive with MOSFET buffers instead of the previous op-amp design\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCircuit Improvements:\u003c\/strong\u003e Redesigned circuitry using modern CAD systems, improved grounding layout, and refined tube design parameters throughout the preamplifier section\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent Upgrades:\u003c\/strong\u003e Mundorf EVO oil coupling capacitors, upgraded resistors and capacitors in critical circuit positions\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003e\"Dark\" Version\u003c\/h5\u003e\n\u003cp\u003eThe Dark edition builds on the standard Pharaoh II with component upgrades throughout the signal path:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncreased power supply storage:\u003c\/strong\u003e Larger capacitors for improved dynamics and headroom\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUpgraded coupling capacitors:\u003c\/strong\u003e Premium coupling caps for greater detail and resolution\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNaked Vishay resistors:\u003c\/strong\u003e Ultra-precision resistors in key circuit locations\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUpgraded phono stage components:\u003c\/strong\u003e Premium resistors and capacitors in the phono section\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCardas rhodium-plated binding posts:\u003c\/strong\u003e High-quality connectors from Cardas Audio\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJJ Gold Pin 12AU7 tubes:\u003c\/strong\u003e Premium matched tubes with lower noise and tighter tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eExplore the Full Rogue Audio Integrated Amplifier Lineup\u003c\/h5\u003e\n\u003cp\u003eThe Pharaoh II is the hybrid flagship of Rogue Audio's integrated amplifier range.

A pair of matched 12AU7 tubes handles all voltage amplification in the preamp stage, preserving the harmonic texture that makes tube preamplifiers desirable. The tube preamp feeds into a pair of Hypex UHD amplifier modules, MOSFET-based Class D output devices that deliver 100 watts per channel into 8 ohms with a damping factor exceeding 1,000. A custom 375VA toroidal transformer and a massive high-storage linear power supply with multiple regulated stages provide clean, stable power throughout the circuit. The heavy 2-ounce copper circuit board uses precision components and short signal paths to keep the noise floor low.\u003c\/p\u003e\n\n\u003ch5\u003eBuilt-In Phono Stage\u003c\/h5\u003e\n\u003cp\u003eThe Sphinx v3's phono section is a scaled-down version of Rogue's standalone Triton II phono preamplifier design. It accommodates both moving magnet and moving coil cartridges with user-adjustable gain settings of 44dB and 60dB, selectable via internal switches. This means you can run most cartridges without needing a separate phono preamp.

The headphone output is on the front panel via a standard 1\/4\" jack.

Multiple regulated power supply stages isolate the critical preamp and amplifier sections from each other, reducing noise coupling between stages. The result is deep energy reserves for bass passages and dynamic peaks, combined with a quiet, black background through the midrange and treble.

