“STEREO CD-AUX” INPUT CONNECTOR
Through the RCA phono connectors, this input permits easy connection of CD, DAT,
cassette players, etc.... .
11)
"UNBAL MIXED LINE” OUTPUT CONNECTOR
This output can be used to send the mixed audio signal to another amplified
speaker, to a recorder or to a supplementary amplifier.
To make the connection, use an unbalanced 1/4” (6.3mm) jack connector.
12) "POWER"
SWITCH
The three-position switch enables to turn the speaker on and off.
When in the INTERNAL BATTERY position, the speaker operates with batteries;
when in the EXTERNAL PSU/BATTERY position, the speaker operates only if
directly connected to the network through the PSU.
When in the OFF position, the speaker is off.
13)
“BATTERY STATUS" INDICATOR
The two-colour indicator lights up green to indicate the speaker is on and operating
correctly.
This indicator comes on red to indicate the battery is low.
14)
“ BATTERY CHARGE” INDICATOR
The red indicator stays on steady during battery recharging.
Once the battery has been completely recharged, this indicator will start flashing.
15)
D.C. POWER ADJUSTMENT AT OUTPUT POTENTIOMETER
By means of this screwdriver adjuster, the output voltage at the D.C. jack connector
(16) can be changed.
The output voltage can vary between 1 and 10VDC with maximum current 100mA.
16)
“VARIABLE VOLTAGE ” OUTPUT D.C. POWER CONNECTOR
From this connector take the power voltage for CD players, cassette recorders....or
for the active steerable antenna.
17)
“PSU /BATTERY INPUT (12-15 VDC)”
INPUT DC POWER CONNECTOR
By means of this connector it is possible to recharge the internal battery and supply
the speaker directly.
The speaker works , through direct supply, from 12 to 15Vdc voltage supply whereas
to guarantee battery recharge, it is necessary to use the 15Vdc supply interface
included.
18)
“CHANNEL” FREQUENCY SWITCH (with UHF receiver only)
This 16-position rotating switch permits selecting the radio microphone channels
(see label for corresponding work frequencies).
19)
"POWER" POWER SUPPLY SWITCH (with "TD" option only)
This switch permits turning off the TIME DELAY circuit, thereby increasing
battery life in case of non-operation.
20)
POWER SUPPLY INDICATOR “ON” (with "TD" option only)
The indicator comes on red to indicate the TIME DELAY circuit has been
switched on.
21)
DISTANCE (IN SINGLE METRES) SWITCH ("TD" option only)
This 10-position rotating switch permits selecting the distance between speakers
in single metres.
22)
DISTANCE (IN TENS OF METRES) SWITCH ("TD" option only)
This 10-position rotating switch permits selecting the distance between speakers
in tens of metres.
FOR PRESERVARE EFFICIENCY OF THE BATTERY
TO RECHARGE IT EVERY 3 MONTHS FOR 14 HOURS
2.
POWER SUPPLY
The speaker is supplied with a partially-charged battery for safety reasons. The battery
does not feature memory effect and can therefore be charged at any time. Battery speaker
operating time depends on use and it could go for 8 hours.
For replacing the battery, use only qualified and experienced personnel having
sufficient technical knowledge or specific instructions for making the
connections correctly.
When the speaker is used for the first time, the battery must be fully charged.
-
Make sure that the speaker is off (POWER switch in the OFF position).
-
Connect the speaker to the network power supply through the jack [17 - PSU
/BATTERY INPUT] using the provided for PSU.
-
The red indicator “BATTERY CHARGE” will light up.
- Leave the speaker to charge until the above indicator light starts to flash..
The battery charge will have to be checked before using the speaker. This check is
necessary because even when the battery is not used, battery efficiency declines over
time.
Switch the speaker on by means of the “POWER” switch and check the colour of the
“BATTERY STATUS” indicator:
To recharge the battery:
-
Connect the speaker though the jack [17] to the provided for DC adaptor.
-
Keep the POWER button in the OFF position.
-
The red “BATTERY CHARGE” indicator remains on steady.
-
Leave the speaker to charge until the above indicator light starts to flash. Battery
recharge time depends on battery status and can vary between about 1 to 15 hours.

First charge

Subsequent charging
[
green =
the battery is charged and the speaker can be used straight away
[
red =
the battery is low and the speaker can only be used for a very short
time. In this condition, it is best to recharge the battery.
[
off =
the battery is completely flat and the protection circuit has tripped.
In this situation, the battery must be recharged.
CAUTION !
2.2
Battery protection
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.
2.3
Mains power supply
The speaker will automatically start to operate again when the battery is recharged.
The OPERA 110 MOBILE SPORT can be used directly connected to the network, like any
active speaker.
Connect the PSU and position the POWER switch on “EXTERNAL PSU/BATTERY”;
batteries will be partially re-charged during use.
