A compact control center for a 2-channel music system

Primare's handsome SC15 Prisma is a fine-sounding stereo preamp designed for the ways we listen today. You can connect one analog and multiple digital music sources, or enjoy high-quality wireless streaming from mobile devices or the web. The SC15 Prisma's 3/4-size footprint makes it a smart option for sweetening the sound in multi-purpose living spaces.

The built-in high-res-capable DAC presents digital sources with striking clarity and detail. If you have a CD collection, a great way to enjoy it is to match Primare's DD15 CD transport to the SC15 Prisma's DAC section. Want to connect a turntable? Simply add a phono preamp — Primare's R15 is a great match, both sonically and visually.

The SC15 Prisma comes with a nice remote, but the best way to navigate your music options is with the clean, intuitive Prisma app, available free for both iOS® and Android™ devices.

The brilliant Prisma network player

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.

SC15 Prisma Preamplifier: The Primare SC15 Prisma combines a high-performance DAC (digital-to-analog converter), network audio player, and preamplifier into one compact chassis. The SC15 Prisma offers a comprehensive input and output options, featuring both analog and digital inputs, as well as Network and Bluetooth connectivity.

Simple Circuitry Design: The Primare SC15 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.

High-Performance 32-Bit DAC: In order to allow for playback of virtually any digital source with absolute accuracy and musicality a high performance 32-bit stereo DAC chipset was selected for the SC15 Prisma that is capable of achieving -112dB THD+N with 120dB (stereo) S/N, while supporting up to 768kHz PCM and 256/11.2MHz DSD. This high-performance DAC integrates a newly developed switched capacitor filter "OSR Doubler" that greatly reduces sound degradation from noise shaping, achieving a flat noise floor up to 200kHz. An innovative design technique utilizing a symmetrical layout for the left and right channels prevents signal quality deterioration, and a 32-bit digital operation block provides full 32-bit processing.

Analog Input & Output: The Primare PRE35 Prisma is equipped with an unbalanced stereo analog audio RCA input and output. There is a single pair of stereo analog audio RCA input for connecting an external audio source, as well as a single pair of stereo analog audio RCA outputs to connect the preamplifier to a powered amplifier.

Digital Inputs & Output: The PRE35 Prisma is outfitted with three optical (toslink) digital inputs, one coaxial (RCA) digital input, 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 SC15 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 SC15 Prisma preamplifier offers wired and wireless network connectivity. It's outfitted with an Ethernet (RJ45) jack for a hardwired connection to your network router. 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.

Note: A network connection is required for Chromecast Built-In , AirPlay, Spotify Connect, DLNA/UPnP, and Roon.
