Features
Class A/B MOSFET Power
Supply: This 2-channel amplifier is
from Audiobahn's Class A/B MOSFET series of amplifiers.
Regulated Power Supply:
The MOSFET power supply in this amplifier is pulse width modulated (PWM).
This type of power supply regulates fluctuating voltage from the car's battery
to keep the output power of the amplifier from fluctuating with the input
voltage; this results in consistent power delivery despite input voltage
fluctuations.
High Gloss Chrome-Plated
Finish: This amplifier has a high-gloss
chrome-plated finish on the top and on all sides. A pair of white cotton
gloves is included with the amplifier to prevent finger-print smudges when
handling and mounting the amp.
Digital Voltmeter:
On the top of this amplifier is a digital voltmeter with cobalt blue
illumination. The interior circuit board illuminates as well.
Cooling Fan: There are two
built-in cooling fans on the top of this amplifier, which are activated whenever
the amplifier receives a signal from the remote turn-on lead. If the remote
turn-on lead is connected to your radio, then the cooling fans will run whenever
your radio is turned on. The amplifier will shut down if the internal
temperature reaches 158 degrees F.
Variable Subsonic Filter:
A subsonic (infrasonic) filter allows you to filter out extremely low bass
frequencies that may rob power from frequencies that the system can reprduceo
without distortion. Use of the infrasonic filter allows better amplifier
efficiency and better audible sound. The subsonic filter in this amplifier
is continuously variable from 20Hz to 50Hz.
Soft-Start Circuitry:
The amplifier automatically turns on a few seconds after you turn your vehicle's
ignition switch to ACC or ON. The power indicator on the side of the
amplifier lights when the amplifier is on.
Terminals: The
amp has nickel-plated, heavy-duty set screw terminals.
Protection Circuitry:
- Thermal:
shuts off the amp when the operating temperature is too high
- Input Overload:
shuts off the amp as a result of low voltage or over-voltage
- Short Circuit:
shuts off the amp due to speaker or DC short
Controls
Left Side of Amplifier
- Variable Gain Control:
a rotary control that allows you to match the input sensitivity of the amp
to the particular source unit you are using
- Subsonic Frequency Control:
a rotary control that allows you to filter out unwanted bass frequencies.
The subsonic filter in this amplifier is continuously variable from 20Hz to
50Hz.
- High-pass Frequency Control: a
rotary control that allows you to adjust the frequency of the high-pass
crossover from 50Hz to 750Hz
- Low-pass Frequency
Control: a rotary control that
allows you to adjust the frequency of the low-pass crossover from 50Hz to
120Hz
- Crossover Switch:
lets you select high-pass, low-pass, or full-range operation for the speaker
outputs
- Bass Boost Switch:
lets you select OFF or +18dB
- Subsonic Frequency Switch:
lets you turn the subsonic filter on or off
Inputs
and Outputs
Right Side of the Amplifier
- Line-In:
left and right RCA input jacks

Wiring
Recommendation
Wiring Recommendation:
This amplifier uses two 40-amp fuses, so its fuse rating (80-amps total) exceeds
that of typical 4 gauge wiring kits, which tend to include a 60-amp fuse. For 80-amp
fuse protection, the fuse included with a pre-packaged wiring kit should be
replaced with an 80-amp AGU fuse (sold separately).
