6. OPERATION
If several active speaker systems are required of PA application, a wireless audio link mode is possible via
the transmitter module
ALT-105
. Via the transmitter unit of an
W.A.M.S.-05
active speaker system, the
mixed signal can be transmitted to the receiving units of further
W.A.M.S.-05
active speaker systems
-
unaffected by the Master control and by the Tone controls.
M
To switch on the transmitter module, advance the On/Off/Volume control from the position “OFF“. The LED
TX lights up to indicate transmission of a radio signal.
M
For the audio link mode, adjust the transmitting unit of the primary system and the receiver units of the
secondary systems to the same transmission channel:
M
Press the SET button. The channel indication on the display starts flashing.
M
The channel indication keeps flashing for approx. 10 seconds. Meanwhile, the channel can be selected
with buttons
N
and
O
.
M
Confirm the channel selection with the SET button (within 10 seconds) otherwise the unit returns to the
channel previously adjusted.
When selecting the channel, make sure that the transmitter unit and the receiver units of the primary
system are set to different channels. Otherwise, there will be feedback.
M
To indicate the frequency instead of the channel on the display keep one of the buttons
N
or
O
pressed.
(Please refer to chapter 8
.1 Accessory
for a table listing which channel is assigned to which frequency).
M
The LEDs AF LEVEL indicate the level of the audio signal fed to the transmitter unit.
The yellow LED lights up when the input signal of the transmitter unit has reached a certain minimum level.
The red LED lights up when the input signal of the transmitter unit has reached the maximum level where it
is close to overload. The LED should not light up or light up only shortly with signal peaks. If it lights up
permanently, the signal is overloaded. In this case, reduce the volume of the corresponding signal source
accordingly
M
Adjust the desired volume for the audio signal transmitted with the Volume control.
