Carvin DCM1000 Instruction Manual

CARVIN ENGINEERING DATA

OPERATING MANUAL

Pristine sound, brute power and no-fault reliability make the DCM amps the power

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, overheating is not a problem especially down at minimum impedances where

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

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 harshness

which would lead to ear fatigue.

The DCM deliver transparent, unaltered sound—

especially important to the studio user.

Drive any type of reactive loads, includ-

ing 70V transformer distribution systems.

ULTRA RUGGED FOR TOURING

Every chassis is made from heavy-duty 16 gauge steel that is plated before painted

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

hole of every component preventing components from shaking loose.

Speakon™

connectors, heavy-duty power switches, recessed knobs, all give the DCM amps

a “tank-like” ruggedness.

TOROID POWER SUPPLY

Toroids deliver massive amounts of “on demand” current for continuous

2 ohm

operation.

This gives the power supply a solid foundation, yielding more head-

room for large subwoofer applications.

Not only do toroids deliver 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.

Everything is connected by heavy-duty AMP™ and MOLEX™ type connectors

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

extra hot input signals (helps protect speakers).

In addition, a well designed lim-

iter can increase your amp’s average output as much as 3 dB allowing levels to

be turned up without peak distortion.

Part of Carvin’s design uses the more expen-

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!

FRONT PANELS & CONNECTING UP

The DCM Series feature front panel signal, peak and protect LEDs which let you

monitor the status of the amp.

Both channels use detente level controls allow-

ing you to see your settings at a glance.

Balanced TRS &

feature heavy-duty binding

posts,

Speakon™ connectors and 1/4” jacks.

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

together eliminating Y cables for patching multiple amp systems.

The accessory

group also features a BRIDGE MODE switch to deliver twice the power into a

“mono”

load or full power into a 70V distribution system, and a LIMITER ON/OFF switch

gives the choice of using the internal limiter circuitry.
