Beyerdynamic MA 212, MA 206 Loudspeaker connection, Record Output, Mains connection, Setting up

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.
