not likely to be walked on or pinched by items placed upon or against
them, paying particular attention to wall receptacles and the point
where they exit from the amplifier.
Object and Liquid Entry: The amplifier should not be exposed to
dripping or splashing and objects filled with liquids, such as vases or
plants, should not be placed on top of or next to the amplifier. Care
should be taken so that objects do not fall and liquids are not spilled
into the enclosure through its ventilation openings.

Introduction
Congratulations on your purchase of the Subwoofer Amplifier! Your
subwoofer amplifier is the result of many years of research and de-
velopment dedicated to producing powerful, accurate bass in home
audio systems. This manual contains operating procedures and spec-
ifications. We recommend you thoroughly read through the material
contained in this manual before connecting your amplifier. This will
ensure you have an understanding of how to setup and operate your
amplifier for optimum performance.
The SUBA500 subwoofer amplifier is a high performance, class D sub-
woofer amplifier capable of delivering a minimum of 250W/500W of
clean power at 4 ohms. It uses sound processing technology which
allows you to tailor the performance of the subwoofer to better match
the environment in which it is installed. Both amplifiers feature a large
LCD display as well as a turn-and-push controller for DSP configura-
tion. On the front panel there are indicators for power and standby,
clipping and signal presence.

SUBA 500 INSTALLATION MANUAL
Installing Rack Mount Ears
If you plan to install your sub-
woofer amplifier into a standard
19-inch rack, you must install the
supplied rack ears.
Using the three screws, attach
the supplied rack ears to the sub-
woofer amplifier. If required, the 4
feet on the bottom of the ampli-
fier can also be removed at this
time by unscrewing the mounting
screws located in the center of each foot.
Due to the weight of the subwoofer amplifier, it is
recommended that rear supports be secured
to the rear rack rails. Hardware to do this
is not supplied with the amplifier and is
specific to the type and depth of rack
you are using.
Subwoofer Amplifier Controls and Setup
FRONT PANEL
1. Power Switch: Turns the amplifier on or o. Amplifier must be on
for the trigger or auto sense modes to operate.
2. 16 Character x 2-row Liquid Crystal Display: Shows the amplifi-
er’s status, menus and settings and works in conjunction with the
turn and push navigation controls and the remote control.
3. Programming Navigation Control: Used to scroll through the
display menus, change settings and program the DSP controller.
4. Optional Rack Ears: Two rack mount ears are provided for a 19-
inch rack mounting.
CAUTION! The subwoofer amplifier
is convection cooled and does not
use a fan. For this reason, ensure
there is adequate ventilation above
and below the subwoofer amplifier
when rack mounted. Avoid placing
heat generating equipment below
it in the rack. If the subwoofer
amplifier does not receive enough
ventilation, it may overheat and
switch to standby mode.

Remote Control
The remote control duplicates the functions of the programming navi-
gation control knob on the front of the subwoofer amplifier, plus adds
some additional functions such as power on/o, mute on/o, and one
button selection of the six EQs. In a typical home theater installation
however, the remote will most likely NOT be used, as the subwoofer
amplifier will be configured to a specific subwoofer and room place-
ment, and controlled by the main processor or receiver.
