As an alternative, when a higher input
sensitivity is required, connect a micro-
phone to the XLR contacts of the jack
1 MIC / LINE IN* (5) .
Note:
The jacks MIC 1 (2) and MIC 2 (4) share
the same volume control; therefore, microphones
with similar electrical characteristics should be
used when these two jacks are used together .
All microphone inputs provide the phantom
power (12 V) some microphones require .
Note:
Never connect microphones or other audio
sources with unbalanced output to the XLR jacks;
they may be damaged by the phantom power .
3) To connect a
signal source with line level
(e . g . mixer, additional receiver for wireless
microphones, CD player): Use the 6 .3 mm
jack of 1 MIC / LINE IN* (5) or the RCA jacks
LINE IN (9) .
When both RCA jacks are connected
(e . g . to the stereo output of a CD player),
the signals will be transformed into a
mono signal .
When speaking into a microphone, it
is possible to mute the signal of an audio
source connected to these jacks (function
VOICE OVER
☞
chapter 5) .
4) An additional
amplifier system
or a
recorder
can be connected to the output
LINE LINK (10) . For stereo recorders, two
jacks are available . The amplifier is mono-
phonic; therefore, the signals at the two
jacks are identical .
5) The Speakon
®
-compatible jack EXT .
SPEAKER (20) can be used to connect an
additional
speaker
: Insert the speaker plug
into the jack and then turn the plug clock-
wise until it engages . To remove the plug,
pull back the safety latch on the plug and
turn the plug counter-clockwise .
If required, use the switch INTERNAL
SPEAKER (19) to switch off the internal
speakers .
* Note:
The input 1 MIC / LINE IN (5) cannot be used
together with the inputs MIC 1 (2) and MIC 2 (4);
therefore, only use the input 1 MIC / LINE IN when
the inputs MIC 1 and MIC 2 are not required .
4.3 Recharging the batteries
The lectern is operated by means of two
integrated rechargeable lead gel batteries
(12 V/ 7 Ah each) . It is not necessary to switch
on the lectern to charge the batteries; how-
ever, it is possible to use the lectern while the
batteries are being charged .
1) Connect the mains cable supplied to the
mains jack (18) and the mains plug to a
mains socket (230 V/ 50 Hz) .
2) The LED status indicators (14) indicate the
charging state: FULL, OK or LOW . The LED
indicator CHARGE will light up in red while
the batteries are being charged .
3) Once the batteries have been recharged
(the LED indicator CHARGE lights up in
green), disconnect the lectern from the
mains .
Note:
To ensure a long life of the rechargeable
batteries, disconnect the lectern from the mains
after a maximum of 12 hours .
5 Operation
1) Prior to the initial switch-on, set all volume
controls (6, 7, 11) to “0” to avoid an un-
expectedly high volume when the lectern
is switched on .
2) Switch on the audio sources connected
and /or the wireless transmitter(s) .
3) Use the switch (17) to switch on the lec-
tern . The LED indicator PWR ON (16) will
light up . In addition, an LED indicator (14)
will indicate the charging state of the bat-
teries . When the LED indicator LOW lights
up, the batteries should be recharged
(

chapter 4 .3) .
4) Replay music, for example, from an audio
source connected or speak into a wireless
microphone or a cable-connected micro-
phone .
5) Use the appropriate control to adjust the
volume of the audio sources .
LEVEL (6):
Microphones connected
to inputs MIC 1 and MIC 2
or audio source at input
1 MIC / LINE IN
2 WIRELESS (7): Wireless microphones, see
also chapter 5 .1 .2 .
PLAYER (11): Audio source at input
3 LINE IN
CAUTION
To avoid feedback howling,
never hold the microphone
towards the speaker or too
close to it . Feedback howl-
ing may also occur when
the volume is too high . In this case, use
the appropriate control LEVEL (6) or
2 WIRELESS (7) to reduce the microphone
volume .
A level limiter will automatically prevent
distortions at high volumes . The LED indi-
cator LIMITER (15) will light up when the
limiter is active .
6) Use the control TONE (8) to adjust the
desired sound for the microphones or for
an audio source connected to the jack
1 MIC / LINE IN (5) . Use the control TONE
(12) to adjust the sound for an audio
source connected to the jack 3 LINE IN (9) .
7) To automatically mute the sound of an
audio source connected to the jacks
3 LINE IN when speaking into a micro-
phone [VOICE OVER (13)], adjust the
control DEPTH in such a way that the LED
indicator MUSIC will light up when an an-
nouncement is being made .
8) To avoid unnecessary discharging of the
batteries, switch off the lectern with the
switch (17) after operation or during
longer pauses .
If the lectern is not used for a longer period of
time, completely charge the batteries prior to
storage and recharge them approx . every six
months to make up for normal self-discharge
and to protect the batteries against damage
due to deep discharge .
5.1 Operation with
wireless microphones
The lectern is equipped with a receiver mod-
ule (21) for two wireless microphones / trans-
mitters .
➍
Wireless receiver module
Each receiver section (A and B) is equipped
with a control to adjust the volume and to
switch it on and off (fig . 4) . The display is di-
vided into two parts: left half for receiver sec-
tion A, right half for receiver section B . When a
receiver section has been switched on, the dis-
play will indicate the transmission channel . To
briefly indicate the radio frequency, press the
button
(for section A) or
(for section B) .
5.1.1 Setting the transmission channels
Use the controls to switch on the receiver
sections . Do not switch on the correspond-
ing wireless microphones / transmitters for the
time being .
5.1.1.1 Channel scan
Keep the buttons
and
simultaneously
pressed for approx . 1 second until
ap-
pears on the display . The scan will start: The
receiver sections will be set to free channels
without mutual interference . If no free chan-
nels are found, the channels set will be kept .
Note:
The channel scan can also be started for one
section only (button
for section A or button
for section B) .
5.1.1.2 Manual channel selection
When
both
receiver sections A and B are
switched on:
1) Keep the button SET pressed until the
channel indication for receiver section A
starts flashing on the display .
2) Select the channel for receiver section A
with the button
or
and then confirm
with the button SET .
3) The channel indication for receiver section
B starts flashing on the display . Select the
channel for receiver section B with the
button
or
and then confirm with
the button SET .
When
only one
receiver section A or B is
switched on:
Keep the button SET pressed until the channel
indication starts flashing on the display . Select
the channel with the button
or
and then
confirm with the button SET .
Notes:
1 . The receiver sections cannot be set to the same
channel .
2 . If a channel is not confirmed within 10 seconds
with the button SET, the setting mode will be
exited and the channel previously set will be kept .
3 . If, with the transmitter switched off, the respective
segment bar A or B on the display indicates re-
ception, interference signals or signals from other
transmitters are being received . In this case, use a
different channel .
