| This simple module, which is used in both the |
| 6-channel and 12-channel mixers, monitors the input level of each channel. It consists of four identical 5-LED bargraph driver circuits. The components associated with the two ICs determine the attack and decay times, and the bandwidth. Each of the four bargraph displays is made from three green, one orange and one red LED. |
