How An Equalizer Is Used

The Planet Audio PEQ10 parametric equalizer is a high-fidelity signal processor/preamplifier that allows you to control the relative levels within the audible frequency spectrum of a stereophonic system. It is intended for use in a car audio system which includes amplifiers in a signal path after the equalizer, and provides front, rear, and subwoofer low level outputs via RCA connectors.

Front Panel Controls And Key Features

Master Volume Control: Use this to adjust the overall output volume level.
Fader: Use this control to balance the sound level between front and rear speakers as desired.
Auxiliary Input Selector: This button permits you to select the equalizer input source. The unit features separate rear RCA inputs for CD/DVD players and your choice of an AUX input.
Subwoofer Frequency: Use this knob to set the crossover frequency for the subwoofer output channel (i.e. it is a low pass filter)
Subwoofer Gain: This control permits you to increase or decrease the output level of the subwoofer channels.
Boost/Cut Controls: Each of these controls represent a range of frequencies surrounding a center frequency to cover the audio spectrum from subwoofer frequencies to treble frequencies. Adjust these controls to suit your taste and listening environment. Each center frequency can be adjusted +/- 12 dB.
