1 C1LO CH1 Gain-Control Input Low. Positive voltage reduces CH1 gain. 2 A1HI CH1 Signal Input High. Positive voltage increases CH1 output. 3 A1LO CH1 Signal Input Low. Usually connected to CH1 input ground. 4 GAT1 CH1 Gating Input. A logic high shuts off the CH1 signal path. 5 GAT2 CH2 Gating Input. A logic high shuts off the CH2 signal path. 6 A2LO CH2 Signal Input Low. Usually connected to CH2 input ground. 7 A2HI CH2 Signal Input High. Positive voltage increases CH2 output. 8 C2LO CH2 Gain-Control Input Low. Positive voltage reduces CH2 gain. 9 C2HI CH2 Gain-Control Input High. Positive voltage increases CH2 gain. 10 A2CM CH2 Common. Usually connected to CH2 output ground. 11 A2OP CH2 Output. 12 VNEG Negative Supply for Both Amplifiers. 13 VPOS Positive Supply for Both Amplifiers. 14 A1OP CH1 Output. 15 A1CM CH1 Common. Usually connected to CH1 output ground. 16 C1HI CH1 Gain-Control Input High. Positive voltage increases CH1 gain. Rev.
