1. Main AC connector with fuse. 2. Amplifier outputs - connect to the power amplifier speaker outputs corresponding to Ls, Rs, Bsl, Bsr and Sw channels. 3. Amplifier outputs - connect to the power amplifier speaker outputs corresponding to Lh, Ll, Ch, Cl and Rh, Rl. 4. Amplifier level - this trimpot adjusts the level of the input lines coming from the Power Amplifiers. 5. HD-15 connector - connect to Ls/Rs amplifier
.
6. HD-15 connector - connect to Bsl/Bsr amplifier
.
7. Processor level - this trimpot adjusts the level of the input lines coming from the processor
.
8. Crossover outputs - connect to the power amplifier inputs corresponding to Ls, Rs, Bsl and Bsr
.
9. HD-15 connector - connect to Rl/Rh amplifier
.
10. HD-15 connector - connect to Sw amplifier
.
11. Crossover outputs - connect to the power amplifier inputs corresponding to Rl, Rh and Sw
.
12. HD-15 connector - connect to Ll/Lh amplifier
.
13. HD-15 connector - connect to Cl/Ch amplifier
.
14. Crossover outputs - connect to the power amplifier inputs corresponding to Ll/Lh and Cl/Ch amplifier
.
15. Optional input - connect these to the EX outputs of the processor 16. Bargraph level - this trimpot adjusts the sensitivity of the front panel VU Bargraph. 17. Main input - connect this to the main outputs of the processor
.
18. AC Emergency power input - 12-16V
AC, 0.5A
19. EX Selector switch - without EX, turn on 1-4 switches. With EX, turn on 5-8 switches. This routes the correct Ls/Rs inputs to the CM-680 circuitry
