Genz Benz GBE 1200 Quick Reference Manual

EFFECTS LOOP JACKS — The serial "EFFECTS LOOP" jacks are
provided to allow access to the signal for the purpose of inserting signal
processing equipment such as compressors, chorus, delay & reverb
processors. Individual pre-EQ loops are provided for the TUBE channel
and the FET channel. An additional post EQ loop is provided for the
post-EQ summed (TUBE + FET) signal.
POWERFLEX SWITCH— This switch allows optimum matching of the
power supply to the speaker load. Similar in concept to output trans-
former matching in tube amplifiers, this feature allows the GBE-1200 to
drive 2 ohm loads at maximum efficiency compared to more traditional
designs. Driving 2 ohm speakers with the switch in the 4-8 ohm
position is not recommended as the amp's monitoring circuitry
may reduce the output power to minimize stress on the amplifier. .
An amber "2 ohm" indicator LED is provided on the front panel to con-
firm that the 2 ohm POWERFLEX™ mode has been selected.
XLR DIRECT OUT — Studio Quality, fully active transformerless bal-
anced DI. PRE/POST switch; GROUND switch; OUTPUT LEVEL Con-
trol adjustable between –50db and –10db. Fully protected from Phan-
tom Power.
FOOTSWITCH INPUT — The GBE 1200 is fitted with a 6 pin DIN jacks
for the 5 button footswitch (included). In order for the footswitch to func-
tion correctly, the amplifier's front panel switches for these functions
must be in the "out" position. This footswitch is unique to Genz Benz
due to the complex nature of it's functions and must be factory supplied.
This operates the CHANNEL SELECT, MIX, LF EXTEND, MID SCOOP
and HF ATTACK functions. The front panel switches over-ride all
footswitch functions.
SPEAKER OUTPUTS — The GBE 1200 features 2 SPEAKON
connectors. Minimum total load impedance is 2 ohms. The SPEAKON
is wired using pins 1+ and 1-, pins 2+ and 2– are not connected.
