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 pro-
DCM1015
The DCM1015 professional dual 15 band graphic EQ amp is designed utilizing
Carvin’s 37 years of experience in power amp & equalizer technology. The
DCM1015 is Ideal for monitor set-ups because of its powerful equalizers which fea-
ure precise 2/3 octave filters. The primary advantage for the DCM1015 is its small
t
size, light weight, and high power that only requires two rack spaces. The thick
steel face plates, large recessed knobs, and heavy-duty steel chassis reflect the manufacturing quality within. All models carry the CE approval for world-wide use.
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, including 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
oroids deliver massive amounts of “on demand” current for continuous 2 ohm
T
operation. This gives the power supply a solid foundation, yielding more headroom 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.
DISTOR
TION-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 limiter 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 expensive, 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 allowing you to see your settings at a glance. Balanced TRS & XLR input connectors
are used to eliminate hum & noise. Speaker outputs 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.
