3. RADIO MICROPHONE
OPERA 110 MOBILE SPORT can be equipped with a receiver that operates in the UHF
band or VHF band.
The receiver of the radio microphone incorporated in the OPERA 110 MOBILE SPORT
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.

3.2 VHF receiver
The radio-microphone receiver incorporated in the OPERA 110 MOBILE SPORT, which
works in VHF band, is a mono frequency unit. The frequency is selected at the time of
ordering the speaker.
The carrier frequency of each transmitter is indicated by a coloured code for easier
identification.
The carrier frequency of the receiver is indicated on the rear of the panel by a label showing
both the colour code and the frequency in figures (e.g. 175.750MHz)
The transmitter and the receiver must work on the same carrier frequency.
The receiver features a single antenna incorporated in the 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.

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.
With the receiver incorporated in the OPERA 110 MOBILE SPORT 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.
In the case of a UHF transmitter of the mono-frequency type, select one of the 16 available
channels on the speaker according to the operating frequency of the transmitter; in the
case of a multi-frequency, select the same channel on both the receiver and the
transmitter.
Any one of the frequencies can be selected by means of the channel switch.
In the case of the VHF transmitter, make sure the carrier frequency of the receiver and
the transmitter are the same by means of the colour code or frequency in figures.
The volume of this input is regulated by means of the WIRELESS VOLUME control.
