Change-over switch
Stereo/Mono-Mix
Stereo-Mode: The device outputs the signal fed into the left input (channel 1) at the
left earphone and the signal from the right (channel 2) at the right
earphone.
Mono Mix Mode: Channel 1 and channel 2 are mixed and output to both earphones. By
means of the pan (balance) control the ratio between both channels can
be adjusted.
If a stereo signal is connected at the Aux-Input, a Mono Mix signal is
generated automatically from this stereo signal when the switch is in
position Mono Mix.

Gain Control Adjusts the correct working level of inputs 1 and 2, the level can
Channel 1/2 be adjusted from 12dB to –10dB. The optimum working level is when
LEDs 0dB light with signal input, and when the red limiter LEDs flicker
slightly with signal peaks. This ensures correct working of the limiter,
which limits the sound level when it escalates, e. g. due to feedbacks.
(8)
LED Level Display Shows the internal working level before the earphone power amp with
Pan control and Stereo/Mono Mix changeover switch. The levels for
channels 1/2 and Aux Input at the gain control are set in such a way
that the 0dB LEDs light when there is a signal, and the red LEDs flicker
slightly when there are signal peaks. The red LEDs light from an internal
working level of +4dB on, at +5dB the internal working level is limited.
This ensures correct working of the limiter, which limits the sound level
when it escalates, e. g. due to feedbacks.
(9)
Volume Control Aux-Input Adjusts the correct working level of the Stereo Aux input. This control
allows to raise very low levels so that the internal working level can be
adjusted correctly.

Switch Add-on of the Aux input signal to the Shaker Line Out on the back
Aux-In to Shaker Out: of the Amp. If a stereo signal is connected at the Aux-Input, a Mono Mix
signal (Post Volume control Aux-Input) is output automatically at the
Shaker Out. The inputs of channels 1 and 2 are output at the Shaker
Out and cannot be disabled (Post Gain control Channel 1 and 2).
(11)
Aux-Input Input for an additional stereo or mono sound source (klick track, CD-
/Mp3 player, sampler...) which can be mixed to the main signal of
channel 1/2. The inputs are unbalanced. When a mono signal is looped
in only at the left output connector, the signal is internally at the left and
at the right side. When only the right input connector is occupied, the
signal can only be heard at the right side. When the Stereo/Mono switch
in the master section is adjusted to Mono Mix, the stereo signal at the
Aux Input is automatically added to mono.
