Microphone
PG185 Lavalier microphone OR
PG30 Headworn microphone
Power
Plug in the power adapter to turn on the receiver. There is no power switch.
Insert 2 AA batteries into the transmitter. Hold the power button for two seconds to turn on.
Connecting to a Sound System
Connect the balanced XLR output on the receiver to a MIC or LINE input. Set the LINE MIC switch accordingly.
If there is no XLR input, connect the unbalanced 6.35 mm (1/4 inch) receiver output to a LINE input. Set the LINE MIC switch to
LINE.
Channel
Set the transmitter and the receiver to the same frequency using the channel dial.
Note: If using a dual system (or more than one single system), assign each input to a different channel within the same group (channels 1-4 or channels A-D).
For the JB1 band, there are three groups: channels 1-3, 4-6, and 7-8. This ensures the best signal quality.
Bodypack Gain
The gain dial controls the audio volume sent to the receiver.
Turn down the gain if the audio signal sounds distorted.
Turn up the gain if the AF LED light is faint or the audio is too low.
RF Level
This switch sets the RF level of the handheld transmitter. It does not affect the audio volume.
Set to LO to avoid interfering with other receivers when in a building with multiple systems.
Set to HI for transmitting over a greater distance when using a single system.

Squelch
Squelch controls the amount of RF signal that the receiver picks up.
Turn up the squelch dial (clockwise) to remove ambient noise from unwanted RF sources.
Turn down the squelch dial (counterclockwise) if the microphone is not transmitting clearly to the receiver.
Color ID Rings
Slide these color rings over the handle of the microphone to identify them. (Sold in a package of six as an optional accessory.)
