Telex TR-825, BTR-800 dimensions Auxiliary Input/Output, Internal Auxiliary Input Routing Switch

Auxiliary Input/Output

The input and output 3-pin XLR auxiliary connections are for supplying additional balanced audio into and receiving bal- anced audio from the base station. The output auxiliary con-

nection only interfaces to intercom B. However, there is an internal switch to control the routing of the input auxiliary au- dio. See the "Internal Auxiliary Input Routing Switch" section of this manual.

The input and output auxiliary audio is global. This means the input auxiliary audio is placed on the base local headset, beltpack(s), headsets, and any wired intercom system inter-

faced to the base station. The intercom channel(s) the input

auxiliary audio is placed on depends on the position of the in-

put routing switch.

The output auxiliary audio is also taken from the intercom B base local headset, beltpack(s), headsets, and any wired inter- com connected to the base station. A modification document is available from Telex Communications for those who wish to modify the base station so that auxiliary input audio is heard only locally; base local headset and beltpack(s) headsets.

Internal Auxiliary Input Routing Switch

This switch controls the routing of the input auxiliary audio. This switch has two positions. The "B" position places auxil- iary input audio onto intercom B only (default from factory). The "A & B" position places auxiliary input audio onto inter- com A and B. Please see Figure 23 for the location of this in- ternal auxiliary input routing switch.
