23) CD stereo input / AUX input, 500mV: Use these stereo RCA inputs to connect a line level source such

as CD players, MD players, etc…. You have to make your choice with the selector at the front (see 12).

Stereo signals will be summed together.

24) Line 4, input, 200mV/ Mic 4 input. Use only one of these parallel wired inputs at the time! For line levels

see 24. To the XLR3 balanced input you can connect any microphone using a balanced, two wire shielded,

cable. (1=earth / 2 =hot / 3=cold). For using condenser microphones see 34. The Microphone 4 input is

a XLR3/combo jack, which will accept a normal XLR3 male plug or a ¼” TRS phone jack.Line 4 is more

sensitive than the other line (music) inputs, therefore ideal to connect wireless microphone receivers.

25) Mic 2 & 3 XLR inputs. To the XLR balanced input you can connect any microphone using a balanced, two

wire shielded, cable. (1=earth / 2 =hot / 3=cold). For using condenser microphones see 34.

26) Mic 1 XLR/DIN5/Euro block input. Use only one of these parallel wired balanced inputs at the time! See

wiring diagram at the back. These three inputs have been wired in parallel with the balanced jack input at

the front. When you use the APart MICPAT paging microphones, connected directly to the DIN5 input, the

signals fed into the line inputs are muted automatically while paging. The same kind of connection can be

made using the euro block connector. To use “vox mute” see 28.

Phantom power: use condenser microphones see next page.

27) Vox mutes all. When you activate “vox mute” by turning this trimmer clockwise to the desired threshold

level, the signal of any Mic1 input has priority. When you don’t need “vox mute”, turn this trimmer fully

counter-clockwise to the “OFF” position.

28) Priority over music contact. By closing the contact of the euro block connector or contacts 4 and 5 of the

DIN5 connector, the signal of microphone 1 only has priority over the music sources (TUNER, CD and

AUX). All other microphones will remain active. The contact closure of the contacts mentioned can give

priority to the other microphone inputs as well. At the same time 24 V DC will be available at terminal 20.

This is very useful when using up to 4 microphones in supermarkets, etc…

29) Chime level. When one of the priority contacts are closed a chime can be activated by turning this trimmer

clockwise to the desired chime level. When you don’t need a chime, turn this control fully counter-clockwise

to the “OFF” position.

30) Emergency / telephone input. Here you can feed the audio source for paging emergency messages, etc..

This input, at line level, has automatic activation above 200mV and has a line transformer to avoid ground

loops (useful for telephone). Please use a balanced, shielded line cable. Connect the HOT signal to +,

the COLD to and the shield to G (when connecting the shield only at the MA200 side, you might avoid a

ground loop, which creates hum and buzz). This signal is directly fed into the main amplier.

No microphones should be connected directly to this input without using a mic to line pre-amplier.

31) Emergency / telephone level. With this potentiometer you can set the desired level of the line level signal

inserted into the priority signal input 32. This level will not be inuenced by the “master” level.

32) Airow output. This airow output should be kept free at all times! To give the fan a longer life time, he only

starts running when the heatsink reaches a certain temperature.
