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
