Inside the I15 Prisma's petite case you'll find a smooth-sounding DAC and a cool-running Class D amplifier with surprising poise and punch.

In Primare's I15 family of integrated amplifiers, the I15 Prisma is the brainy one. Think of it as a one-box solution for most people's digital music needs. You can connect one analog and multiple digital music sources, or choose from an array of wireless streaming options.

This svelte 3/4-size component includes a nice remote, but the best way to navigate your music options is with the clean, intuitive Prisma app, available for both iOS® and Android™ devices.

Primare's Class D amp sounds... classy

The amplifier section of the I15 Prisma delivers 60 watts per channel into 8 ohms, and 100 watts per channel into 4 ohms. It's rated conservatively — when you connect it to your speakers, you'll swear the actual power output is higher.

Primare has been refining their Class D technology over the past ten years, and reviewers describe the sound of their latest amps as unfailingly smooth and natural.

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. 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 I15 Prisma also features Chromecast built-in and 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 I15 Prisma is also Roon Ready (firmware update required).

The built-in high-performance 32-bit DAC presents virtually any digital music source with a level of clarity and detail you may not have experienced before.

Stylish sound from Scandinavia

Founded in Sweden in the mid '80s, Primare relies on a talented team of designers to create its innovative high-end audio components. Among audiophiles, their equipment is admired both for its exceptional sound quality and its elegant appearance.

Amplifier & Audio Section

Hypex UCD102 Amplifier Module: The I15 Prisma employs a specially made Hypex UCD102 amplifier module, fed by Primare's custom heavy duty switch mode power supply and carefully crafted analog input stage that provides a dynamic and detailed sound. The Hypex amplifier module is rated a 60 watts x 2 channels into 8-ohms and 100 watts x 2 channels into 4-ohms. Given the speed at which the Hypex amplifier module is able to deliver power to the speaker, a switch mode power supply was the only choice because it allows for rapidly varying demand, providing much more stable voltage, with ancillary capacitive storage to meet peak transient burst requirements.

High Performance 32-Bit Stereo 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 I15 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. The 32-Bit stereo 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.

Simple Circuitry Design: The I15 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.

Analog Input & Output: The Primare I15 Prisma is outfitted with one stereo RCA analog input and one stereo RCA analog output. The analog input can set to a fixed or variable gain. The variable gain is adjustable from -30dB to 0dB in 1dB increments. The stereo RCA pre-out can be used to connect an external power amp.

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 Primare I115 Prisma is equipped with three toslink optical digital inputs, one mini-toslink optical digital input, and one coaxial (RCA) digital input. The digital inputs support up to 24-bit/192kHz stereo (2ch) PCM audio. There is also a digital coaxial (RCA) output for connect to an external DAC.

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

Binding Posts: The Primare I15 Prisma is equipped with four heavy-duty, gold-plated binding post terminals to connect a single pair of loudspeakers. The binding post terminals will accept bare wire (up to 10AWG), pin-connectors, and banana plugs (single only). You can connect a single pair of 4 ohm to 8 ohm speakers.

Volume Settings: The integrated amp 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 integrated amp 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 I15 Prisma integrated amplifier 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 2 , Spotify Connect, DLNA/UPnP, and Roon.
