One of the most technologically
advanced subwoofer amplifiers on the market! This new subwoofer amplifier is
based on state-of-the-art Class G circuit topology that combines the proven high
power, high fidelity characteristics of a Class AB amplifier with a patented
tracking down converter power supply to achieve an operating efficiency up to
86%. You get the efficiency of a Class D amplifier without compromising audio
quality and reliability. The class AB output stage provides the clean and
low-distortion sound that audiophiles demand, without any instability problems
of other high-efficiency amplifier designs. This American designed and
engineered amplifier uses patented circuitry that continuously tracks the input
signal to modulate or control the voltage available to the output stage. This
"tracking" capability delivers the exact amount of power based on demand instead
of constantly keeping it in reserve, so the output stage only draws the amount
of power that is required at any given time. This means less energy is wasted as
heat, and more power is available for the subwoofer driver. Dimensions:
11-15/16" W x 11-15/16" H x 5-1/4" D. Cutout dimensions: 10" W x 10" H.

RCA style jacks that will accept standard line
level inputs from a preamp level source.
They will accept a stereo signal and internally combine it into mono. Both left
and right input jacks must
be connected to the source in order to drive the amplifier to full output.
LFE Direct Input:
RCA jack that will accept a signal from the mono LFE (Low Frequency Effects)
output on a preamp
or receiver that is equipped with a dedicated sub bass output. This input
amplifiers own internal low pass filter circuitry, relying instead on the
provided by the source equipment.
This unit features an IEC grounding type power input connector. The IEC
connector allows the
user to quickly exchange the power cord if it is damaged, or if a longer cord is
desired. The IEC
inlet connector also features an integrated fuse holder that contains the AC
Low Pass, Gain:
Will match the amplifiers input sensitivity to the output of the pre-amp source.
If the source
output has a variable control, we recommend that the user spend a moment or two
the best balance between the two controls. When a balance is found between low
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.
This control is used to establish the highest frequency that the subwoofer will
has a range between 30 and 200 Hz. If your main speakers have good bass
could set the control to a fairly low value at 40, 60, or even 100 Hz.
When the power switch is moved to the on position, the LED will illuminate in
green, and the
amp will be in stand by mode. If a low level signal of about 3 millivolts or
greater is applied to
the input, the light will change color to yellow to indicate that the amplifier
is fully operational
and receiving typical music program. As input signal increases to the onset of
clipping the LED
will turn red, which indicates that the clip limiting circuitry is activated. If
an input signal is not
detected for 10 to 15 minutes, the amp will go back to stand by mode and the LED
back to green.
This two-position (NOR = 0° phase and REV = 180° phase) switch helps to

The HPSA500 Amplifier features a
fully parametric equalizer to help you to achieve the best possible subwoofer
performance. Professional sound engineers have for many years considered the
parametric EQ to be one of the most
accurate, versatile, and high fidelity tools for audio enhancement.
Establishes the specific frequency at which EQ boost or cut may be
applied between18 Hz and 80 Hz.
Determines how narrow or wide the EQ curve will be within a range of 0.1 to 1.0.
If for example
a frequency of 60 Hz were selected along with a Q of 0.1, the frequencies to
either side of 60
Hz would be less affected.
Permits the application of up to 6dB of boost or 14.5dB of cut at the
selected frequency and
