Technical Specification - dB Technologies OPERA 110 MOBILE Bedienungsanleitung

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)
