D-120 Amplifier

OHM’s collaboration with MC2 Audio continues with five new amplifiers being added to the current product list.

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 two channels of networked audio, via Dante, which is then converted using 24 bit 96kHz ADCs.

Running cool in even the most difficult conditions, the D-120 can deliver 2 x 4600W into 4 ohms with all channels driven,
and over 6000W per channel into 2.7 ohm loads, with outstanding distortion and noise figures right up to maximum output.
This power is maintained even with reduced mains voltages thanks to generous limiter headroom.

Connect to a D-Series DSP amplifier using a single CAT5 cable to realise a stereo 3 way system with no further external processing required. Switch back to analogue to use as a powerful traditional dual mono amplifier.

Link adjacent inputs for total flexibility in either analogue or digital mode.
