How A Crossover Is Used The two-way electronic crossover Planet Audio EC10B is a high-fidelity signal processor that allows customization of the low level output of your input source (such as a car radio), so that the signal can be applied to an amplifier or amplifiers as part of a two-way mobile audio system.
It is intended for use in a car audio system which includes amplifiers in the signal path after the crossover, and provides low level outputs for front, rear, and subwoofer via RCA connectors.
Input, Output, Remote, And Power Connections View larger Input, Output, Remote, And Power Connections Power LED Remote Level Control Connector Left/Right Low Level (RCA) Inputs: If your head unit has low level (RCA) two-channel outputs, connect the outputs of your head units to these connections.
Left/Right High Level (speaker) Inputs: If your head unit lacks low level (RCA) two-channel outputs, connect the outputs of your head units to these connections.
Do not connect both high level and low level inputs to the EC10B.
Left/Right Low Pass (Subwoofer) Outputs Left/Right High Pass (Highs/Mids) Outputs +12V, Ground And Remote Turn-On Terminals: Use this control to select the highest frequency to be sent to the subwoofer channel.
Choose a frequency between 50 Hz and 250Hz.
Fuse Connector: Use only fuse with 3A rating Front And Rear Channel Controls View larger Front And Rear Channel Controls Output Level Control: Use this control to set the output level for the low pass (subwoofer) channel.
Bass Boost Level Control: Use this control to set the amount of bass boost which will be added to this channel.
Low Pass Frequency Control: This control will set the highest frequency which will pass through the low pass (subwoofer) channel of your system.
Output Mode Selector: Use this to select either Mono or Stereo signal output to be delivered to the low pass (subwoofer) outputs.
Phase Selector: This control will let you select the output phase of the low pass (subwoofer) channel for the best time alignment and imaging.
Output Level Control: Use this control to set the output level for the high pass (Highs/Mids) channel.
Low Pass Frequency Control: This control will set the lowest frequency which will pass through the high pass (Mids/Highs) channel of your system.
