CARVIN DCM1000 User manual

CARVIN ENGINEERING DATA OPERATING MANUAL
The DCM Series professional amps are designed utilizing Carvin’s 35
yearsofexperienceinpoweramptechnology.Theymeetorexceedevery
standard for professional amplification. Their thick brushed anodized
aluminumface plates,large recessedknobs andheavy-duty steelchas-
sis reflect the manufacturing quality within. All models carry the CE
approval for world-wide use.
PURE—TRANSPARENT SOUND
Carvin considers the sound of an amp equally important as its reliability. To
insurepure,uncoloredsound,wedesignedoneofthefastestrespondingpower
amps on the market today. High slew rates of 45v/µs deliver superb transient
response. High frequencies are transparent and open—even at extreme levels.
Linear feedback circuits reduce distortion to near the theoretical zero limit, pre-
venting any type of harshness which would lead to ear fatigue. The DCM Series
ampsdeliverflat,transparent,unalteredsound—especiallyimportanttothestudio
user. And you can drive any type of reactive loads, including 70V transformer
distributionsystems. These amps aredesigned to deliver non-stop,continuous
power and are completely protected from heat and short circuits.
ULTRA RUGGED FOR TOURING
Every chassis is made from heavy-duty 16 gauge steel that is plated before
beingpaintedtopreventrust. Allinternalcablingisneatly tiedandharnessed.
EverycircuitcardisFR-4MILITARYSPEC,double-sided,through-hole plated,
fireretardantglassepoxy. Thisinsuresthatthe solderflowsonthetop,bottom
andthrougheachholeofeverycomponent,preventingcomponentsfrom shak-
ing loose—even through constant tour use. Neutrik™ XLR connectors,
heavy-duty power switches, recessed knobs, 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
everneedanI/O(input/output)connectorcardbecauseaconnector wore-out,
just unplug it and re-install the replacement card in minutes. You don’t have
to de-solder anything. This applies to every aspect of the DCM Series amps
including the power supply, power cards, heat sinks and fans. Everything is
connectedbyheavy-dutyAMP™andMOLEX™typeconnectorsfor easyreplace-
ment—even the Toroid transformer is a total plug-in.
HEAVY-DUTY COOLING
Carvin offers up to30%morecoolingthancomparableampsratedatthesame

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 iso-
lators”. UnlikeampsthatuseFETcontrolledlimiterswhich caninjectsmallamounts
of distortion, the DCM Series limiters keep your sound pure and uncolored!
FRONT PANELS & CONNECTING UP
The DCM Series feature front panel signal, peak and protect LEDs which let you
monitorthe status oftheamp. Both channels useprecision 41 detentlevelcontrols
allowingyoutoseeyoursettings ataglance. Balanced1/4phone& XLRinputjacks
are used to eliminate hum & noise. Speaker outputs feature 1/4” jacks & heavy-
duty binding posts that accept up to 50 amp #7 speaker wires.
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
bothchannelstogethereliminatingYconnectorsandallowingamp patchinginmul-
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.

FRONT PANEL
1. MOUNTING
Sturdy one piece 12 guage steel face plate accomodates easy transporting along with facilitating rack
installation. The rack mounting 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 was
chosen so the operator could see the red indicators (clipping or protect) from a distance.
3. CHANNEL LEVEL CONTROL
A precision 41 step input LEVEL attenuate is used to adjust the volume levels. To deliver the amps maxi-
mumpower withoutreducingthe headroom ofthesignal source,the levelcontrolsshouldbe turnedfullon.
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.
6. FRONT COOLING VENTS/FAN
Upon rack installation, the rear of the amp must be fully exposed to room temperature air. The sur-
rounding air should not be warmer than 120° or the thermal protection could active the PROTECT LED.
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
speakercable orspeakersystem. Reset this conditionbyturning the ampofffor twosecondsand
then on again. Check for shorted cables and the total speaker system impedance connected to
each channel (2 ohms 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. 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 XLR balancedinputs. This will helptoreducehum andallow
of longer cable runs from your signal source (mixer, etc). Because this is a balanced input, the gain will
be6dB higher thanusingthe1/4”inputjackwithnon balanced lines. XLRpinconfiguration:Pin1:Grounded
through the GROUND LIFT switch, Pin 2: positive Bal. signal and Pin 3: negative Bal. signal.
9. CHANNEL 1/4” PHONE JACK INPUT
This stereo phone jack is designed to receive either balanced or unbalanced input signals. Balanced sig-
nals coming into this jack should be wired with the connector’s tip going to signal + and the connector’s
ring to signal -. The connector’s sleeve is then tied internally to ground through the GROUND LIFT switch.
10. PARALLEL OR “Y” INPUTS
Therear PARALLELswitch allows youto drive bothchannels from eitherinput. 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 then cutting the ground wire to PIN 1.
12. LIMITERS
ToactivatetheLIMITERS,engagetherearlimiterswitch. Thebuilt-inhighqualitylimitersarerecommended
to hold down peaks that could cause early distortion. Limiters will help to rise 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 the distortion stops, you can turn the channel up for more power. The lower bass frequencies are most
affected. 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. Turn the amp off before con-
necting your speakers.
14. SPEAKER BINDING POSTS
For high power speaker connections, use the rear BINDING POSTS to connect your speakers. Wire sizes up
to7gauge(50amps)canbeinsertedintothebindingpost“sideholes”. Largercablecanbeusedwith“banana”
plugs which plug into the end of the binding posts (remove colored caps). Binding posts are spaced on ISO
standards. Use the two center RED binding posts for BRIDGE speaker connections (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
orahighpoweredmono(singlechannel)amp. Withyourampoff,pushintherear(recessed)BRIDGEswitch
after you have made your speaker connections to the rear center RED binding posts (ch 1 is + and ch 2 is -
). No other speaker connectors or binding posts can to be used at the same time!”. The INPUT and LEVEL
ishandledbychannel1.Channel2isnon-operational. Theminimumspeakerimpedance is 4 ohms or a 25V
distributionline. CAUTION: Thepowerdevelopedbybridgingyourampcandestroymostspeakersystems!
16. AC POWER
Your amp is designed to run on either 120V 60 Hz or 230V 50Hz depending on the model purchased.
Thevoltage rangefor120V modelis95V to132Vand for230Vmodel itis195V to253V. The rearheavy-
duty AC receptacle will accept a standard grounded AC cord that is designed your country. Be sure to
check your power source before plugging into a grounded (3 prong) outlet. Never defeat the grounded
connection or electrocution may result! Firmly push the AC cord all the way into its recepticle.
17. AC CIRCUIT BREAKER
We have provided a circuit breaker so that you will never have to replace the fuse. Occasionally the
circuit breaker on your amp may have to be reset if high AC voltage surges are present or if the amp is
used with excessive loads. See “Helpful Hints”.
