SAFETY INSTRUCTIONS (EUROPEAN)
The conductors in the AC power cord are colored in accordance with the following code.
GREEN & YELLOW—Earth BLUE—Neutral BROWN—Live
U.K. MAIN PLUG WARNING: A molded main plug that has been cut off from the cord is unsafe.
NEVER UNDER ANY CIRCUMSTANCES SHOULD YOU INSERT A DAMAGED OR CUT MAIN PLUG
INTO A POWER SOCKET.
IMPORTANT! FOR YOUR PROTECTION, PLEASE READ THE FOLLOWING:
WATER AND MOISTURE: Appliance should not be used near water (near a bathtub, washbowl,
kitchen sink, laundry tub, in a wet basement, or near a swimming pool, etc). Care should be taken
so that objects do not fall and liquids are not spilled into the enclosure through openings.
POWER SOURCES: The product should be connected to a power supply only of the type
described in the operating instructions or as marked on the appliance.
GROUNDING OR POLARIZATION: Precautions should be taken so that the grounding or
polarization is not defeated.
POWER CORD PROTECTION: Power supply cords should be routed so that they are not likely
to be walked on or pinched by items placed upon or against them, paying particular attention to
cords at plugs, convenience receptacles, and the point where they exit from the appliance.
SERVICING: The user should not attempt to service the appliance beyond that described in the
operating instructions. All other servicing should be referred to qualified service personnel.
FUSING: If your unit is equipped with a fuse receptacle, replace only with the same type fuse.
Refer to replacement text on the unit for correct fuse type.
This symbol is intended to
alert the user to the presence
of uninsulated “dangerous

enclosure that may be of suf-
ficient magnitude to constitute a risk of
electric shock to persons.
This symbol is
intended to alert the
user to the presence

CARVIN ENGINEERING DATA
OPERATING MANUAL
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 af-
ter year serving top artists and concert venues for the last decade. The DCM is a prov-
en 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 cur-
rents 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 alu-
minum 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.
CONSTRUCTION
The DCM construction starts with a heavy 2RU aluminum chassis. All printed
circuit cards are double-sided FR4 military-grade fire retardant with plated through
holes - soldered under, on top and through each component. SMT - surface mount
technology offers “shock-proof” protection. The CB and CE safety seal assure that
each DCM meets strict standards for service anywhere in the world. Auto switches
from 120VAC 60Hz or 240VAC 50Hz - no manual switch to change.
