Gain Boost
A recessed switch on the rear panel allows the HI Z input to be boosted by 26dB, useful
for instruments with weak pickups or where more overdrive is required. When the XLR
is being used or for normal line level signals (like keyboards)——make sure the switch is in
the OUT position.

Hi Z input
The only difference between mono inputs 1-2 and 3-4 is
the Hi Z inputs for guitars or other instruments.
Standard 1/4”" (6.25mm) Jack socket for unbalanced line
level signals or instrument pickups. Wired Tip=Hot(+),
Ring=cold (-), Sleeve=Chassis.
The Hi Z input connects to the XLR input through a cir-
cuit, so be aware that the two signals will add together if
both inputs are plugged in simultaneously.
The Hi Z input can be used with normal line level signals
but is designed specifically to match signals from instrument
pickups. The input impedance is extremely high (10Mohms)
and a FET (Field Effect Transistor) running in Class A mode
emulates the type of circuits used in valve guitar combos or
head amplifiers. The input circuit has soft asymmetric over-
drive characteristics, giving a warm 2nd harmonic character
to the sound if required.
