4. XLR Input
The input channel may accept a balanced mic
signal using an XLR connector. It is 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)
NEVER connect the output of an amplifier
directly to the DRM12A’s input jack.
This could damage the input circuitry!
5. XLR Output
This is a male XLR-type connector that produces
exactly the same signal that is connected to the input
jack located above it. Use it to daisy-chain several
DRM12A loudspeakers together off the same signal
source.
It is wired as follows, according to standards
specified by the AES (Audio Engineering Society):
Balanced XLR Output Connector
Pin 1 – Shield (ground)
Pin 2 – Positive (+ or hot)
Pin 3 – Negative (– or cold)
See page 6 to learn more about daisy-chaining
DRM12A loudspeakers.

6. LCD Display
This modern, high-resolution, all-color TFT LCD
Display is one of the most vital features of the DRM12A
loudspeaker. It displays loudspeaker information
including (but not limited to) levels, array mode,
high-pass filter, EQ and delay settings, lock / unlock
status and other parameters.
The brightness is controllable, but
an overall screen brightness is required
for certain aspects of the set-up options.
7. Speaker Control Knob
This push-button rotary encoder allows you
to access functions such as master level control
and metering, array mode, subwoofer HPF, EQ and
delay settings, product information and much more!
8 and 9. Dual-Angle Pole Cup
The rear pole cup [8] is for use with a single unit on
a pole. It orients the DRM12A downward 10˚ for output
parallel to the floor.
The front pole cup [9] serves two purposes. It angles
the DRM12A downward 30˚ to aim at the audience
below the loudspeaker. It may also be utilized for use
with two DRM12As arrayed on one pole.
