Wireless Operation
900 MHz Microphone & Beltpack Transmitter
Wireless UHF Receivers
Wireless receiver“A” is preset at the factory for channel 4 and receiver “B” is set on channel 6. There are three (3) LEDs on the receiver; power (green), RF reception (red) and Audio reception (amber).
There are also LEDs on the front of the speaker above the grille making it easy to see if the microphone and receiver are working properly. A red LED indicates RF (radio frequency) from the mic, while an amber LED indicates audio.
NOTE: There are two wireless 900MHz mic receivers on the PA919SD and PA919 (and 1 on the PA919PS). These frequencies are not compatible with any PA916 series PAs,
Wireless Transmitter
The PowerPro PA919SD incorporates a 16 channel UHF transmitter with its own power switch for wireless transmission to another PA919 or the Powered Companion Speaker PA919PS. The transmitter is preset at the factory to channel 13. It is recommended that the user not randomly change this setting. If using the transmitter function change wireless receiver “A” from channel 1 to any other channel except channel 13 to prevent the transmitter from blocking the receiver.
Microphone Lockout
Two wireless microphones can be used at the same time, but separate channels (frequencies) must be used. For instance, if using receiver “A” on channel 4, two microphone beltpack transmitters cannot be used at the same time. The first transmitter turned on will dominate and lock out the other. The second microphone should be used with receiver “B” on a different frequency which will allow two persons to talk at the same time.
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.
