REAR PANEL DESCRIPTION
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 de-
termine which way sounds best for your
application. It is especially useful when lis-
tening at lower volumes, as it highlights the
bass like a Loudness switch, in addition to
boosting the highs.
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 SRM350 in-
corporates 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 for a microphone,
so you should use a
dynamic mic, or use a
condensor type if it has its
own battery power.
The SRM350 has several connectors,
controls, and indicators that you should
understand.
IEC Socket
This is where you connect the supplied
AC linecord to provide AC power to the
SRM350’s built-in power amplifiers. Plug
the linecord into an AC socket properly
configured for your particular model.
Note:
If you happen to lose the AC line-
cord, replacements are readily available at
any office or computer supply store. Always
use a three-pin plug with a ground pin.
POWER Switch
Switch up to turn the SRM350 on, and
switch down to turn it off. Make sure the
LEVEL
control is down before you turn it on.
POWER Indicator
When the
POWER
switch is turned on,
and the linecord is connected to an active
AC Mains supply, this indicator, located
just above the
POWER
switch, glows to let
you know that you’re ready to rock and
roll. The cool blue LED on the front of the
speaker works in the same way.
