4.4 Connecting an additional battery
For doubling the operating time, an addition-
al rechargeable battery of the type NPA-12 / 7
(separately available) can be connected: Use the
two connection cables (15), making absolutely
sure to observe the correct polarity (red = +) .
Guide the cables through the hole to the front
compartment of the rucksack and store the
battery there .
5 Operation
1) Prior to initial switch-on, set all volume con-
trols (2, 3, 7) to "0" to avoid an unexpectedly
high volume when the amplifier is switched
on .
2) Switch on the audio sources connected and/
or the wireless transmitter .
3) Use the POWER switch (13) to switch on the
amplifier . The LED power indicator PWR ON
(12) will light up . In addition, the appropriate
LED (10) will indicate the current charging
state of the rechargeable battery . When
the LED LOW lights up, the battery must be
☞
recharged ( chapter 4 .2) .
4) Adjust the volume of the audio sources with
the corresponding control (2, 3, 7) .
WARNING Never operate the amplifier
when the speakers are close
to anybody's ears! The high
volume may cause hearing
damage . To avoid acoustic
feedback (loud howling), never position the
speaker towards the microphone and always
make sure that there is a sufficient distance
between the speaker and the microphone .
A level limiter will automatically prevent dis-
tortions at high volumes . The LED LIMITER
(11) will light up when the limiter is active .
5) Use the control TONE (4) to adjust the desired
sound for the microphones or for an audio
source connected to the jack (1); use the con-
trol TONE (8) to adjust the sound for an audio
source connected to the jacks 3 LINE IN .

6) To automatically mute music, for example, of
an audio source connected to the jacks 3 LINE
IN (5) during announcements via the micro-
phone [VOICE OVER (9)], adjust the control
DEPTH in such a way that the LED MUSIC will
light up while speaking into the microphone .
7) To avoid unnecessary discharging of the bat-
tery, switch off the amplifier with the switch
POWER (13) after operation or during longer
pauses .
If the amplifier system is not used for a longer
period of time, completely charge the battery
prior to storage and recharge it approx . every six
months to make up for normal self-discharge .
