RM-12
Powered Subwoofer
This powered subwoofer leaves nothing to be
desired. The RM-12 uses a robust, 500 watt, black
anodized aluminum woofer, driven by a powerful
A/B amplifier built exclusively for this cabinet and
driver array.
The RM-12 sounds fantastic with all TruAudio
architectural speakers, making combining different
models in an AV system simple. Additional speak-
ers can be added to a system with the confidence
that the speakers will remain balanced. With over 2
years of engineering and testing, the RM-12 com-
pletes the TruAudio theater package.
The RM-12 includes: Subwoofer cabinet and grill,
power cord, instruction manual and (4) heavy-duty
plastic feet attached to the bottom of the cabinet.
CAUTION: DO NOT OPEN THE SUBWOOFER. THIS
WILL VOID THE WARRANTY.
To reduce the risk of electrical shock and fire, do not
remove the amplifier panel from the back of the
cabinet or the subwoofer from the front of the
cabinet. There are NO fuses or serviceable parts.
All service to this product MUST be done by a
TruAudio Authorized repair center.
Before installing, please read the following
instructions:
• Always turn off the power of your
receiver/preamp and the powered subwoofer
• When turning your amplifier/receiver on, make
sure your volume is turned all the way down
• Never expose the subwoofer to excessive cold,
heat, humidity, or direct sunlight
• This device should never be used in, on or near
water due to risk of fatal shock
• DO NOT attempt to open or dismantle this
subwoofer
• The subwoofer should always have plenty of air
flow to reduce the chance of over heating

NOTES ABOUT HUM
While this amplier has been designed to minimize
the possibility of hum in the subwoofer system, it is
still possible that a hum may occur in rare
circumstances. Safety grounding can create a path
for small amounts of 60 Hz energy to travel through
the line-level audio system. While not
dangerous, this energy can cause difculty with the
subwoofer auto signal sensing circuit, and will
interfere with the quiet enjoyment of your system.
The rst course of action should be trying to make
sure that all of the audio components are connected
to either the same electrical outlet, or at least into
the same circuit branch. Next, cable TV systems are
notoriously the culprit, so be sure to try disconnect-
ing all coaxial feeds that are connected to the
system. If this solves the problem, install a coaxial
line isolator and reconnect the system. Worst case,
a line-level audio isolator/transformer connected to
the line-in of the subwoofer amplier can usually
solve the problem.
Cleaning the Subwoofer
All RM series subwoofers feature lightly textured,
durable paint nish. When needed, we suggest
cleaning with a damp cloth with water only. Do not
use any kind of abrasive cleaners or detergents.
