4.4 Loudspeaker connection
The loudspeaker is connected to the loudspeaker terminal board (10). The
output voltage of this socket is 100 V at full modulation. Low-impedance loud-
speakers with an impedance of 4 to 16 Ω can be connected to the terminals
4 - 16 and COM of the terminal board (11).
Caution:
A simultaneous operation of 100 V and low-impedance loudspeakers will
destroy the amplifier!
The MA 206 mixer amplifier is suitable for the connection of loudspeakers with
100 V-matching transformer. If these loudspeakers are connected to a 100 V ampli-
fier output, they receive the power depending on the matching. All the connected
loudspeakers or their power matching result in the total power consumption. The
total power consumption must not exceed the rated amplifier power, or the ampli-
fier may be damaged.
4.5 Record Output
The record output (12) is unbalanced (0 dB), for the connection of recorders.
The audio signal is the master of the microphone and auxiliary inputs before the
equalisation and volume controls.
4.6 Mains connection
The mains cable is fixed and equipped with a ground contact.
5. Setting up
After all connections such as mains, microphone and loudspeakers have been
completed; follow these steps to bring the system up:
1. Turn all volume controls to “0”.
2. Turn on the source equipment.
3. Turn on the MA 206 mixer amplifier with the ON/OFF-switch (8).
4. Turn the corresponding volume control half up, with the output level control of
the source equipment turned down. There should be no audible hum. If hum is
heard, check the connections between the sound source and the mixer amplifier.
5. Using the volume control microphone (1) you can adjust the volume of the indi-
vidual microphone inputs.
6. Using the volume control master (5) the desired volume in the room is adjusted.
7. The volume of the sound carrier input is adjusted with the volume control (3)
independent of the master volume control.
8. Activate a signal.
