Setting the Unit
Cut Off Frequency Control Power Indicator
The power indicator lights when the power is switched on. If the LPF/HPF select switch is set to LPF (or HPF), you can select a cut off frequency from 40 to 120 Hz.
Gain Control
If the sound level is too low, even when the volume of the car stereo used along with this power amplifier is turned up, turn gain control on the front of the power amplifier clockwise. If the sound distorts when the volume is turned up, turn the gain control counter-clockwise.
· When using with an RCA equipped car stereo (standard output of 500 mV), set to the NORMAL position. When using with an RCA equipped Pioneer car stereo with max. output of 4 V or more, adjust level to match the car stereo output level.
Bass Boost Level Control
Bass boost level control can boost the level around the frequency selected by the bass boost frequency control from 0 to 18 dB.
LPF (Low-Pass Filter)/HPF (High-Pass Filter) Select Switch
Set the LPF/HPF select switch as follows according to the type of speaker that is connected to the speaker output connector and the car stereo system: LPF/HPF Select Switch
LPF (left) OFF (center) HPF (right)
Audio frequency range to be output
-- 40 to 120 Hz Full range 40 to 120 Hz --
Speaker Type
Subwoofer Full range Full range
Remarks
Connect a subwoofer.
Bass Boost Frequency Control
You can select a bass boost frequency from 40 to 120 Hz with the bass boost control.
· Bass Boost Level Control and Bass Boost Frequency Control can be adjusted only when the LPF/HPF select switch is set to a position other than HPF.
Use if you want to cut the very-low-frequency range because it is not necessary for the speakers you are using.
