Overview

4 Channel Network Audio Power Amplifier, 4x 350W / 4 ohms

Delta Series offers the assurance of the highest quality audio power amp technology with future proofing via the inclusion of simple to use digital audio networking.

A rear panel switch allows the amplifier to accept either four channels of analogue audio or pic up four channels of networked audio , via Dante, which is then converted using 24 bit 96kHz DACs.

Then, connect to a Delta DSP amplifier using a single CAT5 cable to realise a stereo 4 way system - no external processing required. Run bridged channel pairs or link adjacent inputs for total flexibility in either analogue or digital mode.

Within this 1U chassis, the amplifier also features individual 70/100V line drive, an auto standby power mode (with wake-up < 1s), tuneable fans adaptable to different level/performance scenarios, and GPIO for remote control and monitoring. The amplifier also supports the back-up amplifier inputs as on the Delta 40, and has a PFC enabled universal mains supply for worldwide use.
