Primare A35.8 Power Amplifier

The Primare A35.8 is an unapologetically serious amplifier, built to handle the most ambitious multi-channel systems without ever breaking a sweat. It doesn’t posture, it performs. With eight bridgeable channels at 150W each, balanced and unbalanced inputs, and an architecture that invites you to reimagine what’s possible in a high-fidelity or home theater setup. There’s elegance in the design, but the power behind it is absolute. Whether you’re bi-amping a two-channel rig or driving a full 13.1 Auro 3D system, the A35.8 brings Scandinavian engineering and calm confidence to the heart of your system.

Key Features

• 8-channel Class D amplification delivering 150W per channel into 8 ohms
• Bridgeable architecture enabling up to 4 x 375W for bi-amped stereo
• XLR and RCA inputs on every channel for full compatibility
• Auto-sense and standby modes for energy-efficient system integration
• Minimal signal path design with isolated amplifier modules
• Status monitoring LEDs and internal protection systems
• Scandinavian chassis design with understated elegance

Engineering and Signal Architecture

The A35.8’s internal layout prioritizes signal purity and thermal stability. Each amp module is seated within custom heat sinks that isolate it from the main power supply, reducing electrical noise and cross-interference. Signal routing is done through uninterrupted ribbon traces threaded through the heat sinks, minimizing signal path length and maximizing integrity. The result is a layout that supports high output without compromising sonic detail or tonal balance.

Massive Power Supply and Isolation Design

The heart of the A35.8 is Primare’s largest power supply to date, built with Active Power Factor Correction (APFC) and soft clipping circuitry. Power is routed via dual cables that deliver evenly to four amplifier modules at a time, ensuring consistent current delivery even during peak dynamic swings. The isolation strategy reduces thermal and electrical contamination across the circuit.

System Configurations

Each output pair can be bridged for high-power mono use. This opens up a range of possible system layouts:

• 5.1 and 7.1 setups powered by a single A35.8
• 5.1.4 or 7.1.4 systems with an additional A35.2 stereo amp
• 9.1.6 Atmos or 13.1 Auro 3D systems powered by two A35.8 units
• Bi-amped stereo configuration with 4x bridged outputs at 375W each

Input and Output Options

Each of the eight channels offers both balanced XLR and unbalanced RCA inputs. Outputs support 150W into 8 ohms, 300W into 4 ohms, and 400W into 2 ohms. In bridged mode, each pair delivers up to 750W into 4 ohms. Additional connectivity includes 12V trigger input/output and an RS232 port for control systems.

Monitoring and Protection Systems

LEDs under the top cover indicate real-time amplifier status. Red LEDs signal clipping on individual amp modules, while an eight-LED array at the front indicates overheating, DC errors, or power supply strain. The A35.8 is engineered to protect itself while providing maximum performance under load.

Scandinavian Build Quality and User Interface

The enclosure reflects Primare’s minimalist Scandinavian design ethos, with a hidden standby button integrated into the center of the front-panel logo. The compact chassis houses meticulous construction and finish, available in black or titanium. Every surface, control, and interface reflects a commitment to quality and balance — not just in sound, but in form.
