high quality amplifier to operate a subwoofer speaker system

• Mono Class AB output stage for solid, well dened output

• Manual, auto, or triggered on/off modes for integration into any automated system

• Selectable bass boost

• Draws less than 1 watt in stand-by mode

• Heavy-duty steel chassis with brushed aluminum faceplate

• Adjustable phase, gain, and crossover

• Pop-out adjustment knobs keep settings from being disturbed easily

• Switchable 120/240V input voltage

INSTALLATION:

The SA230 is designed to provide high delity subwoofer amplication and is tailored for home audio and home theater audio
systems. It is not recommended for use in DJ, pro sound, or other high-duty-cycle applications. For home audio systems, use
the unit as it comes out of the box. Care should be taken to leave some room for air circulation above the amplier. Stacked
components that utilize rubber or plastic feet should provide adequate clearance in most situations.

NOTE: The SA230 features an adjustable bass boost control that is preset for a 9 dB boost @ 40 Hz, which optimizes the

Section 7.

FRONT PANEL:

1. Power Switch / Indicator LED

Front panel pushbutton power switch turns the amplier on
and off. When the indicator LED is lit dimly, the amplier is
in standby mode. When the LED is lit brightly, the amplier
is fully active.

3. Frequency

Adjusts the low-pass crossover frequency from 80 Hz to
180 Hz. When using the Left/Right inputs, this adjustment
will allow you to properly integrate the subwoofer with the
satellite or main speakers. It is recommended to experiment
with different settings until the smoothest transition between

2. Phase

subwoofer and speakers is achieved.
Adjustable phase compensation from 0 to 180 degrees.
Corrects phase anomalies that result from differing listening
distances between the subwoofer and main speakers, which
can cause poor acoustic summation around the crossover
point. In most situations the control knob should be left at 0
degrees, but for the advanced user it can be set either by
ear or with the aid of measurement instruments.

4. Gain

Sets the overall level of the amplier, used to match the output

of the subwoofer to the rest of the speakers in the system. If

the source output has a variable control, we recommend that

the user spend a moment or two determining the best balance

between the two controls. When a balance is found between

low noise, linear level control, and sufcient level to drive the

amp to the required output, the gain knob can be considered

to be the “volume control” for the subwoofer system.
