Speaker, Inputs, and Volume Control: Two audio inputs are provided. The inputs are combined internally and sent
as a monaural signal to the internal speaker amplifier. The Volume control adjusts the level to the front panel
speaker. Typically, these inputs are used with the speaker outputs of a master station when the master station is set
for use with a panel microphone and speaker instead of a headset.

Combine / Isolate Switch: When in the Combine position, the unit will combine the audio signals of the two
channels to create a single audio channel where all users can intercommunicate. When in the Isolate position, the
unit will create two groups of completely independent users.

Channel Status Indicators: The indicators are green for normal operation and red when there is an overload or
short circuit. The circuitry in the unit will automatically reset when the overload or short circuit is located and
fixed.

Universal AC Power Input: The unit accepts any input power in the range of 100-240 VAC, 50/60 Hz.

Intercom Channel Connectors: When the Combine / Isolate switch is set to the Isolate position, each channel
connector is powered separately and has completely separate intercom audio. When the Combine / Isolate switch
is set to the Combine position, each channel is still powered separately, but the audio signals are combined so that
all users on both channels can intercommunicate.

BAL / UNBAL Selector Switch: This selector switch allows the user to configure the unit for use in either an
Audiocom® (BALANCED) or Clear-Com (UNBALANCED) system. Compatibility includes channel connector
pin-outs, channel power requirements, and call signaling requirements. The default setting for this switch is in the
Audiocom® (BAL) position.
