D-20 Amplifier

D-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 pick up four channels of networked audio, via Dante·, which is then converted using 24 bit 96kHz DACs.

Within this 1U chassis, the amplifier also features individual 70/100V line drive·, an auto standby power mode, 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 D-40, and has a PFC enabled universal mains supply for worldwide use.

Then, connect to a D-series 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.
