Overview

The PRE35 PRISMA stereo preamplifiers feature two XLR inputs and outputs. With the Prisma module, the PRE35 PRISMA provides multi-room/multi-zone connectivity and control for playback of stored and streamed media, wired or wireless, all managed from a mobile device via a dedicated system control app.

In addition to Bluetooth, AirPlay 2, and Spotify Connect, Prisma integrates Chromecast, a unique streaming portal enabling effortless direct connection to hundreds of streaming apps, including Roon, for optimal performance and user experience.

Unique for a high-performance preamplifier, the PRE35 Prisma includes WiSA wireless speaker connectivity.

WiSA system features:

High-resolution audio quality; WiSA transmits 24-bit at 48 kHz / 96 kHz.
Near-zero latency: less than 1/10th the latency of Bluetooth audio devices.
Instant synchronization - speaker synchronization in less than 1/1,000,000 second.

To enable playback of virtually all digital sources with absolute precision and musicality, the PRE35 Prisma’s DAC module reproduces high-resolution sound as close as possible to the original source. Inputs include four Toslink, three RCA (SPDF), and one USB-B digital. The USB-B input allows playback of files up to PCM 768 kHz / 32bit and DSD256 / 11.2MHz. An RCA digital output is included, allowing transmission of digital signals.
