User manual CARVIN DCM2000

[. . . ] CARVIN ENGINEERING DATA DCM2000, DCM2500 & DCM2570 POWER AMPS OPERATING MANUAL 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. In the event you have to re-ship your unit, always use the original carton and packing material. CARVIN and the shipping company are not liable for any damage caused by improper packing. [. . . ] The built-in "optio" limiters are recommended to hold down peaks that could cause early distortion. This will help to raise the average power so that you can get more output from each channel. To check the effectiveness of the limiters when the channel starts to distort (under full output), engage the limiters and hear the reduction of the distortion. If the distortion stops, you can try to turn the channel up for more power. WARNING: Do not check in an environment where the sound level could damage your ears! 12. CHANNEL SIGNAL INDICATOR The green SIGNAL LED indicators will start to flash when there is a signal passing to your speakers (-30dBµ). This lets you know when the amp is passing a signal to your speaker connectors. 5. CHANNEL CLIP INDICATOR The red CLIP LED indicators will start to flash when each channel has reached its maximum output. However, consistent flashing caused from higher frequencies may damage high frequency drivers (excessive distortion). SPEAKER 1/4" AND SPEAKONTM OUTPUTS The standard 1/4" SPEAKER jacks are offered for low power applications. COOLING VENTS/FAN Upon rack installation, the rear of the amp must be fully exposed to room temperature air. The surrounding air should not be warmer than 120°F or the thermal protection could activate the PROTECT LED. The front cooling vents are not to be restricted from exhausting the warm air. 14. BINDING POST OUTPUTS For other high power speaker connections, use the rear BINDING POSTS to connect your speakers. Wire sizes up to 7 gauge (50 amps) can be inserted into the binding post "side holes". Larger cable can be used with "banana" plugs which plug into the end of the binding posts (remove colored caps from the top of the binding post). Use the two center RED binding posts to BRIDGE both power amps (see 15 BRIDGE MODE). 7. PROTECT LED INDICATOR The red PROTECT LED provides the operator with information about the status of the amplifier. The PROTECT LED can come on under 3 different conditions (when this happens both channels are muted by disconnecting the output speaker relays protecting your speakers); 1) During power-up, the amplifier stays in a muted state for approx. 3 sec until it determines that everything is functioning normally (no output shorts or over temp conditions). 2) When the output load draws excessive current or a direct short is detected caused by a shorted speaker cable or speaker system, the RED PROTECT LED will illuminate. Reset this condition by turning the amp off for two seconds and then on again. [. . . ] 6) DEDICATED CIRCUIT BREAKER: Each amp will require a dedicated circuit breaker for its full output. There will be a sustained loss of power if the AC voltage falls below the rated 120V or 230/240V input. 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 3 YEARS unless otherwise stated. Carvin will service and supply all parts at no charge to the customer providing the unit is under warranty. Carvin assumes no responsibility for horn drivers or speakers damaged by this unit. [. . . ]
