Mic/Line Switch; Signal Indicator; Limit Indicator; Input Connector - Mackie SRM350 2-WAY User Manual

Follow the Quick Start guide on page 6
for setting the LEVEL control. For most ap-
plications, it will be in the NORMAL
position (12 o'clock) . If you have a particu-
larly high line-level signal connected to the
SRM350, you may need to turn the control
down to the 9 o'clock position. If you have
a low line-level or mic-level signal con-
nected, you may need to turn the LEVEL
control up to the 3 o'clock position.

MIC/LINE Switch

Leave this switch out when connecting a
line-level signal to the INPUT connector
(from a mixer, graphic EQ, or other line-
level signal source).
Push this switch in when connecting a
microphone to the INPUT connector. Since
a microphone produces a much smaller sig-
nal than a line-level signal, this provides an
additional 40 dB of gain to boost the micro-
phone signal to a line level.

SIGNAL Indicator

This LED illuminates whenever there is
a signal present at the INPUT connector on
the rear panel. It senses the signal just after
the LEVEL control, so if the LEVEL control
is turned down, the SIGNAL indicator
won't light.

LIMIT Indicator

When the signal levels at the amplifier
outputs approach clipping, a soft limiting
circuit is activated that reduces the input
signal. The LIMIT LED lights whenever the
limit circuit is active.
It's okay for the LIMIT indicator to blink
occasionally, but if it blinks frequently or
continuously, either turn down the signal
level at the mixer or other signal source, or
turn down the SRM350's LEVEL control.
Wear hearing protection if
you are close to the
SRM350 playing at high
levels.

INPUT Connector

This is a combination female XLR-type
and 1/4˝ TRS connector that accepts a bal-
anced or unbalanced mic- or line-level signal.

THRU Connector

This is a male XLR-type connector that
can be used to daisy-chain the input signal
to another speaker.
The signal at this point is after the MIC/
LINE switch but before the LEVEL control.
If you have a microphone connected to the
first SRM350 and you have the MIC/LINE
switch pushed in, the signal at the THRU
jack is boosted 40 dB to a line-level, so leave
the MIC/LINE switch out on the next
SRM350.
