SUBWOOFER AMPLIFIER

Model: SA1000 User Manual

Thank you for purchasing the Dayton Audio® SA1000 subwoofer amplifier, one of the most versatile and powerful subwoofer amplifiers
available. The tabletop or rack-mountable design is perfect for high-end home theater installations or DIY subwoofer projects. The SA1000
has the power to drive even the most power-hungry subwoofer systems.

FEATURES:

• Patented tracking downconverter power supply

for high efficiency

• Class AB output stage for clean, controlled output

• Low frequency parametric EQ allows you to boost or

cut to custom-tailor the sound

• Advanced soft clip circuitry improves headroom and

protects woofers

• Manual, auto, or triggered on/off for integration into

any automated system

• Switchable subsonic and bass boost filters

• High pass output for looping signal back into

distributed audio systems

• Can be easily converted between rack-mount and

tabletop configurations

• Heavy-duty steel chassis with brushed

aluminum faceplate

• Adjustable phase, gain, crossover, and parametric EQ

• Pop-out adjustment knobs keep settings from being

easily disturbed

• Switchable 110/220V input voltage

INSTALLATION:

The SA1000 is designed to provide high fidelity subwoofer amplification and is tailored for home audio, home theater, and studio
environments.

It is not recommended for use in DJ, pro-sound, or other high-duty-cycle applications. For home audio tabletop applications, use
the unit as it comes out of the box with the rubber feet and without the rack ears. In a custom home theater or studio where rack
mounting is available, simply remove the rubber feet and attach the included rack ears. The amplifier runs cool thanks to its high
efficiency, but 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. 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.

3. Frequency

Adjusts the low-pass crossover frequency from 30 Hz to

200 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. Phase

Adjustable phase compensation from 0 to 180 degrees.

Helps the user correct improper phasing of the main speak­ers or differing listening distances between the subwoofer
and mains, which can cause a poor acoustic summation
around the crossover point. In most situations the 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.

5. EQ

The EQ adjustment knobs enable the user to custom-tailor

one band of parametric equalization for their subwoofer,
which can be used to add boost to the low-end of the re­sponse, or can be used to cut out an excessively loud room
resonance. The freq. knob selects the frequency for the filter,
the bandwidth knob selects how wide or narrow the filter is
(the higher the bandwidth, the broader the effect), and the
level knob can be used to add up to 6dB of boost or 14 dB
of cut.
