SCANNING FOR AVAILABLE FREQUENCIES
On the first receiver (A) push the SCAN button. The display will move thru frequencies until it finds the first available clear channel.
Now SYNC the first transmitter to the first receiver channel (see above).
Leave first transmitter turned on, and repeat Step 1 for the second receiver (B).
Repeat Step 2 with the second transmitter.
Keep the transmitter at least 6 feet from the receivers to prevent intermodulation interference.
If it doesn’t connect, then you will need to sync the transmitter to the receiver channel.
With receiver powered on, POWER on the first transmitter.
Hold IR window on top of transmitter about 6” away from the IR transmitter in the center of the receiver panel so they are facing each other with clear line of sight – think TV remote (only closer together).
Push the SYNC button for the receiver channel you are trying to link to
After a few seconds the transmitter and receiver should be linked – RF meter on the LCD display for the receiver channel should indicate that RF signal is present.
If the transmitter is a handheld, speak into the microphone and confirm that audio is registering on the display. If using a bodypack transmitter, connect a microphone then speak into the microphone and check the display for audio.
Repeat for the remainder of the transmitters that need to be sync’d.
CA.81 Quick Start guide
Plug RFB.PS8 Power Supply into the RFB.81R receiver, then connect the power supply into an AC outlet.
Connect the Mix Out (1/4” plug) or the 8x Balanced XLR outputs (Female XLR plug) to your mixer. Now turn on the POWER switch.
Out of the box, each microphone transmitter is matched to a receiver channel. If there is any receiver channel picking up a strong RF signal it may be necessary to scan to select a new channel. (see RF Scan).
Install batteries in each of the transmitters. Turn transmitters on one at a time, making sure it connects to just one receiver.
