Introduction
Congratulations and thank you for purchasing the SUBA150 class D
amplifier. This amplifier is designed as a stand alone compact ampli-
fier that allows custom home installation to have a powerful high ei-
ciency amplifications while fitting in small places. The SUBA150 comes
with a set of standard ears that allow the user to install it in a standard
single rack mount. Whether you are looking to power a subwoofer or a
tactile transducer, the SUBA150 is guaranteed to deliver.
The SUBA150 is powered by a switching regulated power supply PWM.
It delivers a steady and regulated output, delivering a linear amplifi-
cation to your load. Only through linear amplification do you get the
chance to deliver accuracy in amplifications.
The amplifier possesses an eicient switching power supply with
stability at 8 and 4 ohms. These amplifiers will deliver clean accurate
sound with massive damping factor.

Crossover Setting
Listed below are crossover settings in clock-like images. Each setting
shows the frequency response, 3dB down (half level)and system rec-
ommendation for each setting.
Driving A Subwoofer
If you are using the SubA150
to drive a subwoofer, then you
will need to set the crossover
below 100Hz. If you have a large
subwoofer such as 12” or 15” or
even 18”, then you will have a
great response with the cross-
over set to 12 o’clock setting or
minimum setting. For use with
a 10” or 8” subwoofer, you will
find 12 o’clock and 2 o’clock set-
ting to be the best range.
SUBA150 Phase Setting
If you are using the SubA150 to power a subwoofer, you will need to
set the time of arrival of your subwoofer frequencies with that of your
tower speakers. To do that with high accuracy, you will need to have
an SPL meter. There are many suppliers with such device. RadioShack
has one that works just fine. To set the phase, you will need to send a
continuous tone signal through the front speakers and the subwoofer
at the same time, rotate the phase to zero setting and place the me-
ter in the listening position. While the system is playing white noise
or 50-Hz tone, have someone read the meter. Then, rotate the phase
knob until the meter reads the highest reading. This will conclude the
setting. Document the position of your optimum phase and save it for
future references.
Important Safety Instructions
WARNING: To reduce the risk of fire or electric shock, do not expose
this apparatus to rain or moisture.
• Read these instructions.
• Keep these instructions.
• Heed all warnings.
• Follow all instructions.
• Do not use this apparatus near water.
• Clean only with dry cloth.
• Do not block any ventilation openings. Install in accordance with
the manufacturer’s instructions.
• Do not install near any heat sources such as radiators, heat regis-
ters, stoves, or other apparatus (including amplifiers) that produce
heat.
• Do not defeat the safety purpose of the polarized or grounding-type
plug. A polarized plug has two blades with one wider than the oth-
er. A grounding type plug has two blades and a third grounding
Please use this setting if con-
necting to a tactile transducer,
large subwoofer and large front
speakers.
Please use this setting if con-
necting to a tactile transducer, a
large subwoofer and small front
speakers.
Please use this setting if con-
necting to a small subwoofer
and small speakers.

prong. The wide blade or the third prong are provided for your
safety. If the provided plug does not fit into your outlet, consult an
electrician for replacement of the obsolete outlet.
• Protect the power cord from being walked on or pinched particu-
larly at plugs, convenience receptacles, and the point where they
exit from the apparatus.
• Only use attachments/accessories specified by the manufacturer.
• Use only with the cart, stand, tripod, bracket, or table specified by
the manufacturer, or sold with the apparatus. When a cart is used,
use caution when moving the cart/apparatus combination to avoid
injury from tip-over.
• Unplug this apparatus during lightning storms or when unused for
long periods of time.
• Refer all servicing to qualified service personnel. Servicing is re-
quired when the apparatus has been damaged in any way, such as
power-supply cord or plug is damaged, liquid has been spilled or
objects have fallen into the apparatus, the apparatus has been ex-
posed to rain or moisture, does not operate normally, or has been
dropped.
• The MAINS plug or an appliance coupler is used as the disconnect
device, so the disconnect device shall remain readily operable.
• This apparatus has been designed with Class-II construction and
must be connected to a mains socket outlet with a protective
earthing connection (the third grounding prong).
The lightning flash with arrowhead symbol, within an equi-
lateral triangle, is intended to alert the user to the presence
of uninsulated dangerous voltage within the product’s en-

The exclamation point within an equilateral triangle is in-
tended to alert the user to the presence of important operat-
ing and maintenance (servicing) instructions in the literature
accompanying the appliance.
