CARVIN ENGINEERING DATA OPERATING MANUAL
Pristinesound,brutepowerandno-faultreliabilitymaketheDCMampsthepower
amp of choice for pro audio. Massive Toroid power supplies with huge capaci-
tors deliver the bass that kick drums demand. Designed for continuous opera-
tion,overheatingisnotaproblemespeciallydownatminimumimpedanceswhere
other amps simply turn off.
Each DCM is hand built at our San Diego factory featuring all steel construction,
recessed controls and heavy-duty power components. The rock-solid, efficient
design with its superb testimonial-proven sound makes the USA built DCM an
amp you'll own for years.
PURE—TRANSPARENT SOUND
Carvin considers the sound of an amp equally important as to its reliability. To
insure pure, uncolored sound, we build one of the fastest power stages on the
markettoday. High slewratesof50v/µs deliversuperbtransientresponse. High
frequencies are transparent and open—even at extreme levels. Linear feedback
circuits reduce distortion to near the theoretical zero limit preventing harshness
whichwouldleadtoearfatigue. TheDCMdelivertransparent,unalteredsound—
especially important to the studio user. Drive any type of reactive loads, includ-
ing 70V transformer distribution systems.
ULTRA RUGGED FOR TOURING
Everychassisismadefromheavy-duty16gaugesteelthatisplatedbeforepainted
to prevent rust. All internal cabling is neatly tied and harnessed. Every circuit
card is FR-4 MILITARY SPEC, double-sided, fire retardant glass epoxy. Plated
through-holes insure that the solder flows on the top, bottom and through each
holeofeverycomponentpreventingcomponentsfromshakingloose. Speakon™
connectors,heavy-duty power switches,recessed knobs,all give theDCM amps
a “tank-like” ruggedness.
TOROID POWER SUPPLY
Toroidsdelivermassiveamountsof“ondemand”currentforcontinuous 2ohm
operation. This gives the power supply a solid foundation, yielding more head-
roomfor large subwoofer applications. Not only do toroidsdeliver high current,
but they are known for reducing stray magnetic fields eliminating hum & noise.
This is especially important to the recording industry.
MODULAR CONSTRUCTION
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 and re-install the replacement card. This applies to every aspect of
the DCM Series amps including the power supply, power cards, heat sinks and
fans. Everythingisconnectedbyheavy-dutyAMP™andMOLEX™typeconnectors
for easy replacement—even the Toroid transformer is a plug-in.
DISTORTION-FREE LIMITERS
The purpose of a limiter is to hold down peaks so the amp won’t distort with
extrahotinputsignals(helpsprotectspeakers). In addition, awelldesignedlim-
iter can increase your amp’s average output as much as 3 dB allowing levels to
beturnedupwithoutpeakdistortion. PartofCarvin’sdesignusesthemoreexpen-
sive, distortion-free linear “opto isolators”. Unlike amps that use FET controlled
limiters, which inject small amounts of distortion, the DCM Series limiters keep
your sound pure and uncolored!

1. MOUNTING
Sturdyonepiece12gaugesteelfaceplateaccomodatesstandard19”rackinstallation. Therackmount-
ing holes are designed on ISO standard spacing. Four 10-32 x .5” phillip machine screws are normally
used to secure the amp. Rear support brackets are not required.
2. POWER SWITCH
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.
3. CHANNEL LEVEL CONTROL
AprecisioninputLEVELattenuatorisusedtoadjustthevolumelevels. Todelivertheampsmaximumpower
without reducing the headroom of the signal source, the level controls should be turned full on.
4. CHANNEL SIGNAL INDICATOR
ThegreenSIGNALLEDindicatorswillstarttoflashwhenthereisasignalpassingtoyourspeakers(-30dBµ).
This lets you know when the amp is passing a signal to your 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.
6. COOLING VENTS/FAN
Upon rack installation, the rear of the amp must be fully exposed to room temperature air. The sur-
roundingair should not bewarmerthan120°Forthethermalprotectioncould activate the PROTECTLED.
The front cooling vents are not to be restricted from exhausting the warm air.
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) When the output load draws excessive current or a direct short is detected caused by a shorted
speaker cable or speaker system, the RED PROTECT LED will illuminate. Reset this condition by
turning the amp off for two seconds and then on again. Check for shorted cables and the total
speaker system impedance connected to each channel.
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.
Theamp will automatically reset within1to3minutes. ThePROTECTLEDwillturn off when ready.
Checkforthefollowingconditions; a)Therear intake air is restricted, b) Theintake 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). The minimum imped-
anceis 2ohms per ch or 4ohms BRIDGED. DCM2570minimum load is 4 ohmsper chor 8 ohms
BRIDGED.