The first stage uses a pair of Gold Lion ECC83\/12AX7 valves operating in pure Class A, establishing the sonic signature with exceptional signal purity, extremely low distortion, and remarkably quiet operation. The subsequent solid-state stages operate in perfect synergy with the valve section, adding current drive and output capability without compromising the tube stage's musicality. This hybrid approach captures the harmonic richness of tubes in the critical voltage gain stage while relying on solid-state devices for the current delivery and low output impedance needed to drive long cables and complex loads.\u003c\/p\u003e\n\u003cp style=\"text-align: center; margin: 20px 0;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/pre_v2_side_panel_landscape.jpg?v=1771271719\" alt=\"Unico Pre V2 side panel showing three ventilation sections with internal components visible through the grilles\" style=\"display: block; margin-left: auto; margin-right: auto; max-width: 100%;\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\n\u003ch5\u003eBuilt-In ESS Sabre DAC\u003c\/h5\u003e\n\u003cp\u003eA fully integrated digital section centers on the ESS Sabre ES9018K2M converter implemented in a dual-mono balanced output architecture that feeds directly into the preamplifier's analog signal path. Unison Research designed the DAC board with the same dual-mono philosophy as the rest of the preamplifier, and the result is a built-in DAC that performs well above what most buyers expect from an integrated section. The USB input handles PCM signals up to 384 kHz and native DSD up to 256x (with DoP support up to 128x), making the Pre V2 compatible with virtually any high-resolution digital source. On Windows 10 and newer, the USB input is completely driverless, working natively without any software installation, the same plug-and-play experience Mac users have always had. Two Toslink and two S\/PDIF coaxial inputs support signals up to 192 kHz, providing connection points for CD transports, streaming devices, and televisions without requiring a separate DAC component.\u003c\/p\u003e\n\n\u003ch5\u003eMM\/MC Phono Stage with Passive RIAA\u003c\/h5\u003e\n\u003cp\u003eThe built-in phono stage uses passive RIAA equalization with high-precision components in a dual-mono configuration for accurate, low-noise vinyl playback. This is a meaningful upgrade from previous Unico preamplifiers, where the phono section was less refined. Rear-panel DIP switches allow independent load and gain adjustment for both left and right channels, accommodating everything from high-output moving magnet cartridges to low-output moving coils. This dedicated phono input means the Pre V2 can serve as the center of a vinyl-focused system without an external phono preamplifier.\u003c\/p\u003e\n\n\u003ch5\u003eR2R Resistor Ladder Volume Control\u003c\/h5\u003e\n\u003cp\u003eRather than a traditional potentiometer, the Unico Pre V2 uses an integrated circuit based on an R2R resistor ladder network. This design eliminates the channel imbalance that plagues conventional pots at low volume settings and provides extremely accurate, repeatable attenuation steps across the entire range. The result is a volume control that tracks perfectly between channels from the first click to full output, preserving spatial imaging and tonal balance regardless of listening level. The infrared volume control system also enables seamless remote operation.\u003c\/p\u003e\n\n\u003ch5\u003eA Complete System Starting Point\u003c\/h5\u003e\n\u003cp\u003eThe Pre V2's built-in DAC and phono stage make it possible to build a high-performance separates system with fewer boxes.

The phono stage handles your turntable, the DAC handles your streamer or computer, and six analog line inputs accommodate everything else. As your system evolves, the Pre V2 accommodates upgrades: add a dedicated phono preamplifier or external DAC whenever you're ready, and the Pre V2 simply becomes the switching hub and gain stage that ties it all together.\u003c\/p\u003e\n\n\u003ch5\u003eUnico Pre V2 Connectivity and System Integration\u003c\/h5\u003e\n\u003cp\u003eThe Pre V2's rear panel reflects its role as a system command center. Three RCA and three XLR balanced line inputs handle any combination of analog sources, while the phono input adds a dedicated analog connection point. The five digital inputs (USB-B, 2 Toslink, 2 S\/PDIF) cover everything from computer audio to streaming devices to disc transports like the \u003ca href=\"\/products\/unison-research-unico-cd-due-cd-player\"\u003eUnico CD Due\u003c\/a\u003e. Output options include two RCA pairs (up to 8V), one XLR balanced output (up to 16V), a dedicated line output, and dual subwoofer outputs for systems with powered bass. Those output voltages are significantly higher than most preamplifiers on the market, ensuring the Pre V2 has no trouble driving any power amplifier to its full rated output, even over long cable runs. The 12V trigger output enables synchronized power-on with a companion power amplifier.\u003c\/p\u003e\n\u003cp style=\"text-align: center; margin: 20px 0;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/pre_v2_rear_panel_landscape.jpg?v=1771271721\" alt=\"Unico Pre V2 rear panel with phono DIP switches, RCA and XLR inputs, digital connections, dual subwoofer outputs, and 12V trigger\" style=\"display: block; margin-left: auto; margin-right: auto; max-width: 100%;\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\n\u003ch5\u003eItalian Design and Build Quality\u003c\/h5\u003e\n\u003cp\u003eHandcrafted in Dosson di Casier, Italy, by A.R.I.A. srl, the Unico Pre V2 introduces a completely renewed design language for the Unico product family.

