3 OPERATION
3 . 1 D Y N A M I C M I C R O P H O N E S
Dynamic microphones are characterized by lower output levels. Hence,
more gain is needed to amplify a dynamic microphone to operating level.
Occasionally it is necessary to add the –20dB pad to the microphone to
avoid distortion (e.g. when recording percussion). Do not use phantom
power when using dynamic microphones.
3 . 2 P H A N T O M P O W E R E D
Phantom powered microphones such as condenser and some ribbon
microphones require external power to pre-amplify the microphone
acoustic pickup. These microphones typically have much higher output than
dynamic microphones. Hence the –20dB pad is almost always necessary
when close mic-ing to avoid clipping the amplifier.

The VXP features a send jack and a return jack. This feature allows the use
of external processors such as reverbs and digital devices. Simply connect
the send jack, balanced or unbalanced to the input of the external
processor. Then connect the VXP's return jack to the output of the external
processor. The signal is now routed out of the VXP, into the external
processor, then back into the VXP. The final, processed signal will be
available at the VXP output connector.

The return jack can be used to insert external audio devices such as tape
machine outputs, DAT machine outputs, etc.
