DRM Loudspeakers: Rear Panel Features continued...
To connect unbalanced lines to these inputs,
use a 1/4" mono (TS) phone plug, wired as follows:
1/4" TS Unbalanced Mono Wiring:
Sleeve = Shield
Tip = Hot (+)
NEVER connect the output of an amplifier
directly to a DRM’s input jack. This could
damage the input circuitry!
4. Gain [Ch. 1 and 2]
The gain knobs adjust the input sensitivity
of the mic/line inputs. This allows signals from
the outside world to be adjusted to run through
each channel at optimal internal operating levels.
There is – dB of gain with the knob fully down
(off), ramping up to +50 dB of gain fully up (max).
If connecting mixer outputs to loudspeaker
inputs, set the gain knob to 10:00 [“U”]
for optimal sound and performance.
5. Direct Out [Ch. 1 and 2]
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 DRM
loudspeakers together off the same signal source(s).
They are 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 8 to learn more about daisy-chaining
DRM loudspeakers.

6. 1/8" Input [Ch. 3/4]
This input may accept a stereo 1/8" line-level signal
from a phone, tablet, MP3 player, or other signal
source.
NEVER connect the output of an amplifier
directly to this input jack. This could damage
the input circuitry.
7. Gain [Ch. 3/4]
This gain knob adjusts the input sensitivity
of the 1/8" stereo input. This allows signals from
the outside world to be adjusted to run at optimal
internal operating levels. It ranges from off (knob
fully down) up to max (knob fully up).
8. Mix Out
This is a male XLR-type connector that produces
the post-DSP mix – after voicing mode and EQ, but
before the alignment delay – from all three input jacks
(with Ch. 3/4 mono-summed). Use it to daisy-chain
several DRM loudspeakers together off the same
signal source(s).
It is wired the same as the direct outputs as seen
to the left.
9. LCD Display
This modern, high-resolution, all-color TFT LCD
Display is one of the most vital features of the DRM
loudspeaker. It displays loudspeaker information
including (but not limited to) levels, EQ, selected
voicing, 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.
10. Speaker Control Knob
This push-button rotary encoder allows you to access
functions such as channel and master level control
and metering, application specific voicings & EQ, setup
functions, product information and much more!