This significantly reduced crossover distortion compared to standard Class AB, but didn't eliminate it entirely. Twenty-seven years later, the engineering team revisited the problem from the ground up.\u003c\/p\u003e\n\u003cp\u003eA.S.H.A. (Analog Synchronized Hybrid Amplification) takes a fundamentally different approach. Instead of two output transistors trading control of the signal back and forth (the source of crossover distortion in every Class AB amplifier), A.S.H.A. designates one MOSFET as the \"Leader\" and the other as the \"Follower.\" The Leader MOSFET operates in pure Class A and maintains control of the output signal for the entire waveform period, both positive and negative. It never hands off. The Follower MOSFET, biased in Class AB, handles the heavy current delivery during the negative half-cycle while the Leader continues steering the voltage.\u003c\/p\u003e\n\u003cp\u003eThis synchronized relationship is the key. Because the Leader never relinquishes control of the signal, there is no handoff between transistors, which means there is no crossover distortion. Period. The circuit achieves the signal purity of a pure Class A amplifier with the thermal efficiency and power output of Class AB. Power dissipation stays comparable to conventional Class AB designs, so the DM V2 runs warm but doesn't require the massive heatsinking or ventilation that pure Class A amplifiers demand.\u003c\/p\u003e\n\u003cp style=\"text-align: center; margin: 20px 0;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/dm_v2_top_down_landscape.jpg?v=1771271723\" alt=\"Unico DM V2 side panel showing dual-mono ventilation layout with diamond center grille and internal circuitry visible\" style=\"display: block; margin-left: auto; margin-right: auto; max-width: 100%;\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\n\u003ch5\u003eWhat Zero Crossover Distortion Sounds Like\u003c\/h5\u003e\n\u003cp\u003eThe practical consequence of A.S.H.A. shows up in two places most conventional amplifiers struggle. At low volume, where Class AB designs typically lose bass definition and detail as the output transistors hover near their switching threshold, the DM V2 maintains full frequency response. Bass stays present and defined even at background listening levels because the Leader MOSFET is always conducting, always in control. At high volume, where crossover artifacts in conventional amplifiers accumulate and mask fine detail, the DM V2's output remains linear. Musical detail that usually disappears as you push the volume stays vivid and resolved. The amplifier's distortion profile doesn't shift with power level, and that linearity is something you hear immediately: there's no strain, no hardening, no point where the sound starts to compress.\u003c\/p\u003e\n\n\u003ch5\u003eDual-Mono Power Supply\u003c\/h5\u003e\n\u003cp\u003eEach channel of the DM V2 is fed by its own dedicated 750 VA toroidal transformer, encapsulated, potted, and shielded to minimize electromagnetic interference between the power supply and the sensitive audio circuits. This true dual-mono architecture means the two channels share nothing except the chassis and the mains cable. When switched to bridged mono operation, the two power supplies work in parallel, creating a combined energy reserve that supports sustained output of 650 watts into 8 ohms and 650 watts into 4 ohms.\u003c\/p\u003e\n\n\u003ch5\u003eThree-Stage Amplification\u003c\/h5\u003e\n\u003cp\u003eThe DM V2's signal path is organized into three distinct stages. The input stage is a pure Class A circuit using two Gold Lion ECC82\/12AU7 dual-triode valves, responsible for the speed, fine detail, and natural harmonic structure that set the amplifier's sonic signature. Even in a dedicated power amplifier, this tube input stage matters because the preamplifier signal still needs amplification before reaching the output devices. Unison Research uses valves here deliberately: the solid linearity and warmth they bring to the critical first gain stage carries through the entire signal chain. The second stage is a solid-state adapter circuit that conditions the signal for the output MOSFETs. The output stage uses three complementary MOSFET pairs per channel in the A.S.H.A. configuration, chosen for their tube-like transfer characteristics and ability to deliver high current into low-impedance loads.\u003c\/p\u003e\n\n\u003ch5\u003eStereo and Bridged Mono Operation\u003c\/h5\u003e\n\u003cp\u003eA rear-panel toggle switch allows the DM V2 to operate in stereo mode (220W\/8Ω, 340W\/4Ω, 370W\/2Ω) or bridged mono mode (650W\/8Ω, 650W\/4Ω). In stereo, the amplifier's two channels drive a pair of speakers from a single chassis. In mono, both channels combine to drive a single speaker with dramatically increased power and current capability. A pair of DM V2 amplifiers in mono configuration creates a system capable of controlling the most demanding loudspeakers, including large planars like the \u003ca href=\"\/products\/magnepan-lrs-floorstanding-loudspeakers-pair\"\u003eMagnepan LRS+\u003c\/a\u003e and power-hungry floorstanding designs.\u003c\/p\u003e\n\n\u003ch5\u003eUnico DM V2 Connectivity and Speaker Integration\u003c\/h5\u003e\n\u003cp\u003eThe DM V2 accepts signals through both balanced XLR and unbalanced RCA inputs, making it compatible with any preamplifier.
