Thank you for purchasing the Dayton Audio

®

 SA230 subwoofer amplifier. Its tabletop design is compatible with many 

other popular electronic devices and multimedia furniture. The SA230 offers its owner the freedom to use a stand-alone, 
high quality amplifier to operate a subwoofer speaker system

FEATURES:

• Low-level, high-level, and LFE inputs
• Mono Class AB output stage for solid, well defined 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 fidelity subwoofer amplification 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 amplifier. Stacked 
components that utilize rubber or plastic feet should provide adequate clearance in most situations.

FRONT PANEL:

1. Power Switch / Indicator LED

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

2. Phase

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. 

3. Frequency

Adjusts the low-pass crossover frequency from 40 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 
subwoofer and speakers is achieved.

4. Gain

Sets the overall level of the amplifier, 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 sufficient level to drive the 
amp to the required output, the gain knob can be considered 
to be the “volume control” for the subwoofer system.
