SRM350v3/SRM450v3 Loudspeaker: Rear Panel Features
1. Power Connection
This is a standard 3-prong IEC power connector.
Connect the detachable power cord (included in
the packaging with the loudspeaker) to the power
receptacle, and plug the other end of the power
cord into an AC outlet.
Make sure that the AC power is matched to
the AC power indicated on the rear panel
(below the IEC receptacle).
Disconnecting the plug’s ground pin is
dangerous. Don’t do it!
2. Power Switch
Press the top of this rocker switch inwards to turn
on the loudspeaker. The front panel LED will glow
with happiness...or at least it will if the loudspeaker is
plugged into a suitable live AC mains supply and the
main LED switch [10] is disengaged.
Press the bottom of this rocker switch inwards to turn
off the loudspeaker.
As a general guide, SRMv3 loudspeakers
should be turned on last, after any mixer
or other signal source. As such, they should
also be turned off first. This will reduce the possibility
of any turn-on or turn-off thumps and other noises
generated by any upstream equipment from coming
out of the speakers.
3. XLR and 1/4" Combo Inputs
Both channels feature 1/4" Wide-Z
™
inputs with
combo jacks that may accept balanced/unbalanced XLR
and 1/4" connections. The gain range of the Wide-Z
inputs may handle anything from an instrument or mic
level to a line-level signal such as from a mixer. Simply
connect an XLR, TRS or TS connector into the channel
and adjust the gain accordingly.
Please be aware of the position of the gain
knob [4].
NEVER connect the output of an amplifier
directly to the input of the loudspeaker.
This could damage the input circuitry
of the active loudspeaker.
XLR connectors are wired as follows, according to
standards specified by the AES (Audio Engineering
Society):
Balanced XLR Input Connector
Pin 1 – Shield (ground)
Pin 2 – Positive (+ or hot)
Pin 3 – Negative (– or cold)
To connect balanced lines to these inputs, use a
1/4" Tip-Ring-Sleeve (TRS) plug. “TRS” stands for
Tip-Ring-Sleeve, the three connection points
available on a stereo 1/4" or balanced phone jack
or plug. TRS jacks and plugs are used for balanced
signals and stereo headphones and are wired as follows
according to standards specified by the AES (Audio
Engineering Society):
