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 INSERTA 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 polar-
ization 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.
REFER SERVICING TO QUALIFIED SERVICE

REPLACEMENT PARTS LIST FOR DCM4000 AMP
This symbol is intended to alert the
user to the presence of uninsulated
“dangerous voltage” within the prod-
uct’s enclosure that may be of suffi-
cient magnitude to constitute a risk of
electric shock to persons.
This symbol is intended to alert the
user to the presence of important
operating and maintenance (servic-
ing) instructions in the literature
accompanying the appliance.
CARVIN ENGINEERING DATA
OPERATING MANUAL
The DCM4000 was designed for pro sound companies and individuals who require
huge amounts of clean RMS power to drive large, professional speaker systems
and arrays, as well as high powered monitor systems. This was the main idea and
motivation behind the concept of the
DCM4000: Twice the power - same number
of rack spaces. Another advantage of the
DCM4000 was even more obvious -
1400 Watts x 2 at 8 ohms in bridge mode!
A TON OF POWER X 4
Each DCM4000 incorporates four separate 1000 Watt RMS amps and is pow-
ered by redundant toroid power supplies that are totally independent of each other.
It’s like having two complete 2000 watt amps in one 3 space package. The only
thing they share is the AC cord so if one of the two primary fuses fails, the other
amps are not affected. These four amps can be used to power four separate speak-
ers from four different sources (this is ideal for monitor systems). Each side can
be bridged to become two 2000 Watt amps (great for high powered speakers and
subwoofers like the Carvin TCS series). Each side can even be paralleled and then
chained together to be fed by a single input source (perfect for arrays with a large
number speakers).
AWESOME SOUND!
What good is a ton of power if it doesn’t sound great? The Carvin DCM4000
is an incredibly transparent amp sporting slew rates well over 50 VmS. With mas-
sive dual power supplies and huge reserve capacitors for on-demand power, the
DCM4000 delivers pure, uncolored sound at full output; with tight, punchy lows
and open, transparent highs – without a hint of distortion.
RUGGED TO THE EXTREME
These pro amplifiers are completely protected from any kind of abuse that might
pop up in a typical road rig – thermal, over-current, short-circuit, voltage spikes,
“hot-swapping” speakers – the
DCM4000 is designed to protect itself and be right
back up and running as soon as the problem is remedied. The all-steel, front &
rear rack-able chassis can take whatever abuse is thrown at it. These amplifiers
are just what the real pro wants - “rack’em and forget’em”.
COOLEST COOLING
Carvin’s exclusive “Wind-Tunnel” heat-sink with dual “push/pull” 105 CFM fans,
ensures full, uninterrupted RMS power delivery without over-heating concerns. These
are continuous-duty amps meaning that if you drive them at full power, 24 hours
a day, they won’t shut down. And, be assured that you’ll get your full power in
RMS watts, not pulse or peak power.
DISTORTION-FREE LIMITERS
The purpose of a limiter is to hold down peaks so the amp won’t distort even with
extra hot input signals (this protects your expensive speakers). In addition, a well
designed limiter can increase your amp’s average output as much as 3 db. Part
of Carvin’s design uses the more expensive, distortion-free linear “opto isolators”.
Unlike amps that use FET controlled limiters which can inject small amounts of
distortion, the DCM Series limiters keep your sound pure and uncolored!
FRONT & REAR PANELS
Along with the normal Gain controls and Signal, Clip, and Power indicators, we’ve
included a very useful “Bridge Mode” indicator to avoid inconvenient or even costly
hook-up mistakes. On the back panel you get a male and female XLR input per
amp (perfect for daisy-chaining amps). The
DCM4000 features a speaker output
section with professional high current Twist-Lok and Banana/Binding Post con-
nectors to mate with any pro speaker rig. Each dual-amp side features switches
for Bridging, Parallel input, Ground Lift, Limiter, and Sub-sonic filter.
RECEIVING INSPECTION
INSPECT YOUR SPEAKER FOR ANY DAMAGE which may have occurred during shipping.
If any damage is found, please notify the shipping company & CARVIN.
SAVE THE CARTON & ALL PACKING MATERIALS. In the event you have to re-ship your
unit, always use the original carton and packing material. This will provide the best possi-
ble protection during shipment. CARVIN and the shipping company are not liable for any
damage caused by improper packing.
SAVE YOUR INVOICE. It will be required for warranty service if needed in the future.
SHIPMENT SHORTAGE. If you find items missing, they may have been shipped separately.
Please allow several days for the rest of your order to arrive before inquiring.
RECORD THE SERIAL NUMBER on the enclosed warranty card or below on this manual
for your records. Keep your portion of the card and return the portion with your name and
comments to us. Or you may register online at www.carvin.com/registration
