Line-Output To Shaker Amp
Unbalanced connection (jack 1/4“) for an amplifier to control a bass
shaker. Nominal working level 0 dB. The added signals of channel 1
and 2 and the add-on signals of the Aux Input are at this output (after
the gain control and before the earphone amplifier). No matter of the
adjusted earphone volume level, the shaker output can be switched
from full range to low pass with a cutoff frequency of 80Hz/24 dB/oct.

Switch Shaker-Amp Line Out
When the switch is pressed, the signal at the Shaker Amp Line Out
passes a low pass with a cutoff frequency of 80 Hz / 24 dB-octave. This
feature is very helpful when using a standard PA amplifier without
integrated frequency crossover for the shaker. The cutoff frequency of
80 Hz corresponds to the optimum working level of the bass shakers.
When the switch is not pressed, the signal is output full range. This is
also the correct switch position when operating the Fischer Amps
Shaker Amp or the ButtKicker Amplifier BKA 1000-4 in combination with
the Fischer Amps In Ear Amp 2, as these units have an integrated,
controllable low pass.

Ground Lift Button
Separates the audio ground from the system and cabinet ground. When
there is a ground loop when connecting various appliances, pressing
the Ground Lift button can solve the problem. (The cabinet of the In Ear
Amp 2 is still connected with the protective ground of the power supply)

Input Voltage Select
115V /230V
Switch to adjust the appliance to the country’s supply voltage 230V AC
or 115V AC. Before switchover, always switch off the appliance and
disconnect the mains cable from the operating voltage. Doing so
prevents overload of the internal PSU. It is not necessary to replace a
fuse in the appliance for adjusting the operating current.

Power In Jack
3-pole Euro mains socket to connect the provided 3-pole Euro power
cable. To supply the appliance with voltage, connect it to a grounded
power outlet. The metal casing of the appliance is permanently
connected to the internal ground wire. The self-resetting fuses are all
inside the appliance and do not have to be replaced in case of fault, but
reset after trouble-shooting. If the power cable is damaged, replace it by
a new, reliable cable immediately.
