Volume and tone control

The OPERA 110 MOBILE SPORT 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.

4.3 Outputs
The speaker features an output for the unbalanced mixed audio signal to which can be
connected another active speaker, an amplifier or a recorder (example 1).
Connection is by means of a 1/4" (6.3 mm) jack connector.
NOTE: If the TD option is used, the mixed audio signal will be delayed according to the
position of the two switches.

Example 1
BASIC 200
Several OPERA 110 MOBILE SPORT units (with radio receiver) can be used with a single
radio microphone transmitter, setting the same work frequency between the transmitter
and all the receivers. The signal from the transmitter will be reproduced simultaneously on
all the tuned-in speakers (example 2).
Thanks to an optional kit called MS 110 KIT (Integrated Antenna Transmitter) the system
can be further expanded. The kit consists of a radio repeater with integrated steerable
antenna, and extendible stand (500-850mm) and relevant connection cables.
By connecting the mixed audio signal of one of the speakers to an MS 110 KIT repeater, the
radio signal can be launched to several OPERA 110 MOBILE SPORT units (with radio
receiver) at the same time, covering a maximum distance of about 100 m (free range). The
same work frequency must be set for both the MS 110 KIT repeater and for all the speakers
to which the signal is to be transmitted (example 3).
In case a radio microphone transmitter also has to be used, a different frequency from that
used by the repeater will have to be set for both the radio microphone transmitter and for
the relevant speaker (which works as a master and will therefore be in turn connected to
the repeater) (example 4)
