Wireless Operation
Wireless UHF Receivers
Wireless receivers should be set each at different channels, these channels must be different than the
wireless transmitter channel. There are two (2) LEDs on the receiver; RF reception (blue) and Audio
reception (amber). There are also LEDs on the front of the speaker above the grille making it easy to
see if the micro-phone and receiver are working properly. A red LED indicates RF (radio frequency)
from the mic, while an amber LED indicates audio.
Selecting a Wireless Channel
Turn the Receiver Power ON, Hold down the Set button until the display starts blinking, next, use the
Up and Down buttons to select the desired channel, lastly depress the Set button to save it.
NOTE:
There are two wireless 900MHz mic receivers on the PA920.
Wireless Transmitter
The PowerPro PA920 incorporates a 16 channel UHF transmitter with its own power switch for wire-
less transmission to another PA920 or the Powered Companion Speaker PA920PS. If using the trans-
mitter function select a different channel than the ones assigned to the receivers to prevent the trans-
mitter from blocking the mics or connecting with the receivers.
The RF power output can be adjusted between Low (5mW) and High (10mW) power settings, de-
pending on the level of interference or the range of required transmission. When there may be other
PA products used in neighboring or adjoining rooms, using the low setting will reduce the occur-
rence of experiencing any interference. With the Power OFF, simply change the RF transmit power
by moving the switch to the desired setting.
Turn the transmitter power switch to OFF when not being used to minimize battery drain.
Feedback
Feedback is a shrill screeching sound produced by the speaker system when a microphone is being
used too close to the front of the speaker. The microphone picks up the sound of the speaker system
and it becomes reamplified. It is a self-sustaining loop which can damage the system if allowed to
continue, not to mention the annoyance caused to persons nearby. Always stand 4 to 6 feet from the
speaker to minimize the opportunity for feedback from the speaker system.
