Basic Operation

This section explains basic operation of the EMX640.

Connecting microphones and instruments

1
Before connecting mics or instruments,
make sure that the power of all equip-
ment (where applicable) is turned off.
Also make sure that the level controls of
each channel of the EMX640 and the
MASTER control of the MAIN section are
turned down.
2
Connect cables to your mics and instru-
ments, and insert the other end of the
cable firmly into the appropriate Lo-Z/Hi-
Z jack (channels 1~4) or the MIC/LINE
jack (channels 5~6).
Note: When connecting a line level device to
channels 1~4, turn on the PAD switch.
You cannot use a channel's Lo-Z and Hi-Z jacks
at the same time. The MIC and LINE jacks,
however, can be used at the same time.
