Power On/Off Switch & Indicator: Turns the receiver on and off. Red light glows
when the switch is pressed. It denotes the receiver is on.
RF Level Indicators: Indicates received RF (Radio Frequency) signal strength.
Audio Level Indicators: Indicates transmitted audio signal strength from the
transmitters.
Noise Warning Indicator: Red light glows denoting the presence of interference.
Sensitivity Control: This control affects the operating range and signal quality. It
is factory pre-set at “+” position and no further adjustment is normally required.
+: (Default) High sensitivity and longest operating range.
-: Adjust counterclockwise accordingly when Noise Warning Indicator glows to
minimize interferences. However, such action decreases operating range.
Microphone Balance Volume Control: Allow users to adjust the mixed volume
level of two transmitters to a balanced or different level.
Rackmount Brackets (Optional): Allows the installation of the receiver into an
EIA-standard 19" rack.

Front Panel:
Rear Panel:
Antenna B Input Connector: To install TNC-type Antenna.
Unbalanced Audio Output Connector B (High Z / AF out): This 1/4”(6.35mm)
phone jack provides an unbalanced high impedance line level output. An unbalanced
audio cable phone plug can be used between this connector and amplifier input.
Unbalanced Level Switch:
0dB selection is for microphone-level output.
+10dB selection is for auxiliary level output.
-6dB selection is for half of cable microphone volume.
Unbalanced Mixed Switch:
MIXED - Audio signal from both Channel A & B will be mixed into Output B and no
audio output from Output A.
SEPARATE - Audio signal will be transmitted separately from Output A and Output
B.
Power Input Connector: Connect a 12 volt AC/DC power adapter to this jack and
then plug into an AC outlet.
Unbalanced Audio Output Connector A (High Z / AF out): This 1/4”(6.35mm)
phone jack provides an unbalanced high impedance line level output. An unbalanced
audio cable phone plug can be used between this connector and amplifier input.
Antenna A Input Connector: To install TNC-type Antenna.
Balanced Audio Output Connector B (Low Z / AF out): XLR connector provides
a balanced low impedance microphone-level output. Plug an XLR audio cable from
this connector to the input of a mixer. (Optional)
Balanced Audio Output Connector A (Low Z / AF out): XLR connector provides
a balanced low impedance microphone-level output. Plug an XLR audio cable from
this connector to the input of a mixer. (Optional)
