DRM12A Loudspeaker: Rear Panel Features
1. AC In Jack
There is no power switch on the DRM12A. When
connected to the AC mains, the loudspeaker will be
fully operational.
Connect the supplied AC mains cord to the AC
IN Neutrik PowerCon® jack on the rear panel
of the DRM12A. The PowerCon® system utilizes
a locking connector. To lock, twist 1/4 turn clockwise
after fully inserting it into the AC IN receptacle.
Then connect the other end of the cable to the AC
mains supply receptacle.
Ensure that the AC mains voltage matches
the voltage rating listed on the DRM12A
below the AC IN connector.
Ensure that the AC power supply has
a properly grounded safety ground.
Failure to follow this warning could cause
equipment damage, serious personal injury, or even
death.
The supplied AC in plug may not be
appropriate for local AC mains receptacles.
If not, have a qualified electrician remove
the existing AC mains plug and install a plug
appropriate for the AC mains supply receptacle
and following all local codes.
If an extension cord is used for the AC mains,
use only a cord with the appropriate wire size
and current rating for the required current
draw and extension cord length.
As a general guide, powered speakers
should be powered up last, after the mixer
and other sources. They should also
be the first things turned off. This will reduce
the possibility of any turn-on, or turn-off thumps
in the loudspeakers.
2. AC Thru Jack
The Neutrik PowerCon® AC IN and AC THRU
connectors are wired in parallel to provide
an AC IN inlet and outlet on each DRM12A.
An AC Thru cable is included with the DRM12A.
The white connector mates with the AC Thru outlet,
while the blue connector mates with the AC In inlet.
Therefore, to loop the AC In from enclosure to
enclosure, connect the included AC In jumper cable
from the AC Thru output of one DRM12A to the AC In
input of the next DRM12A as shown on page 6.
Up to four DRM12As may be looped in this fashion
from a single 20A service.
The maximum, continuous load from
the first DRM12A Loop output must not
exceed 6A at 100–120V and 3A at 220–240V.
3. AC Thru Circuit Breaker
The AC Thru circuit breaker protects the AC Thru
outlet. If the continuous load connected to the AC Thru
outlet exceeds the rated load, the circuit breaker will
trip. For this situation, reduce the connected load
and then manually reset the circuit breaker.
As is the case with the AC Thru,
the maximum, continuous load from
the first DRM12A Thru output must
not exceed 6A at 100–120V and 3A at 220–240V.
Yes, there are quite a few ‘Very Important’

review them carefully, because they are
indeed ‘Very Important’!
