No or Low Audio
If you are not getting audio through the system, carefully re-check all setups. Especially
note that the receiver and transmitter must be set to operate on the same RF channel.
Make sure that the receiver Power Switch (2) on the MGT-16 receiver is not in the second
position (audio muted/attenuated). The receiver’s Unbalanced Audio Out (7) is adjustable,
so make sure the Volume Control (3) is set properly.
RF Interference and Finding Open Channels
If you encounter slight receiving interference when the transmitter is far from the receiver,
it can often be overcome by adjusting the receiver‘s Squelch Adjust (13) (see Adjusting the
Squelch on page 8). If you receive interference on a selected channel with the transmitter
Off, you must reprogram the receiver and transmitter to a different channel.
To reprogram, you must first find an open channel. To do this, follow the operating
procedure outlined in Selecting the MGT-16 Receiver Channel and IR Sync on page
8. With the transmitter Off, change the receiver DIP switches setting to one of the
16 channels until you find one for which the Signal LED (10) doesn’t flicker or light up.
Also, for optimal interference-free operation, the Signal LED must not flicker or light up
on any of the three immediately adjacent channels, both above and below the selected
channel (i.e., a field of seven adjacent channels, with the chosen channel in the middle,
should all be clear). If operating multiple MGT-16 systems simultaneously, repeat
this procedure every time a new channel is selected, with all other transmitters and
receivers turned on.
It is important to note that wireless frequencies are shared with other radio services.
According to current FCC regulations, wireless microphone operation is not protected from
interference from other licensed operations in the band. If any interference is received
by a government or non-government operation and wireless microphone use is deemed
responsible for the interference, the wireless microphone must cease operation or change
frequencies. Note: This requirement is applicable in the U.S. only.
Note: If the Signal LED is lit, this indicates good signal strength in operation. If the Signal LED remains
lit with the transmitter Off, this indicates the presence of likely RF interfering signals at that location.
Should this occur, select a different channel.
