Up to 10 compatible channels
To perform a frequency scan on the XS Wireless products follow these steps:
1) Press the "UP" or "DOWN" button to scroll through the menu options on the receiver.
2) Press the "SET" button to select the SCAN option. NOTE: The unit automatically selects the next available unused frequency.
Once the new frequency is selected on the receiver the transmitter needs to by synced to the receiver. To do this follow these steps:
1) Press and hold the "SYNC" button on the transmitter until the "SYNC" symbol flashes on the receiver.
2) Press the "SYNC" button on the receiver.
NOTE: If a frequency SCAN is performed and no available frequencies are found then the SQUELCH setting will need to be increased. Once the SQUELCH setting has been increased repeat the steps of the frequency scan and then SYNC accordingly.
There are two settings that have the greatest effect on sound quality:
This is how sensitivity the microphone pick up is and this is adjusted on the microphone/body pack itself. Typically for general speaking the sensitivity should be set around -15 to -18 dB. You will need to adjust this depending on the exact application. Adjusting closer to 0 dB is will be more sensitive and further away from 0 dB is less sensitive. If the microphone is too sensitive the input will overload the microphone and the AF level will peak and the audio will be clipped. It is suitable to adjust the level so that the AF peak indicator lights up only briefly during the loudest passages.
This is how strong the signal is exiting out of the receiver into the sound board/speakers/etc. Typically this will be set to 0 dB or +6 dB if connected to equipment which is expecting a line level input . If you are connected to equipment expecting a mic level input you will typically need to drop this AF output down to -24 dB or -30 dB. If your equipment has the option, it is best to try to run the equipment in line level mode.
NOTE: If the AF Output is too high it may over load the input on any connected equipment (sound board/speakers/etc) and may create noise in the form of distortion/rumbling.
Not having audio coming from a microphone could be caused by a few different scenarios.
Firstly check that the transmitter and receiver are both on the same frequency as this is key to the system working.
Next check to make sure that the "MUTE" switch is not accidentally engaged (either fully or partially). The best way to do this is click the mute switch on and then back off.
After checking the "MUTE" switch if no audio is present make sure that the microphone element is securely in place. If using a body pack transmitter make sure that the microphone or guitar cable is securely in place by disconnecting it and reconnecting it. NOTE: On the handheld microphone the capsule is locked into place and cannot come loose.
If you are seeing RF and AF levels on the receiver but do not have any sound through your system it would be recommended to check the cables between the receiver and sound system, check the inputs on the sound system and check the AF out level on the receiver to ensure that it is set to the appropriate level for your sound system.
