The AEQ OP-60 auxiliary stereo + mono sum output module carries
out the function of summing all signal inputs assigned to its bus.
The output level is
controlled by means of the fader (1).
This module delivers the mono output signal on the connector (2),
as well as the stereo output signal on the connectors (3) (left channel) and (4) (right
channel).
By way of the internal programming jumpers, it is possible
to turn a OP-60 module into a OP-40 module.
