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 or allowing any other foreign matter inside the unit. Thepanelofyourunitcan
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 HT760M professional Dual Graphic Monitor amps were designed utilizing
Carvin’s33years ofexperienceinpoweramp &equalizertechnology.The HT760M
isIdeal for monitor set-ups becauseits small size, light weight, highpower, and
EQ capabilities allow you to use only one piece of gear in place of two or three.
Thissavesyou work, rack space, andmoney. Theirthick brushed anodized alu-

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 HT Series amps deliver
flat, transparent, unaltered sound—especially important to the studio user. And

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 chassis is made from heavy-duty 16 gauge steel thatisgalvanizedbefore
being painted to prevent rust. All internal cabling is neatly tied and harnessed.
Every circuit card is MIL SPEC, double-sided, through-holeplated, fire retardant
FR-4glassepoxy. This insuresthat thesolderflowsonthe top,bottomandthrough
each hole of every component, preventing components from shaking loose—
even through constant tour use. Neutrik™ XLR connectors, heavy-duty power
switches, recessed knobs, machined aluminum front panels and extruded han-
dlesallgivetheHTamps a “tank-like” ability to handle rough, touring transport.
TOTALLY MODULAR
With the HT 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-
solder anything. This applies to every aspect of the HT Series amps including
thepower supply,power cards, heat sinks and fans. Everything is connected by
heavy-duty AMP™ and MOLEX™ type connectors for easy replacement—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. ThismeansthattheHTSeriesarethermally“over-engineered”tobesure

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

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
welldesigned limitercanincrease youramp’saverageoutput asmuchas 3db. 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 dis-
tortion, the HT Series limiters keep your sound pure and uncolored!
FRONT PANEL & CONNECTING UP
TheHT760Mfeaturesfrontpanelsignal,peakandprotectLEDs which let you mon-
itor the status of the amp easily. Also, both channels use precision 41 detent level
controls allowing you to see your settings at a glance. The main features are the two

CARVIN ENGINEERING DATA OPERATING MANUAL
HT760M EQUALIZED MONITOR POWER AMP

FRONT PANEL
1. MOUNTING
Sturdy one piece aluminum handles make for easy transporting along with facilitating rack installation.
Therackmounting holesare designedonISO standardspacing. Four 10-32 x.5” phillipmachinescrews
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. TheredLED unmistakablyindicatesthat all circuitsareproperlypowered up. Yellowwaschosen
so the operator could see the other indicators 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 full
powerwithoutreducingthe headroom ofthesignalsource,thelevelcontrols shouldbeturnedupapprox-
imately 1/3 (15 on the dial).
4. DUAL 9-BAND GRAPHIC EQUALIZERS
Controlingfeed-back in a monitor system andfine tuning your sound are easywith the HT760M’s two
on-board EQ’s. For feed-back, find the offending frequency (usually in the upper bands) and push the
slider down to cut the level of 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. The slid-
ers are designed to move hard so adjustments will stay in place.
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. 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);
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 or speaker system. Reset this condition byturning the ampoff for twoseconds and
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 is 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) Intake air is extremely
warm,c)Frontexhaust vents restricted,ord)Excessive speakerload(tryotherspeakersor 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
7. COOLING FAN
The fan is designed to pull air in to the amplifier. Do not restrict or block its intake or the amp will go
into protect mode. Hot air entering the amp may also cause the amp to go into protect mode.
8. XLR CHANNEL INPUTS
Formost professional applications,use the XLR balanced inputs. Thiswill help to reducehum andallow
for longer cable runs from your signal source (mixer, etc). Because this is a balanced input, the gain will
be6dBhigherthanusingthe1/4” input jackwithnonbalancedlines. XLRpinconfiguration:Pin 1: 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 both channelsfrom either input. All signalsentering any
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
thatresult in audible hum. The input(1/4” & XLR) GROUND LIFTswitch on the rear panel will help elim-
inate this problem. If not, another way to eliminate ground loops is to install a “line matching” trans-
former between the amplifier input and the signal source.
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 most applications. Turn the amp off before connecting
your speakers.
14. SPEAKER BINDING POSTS
For heavy-duty 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

ishandledby channel 1.Channel2 isnon-operational. Theminimum speaker impedanceis4 ohmsora 25V
distributionline. CAUTION: Thepower developed bybridgingyour ampcandestroymostspeakersystems!
16. AC POWER
Your amp is designed to run on either 120V 60 Hz or 230V 50Hz depending on the model purchased.
Thevoltage range for 120V modelis 95V to 132V andfor 230V model it is 195V to 253V. The rear heavy-
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 you with the convenience of a circuit breaker so that you will never have to replace
a 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.
