Primare A35.8 Eight Channel Home Cinema Amplifier

A35.8 eight channel fully bridgeable amplifier 

Not only is the A35.8 is the most powerful amplifier Primare has built, but it is also the most flexible, designed to serve the needs of virtually any high-performance two and multi-channel system through its ability for each pair of its eight channels to be bridged to mono for an incredible level of power delivery, up to 1500 watts in total. 

Status Indicator System 

At start up, eight internal red LED lamps, one at the base of each amp module, will flash should clipping conditions occur, visible through the top cover from above.  

Additionally, an eight LED warning system is located under the top cover at the front of the amp that will indicate the following: 

• On – DC is detected on the related amp module 

• Flashing – overheating on the related amp module 

• All lights cycling – power supply unit overheating 

Power Supply 

The foundation of the A35.8 is the largest power supply Primare has ever designed, incorporating APFC and soft clipping circuitry, implemented to ensure stable performance up to the very limits of its capabilities. Dual connecting cables from the power supply mean that each group of four amplifier modules are provided with more direct and consistent power delivery by the shortest power path. 

Amplification Stage 

The ingenious design of the A35.8 circuit layout provides the most direct delivery and even distribution of power from the power supply to the amp modules tucked into heatsinks that isolate them from any power supply noise. In turn, this innovative construction isolates the input and output stage from any noise the amp modules might produce. Input and output signals are delivered to and from the amp module through an uninterrupted ribbon of circuit board threaded through a channel in the heat sinks for the shortest possible signal path. 

Inputs/Outputs 

RCA and XLR balanced input options are offered for each of the eight channels and bridging capabilities for each pair of channels, with maximum power output of 1500 watts, providing the capability of delivering 185 watts at 1KHz of peak power per channel, all channels driven.  

• Power output is rated as 150 watts into 8 ohms, 300 watts into 4 ohms, and 400 watts into 2 ohms at 1kHz. 
• Each pair of outputs can be bridged, capable of producing 740 watts into 8 ohms (clipping protection limited), 750 watts into 4 ohms, and 450 watts into 2 ohms at 1kHz. 

The look and feel of Scandinavia 

We believe that every aspect of our products – the way they look, the satisfying feel of the controls – contributes to the overall experience of living with Primare. As a result, Primare products exude the hallmarks of Scandinavian design – simple, elegant designs, with approachable and easy to understand functionality. An example of this is the idea of being inconspicuous, of not drawing undue attention, which is inherent in the physical design of the A35.8 Prisma, both in its compact size as well as the ingenious standby button hidden within the centre of the engraved Primare logo on the front panel
