FUNCTIONS
6. Remote Bass Boost Control
This control adjusts the Bass Boost gain for the amplifier’s speaker output (0~ +12dB)
✽Packed product can be different from the photograph.
7. SPEAKER Terminals
As shown in the wiring diagrams, be sure to observe speaker polarity through the system
and speaker impedance. This specially tooled terminal is designed to accommodate p to
10 gauge speaker wire.
8. FUSES
For convenience all ATOM Series amplifiers utilize common automotive ATC type fuses.
For continued protection in the event that a fuse blows, replace the fuse only with the same
value.
9. +BATT (Power Input Connection)
This terminal is the main power input for the amplifier and must be connected directly to
the positive (+) terminal of the car battery.
10. Remote (Remote Input Connection)
All atom Series amplifiers can be turned on by applying 12 volts to this terminal. This can
be found on the rear of the source unit in the form of an electric antenna output, or a
remote output.
If this is not available yo can wire to the ACC position on the key. An 18 gauge wire is
sufficient to run the REMOTE.
11. GND (Ground Input Connection)
A good quality ground is required for your ATOM Series amplifier to operate at peak
performance.
A short length of cable the same gauge as your power cable should be used to attached
the ground terminal directly to the chassis of the vehicle.
12. Power Indicator
The GREEN when the power is on.

13. Gain adjustment control
The input level can be adjusted with this control. Turn it in the clockwise direction when the
output level of the car audio unit seems low.
14. Sub Sonic Filter
Variable subsonic filter (20Hz ~50Hz)
The subsonic filter will roll off all of the unwanted frequencies below 20HZ ~50Hz.
This will allow the amplifier to use that wasted power on the audible bandwidth.
15. Low pass Filter
ATOM amplifier has an internal variable low pass filter. It can be set from 50 p to 500Hz.
16. Bass boost level control
Turn this control to boost the frequencies around 45Hz to a maximum of 12dB.
