The control center of a no-compromise audio system

Primare's PRE35 Prisma preamplifier is an exceptional system control center, providing endless ways to enjoy all of your 2-channel music. For digital music sources there's an excellent DAC section, along with one of the most complete and well-thought-out network players we've seen. The PRE35 Prisma's back panel bristles with a comprehensive array of connections including both XLR and RCA inputs and outputs.

About the only thing this preamp lacks is a turntable input, and vinyl fans can fix that by adding Primare's R35 phono preamp, which is an ideal match, both sonically and visually. And if your system is based on conventional sources like a CD player, consider the analog-only PRE35 preamp, which lacks the DAC and network player.

The PRE35 Prisma deserves to be used with high-quality amplification, and it achieves a special synergy when paired with Primare's powerhouse A35.2 amplifier.

A preamp/DAC offers many advantages

The PRE35 Prisma handles the tasks of a conventional preamp — selecting and switching among your music sources — with precision and ergonomic ease. The carefully crafted fully balanced circuit design keeps signal paths as short as possible, resulting in exceptionally low noise and distortion.

By placing the DAC in the same case as the preamp, you save on the cost of interconnect cables while keeping the signal cleaner. The PRE35 Prisma's built-in high-performance 32-bit DAC was engineered with the latest audio processing. Feed it digital signals from your CD player or Blu-ray player and enjoy a level of clarity and detail you may not have experienced before. If streamed or downloaded music is a big part of your listening, you'll love the easy access that Prisma provides.

Primare's Prisma network player does it all, and does it well

Prisma is actually a bundle of technologies that provides a broad range of network music player features and functionality. It makes it easy to discover, explore, and share high-performance music playback, whether the source is stored or streamed, wired or wireless. Whether you're listening to Spotify® or files from your NAS drive, the Prisma control app provides total system management from your mobile device.

The PRE35 Prisma also features Chromecast built-in and Apple AirPlay 2, streaming portals that let you connect directly to hundreds of streaming applications. Chromecast built-in streams audio directly from the cloud, so you get the highest sound quality. It's even possible to enjoy high-res music (up to 24-bit/96kHz) from services like TIDAL and Qobuz. The PRE35 Prisma is also Roon Ready (firmware update required).

PRE35 Prisma Preamplifier: The Primare PRE35 Prisma incorporates a high-performance DAC (digital-to-analog converter) and network player module within a fully balanced preamplifier platform to create a versatile system control center for your home audio entertainment. The PRE35 Prisma preamplifier provides umprecedented low noise and distortion free selection and transmission of any analog input, as a result of the carefully crafted fully balanced circuit design benefitting from the use of a 4-layer main board to achieve the shortest possible signal path. The PRE35 Prisma offers a comprehensive input and output options, featuring both balanced XLR and unbalanced RCA connection, as well as optical and coaxial digital inputs; plus USB, Bluetooth, and Network connectivity.

Simple Circuitry Design: The Primare PRE35 Prisma utilizes simple circuitry design and architecture with ultra-short signal paths, double-sided circuit boards, and surface-mount components for natural and unaltered sound.

  • Ultra-Short Signal Paths: Ultra-short signal paths are used so that each individual component and sub circuit operates sympathetically to achieve a cohesive whole. Elegant and simple electrical designs are used in even the most complex product, utilizing ultra-short signal paths with all gain in one device whenever possible. Ultimately, this results in fewer, higher quality parts for a reduction in associated distortions and an increase in overall electrical efficiency.
  • Double-Sided Circuit Board Construction: 2 and 4-layer double-sided circuit board construction allows for the most direct and efficient layout of circuit components not only for the shortest signal path, but also to more easily achieve a sympathetic layout of circuit and sub-circuit components for best performance.
  • Surface-Mount Components: Surface-mount components are used whenever possible as this allows for direct connection of the circuit device or component to the circuit board trace with the solder being used solely to mechanically hold the part in place. The elimination of the small metal lead or wire at each connection point in a more conventional large scale circuit device or component cumulatively shortens the signal path.

Premium 32-Bit DAC: At the heart of the Primare PRE35 Prima's DAC stage is a premium 32-bit stereo DAC that is capable of achieving -128dB (stereo) S/N and -116dB THD+N, while supporting up to 768kHz PCM and 11.2MHz DSD. This ability to handle higher resolution file formats will allow for the potential of future software upgrades.

Balanced & Unbalanced Connectivity: The Primare PRE35 Prisma preamplifier is equipped with both balanced XLR and unbalanced RCA inputs, outputs, and pre-outs. Balanced connections guard against induced noise and allow long cable runs without compromising sound quality.

  • XLR & RCA Analog Inputs: There are two pair pair of stereo balanced XLR inputs and three pair of stereo unbalanced RCA inputs to connect your external analog audio sources.
  • XLR & RCA Pre-Outs: There are two pair of stereo balanced XLR pre-outs and one pair of unbalanced stereo RCA pre-outs to connect an external power amplifier or amplifiers.
  • RCA Line Output: A stereo RCA line-level output that can be used for audio dubbing.

Note: There is no phono input. If you want to connect a turntable, you'll need a turntable with a built-in preamplifier or an external phono preamp (sold separately).

Digital Inputs & Output: The PRE35 Prisma is outfitted with four optical (toslink) digital inputs, two coaxial (RCA) digital inputs, and one coaxial (RCA) digital output. The digital inputs and output support up to 24-bit/192kHz stereo (2ch) PCM audio.

Note: The digital input and outputs do not support multichannel audio formats, such as Dolby Digital & DTS.

WiSA Ready: Via a future Firmware update (no ETA), the PRE35 Prisma will support WiSA. Thanks to WiSA technology you can create a wireless 2ch speaker system with low-latency (5.1 milliseconds), seamless synchronization (+/-1.0 microseconds), and high-fidelity audio (24-bit/96kHz). WiSA has been adopted by a number of speaker manufacturers - including B&O, Harmon Kardon, Golden Ear, Klipsch, Platin, and System Audio - with many more to come.

Fixed or Variable Gain: The analog & digital inputs can be set to a fixed or variable gain. The variable gain is adjustable from -30dB to 0dB in 1dB increments.

Volume Settings: The preamplifier has a volume range of 0 to 99. You can adjust the units start up volume (0-60), maximum volume (0-99), and mute volume level (0-30).

Auto-Sense & Auto Standby: The Auto-Sense function automatically turns on the preamplifier when it sense an audio signal. The unit will enter Standby automatically when there is no audio signal and no user interaction for 10, 15, or 20 minutes. These functions can also be turned off.

Network & Multiroom Audio

Wired or Wireless Network Connectivity: The Primare PRE35 Prisma preamplifier offers wired and wireless network connectivity. It's outfitted with two Ethernet (RJ45) jacks (LAN In/Lan Out) for a hardwired connection to your network router and a wired daisy-chain network connection to another network enabled device. It also features built-in dual-band 2.4/5GHZ WiFi (802.11 a/b/g/n/ac) for a wireless connection to your WiFi router. Two antennas are included and must be installed to make a wireless WiFi connection.
