Amplifier technology 

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. 

System Configurations 

The bridging capabilities of the A35.8 allow it to be used in a variety of system configurations, with or without the addition of a stereo amplifier, to suit most multi-channel system requirements. A few examples: 

  • 5.1, 7.1 and 5.1.2 channel systems can be powered by a single A35.8 
  • 5.1.4, 7.1.2, 7.1.4 channel systems can be driven by combining an A35.8 with a number of A35.2 stereo amplifiers 

  • 9.1.6 and 13.1 Auro 3D systems can be configured using two A35.8 amplifiers

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

    A35.8 – Customized Performance

    “With two bridged pairs of channels, the bass gains another ounce of impact and definition, but at the same time it is even more permeable for the mids, which can now breathe even more freely. In addition, especially with the bowed bass at the beginning of the piece, it is noticeable how the attack and decay of the tones are traced even more finely. The stage changes not significant in their extent, but the individual sound events now seem to be even better separated. earth shattering? Not really, but after two or three changes I can blindly tell the difference between single and bi-amping – based on small but clearly understandable differences that I don’t want to do without afterwards because they simply add that much more fun to listening to music worries.

    The experiment in search of the next bit of sound quality can therefore be considered an absolute success – especially when you consider that the additional costs are very reasonable and the eight-channel power plant takes up no more space in the rack than a stereo power amplifier.”

    *Joint award with Home Theatre audio expert group*

    “Designed for both the home theatre audio and hi-fi worlds, Primare’s multichannel 35 Series amplifier deploys eight bridgeable channels of potent, dynamic Hypex Ncore amplification, and then lets the user decide what to do with them. For a home cinema, the A35.8 can spread its output across a surround array or be used to bi-amp the front LCR speakers; in a two-channel system, bridged pairs bring phenomenal power and grip, and all eight amps can be put to work on loudspeakers with a split crossover. This is a flexible, innovative, and imperious-sounding amplifier, in a stylish, understated chassis typical of the brand.”

    Primare A35.8 Eight-Channel Power Amplifier Review

    There are many uses for power, and in my months with the A35.8, I explored most of them. At no point did Primare’s eight-channel design fall short in quantity or quality of amplification, making “bigger without change” and without complaint, no matter what I sent its way. That earns the A35.8 a straight “A” in my book”

    A35.8: Complete Freedom

    “In the final analysis I can state that Primare has succeeded very well in their intentions to produce a high-quality and supremely flexible multi-channel amplifier. And the number of channels was not simply taken out of thin air, as it can, for example, be run fully bridged to bi-amp a pair of speakers with two sets of speaker connectors, and thereby use all of those eight channels.”

    Primare A35.8 – the bridge between film and music

    “What a wonderfully fast, lively and flexible amplifier the A35.8 is. Not only can it control eight speakers, it is possible to control four power-hungry speakers via bridge mode. Or bi-amp a stereo set. And yes: that works great! However, you have to take into account the standard low gain. And you do need a preamp with four outputs. The Primare Pre35 can do that job. All in all a beautiful duo that can do much more than most enthusiasts will think!”

    Home Cinema Choice A35.8 Review

    “Overall, Primare’s A35.8 is a classy bit of kit, with a performance (plus a luxurious design and build) that feels commensurate with its not inconsiderable asking price. It’s more than capable in terms of power output to handle hungry speakers, and does so while keeping distortion or unwanted colouration at bay. Being able to bridge its amp channels to suit your requirements is another feather in its cap, as is its refined and insightful nature with music. I rate this an A-grade amplifier.”

    A35.8 HFN Review

    “The channel count reaches eight because, sensibly, Primare has built it around bridgeable pairs, which means none need go to waste in a home cinema environment. Primare’s most powerful amp to date will service the most ambitious bi-, tri- or quad-amp loudspeaker solutions… a rare product that straddles the worlds of multichannel and hi-fi with aplomb. Its amp stage delivers scads of umblemished, responsive power, while its bridging ability is there to keep hungry loudspeakers well fed – and all this comes from a box no bigger than some monoblocks…”
