The HT760M professional Dual Graphic Monitor amps were designed utilizing
Carvin’s 33 years of experience in power amp & equalizer technology. The HT760M
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. Their thick brushed anodized alu-
minum face plates, large recessed knobs, quality metal sliders with rubber boots,
and heavy-duty steel chassis 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 insure
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. High frequencies are transparent and open—even at extreme levels. Linear
feedback circuits reduce distortion to near the theoretical zero limit, preventing any
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
you can drive any type of reactive loads, including 70V transformer distribution sys-
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 that is galvanized before
being painted to prevent rust. All internal cabling is neatly tied and harnessed.
Every circuit card is MIL SPEC, double-sided, through-hole plated, fire retardant
FR-4 glass epoxy. This insures that the solder flows on the top, bottom and through
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-
dles all give the HT amps 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
the power 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. This means that the HT Series are thermally “over-engineered” to be sure
heat will never be a concern. Even outdoor concerts in direct sunlight will not cause
thermal shut down. Carvin uses precision 6063 T-5 aluminum high ratio heat sinks
that are extruded for massive amounts of cooling. High efficiency, multi-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
power supply a solid foundation, yielding more headroom for the largest subwoofer
application. Not only do toroids deliver high current, but they are known for reduc-
ing stray magnetic fields eliminating hum & noise. This is especially important for
the recording industry.

RECEIVING INSPECTION—read before getting started
INSPECT YOUR UNIT FOR ANY DAMAGE which may have occurred during shipping. If any
damage is found, please notify the shipping company and CARVIN immediately.
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 possible protec-
tion 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.
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
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 dis-
tortion, the HT Series limiters keep your sound pure and uncolored!
FRONT PANEL & CONNECTING UP
The HT760M features front panel signal, peak and protect LEDs 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
9-Band graphic equalizers that easily allow fine tuning of your sound or balancing out
and elimitaing feedback on a monitor system. Balanced 1/4 phone & XLR input jacks
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
both channels together eliminating Y connectors and allowing amp patching in mul-
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.
