5. HPF (High Pass Filter) Control/CH 3 and CH 4
This control is continuously adjustable from 15Hz through 250Hz at 12dB per octave and is used in conjunc-
tion with CH3 and CH4 only
6. BASS EQ Control/Subwoofer
This equalization circuit is used to enhance the low frequency response of the vehicles interior. Variable up
to 18dB of boost for the Subwoofer channel centered at 45Hz, the BASS EQ control can be adjusted to meet
your own personal taste.
7. GAIN Control/CH 1 and CH 2
This control is used to match the input sensitivity of the amplifier to the source unit you are using on CH1 and
CH2 inputs.
8. GAIN Control/Subwoofer
This control is used to match the input sensitivity of the amplifier to the source unit you are using on the SUB
INPUT.
9. HPF (High Pass Filter) Control/CH1 and CH 2
This control is continuously adjustable from 15Hz through 250Hz at 12dB per octave and is used in conjunc-
tion with CH1 and CH2 only.
10. SUB INPUT Selector Switch
This button selects the signal source for the SUB channel. When the button is in, the input signal will be sup-
plied from the SUB INPUT RCA. When the button is out, the amplifier will use the signals from CH1 through
CH4 summed.
11. SUB INPUT (RCA) Jacks
These RCA style input jacks are for use with source units that have a dedicated RCA line level SUBWOOFER
outputs. A source unit with a minimum of 0.05 volt is required for proper operation. However, this input will
accept levels up to 6Vrms.
12. REMOTE (Remote Gain Input Connection)
This is the input port for the wired Remote Gain control (included). This allows up to 18dB of volume adjust-
ment and controls the level of the subwoofer channel only.
13. POWER Indicator
This clear LED lights Blue when the power is on and the amplifier is wired correctly.
