CARVIN ENGINEERING DATA

DCM1500 & DCM2000 POWER AMPS OPERATING MANUAL

DCM1500, DCM2000

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 replace- ment—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.

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 protection 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

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.
