HELP SECTION
1) WILL NOT TURN ON
Check the power to the unit. Check for tripped main circuit breakers, unplugged extension cords
or power-strip switches that may be turned off. Check the amps circuit breaker on the rear panel.
If the black curved center button is in the out position, push it in to reset. If the breaker contin-
ues to trip, check your speaker cables and total speaker impedance. If the amps circuit breaker
will not reset, then the amp will require servicing.
2) MAINTAINING YOUR EQUIPMENT
Avoidspilling liquids orallowing any otherforeignmatter inside theunit. Thepanel of yourunitcan
be wiped from time to time with a dry or slightly damp cloth in order to remove dust and bring back
the new look.
As with all pro gear, avoid prolonged use in caustic environments (salt air). When
used in such an environment, be sure the amplifier is adequately protected by rack, covers, etc..

The DCM1001 professional Dual Graphic amp was designed utilizing Carvin’s
37 years of experience in power amp & equalizer technology. The DCM1001 is
Ideal for monitor set-ups because its small size, light weight, high power, and
EQ capabilities allow you to use only one piece of gear in place of two or three.
This saves you work, rack space, and money. The thick steel face plates, large
recessed knobs, and heavy-duty steel chassis reflect the manufacturing quality
within. All models carry the CE approval for world-wide use.
PURE—TRANSPARENT SOUND
Carvinconsidersthesoundofanampequallyimportantasitsreliability. Toinsure
pure, uncolored sound, we designed one of the fastest responding power amps
on the market today. High slew rates greater than 45v/µs deliver superb transient
response. Highfrequenciesaretransparentandopen—evenatextremelevels. Linear
feedbackcircuitsreducedistortiontonearthetheoreticalzerolimit,preventingany
type of harshness which would lead to ear fatigue. The DCM Series amps deliver
flat, transparent, unaltered sound—especially important to the studio user. And
youcandriveanytypeofreactiveloads,including70Vtransformerdistributionsys-
tems. These amps are designed to deliver non-stop, continuous power and are
completely protected from heat and short circuits.
ULTRA RUGGED FOR TOURING
Every chassisis madefrom heavy-duty16 gaugesteel thatis galvanizedbefore
being painted to prevent rust. All internal cabling is neatly tied and harnessed.
Every circuitcard is MILSPEC, double-sided, through-holeplated, fire retardant
FR-4glassepoxy. Thisinsuresthatthesolderflowsonthetop,bottomandthrough
each hole of every component, preventing components from shaking loose—
even through constant tour use. Heavy-duty XLR connectors, power switches,
recessed knobs, steel front panels all give the DCM amps a “tank-like” ability to
handle rough, touring transport.
TOTALLY MODULAR
With the DCM Series, Carvin brings you totally modular construction. If you
ever need an I/O (input/output) connector card because a connector wore-out,
just unplug it and re-install the replacement card in minutes. You don’t have to
de-solderanything. This appliestoeveryaspect ofthe DCMSeriesampsinclud-
ingthepowersupply, powercards,heatsinksand fans. Everythingisconnected
byheavy-dutyAMP™andMOLEX™typeconnectors foreasyreplacement—even
the Toroid transformer is a total plug-in.
HEAVY-DUTY COOLING
Carvin offers up to 30% more cooling than comparable amps rated at the same
wattage. This means that the DCM Series are thermally “over-engineered” to be
sureheatwill neverbeaconcern. Even outdoorconcertsindirect sunlightwillnot
cause thermal shut down. Carvin uses precision 6063 T-5 aluminum high ratio

speed fans cool your amp quietly.
LOSE THE WEIGHT...NOT THE PERFORMANCE
For some companies weight reduction means cost reduction. Carvin however,
uses expensive TOROID transformers to reduce weight. Toroids deliver massive
amounts of “on demand” current for continuous 2 ohm operation. This gives the

DISTORTION-FREE LIMITERS
While most amps do not offer built-in limiters, this is an important feature to look
for. 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
welldesignedlimitercan increaseyouramp’saverage outputasmuchas 3db. Part
of Carvin’s design uses the more expensive, distortion-free linear “opto isolators”.
Unlikeampsthat use FET controlledlimiters which can injectsmall amounts of dis-
tortion, the DCM Series limiters keep your sound pure and uncolored!
FRONT PANEL & 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 precision level controls allowing
youtoseeyoursettings ataglance. Balanced1/4phone& XLR inputjacksareused
to eliminate hum & noise. Speaker outputs feature 1/4” jacks, high current Twist-
Lock & heavy-duty binding posts that accept up to a 50 amp #7 speaker wire.
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 of
bothchannelstogethereliminatingYconnectorsand allowingamppatchinginmul-
tiple amp systems. The accessory group also features a bridge mode switch for
delivering full power into a 70V distribution system and a limiter ON/OFF switch
that gives you the choice of using the internal limiter circuitry.

