The Rear Panel:
28: Footswitch. Connect the supplied two-button footswitch here for
remote on/off control of the internal reverb and chorus. (When con-
nected, the footswitch overrides the front panel chorus on/off
switch.)
Note: This is a STEREO jack: tip controls the chorus, ring controls the
reverb, sleeve is ground. Use only a footswitch equipped with a stereo
1/4” plug.
29: Effects Loop Send. When using an external signal processor, connect
this jack to the input of the effect by means of a shielded signal cable.
30: Effects Loop Return. When using an external signal processor, con-
nect this jack to the output of the effect by means of a shielded signal
cable.
31: High Z Balanced Line Output. Use this jack to connect a high imped-
ance, line level signal to a house sound board, a recording console or
an external power amplifier by means of an 1/4” stereo plug-termi-
nated cable. (Ring is signal +, tip is signal -, and sleeve is ground.)
32: Low Z Balanced Line Output. Use this jack to connect a low imped-
ance, line level signal to a house sound board, a recording console or
an external power amplifier by means of an XLR-terminated cable.
(Pin 1 is ground, pin 2 is signal +, and pin 3 is signal -.)
33: Gnd Lift. This switch, when depressed, electronically disconnects the
Low Z Balanced Output jack’s chassis ground connection. If you
experience excessive noise when using the Low Z Balanced Output
jack, depress this switch.
34: Line Output Level. Use this control to adjust the output level of the
line out signal. (This control works independently from the amplifi-
er’s master level control.)
35: Tweeter Level. Use this control to adust the signal output level from
the CA125D’s internal tweeter. Rotating this control counter-clock-
wise reduces the tweeter’s output level.
36: AC Line Cord. The grounded power cord should only be plugged
into a grounded power outlet that meets all applicable electrical
codes and is compatible with the voltage, power and frequency
requirements stated on the rear panel. Do not attempt to defeat the
safety ground connection!
