4. How this crossover is used The Planet Audio EC20B 3 way elec tronic crossover is a high fidelity signal processor that allows you to custom ize the low level output of your input source e g a car radio so that the signal can be applied to an amplifier or amplifiers as a part of a 2 way or 3 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 Front Rear and Sub woofer LOW LEVEL outputs via RCA connectors Product architecture This crossover accepts the low level RCA type input signal from the follow ing types of head unit outputs a 2 channel L R only b Front L R and Rear L R c Front L R Rear L R and Subwoofer channel mono d Front L R Rear L R and Subwoofer channel L R By making proper switch settings any of these types of head unit outputs can be utilized as a signal source from which the EC20B can derive a few different kinds of system configurations Exam ples of these are shown in diagrams in this manual Important features The EC20B incorporates several key fea tures which greatly expand the ways in which it can be used in a mobile audio system Parallel input selection The EC20B is optimized for head units which provide outputs for Front L R Rear L R and Subwoofer L R channels But what if your head unit only provides a single pair of stereo L R outp
