DUAL-CHANNEL RECEIVER CONTROLS
Front Panel:
LCD
Liquid Crystal Display shows battery status and frequency settings. (Use the Dual-channel Control
Switch to select frequencies for Receiver Channel 1 and Receiver Channel 2; in Hold position, only
Receiver Channel 1 frequency appears in LCD.)
Antenna Input Jacks
BNC-type antenna connectors. Antennas A & B (split internally) both provide signals for Receiver
Channel 1 and Receiver Channel 2. Attach the antennas to the antenna input jacks. Make certain
that during operation there is a clear open-air path between the receiver antennas and the
transmitters.
Diversity Indicators for each antenna for each receiver
True Diversity operation: two antennas feed two completely independent RF sections on the same
frequency for each receiver; automatic logic circuitry selects the superior signal.
Diversity Indicator 1 indicates which tuner has the better reception and is in operation for Receiver
Channel 1; Diversity Indicator 2 indicates which tuner has the better reception and is in operation
for Receiver Channel 2.
Power Switch with four positions: External, Off, 1, Both
Turns the unit on and off.
Choose “External” (far left position), if the unit is connected to an external power supply (12V DC
source, 500 mA nominal current, not included). In “External” position, both receiver channels are
activated (indicated by illumination of power/peak LEDs 1 and 2).
Choose “Off” to turn the unit off.
Choose “1” to activate only a single receiver channel (Receiver Channel 1, indicated by the
illumination of power/peak LED 1). This conserves energy if you are only using one audio channel.
Choose “Both” to activate both receiver channels (indicated by illumination of power/peak LEDs 1
and 2).
Note: Selected receiver will be muted unless Dual-channel Control Switch (to right of Power
Switch) is in Hold position.
Power/Peak LED
Indicates which receiver channel(s) is (are) in operation. Also indicates receiver overload by
turning off; too much signal will cause blinking LED (off during peaks). To correct overload, adjust
audio gain on transmitter. (See ….)
Dual-channel Control Switch with three positions: 1, Hold, 2
This switch allows you to use the single LCD window to control each of the two receiver channels
separately.
To set frequency for Receiver Channel 1, switch to 1 (left position).
To set frequency for Receiver Channel 2, switch to 2 (right position).
To lock settings and operate unit, switch to Hold (center position).
Note: Receiver Channel 1 is muted when switch is at 1; Receiver Channel 2 is muted when switch
is at 2; both channels un-mute when switch is at Hold.
Dual-channel Control LED
This LED is red when switch is in position 1, indicating muted operation for Receiver Channel 1.
