User manual CARVIN DCM1001

[. . . ] This symbol is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN This symbol is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. LIMITED WARRANTY Your Carvin product is guaranteed against failure for ONE YEAR unless otherwise stated. Carvin will service and supply all parts at no charge to the customer providing the unit is under warranty. Shipping costs are the responsibility of the customer. CARVIN DOES NOT PAY FOR PARTS OR SERVICING OTHER THAN OUR OWN. [. . . ] 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. Heavy-duty XLR connectors, power switches, recessed knobs, steel front panels all 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 AMPTM and MOLEXTM 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. High efficiency, multispeed 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 reducing stray magnetic fields eliminating hum & noise. This is especially important for the recording industry. 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). [. . . ] No other speaker connectors or binding posts can to be used at the same time!". The INPUT and LEVEL is handled by channel 1. The minimum speaker impedance is 4 ohms or a 25V distribution line. CAUTION: The power developed by bridging your amp can destroy most speaker systems! [. . . ]
