①FREQ(cutofffrequency)control
Cutoff frequency selectable from 40 Hz to 500 Hz.
- Set the LPF/HPF select switch to LPF or HPF according to the typeoff frequency that you want to cutoff.
②LPF(low-passfilter)/HPF(high-passfilter)selectswitch
Switchthesettingsbasedontheconnected speaker.
- Whenafull-rangespeakerisconnected, select HPF or OFF. HPF eliminates low-rangefrequencyandoutputhigh-range frequency.OFFoutputstheentirefrequencyrange.
- Whenalow-rangespeakerorsubwoofer isconnected,selectLPF.
③GAIN(gain)control
Adjusting the gain control helps align the car stereo output to the Pioneer amplifier. The default setting is the NORMAL position. If the output remains slow, even when the car stereovolume is turned up, turn the control to a lower level. If distortion occurs
whenthecarstereovolumeisturnedup, turnthesecontrolstoahigherlevel.
- Incaseofabridgeconnection, setthe gaincontrolsforspeakeroutputsA and Btothesameposition.
- ForusewithanRCAequippedcarstereo (standardoutputof500 mV), settothe NORMALposition. ForusewithanRCA equippedPioneercarstereo, with maximumoutputof4 Vormore, adjustlevel to match that of the carstereo output.
