Auxiliary Input and Output Functions
The base station Auxiliary input and output are used for different purposes depending on the system
configuration. In Single, Not Distributed mode, the Auxiliary input can be mixed with other sources
and delivered to any output. This allows an input such as program audio to be fed to all Beltpac
users, wired intercom users, or simply monitored by the local headset. In this mode, the Auxiliary
output may be used as a secondary paging channel (without relay contacts) when Beltpacs are
configured for Talk Aux, or as an output to monitor any combination of inputs.
When the base is configured for Single, ISO+ mode, the Auxiliary input and output work together as
an additional isolated four-wire intercom channel. Any input is delivered to all Beltpac users on both
transmitters. Any Beltpac user pressing an ISO button will be heard through the Auxiliary output.
In Master/Slave modes, the Auxiliary input and output are used to distribute receiver audio from the
Slaves up to the Master. See the section on Cascading Bases for more information. In that situation,
be sure to leave the Master slider in its 0 dB position.
Page Output Mixing
Select the box next to Ch1, Ch2, Rx1-Rx4, Aux and/or Mic to enable input, then use the
corresponding slider to adjust output level in 0.25dB increments for the desired mix.
Check the boxes for Rx1-Rx4 only if you want receiver audio continuously fed to the Page Output.
Leave them unchecked for normal operation.
Adjust the Master slider to match the audio level from the PRO850 to the paging amplifier.
Headset Output Mixing
Separate mixers are provided for left and right earpieces. When a single-earpiece headset (4-pin) is
used, the left and right signals are combined at the output.
Select HSL (headset left) or HSR (headset right), then select the box next to Ch1, Ch2, Rx1-Rx4, Aux
and/or Mic to enable input. Use the corresponding slider to adjust output level in 0.25dB increments
for the desired mix.
Check the boxes for Rx1-Rx4 only if you want receiver audio continuously fed to the Headset Output.
Leave them unchecked for normal operation.
Master Level slider adjusts the overall headset audio output level in 1.5dB increments.
NOTE: the headset volume control (front panel knob) adjusts the outputs to both HSL and HSR
simultaneously.
