Do not touch the INSIDE SCREWS (C).

8. TALKOVER SECTION: The purpose of the talkover section is to allow
the program playing to be muted so that the MIC can be heard above
the music. The MIC/TALKOVER SWITCH (5) controls MIC 1 and
has three settings. When the MIC/TALKOVER SWITCH (5) is in the
bottom position, the MIC and talkover are off. When the MIC/
TALKOVER SWITCH (5) is in the center position MIC 1 is on, the
MIC INDICATOR (6) will glow, but talkover is off. When the MIC/
TALKOVER SWITCH (5) is in the top position, MIC 1 and talkover
will be on and the volume of all sources except the MIC input are
lowered by 16dB. The MIC LEVEL (15) controls the level of MIC 1.
