The DCML power amps deliver exceptional sound/reliability, ultra-light weight 15lb (6.4kg) from 1500w to 3800w and it’s made in the USA. You’ll appreciate

the ultra-light feature, which comes in part from its heavy-duty aluminum frame. High power, uncompromised sound and maximum reliability is at its best for both touring systems and fixed installations. The concert stage is the ultimate test of professional audio. Concert audio has to be uncompromising, reliable and efficient and that’s where the DCM has made its mark night after night, year after year serving top artists and concert venues for the last decade. TheDCM isaproven American made workhorse backed by 40 years of manufacturing excellence.

HIGH POWER TOPOLOGY

The CLASS A/B linear topology features high current bipolar output devices that reduce distortion to a near theoretical zero .03% THD while delivering high slew rate performance for crystal clear highs and chest pounding bass – every note is vibrant, pure and natural. The DCM’s headroom reveals its high dynamic power from the Switchmode power supply that operates at 100,000 Hz. Extreme currents are delivered to the most demanding 4 ohm bridged subwoofer systems. The high efficient Switchmode supply is a league above toroids saving not only AC power from the wall but reducing internal heat. The DCM easily handles the most difficult mismatched or reactive loads and is AC generator friendly. The soft-start gently turns the DCM on to prevent tripping AC breakers. The DCM1000L and DCM2000L feature Class D output raising power amp efficiency even higher! The DCM1540L, DCM3000L and DCM3800L feature linear Class A/B output stages.

COOL EFFICIENT DESIGN

A high efficiency heat transfer system offers the most advanced cooling, which is one of the keys to reliable power. Five high ratio 6063-T5 flow-through aluminum heat sinks remove heat fast with multi-speed fans that runs quiet under 2 ohms loads (except DCM1540L). Air is pulled from the rear and exhausted to the front to keep the rear of your rack cool. R & D designed a “direct mount” system for the power output devices to be directly mounted to the heat sink, which eliminates any thermal barrier to keep your amp running cool.

FRONT PANELS & CONNECTING UP

The DCM Series feature front panel signal, peak and protect LEDs which let you monitor the status of the amp. Both channels use detente level controls allowing you to see your settings at a glance. Balanced TRS & XLR input connectors are used to eliminate hum & noise. Speaker outputs feature heavy-duty binding posts, and combo Speakon™ / 1/4” jacks.

The rear professional accessory group offers a GROUND switch to remove the chassis ground from the XLR input. A Parallel input switch connects the inputs together eliminating Y cables for patching multiple amp systems. The accessory group also features a bridge mode switch to deliver twice the power into a “mono” load or a 70V distribution system, and a limiter ON/OFF switch gives the choice of using the internal limiter circuitry.

RECEIVING INSPECTION—read before getting started
