Contour; Level; Mic/Line Switch; Signal Indicator - Mackie SRM350v2 Owner's Manual

4. CONTOUR

Pushing in this switch engages a filter that provides 3 dB
of boost to the low and high frequencies (below 100 Hz
and above 12 kHz). This provides a punchy, crisp sound
for most live music applications. You can experiment with
this switch by leaving it out for a while, then pushing it in
to determine which way sounds best for your application.
It is especially useful when listening at lower volumes, as
it highlights the bass like a Loudness switch, in addition to
boosting the highs.

5. LEVEL

This is used to adjust the signal level going into the
built-in power amplifiers, from off up to 45 dB of gain. Since
the SRM350v2 incorporates Mackie's world-class low-noise
mic preamp technology, you can connect either a line-level
or a microphone-level signal to the input, and use this
control to adjust the level correctly.
There is no phantom power provided for a
microphone, so you should use a dynamic
mic, or use a condenser type if it has its own
battery power.
Follow the Quick Start guide on page 6 for setting the
LEVEL control. For most applications, it will be in the
NORMAL position (12 o'clock). If you have a particularly
high line-level signal connected to the SRM350v2, 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 connected,
you may need to turn the LEVEL control up to the
3 o'clock position.

6. 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 signal than a line-level signal, this provides
an additional 40 dB of gain to boost the microphone signal
to a line level.

7. 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.

8. 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 SRM350v2's LEVEL control.
Wear hearing protection if you are close to
the SRM350v2 playing at high levels.

9. INPUT Connector

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

10. 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 SRM350v2 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 SRM350v2.
