CARVIN ENGINEERING DATA OPERATING MANUAL
The DCM Series professional amps are designed utilizing Carvin’s 35
years of experience in power amp technology. They meet or exceed every
standard for professional amplification. Their powder coated steel face
plates, large recessed knobs and heavy-duty steel chassis reflect the manufacturing quality within. The DCM professional amps are available in
five different models and 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 of 50v/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 DCM 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 systems. 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 plated before
being painted to prevent rust. All internal cabling is neatly tied and harnessed.
Every circuit card is FR-4 MILITARY SPEC, double-sided, through-hole plated,
fire retardant 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. XLR connectors, heavy-duty power
switches, recessed knobs and machined front panels 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-solder anything. This applies to every aspect of the DCM 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 DCM 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. A high efficiency,
multi-speed fan cools your amp quietly even when moving air at up to 115 CFM!
LIGHTER WEIGHT
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 reducing stray magnetic fields eliminating hum & noise. This is especially important for the recording industry.

DCM1500 & DCM2000 POWER AMPS
DISTORTION-FREE LIMITERS
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 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
monitor the status of the amp. Balanced XLR input and through jacks are used to
eliminate hum & noise. Speaker outputs features Twist-Lok connectors, plus 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 multiple amp systems. The accessory group also features a recessed bridge
mode switch for delivering full power into a 4Ω load or 70V distribution system
and a limiter ON/OFF switch that gives you the choice of using the internal limiter
circuitry.