1. MOUNTING
A sturdy one piece 12 gauge steel face plate accommodates easy transporting along with facilitating
rackinstallation.Therack mountingholesaredesignedonISO standard spacing. Four10-32x.5”phillips
machine screws are normally used to secure the amp. Rear support brackets are not required.
2. POWER SWITCH/INDICATOR/FUSE
Check the power amp connections and verify the AC line power source before engaging the POWER
switch. The yellow LED unmistakably indicates that all circuits are properly powered up. Yellow is used
so the operator can see the red indicators (clipping or protect) from a distance. If the yellow power LED
does not light up, remove the lid and replace the fuse located in the back corner where the
AC cord connects to the circuit board. (DCM1001: 25AMP slow blow)
3. CHANNEL LEVEL CONTROL
Aprecisioninput LEVEL attenuateisusedto adjust thevolumelevels. Todeliver theampsmaximumpower
without reducing the headroom of the signal source, the level controls should be turned full on.
4. CHANNEL SIGNAL INDICATOR
ThegreenSIGNALLEDindicatorswillstarttoflashwhenthereisasignalpassingtoyourspeakers(-30dBM).
This lets you know when the amp is passing a signal to your rear speaker connectors.
5. CHANNEL CLIP INDICATOR
TheredCLIPLEDindicatorswillstarttoflashwheneachchannelhasreacheditsmaximumoutput. Occasional
flashingcausedbylowerbassfrequenciesisOK. However,consistentflashingcausedfromhigherfrequencies
may damage high frequency drivers (excessive distortion). This does not cause damage to the amp.

that frequency, thus allowing more gain (volume) before feed-back. For tone control, move the sliders
up or down from their center detent positions to suit your taste. USETHEIN/OUTSWITCHESTOBYPASSTHEEQ’s.
7. PROTECT LED INDICATOR
The red PROTECT LED provides the operator with information about the status of the amplifier. The
PROTECT LED can come on under 3 different conditions (when this happens both channels are muted
by disconnecting the output speaker relays protecting your speakers);
1) During power-up, the amplifier stays in a muted state for approx. 3 sec until it determines that
everything is functioning normally (no output shorts or over temp conditions).
2) Bothchannelsaremuted whentheoutputloaddrawsexcessive current oradirectshortis detected
caused by a shorted speaker cable or speaker system. Reset this condition by turning the amp off
fortwo seconds andthen onagain. Check forshorted cablesand the totalspeaker systemimped-
ance connected to each channel (2 ohms is the minimum per ch or 4 ohms BRIDGED).
3) Overheating is usually determined when the amp stops in the middle of a performance and the
PROTECT LED comes on. If this is the cause, leave the amp on for the fan to cool the amp down.
The amp will automatically reset within 1 to 3 minutes and the PROTECT LED will turn off when
ready. Check for the following conditions; a) The rear intake air is restricted, b) The intake air is
extremely warm, c) The front exhaust vents are restricted, or d) Excessive speaker load (try other
speakers or remove speakers if you have more than one connected to each channel). Again, the
minimum impedance is 2 ohms per ch or 4 ohms BRIDGED)
REAR PANEL
8. XLR CHANNEL INPUTS
Formost professionalapplications, usethe XLRbalanced inputs. This will help toreduce humand allow
of longer cable runs from your signal source (mixer, etc). Because this is a balanced input, the gain will
be6dBhigherthanusingthe1/4” input jackwithnonbalancedlines. XLRpinconfiguration:Pin1:Grounded
through the GROUND LIFT switch, Pin 2: positive Balanced signal and Pin 3: negative Balanced signal.
9. 1/4” CHANNEL INPUTS
These1/4”TRSphonejacksaredesignedtoreceiveeitherbalancedorunbalanced inputsignals. Balanced
signals coming into this jacks should be wired with the connector’s tip going to signal + and the connec-
tor’s ring to signal -. The connector sleeve is then tied to ground through the GROUND LIFT switch.
10. PARALLEL OR “Y” INPUTS
Therear PARALLELswitchallows youto drive both channels fromeither input. Allsignals enteringany
input will be available on both channels. This eliminates Y adapter cables. This feature is used to “daisy
chain” one piece of equipment to another. Just plug into the unused INPUT (1/4” or XLR) and it will
become an output for other equipment.
11. INPUT GROUND LIFT
Many times sound systems are connected in such a manner to cause a grounded loop with the inputs
that result in audible hum. The input GND LIFT (1/4” & XLR) switch on the rear panel will help eliminate
this problem. If not, another way to eliminate ground loops is to install a “line matching” transformer
between the amplifier input and the signal source and cut the ground wire to PIN 1.
12. LIMITERS
To activatetheLIMITERS,engagetherearlimiterswitch. Thebuilt-inprofessionallimitersarerecommended
to hold down peaks that could cause early distortion. Limiters will help to raise the average power so that
you can get more output from each channel. To check the effectiveness of the limiters when the channel
starts to distort (under the amps full output), engage the limiters and hear the reduction of the distortion. If
thedistortionstops,youcanturnthechannelupformorepower. Thelowerbassfrequenciesaremostaffected.
WARNING: Do not check in an environment where the sound level could damage your ears!
13. SPEAKER OUTPUTS
The standard 1/4” SPEAKER jacks are used for lower power applications. The Twist-Lok connections
are used for higher power and bridged applications. 12 Gauge Twist-Lok speaker cables are an indus-
try standard for high powered connections. Turn the amp off before connecting your speakers.
14. TWIST-LOCK & BINDING POSTS SPEAKER OUTPUTS
Use the rear BINDING POSTS or TWIST-LOCKS as an alternate high powered connection. Wire sizes up to 7
gauge (50 amps) can be inserted into the binding post “side holes”. Larger cable can be used with “banana”
plugs which plug into the end of the binding posts (remove red caps). Binding posts are spaced on ISO stan-
dards. Use the two center RED binding posts for BRIDGE speaker connections (see 15 BRIDGE MODE). Use
12 GA cable for Twist-Lock connection. Insert cable and twist to lock into place. Use center Twist-Lock con-
nectorforBRIDGINGspeakerconnections.NOTE:REMEMBERTOPUSHIN“BRIDGE”BUTTONWHEN
