MIC-AMP

This two channel pre-amp is designed to be the answer for extremely high quality microphone amplification

especially on equipment which only are provide with line inputs.

It transforms the balanced microphone-level signal to an unbalanced -10 dBV line-level signal to correspond

to the line inputs on other equipment, for example P.C.M.-units and DAT/DCC recorders

SETTING UP PROCEDURE

Connect the microphone to the input of the MIC-AMP and the output of the MIC-AMP to the equipment it

should be connected to.

GAIN

When a signal at the input is present the normal led lits regularly. (is green)

Turn the gain clockwise until the clip led lits sporadic.

48 VOLT PHANTOME POWERING

For condenser microphones a 48 Volt phantome is provided per channel.

You will not hear any click while switching. This phantome circuit uses a softswitching arrangement.

This means the voltage is built up slowly. It is active after about 8 seconds.

The phantome power does not effect dynamic microphones when the microphone, cables and plugs are wired

symmerical. (balanced).

Be sure, that your microphone wiring is balanced to keep optimum signal to noise ratio.

PHASE

The phase switch reverses the wiring of the microphone input, so it changes the polarity of the connected

microphone. This can be useful when two microphones are out of phase or cancellations are to be heard in

the low frequency range.

CONNECTIONS

It is recommended to unplug the MIC-AMP from the mains outlet, before making the following connections.

Reconnect the mains-lead after the connections have been completed and make sure they are secure.
