Wrong type of screw could strip the threads; too long screw could touch and short the
internal circuit, cause permanent damages to the product and void the warranty.
Control options:
The product has two
recessed gain pots on the front panel,
one loudness control dip switch recessed
on the bottom of the unit, and a remote
volume control port on the rear panel.
The Line Gain pot controls the mixed 3

remove the overall cable jacket, separate the individual wires, strip off the wire insulation precisely 3/16”

unbalanced wiring, remember to use short jumper to connect pin 2 and 5 to pin 3 (ground the unused “-
