Make sure the D.C. adapter is compatible with the power voltage required by the
speaker (12-20VD.C.).
In the case of power supplies below 16VDC, complete battery charge will never be
achieved.
The speaker will automatically start to operate again when the battery is recharged.
The OPERA 110 MOBILE can be used connected directly to the mains like any speaker
that operates only when the battery is charged or partially charged, by means of one of the
two recharge points.
The receiver of the radio microphone incorporated in the OPERA 110 MOBILE works in
UHF band with a choice of 16 channels (frequencies). Frequency selection can be made
by means of a rotating switch. For the correspondence between selected channel and
work frequency, refer to the label on the panel.
The receiver is based on the “diversity” principle as it features two separate antennas
used to select the best radio signal at any time. The antennas are incorporated in the
receiver board inside the speaker.
A switch is fitted for excluding the radio microphone circuit in the event of this not being
used. This permits longer battery life and excludes the circuits that are not used.

2.2 Battery protection
2.3 Mains power supply
The speaker features a circuit that assures correct battery operation and protects this
from complete discharge.
When this protection trips, it means battery operating voltage has dropped below
minimum established value (about 9 V.).
The tripping of the protection is first of all indicated by the lighting up of the red “BATTERY
STATUS” indicator; afterwards, the speaker is turned off altogether. The interval between
these two stages depends on use.
The recharge circuit is always operative with mains power supply.
If, during operation, there is a power break and the battery is charged, the speaker will be
automatically powered by the battery without any interruption occurring.
4. USE
By means of the RCA connectors, the STEREO CD-AUX inputs ensure easy connection
to DAT, CD, cassette or reel players, etc... This input is mainly used for listening to
recordings.
The volume of these inputs is regulated by means of the CD-AUX VOLUME control.
The MIC/LINE BAL mono input can be used as a balanced microphone or line input. The
input level can be selected by means of the sensitivity switch above the connector.
If musical instruments are used (e.g.,: guitar, bass guitar, keyboard), mixer or CD player,...
use the input with LINE sensitivity, while for wire microphones, use the input with MIC
sensitivity. The XLR connector or 1/4" (6.3 mm) jack can also be used.
The volume of this input is adjusted by means of the MIC/LINE VOLUME control.
4.1 Inputs
4.1.1 CD-AUX input
4.1.2 MIC/LINE inputs
4.1.3 Radio microphone
4.2 Volume and tone control
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.
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.
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.
The volume of this input is regulated by means of the WIRELESS VOLUME 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.
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.
Several OPERA 110 MOBILE units 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 units 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)
