Radio microphone

With the receiver incorporated in the OPERA 110 MOBILE speaker, both a hand
transmitter and a pocket (belt) transmitter can be used.
The latter features special audio accessories (Lavalier microphone, instrument or
headset cable) and a clip for belt fastening.
If the transmitter is of the mono-frequency type, select one of the 16 available channels on
the speaker in accordance with the transmitter work frequency; in the case of a multi-
frequency, select the same channel on both the receiver and the transmitter.
Frequency selection can be made by means of the channel switch.
The volume of this input is regulated by means of the WIRELESS VOLUME control.

Volume and tone control

The OPERA 110 MOBILE features separate volumes for the various inputs which can be
regulated independently and a general volume that controls the mixed signal at output.
This is why, when using the speaker, you should always remember to regulate both the
volume of the signal/s at input and the general volume.
Tone control involves the microphone channel inputs to permit adjusting voice tones.
If there is no audio signal, the speaker switches to standby mode after a few minutes
to save the battery and not create disturbances.
As soon as the audio signal returns, the speaker will start up automatically.
During low-volume use, the automatic switch-off circuit could come on. To prevent this
standby mode, set input volumes high and general volume low.
