1. Bypass Card XTB-680: 

When using external crossovers, the CM-680

must be equipped with a bypass card in the crossover slot. For connection

to a CP-650, slide dip switches D,E, & F on the XTB-680 to the “ON”

position. When using other electronic crossovers or speakers with passive

crossovers,  turn  DIP  switches  A,B  &  C  to  “ON”.  See  figure  #8

Connect crossover inputs to rear of CM-680 at Ll, Cl &Rl as per Fig.4

(Page9)
