Matching the gains of mulitiple amplifiers. This procedure requires the CC-1 to be placed in a special mode reserved for SPL competitors and audiophiles. 1. Switch the CC-1 off by holding the OFF button for 1 second. (This must be done to initalize the program mode) Now switch CC-1 power on by pressing the ON button. 2. Disconnect the harness to make sure there is no signal being applied to the CC-1 and that the Signal LED is NOT illuminated. 3. Press and hold the READ button for 3-5 seconds or until the Set LEDs start flashing. Release Set button. CC-1 is now in competition mode!! 4. Next you need to connect the CC-1 to the “Master” amplifier’s outputs. Use the included harness to connect to amplifier’s outputs; Red to speaker (+) and Black to battery ground. 12 5. Set the source unit’s volume to zero. Select the track on the CD that corresponds to the desired frequency you wish to match gains at. If you don’t know which frequency to use try 40 Hz (track 10 Disc A) if it is a subwoofer amplifier, or 1 kHz (track 8 Disc if it is a full range amplifier. Play track on repeat. 6. Continue by turning up the source unit volume until you see the Signal LED illuminate green. If the LED turns red, this indicates the volume is too high. Turn volume down until LED remains green. 7. When Signal LED remains Green, press the READ button. The Blue Calibrated LED should illuminate. 8. Now without touching any adjustments on anything, connect the CC-1 to the output of the next amplifier that you wish to match it’s gain to the first amplifier. 9. The LEDs will indicate if the gain is too high or too low compared to the “Master” amplifier. 10. Adjust gain on the amplifier that the CC-1 is now connected to until the Calibrated LED illuminates. The amplifier’s gain is now matched to the Master amplifier’s gain within +/- 0.05dB !! 11. Repeat steps 9 – 11 for any other amplifiers in the system.
