4.2. Connection possibilities

The ATA1-1R has an internal mixer allowing the signal from the telephone line and the program
signal to be present on the output. Using the "PGM BYPASS" switch located on the backside of the unit it is
possible to select if the program signal has to be mixed with the telephone line signal or not. The position of
this switch depends on the actual connections. The ATA1-1R has to be turned on to allow the program
signal to pass through.

4.3. Connections

The telephone line has to be connected to the "LINE" input and the telephone to the "TEL" output
using RJ11 connectors.
The input signal has to be connected to "PGM IN" input and the output signal to "OUTPUT". The audio
signals use RCA connectors.

4.4 Connection examples

Option 1: Using the "AUX OUT / AUX IN" from the auxiliary bus from a mixing desk.
Option 2: Using the "SEND / RECEIVE" function from the main mix bus (or the mixer's main output;
in this case the ATA1-1R's "OUTPUT" can be used as general output)
Option 3: Using the "SEND / RECEIVE" from the speaker's mic channel. In this case only the voice would
be sent to the telephone line, but not the music.

4.5 Operation guide

With the switch (1) in "TEL. SET" position, the listener can be called using the telephone. This
signal will not be present on the ATA1-1R's output.
To hold the telephone line, the switch has to be put to "HOLD" position. After that, the telephone
can be ringed off. In this situation the listener hears the signal connected to "PGM IN" input (7), but his
voice will not leave the "OUTPUT" (9).
Putting the switch in "ON AIR" position, the listener's voice can be heard. The level can be
adjusted using the "VOL" pot (3).
The line adjustment can be done with the "IMPEDANCE ADJ" control (2). With a call on line this control
has to be adjusted until the level difference between the "HOLD" and the "ON AIR" position is as low as
possible, having the volume (3) at maximum.

5. CLEANING

The front panel should not be cleaned with dissolvent or abrasive substances because
silk-printing could be damaged. To clean it, use a soft cloth slightly wet with water and neutral liquid
soap; dry it with a clean cloth. Be careful that water never gets into the amplifier through the holes of the
front panel.
