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 - 12-16VAC, 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.
