6.3 Location Recording or Broadcast

Mixing:

In this setup the MX-508 is used to mix

sources typically found in location re-

cording or broadcast situations (mostly

microphones). In this case, two of the

microphones are wireless types, so the

channel input actually comes from the

microphone receivers. Since the out-

put from the mic receivers is at line

level, the input selectivity of the re-

spective channels must be set accord-

ingly. The Tape Out jack feeds a

portable tape recorder, and the tape

recorder's line output is brought back

to the Tape/CD Input connectors for

monitoring. For live remote broadcast applications the Mono Out connector can feed a suitable TELCO interface.

7. CHANGING FACTORY CONFIGURATIONS

7.1 Changing the Aux Pre/Post Assignment

The MX-508 is shipped from the factory with Aux 1 assigned Pre-Fader/EQ, and Aux 2 Post-Fader/EQ. Each

channel's Aux Send controls may be independently configured for either pre or post fader/EQ operation with a minimum

of tools and no soldering. To make this change, refer the fol-

lowing procedure to a qualified service technician:

Remove the bottom cover which is fastened by seven 6-32

screws. Locate the 3 pin headers labeled Send 1 and Send 2

near the front of each input channel circuit board (see dia-

gram). Remove the shunt bar from the factory installed posi-

6.4 Submixer In Larger Sound

System:

In this application the MX-508 is used

to provide a drum mix to the main

mixer without tying up a number of

channels on the main console. Up to

eight mics can be "pre-mixed" in ste-

reo, with all drum-specific gating,

compression, and effects controlled

directly by the drummer. Either the

main OUTPUT or the SUB OUT con-

nectors can be used to feed the mixed

drum signal to the main mixer. If

there is significant distance between

the MX-508 and the "master" mixer,

use the pseudo-balanced or trans-

former-balanced Main outputs for

long cable runs, otherwise use the un-

balanced Sub outputs.

Unplug the unit's AC power cord from the outlet.
