Carvin ac 120 s owners manual

PLUGGING IN: To prevent speaker pops and other surges, it is important to have your equipment power on in the correct order. The order is fairly simple to understand, because it is the same order that audio signals pass through your system. Most importantly, turn power amps ON last, and turn them OFF first. This will prevent the power amps from amplifying pops and possibly damaging your speakers. The AC120S will turn ON the rear outlets in order from 1to 10, and will turn them OFF in reverse order from 10to 1. Plug in each unit in order of the audio signal path, beginning with the right rear outlet (the outlet labeled 1 in the image on the front page), which is furthest from the AC cord. Example: 1. Wireless mic receivers or mic preamp units. 2. The mixer. 3. Compressors/processors in the mic inserts. 4. Effect processors in the effect loops of the mixer. 5. EQs or compressor/limiters between the mixer and amps. 6. Electronic crossovers or speaker management controllers. 7. Power amps. Power amps are always powered ON LAST and OFF FIRST. *NOTE: The maximum total current available to the all ten outlets is 20 AMPS. A maximum of one high powered amplifier can be plugged into the AC120S(such a DCM1000 or larger). CHECKING YOUR SETUP: Now that you have your gear plugged into the AC120Sin the proper order, press IN the POWERswitch. The LINE VOLTAGEmeter should display a number from about 110 to 120 volts. If the voltage is too high or too low, your equipment may become damaged or not turn on. Consult your owners manuals for acceptable ranges. Turn all gear plugged into the AC120Sto their ON positions. (Once your setup is complete, you can leave the switches for this gear in the ON position, and use the AC120Sfor off/on.) If you are using any amplifiers not plugged in to the AC120S, turn them ON LAST, after the power ON sequence is finished. (These amps should also be shut OFF FIRST, before starting the power OFF sequence.) Make sure that your power amps are set to a low volume but not off, so you can hear pops if they happen but are least likely to damage gear. TEST: To test the order of your plugs, press the 1 button on the front panel. The white LED just above the 1 should light up. (see item #8 MANUAL POWERbuttons, on front page). Continue with buttons 2to 10, and notice if any pops are heard. If a loud pop is heard when pressing a certain button, you may need to change the order of your plugs. Now turn each outlet OFF, in reverse order 10to 1, listening for pops and re-arrange the order if necessary. POWERING UP: Press the SEQbutton on the front panel. The LEDs 1thru 10on the front panel will start coming on. If there are any loud pops coming out of your system at any time during the sequence, you may need to increase the TIMEsetting, or change the order of your AC plugs on the rear of the AC120S. POWER OFF: First, turn off any amps in the signal path not plugged into the AC120S. Press the SEQbutton again to begin the POWER OFF sequence. The LEDs will begin to turn off in reverse order, 10thru 1. Again, if there are any loud pops coming out of your system at any time during the sequence, you may need to increase the TIMEsetting, or change the order of your AC plugs. To shut off power during the sequence on or sequence off period, turn off the main POWERswitch on the front panel. RISK OF ELECTRIC SHOCK DO NOT OPEN IMPORTANT!
