as it might cause signal losses and
increases parasitic noises.
- In order to preserve a good sound
quality and prevent distortions, you
can adjust the volume by following the
instructions below:
- If you are using a microphone input of
your mixing desk or amplifier, turn the
volume to half power (approximately),
the balanced and unbalanced outputs
level will then be close to 77 mV.
- If you are using a line level input of
your mixing desk or amplifier, turn the
volume to 3/4 of the maximum power,

- This LED flashes to indicate the
batteries are almost empty and need
to be replaced or charged.
- Use the MIC/LINE located at the rear
of the transmitter box to adjust its
input level.
- Place it on MIC if you are using a
condenser microphone such as a
GOLava or GOHead.
- Place it on LINE if you want to
connect a line level device such as CD
players.
- Acquiring two GOMono allows you to
couple them into a 19" rack.
- Each receiver is supplied with screws.
- The optional coupler allows you to
bind two receivers together.

3.6 - Configuring channels
3.7 - Available frequencies
Use the faders located on your transmitter and receiver to select the carrier frequency of your
UHF system.
Your transmitter and receiver must be set on the same channel.
In order to use several mic simultaneously, choose frequencies as far apart as possible.
For instance for F8 series:
For mic no. 1 on channel 1 (823.175 MHz)
For mic no. 2 on channel 6 (827.375 MHz)
For mic no. 3 on channel 13 (863.275 MHz)
For mic no. 4 on channel 16 (864.725 MHz)
This frequency range allows the use of 4 microphone simultaneously, at full volume, in the best
environment possible.
However, the signal reception depends on surrounding disturbances that might impact on the
performances.

4 - Troubleshooting
No sound:
- Check on the power supply units.
- Check on the frequency channels - It must be the same channel on both the transmitter and
receiver.
- Check on the connectors between the receiver and the amplification system.
- Check on the transmitter/receiver distance and Squelch settings.
- Make sure the receiver is not hidden by a metallic surface.
- Check on the batteries.
Poor sound quality or interference:
- Check on the position of the antennas.
- Make sure each transmitter is on a different frequency.
- Make sure interferences are not caused by other devices such as televisions, radios, etc.
- Check on the volume of the receiver.
- Check on the batteries.
- Adjust the input gain of your mixing desk channel.
Watch out for audio feedbacks
Avoid high gain levels on your mixing desk or high volume on your receiver.
Maintain a reasonable distance from the speakers.
The feedback may cause severe damage to your hearing and sound system.
