Applications - IMG STAGELINE LTR-106 Mode D'emploi

GB
If the unit is to be put out of operation definitively, take it
to a local recycling plant for a disposal which is not
harmful to the environment.

3 Applications

The LTR-106 has four separate audio channels which offer the
following facilities independent of each other:
1. DC isolation between a signal source (e. g. instrument, micro-
phone, computer, etc.) and the following unit (e. g. amplifier,
mixer, effect unit, etc.).
2. Reduction of interferences (e. g. humming) in long signal
lines by reducing the output impedance of the signal source.
3. Reduction of interferences in long signal lines via balanced
signal transmission.
4. No hum loops when separating the ground between input
and output.
5. With wrong phase of the signal, the phase can be reversed
by 180°.
6. Adaptation of XLR connection to 6.3 mm connection and vice
versa.
7. Adaptation of balanced to unbalanced connection and vice
versa.

4 Operation
The following operating instructions refer to one channel and
are to be performed correspondingly for the other channels.
1) Switch off all units before connecting them to the LTR-106!
2) Connect the signal source (instrument, microphone, com-
puter, etc.) to the input via one of the 6.3 mm jacks (1+8) or
the XLR jack (9). The input jacks (8+9) at the rear will be
switched off if the input jack (1) at the front is connected, and
the XLR jack (9) will be switched off if the 6.3 mm jack (8) at
the rear is connected.
The connection cable between the signal source and the
LTR-106 should be as short as possible in order to reduce
inter ferences.
3) Connect the following unit (e. g. amplifier, mixer, effect unit,
etc.) to the output via one of the 6.3 mm jacks (5+7) or the
XLR jack (6). The output jacks (6+7) at the rear will be
switched off if the output jack (5) at the front is connected,
and the XLR jack (6) will be switched off if the 6.3 mm jack (7)
at the rear is connected.
4) Switch on all units which are connected. With the volume at
the amplifier always reduced, operate the switches (2–4) of
the LTR-106 as follows.
5) Should humming occur, press the GND switch (4) and/or
RATIO switch (2) to eliminate or reduce the humming. The
RATIO switch (2) should always be pressed when using long
