SHORTING MUTE IN TO LOGIC GROUND INTERNALLY
This modification is equivalent to shorting a channel MUTE IN to the
LOGIC GROUND pin via the high density DB-15 logic connector. With this
modification, a channel is always muted.
Procedure:
1. Short jumper X1004.
DISABLING AUTOMATIC MIXING FUNCTION BY CHANNEL
This modification removes a given channel from the IntelliMix automat-
ic mixing circuitry, so that a source such as music can be played through
a channel of the SCM410 without affecting the automatic mixing of the un-
modified channels.
Procedure:
1.
If necessary, modify the channel input to accept line level sig-
nals. Refer to the
Inserting an Input Line Pad paragraph.
2.
Modify the channel's Override In to On. Refer to the Shorting
Override In to Logic Ground Internally paragraph.
3. Short jumper X1001 to remove the channel from the MaxBus.
4. Remove R1064 to remove the channel from the Last Mic
Lock-On Bus.
MANUAL MODE ENABLE
This modification defeats the automatic mixing functionality of the
SCM410, so that it operates as a standard 4 x 1 mixer.
Procedure:
1. Short jumper X9001.
