3. LPF (Low Pass Filter) Control
This filter controls low pass of frequencies and is adjustable from 50Hz through 250Hz to eliminate unwanted
high frequencies.
4. BASS EQ Control
This equalization circuit is used to enhance the low frequency response of the vehicle’s interior. With up to
18dB of boost centered at 45Hz, the BASS EQ can be adjusted to meet your own personal taste.
5. SUB SONIC Control
This control is continuously adjustable from 10Hz through 50Hz at 12dB per octave to provide an extra level of
speaker protection from bass robbing power at unheard frequencies.
6. GAIN Control
This control is used to match the input sensitivity of the amplifier to the particular source unit that you are
using up to 10 volts.
7. AUX Input Jack
This 1/8-inch (3.5mm) mini jack can be used to accept an MP3, iPOD or smartphone as the source unit from
that device's headphone (3.5mm) output.
8. HIGH/LOW INPUT
Use this Low Level 4-pin Molex style input is where the wiring harness plugs in for the Low Level input that
connects to source units with RCA line level outputs. A source unit with a minimum input of 250mV is required
for proper operation. However, this input can accept levels up to 10Vrms.
9. GND (Ground Input Connection)
A good quality ground is required for your PowerBass Xtreme amplifier to operate at peak performance. A
short length of cable the same gauge as your power cable should be used to attach the ground terminal
directly to the chassis of the vehicle. Make sure that all of the paint is sanded or scraped away to ensure a
quality ground connection.
NOTE: If installing in a boat, UTV or motorcycle make sure your ground wire is connected to the
negative ( - ) terminal of the battery.
10. REM (Remote Input Connection)
All PowerBass Xtreme 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 a remote output. If this is not available you can wire to the ACC
position on the key. An 18 gauge wire is sufficient to run the REMOTE.
