OUTPUT
A IEC MAINS SOCKET - Accepts standard 50/60 Hz AC mains voltage. Check that the
voltage indicated on the back is the same mains voltage as your country.
B FUSE HOLDER - To remove the fuse, push and turn the fuse holder cap. Use a 1 Amp
SLO-BLO fuse. Always replace fuse with same value and type.
C GROUND TERMINALS - Use these to minimise hum. See troubleshooting section.
Normally these two terminals are joined by a "ground" strap. Moving this strap is similar to
disconnecting the AC mains 3rd pin ground but includes the chassis/rack ground. You can
also connect a wire from the "circuit ground" to your console in some situations. Experiment.
D XLR BALANCED OUTPUT - This is a transformer balanced output which will drive any
impedance down to 600 ohms, but an impedance of 2000 ohms or greater is preferred. Pin
out is as follows: PIN1 = Ground, PIN2 = high (+), PIN3 = low (-).
E 1/4" UNBALANCED OUTPUT - The 1/4" output is a transformerless output and
disconnects the transformer & XLR output when a plug is inserted. Tip = Signal, Sleeve =
Ground, Ring = unused. Use either output but not both
F GAIN SET PRESET - This control adjusts the feedback over the line amplifier. It is preset
for unity gain, however, additional gain is available through this screwdriver adjust control.
G 1/4" UNBALANCED INPUT - 3000 ohm input impedance, unbalanced. It is meant as an
input that bypasses the transformer. This is too low as a "direct" for guitars but can be great
with an effects pedal or preamp between the guitar and EQ. You may need the gain these
pedals often provide. Most synths can drive this input but also may be low level.
H PHASE REVERSE - Switched in the UP position will retain the floating input signal in
phase. Switched in the DOWN position will reverse the phase of the floating input signal.
Switched in the MIDDLE position switches off the transformer and the high impedance
unbalanced 1/4" input is optimised. The 1/4" input is always on but not highest impedance
(3K) until the switch is in the middle position. The middle position kills the XLR in.
I XLR BALANCED INPUT - Fully floating / balanced input. Input impedance is 5000
ohms. Pin out is as follows: PIN1 = ground, PIN2 = positive going phase (+), PIN3 =
negative going phase (-). The PHASE switch must be on the "0" or "180" position.