8. CHANNEL INPUTS AND THROUGH
BalancedorUnbalanced1/4”TRSinputs canbeusedalong withthebalancedXLR’s. Themale“THROUGH”
XLRconnector carries the same signal as the female XLR to daisychainchannelsoradditionalamps. XLR
pin configuration: Pin 1: Grounded through the GROUND LIFT switch, Pin 2: positive Bal. signal and Pin
3: negative Bal. signal.
9. PARALLEL OR “Y” INPUTS
The rear PARALLEL switch “IN” allows you to drive both channels from either input in which a signal
entering any input will be available on both channels eliminating Y adapters.
10. INPUT GROUND LIFT
Many times sound systems are connected in such a manner to cause a grounded loop with the inputs
which 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 Carvin’s MTF55 “Ground Lifter”
betweentheamplifierinputandthesignalsource. ThisisolatestheinputgroundfromtheACpowerground.
11. LO CUT
(DCM2500, DCM2570)
The LO CUT switch inserts a 40Hz, 3rd order, high pass filter. This will remove sub audio frequencies
from damaging speakers and wasting inaudible power. It is active when the switch is pushed “IN”.
12. LIMITERS
To activate the LIMITERS, engage the rear limiter switch to the “IN” position. The built-in “optio” limiters
are recommended to hold down peaks that could cause early distortion. This will help to raise the average
powerso thatyou can getmore output fromeach channel. To check theeffectiveness of thelimiters when
thechannel starts todistort (under fulloutput), engage thelimitersand hear thereduction of thedistortion.
If the distortion stops, you can try to turn the channel up for more power. The lower bass frequencies are
mostaffected. WARNING: Donot check in an environment where the soundlevel could damage your ears!
13. SPEAKER 1/4” AND SPEAKON™ OUTPUTS
The standard 1/4” SPEAKER jacks are offered for low power applications. Speakon™ connectors are pro-
videdforhighpowerapplication. SecuretheSpeakon™connectionbyturningtotheright. ThecenterSpeakon™
is for Bridge only. Turn the amp off before connecting your speakers. DCM 2570 minimum load 4 ohms
14. BINDING POST OUTPUTS
For other high power speaker connections, use the rear BINDING POSTS to connect your speakers. 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 colored caps from the top of the
binding post). Binding posts are spaced on ISO standards. Use the two center RED binding posts to BRIDGE
both power amps (see 15 BRIDGE MODE).
15. BRIDGE MODE—25V/70V DISTRIBUTION SYSTEMS
The “DCM” Series can be operated in bridge mode if you require a 25V / 70V distribution speaker system
or a high powered mono (single channel) amp, which can double your power into a single load. With your
amp off, push “IN” the rear (recessed) BRIDGE switch after you have made your connections to either the
center bridge Speakon™ or the rear center RED binding posts (ch 1 is + and ch 2 is -). Select carefully or
damage may result to your speakers. This is why the switch has been recessed. No other speaker connec-
torsorbindingpostscantobeusedatthesametime! TheINPUTandLEVELishandledbychannel1.Channel
2 is non-operational. The minimum speaker impedance is 4 ohms. CAUTION: The power developed by
bridging your amp can destroy most speaker systems! DCM2570 minimum load is 8 ohms in BRIDGE
16. AC POWER
Your amp is designed to run on either 120V 60 Hz or 240V 50Hz depending on the model purchased.
The voltage range for 120V model is 95V to 132V and for 230V model it is 195V to 255V. The rear heavy-
duty AC receptacle will accept a standard grounded AC cord that is designed for your country. Be sure
tocheck your powersourcebeforeplugging into agrounded (3 prong)outlet.Never defeat thegrounded
connection or electrocution may result! Firmly push the power cord all the way into its recepticle. In the
case of a blown fuse; unplug the amp, remove the lid and replace the fuse located in the back corner
above where the AC cord connects to the circuit board.
FUSE: The fuse is located within the main chassis above the AC connector mounted on the rear, inside
the PC card. Normaly if the fuse fails, the amp will require service. See spec. chart for fuse values.
NOTE: Each amp will require a dedicated circuit if you are driving the amp to its full output. There will
beasustained loss of poweriftheAC voltage falls belowtherated120V or 230/240V. Useaheavygauge
power cable and power source.

HELPFUL HINTS
1) NO SOUND FROM CH 2: The rear (recessed) BRIDGE
switch has been inadvertently pushed in.
2) STEREO CHANNELS SOUND THE SAME: The rear
PARALLEL switch has been inadvertently pushed in.
3) NOHIGH FREQUENCIES: Tweeters ormidrangedrivers have
been damaged or blown from feedback or to much power.
4) SYSTEM HUM: Switch the rear GND LIFT switch IN or OUT. If
the hum is not eliminated, then install Carvin’s MTF55 “Ground
Lifter” between the amplifier input and signal source. This iso-
lates the input ground from the AC power ground.
5) POOR SOUND (BASS): The speaker systems are wired out
of phase to each other. To correct, reverse the wires on one
speaker connector only and your sound, especially the bass
response will improve.
