SUBA 500 INSTALLATION MANUAL
Ventilation: The amplifier should be situated so that its location or
position does not interfere with its proper ventilation. The amplifier
should not be situated on a bed, sofa, rug or similar surface that may
block the ventilation openings, nor should it be placed in a built-in
installation such as a bookcase or cabinet that may impede the flow of
air through the ventilation openings.
Power Source: The amplifier should only be connected to a power
supply of the type described in this instruction manual or as marked
on the amplifier. Precautions should be taken so that the grounding or
polarization means of the amplifier are not defeated.
Power Cords: Power supply cords should be routed so that they are
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.
Damage Requiring Service: This amplifier should be serviced by a
qualified technician when:
• The power supply cord has been damaged; or
• Objects have fallen or liquid has been spilled into the amplifier; or
• The amplifier does not appear to function normally or exhibits a
marked change in performance; or
• The amplifier has been dropped or the enclosure is damaged.
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.

SUBA 500 INSTALLATION MANUAL
REAR PANEL
1. A/B. Inputs: For receiving line-level signal of right channel, or LFE
signal, from a source.
2. Ground post
3. 12V Trigger Input: For trigger-
ing the power on/o from oth-
er devices such as processors
or receivers that have a 12V
trigger output. 6V minimum
required for triggering.
4. Service: For uploading new firmware or updates.
5. 5-way Binding Posts: Connect your subwoofer here. Minimum
impedance of the load is 4 Ohms.
6. Voltage Selector Switch: The
subwoofer amplifier can be
used on 110~120V (60Hz) or
220~240V (50 Hz) line voltage.
To change the operating line
voltage, turn the power o
using the power switch and
unplug the power cord. Re-
move the plastic cover screws
and the plastic cover over the voltage selector located on the rear
of the subwoofer amplifier. Set the switch to the correct position
for the line voltage in your country. Replace the plastic cover and
screws over the voltage selector switch.
7. Power Cord Receptacle: The
supplied power cord needs to
be connected to this recepta-
cle in order for the Subwoofer
Amplifier to work properly.
8. Fuse Holder: This is the pow-
er fuse access. Use a GDA type,
5A 120V or 2.5A 240V fuse.
9. Removable Feet: The am-
plifier feet can be removed
as required for rack mount
installation.
NOTE: Once in trigger mode, the
amplifier cannot be turned on
without a 12V trigger signal. To
disable the 12V trigger, press and
hold the navigation control knob.
The power switch must be in the
ON position. The trigger mode will
be turned o and the amplifier will
power on.
NOTE: If required, remove the IEC
line cord and replace with an IEC
AC cable that matches the AC wall
socket, this should be a 10A rated
cable. When the voltage selector
switch is changed, the fuse must
also be changed to continue to
provide protection to the amplifier.
WARNING! Make certain that you
are using the proper power cord
and voltage selection for the type
of AC power supplied in your coun-
try.
WARNING! In the event the fuse
must be replaced, the replacement
fuse must match exactly the origi-
nal fuse value. If the replacement
fuse is not of the same value, dam-
age to the Subwoofer Amplifier
may result.
CAUTION! Before replacing the
fuse, disconnect the power cord
from the power receptacle.

NOTE: Speaker-level inputs are not used in this system.
LCD Display Screens / Functions
Normally, the LCD display will show the status for a number of settings
as well as the volume level and a flashing output level bar display. The
“normal” display is shown below.
Navigation through the function menus and settings are done via the
programing navigation knob on the front of the subwoofer amplifi-
er. By pressing the programming navigation knob, the amplifier will
switch to the setting mode, and the first screen to appear will be the
“Subsonic Frequency” display, by pressing this knob again it will run
through the dierent function screens. To select a new option for a
setting, turn the knob le. The active option will have an asterisk next
to it.
Once you have configured all the settings for your amplifier, you can
save them by using the “Memory Store” screen. This way, if the settings
are accidently changed, you can always recall your saved settings. You
can also revert to the factory default settings by recalling “Default” in
the “Memory Recall” function.

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.
