Adjusting Gain
Monitor the audio LED indicator on the receiver front panel when setting the transmitter gain.
Green
: normal levels
Red
: excessive sound levels (overload).
The red LED should only illuminate infrequently when you speak loudly or play your instrument loudly.
BLX1
Rotate the audio gain adjustment to increase (+) or decrease (−) the gain until desired level is reached.
For instruments, turn gain to minimum setting. For lavaliers, increase the gain as desired.
BLX2
The BLX2 features two gain level settings, default and attenuated (-10 dB). The default setting is used for most situations. If the
receiver audio LED flickers red often, set the microphone to attenuated. Use the channel button to change the gain setting.
Hold down the channel button for 5 seconds.
A dot appears on the lower righthand corner of the LED display, which indicates −10 dB gain setting has been activat
ed.
To change the gain back to default, hold the channel button again for 5 seconds, or until the dot disappears.
