Dual Listen Level Control

Intercom Level

I/C IN

Adjusts the level of the Intercom system’s audio into the base station. The Intercom “IN” control should be adjusted so the intercom LED flashes red on loudest speech over the intercom system.

I/C OUT

Adjusts the level of the base station’s audio out to the intercom system. The intercom “OUT” control should be adjusted so that its audio on the intercom system is equal in level to the other intercom de- vices on the intercom system. A way to adjust this level is to have someone talk into the base station with a local headset while someone else listens to the audio over the intercom system via another in- tercom device.

Auxiliary Level

These controls should be placed fully coun- ter-clockwise unless the Aux Jack is being used. Noise can be added to the system if these controls are turned up without a connection to the Aux. Jack.

Aux IN

Adjusts the level of the auxiliary input audio to the base station. The auxiliary “IN” control should be adjusted so that the LED flashes red on loudest speech. The Aux. switch controls whether the base station’s auxiliary input audio is ”ON" or “OFF”.

Aux OUT

Adjusts the level of the base station’s audio out to the auxiliary connector. The auxiliary “OUT” con- trol should be adjusted so that its audio is equal to other devices on the auxiliary system. The base sta- tion’s audio is always supplied to the auxiliary jack regardless of the auxiliary switch position.

Controls, and Sidetone Level Controls

Sidetone Level

Local Sidetone

This control adjusts the voice feedback to the ear- phone of a headset plugged into the base station.

Beltpack Sidetone

The beltpack control adjusts the voice feedback to the earphone of the beltpack’s headset.

NOTE: “Mirror Image” beltpacks have the ability to communicate beltpack to beltpack direct. The belpack sidetone on this version is controlled by a level control on the beltpack, see Figure 51. If a base station is used with one of these special beltpacks, then its beltpack sidetone control would have no effect on the beltpack.
