How A Crossover Is Used
-----------------------
The Planet Audio EC20B three-way electronic crossover is a
high-fidelity signal processor that allows you to customize the
low level output of your input source (a car radio), so that the
signal can be applied to an amplifier or amplifiers as a part of
a two-way or three-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 subwoofer
low level outputs via RCA connectors.
Parallel Input Selection
------------------------
The EC20B is optimized for head units which provide outputs for
Front (UR), Rear (UR), and Subwoofer (UR) channels. But what if
your head unit only provides a single pair of stereo (UR)
outputs? By setting the Parallel Input selector control to Out,
the signal applied to the Front (UR) EC20B inputs will also be
routed to the Rear channel. This eliminates the need for external
Y-adaptors, which can sometimes add noise to the system. Now you
can provide custom processing to the Rear channel independent of
the settings you apply to the front.
Specifications
--------------

* Crossover slope, front and rear: selectable 6d8/octave or
18d8/octave

Front Channel Crossover Multiplier
----------------------------------
By providing a way for you to select a frequency from either a
Mids/Highs range or a Tweeter range for the Front channel
crossover, we give you the choice to use this crossover in
different applications. For example, you can use the Front
channel as a stereo Tweeter channel by setting the Crossover
Frequency Multiplier to the higher 800Hz-8kHz range, and Rear
channel can serve as the Mids/Highs channel, for a three-way
stereo system. Or you could create a four-channel system, with
Front and Rear channels reproducing the Mids/Highs.
Subwoofer Input Mix Option
--------------------------
Many head units also lack a subwoofer channel output. In this
situation, by setting the Sub Input control to Mix, the EC20B sub
channel controls will be delivered a mix of L Front/Rear to the
Subwoofer Left Channel and a mix of the R Front Rear to the
Subwoofer Right channel. This eliminates the need for external Y
adaptors and mixer devices.

Input, Output, Remote, And Power Connections
--------------------------------------------
* Power LED
* Front And Rear L/R Inputs: Connect the outputs of your head
units to these connections and be sure to place the Parallel
Input selector in the In position.
* Parallel Input Selector: If your audio source only has one pair
of RCA inputs, placing this switch in the Out position allows the
signal source connected to the front inputs to also be routed to
the rear channel of the EC20B.
* Sub Input Source Selector: If your audio source lacks a
subwoofer channel output, placing this switch in the Mix position
will apply a mix of the front and rear channel of each of the
left and right inputs to the EC20B sub channel input.
* Subwoofer Channel Input: Connect the subwoofer channel of your
head unit to these connectors and place the Sub Input selector in
the Direct position. If no sub channel outputs are available, see
"Sub Input Source," above.
* +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 32 Hz and 250Hz.
* Fuse Connector: Use only fuse with 3A rating.
* Front And Rear UR Outputs
* Subwoofer L/R Outputs
* Remote Level Control Connector

Front And Rear Channel Controls
-------------------------------
* High Pass Crossover: Use this control to set the lowest
frequency which will pass through the Front (or Rear) Channel of
your system.
* High Pass Crossover Frequency Multiplier (front channel only):
This selector sets the frequency range for the high pass
crossover. Choose the x1 position for 40Hz-400Hz range, or x20
for 800Hz-8kHz range.
* Crossover Slope: Crossover slope determines how rapidly the
drop-off in sound level, measured in decibels/octave, occurs at
the frequency selected by the crossover. One octave is equal to
one-half of the currently selected frequency. For example, if you
set the crossover to 80Hz and the slope to 18dB, the level at
40Hz to be 18dB lower than at 80Hz.
* Output Level Control: This control allows you to independently
set the output level of the channel.
