User manual CARVIN DCM150

[. . . ] CARVIN ENGINEERING DATA DCM150 POWER AMP OPERATING MANUAL The DCM150 professional amp is designed utilizing Carvin's years of experience in power amp technology. It meets and exceeds every standard for professional amplification. The thick brushed anodized aluminum face plate, large recessed knobs and heavy-duty aluminum chassis reflect the manufacturing quality within. The DCM150 "High Energy Transfer" amp carrys the CE approval for world-wide use. [. . . ] Use the two center RED binding posts for BRIDGE speaker connections (see 11 BRIDGE MODE). 11. BRIDGE MODE--70V DISTRIBUTION SYSTEMS The green SIGNAL LED indicators will start to flash when there is a signal passing to your speakers (-30dBM). This lets you know when the amp is passing a signal to your speakers. 5. CHANNEL CLIP INDICATOR The red CLIP LED indicators will start to flash when each channel has reached its maximum output. Occasional flashing caused by lower bass frequencies is OK. However, consistent flashing caused from higher frequencies may damage high frequency drivers (excessive distortion). This does not cause damage to the amp. 6. EQ EXPAND SWITCH The DCM150 can be operated in bridge mode if you require a 70V distribution speaker system or a high powered mono (single channel) amp. With your amp off, push in the rear BRIDGE switch after you have made your speaker connections to the rear center RED binding posts (ch 1 is + and ch 2 is -). No other speaker jack or binding post can to be used at the same time!". The INPUT and LEVEL is handled by channel 1. The minimum speaker impedance is 8 ohms. CAUTION: The power developed by bridging your amp can destroy speakers! 12. PARALLEL OR "Y" INPUTS When set to the `in' position this circuit will cut the mids by -4dB at 1KHz. This works well as a loudness contour when operating at low volume levels or adds tone when using it in a bass or guitar rack. When set to the `out' position it provides a flat, normal response. Try it both ways and set as desired. The rear PARALLEL switch allows you to drive both channels from either input. All signals entering any input will be available on both channels. This feature is used to "daisy chain" one piece of equipment to another. Just plug into the unused INPUT (1/4" or XLR) and it will become an output for other equipment. 13. XLR CHANNEL INPUTS For most professional applications, use the XLR balanced input. This will help to reduce hum and allow of longer cable runs from your signal source (mixer, etc).
