Actuators and Connections Front Side
Description of the actuators (front side) :
(1)
On/Off Switch
The operating voltage of the Amp is switched off on the mains side.
When switched off, the Amp needs no power from the mains.
(2)
Control-LED
After switching on the Amp, the LED below the off/off power switch
illuminates red for approx. 3 seconds and then changes to green. IN
case of a defect inside the Amp or in case of overload, the internal relay
cuts off the headphone output from the electronics and the LED
illuminates red. If the LED does not change to green after switching on
the Amp, there is an overload or the Amp is defective.
(3)
LED level indicator
Indicates the internal working level with two duo-LEDs (one each for left
and right). Green indicates an input level of -15dB to +2dB, the red LED
is illuminated when the level is +2.5dB or higher. Adjust the signal
source (mixing console) so that there is a level of approx. 0dB at the
output. With signal peaks, the red LEDs should flare up slightly. This
guarantees a correct operating level of the limiter for instance with
sudden level changes.

Earphones Outputs
Eight 3-pole, XLR male headphone/earphone jacks to connect a 3-pole
standard microphone line in combination with the Fischer Amps Mini
Body Pack XLR. With standard microphone cables, up to eight
musicians can be supplied with the stereo signal of the In Ear Amp 8.
The headphone signal can also be transmitted by a multicore or sub-
multicore without needing an adaptor. The eight outputs are connected
internally to a powerful headphone amplifier and all have the same
output level. The artists can adjust their individual volume at the passive
volume control of the Mini Body Pack. Position “Low” of the output level
switch at the rear side of the unit allows headphone impedances from
12 to 40 ohms per output. Position “High” of the output level switch
allows headphone impedances > 40 ohms. The XLR output connectors
have following assignment: Pin 1 = Ground, Pin 2 = signal left, Pin 3 =
signal right.
