The Planet Audio EC20B three-way electronic crossover is a high-fidelity signal processor designed to allow 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 part of a two-way or three-way mobile audio system. It is intended for use in a car audio system that includes amplifiers in the signal path after the crossover, and provides front, rear, and subwoofer low-level outputs via RCA connectors.

The EC20B is optimized for head units that provide outputs for Front (UR), Rear (UR), and Subwoofer (UR) channels. However, if your head unit only provides a single pair of stereo (UR) outputs, you can set the Parallel Input selector control to "Out," which will route the signal applied to the Front (UR) EC20B inputs to the Rear channel. This eliminates the need for external Y-adaptors, which can sometimes add noise to the system, allowing you to provide custom processing to the Rear channel independent of the settings applied to the front.

The EC20B crossover also provides the ability to select a frequency from either a Mids/Highs range or a Tweeter range for the Front channel crossover, giving you the flexibility 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, while the Rear channel can serve as the Mids/Highs channel for a three-way stereo system. Alternatively, you can create a four-channel system, with Front and Rear channels reproducing the Mids/Highs.

Many head units also lack a dedicated subwoofer channel output. In such cases, by setting the Sub Input control to "Mix," the EC20B sub channel controls will receive a mix of the 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.

The NEW Planet Audio EC20B 3-Way Electronic Crossover with Remote Sub Level Control offers the following key features:

• Continuously Variable Low Pass: 32Hz to 250Hz
• Continuously Variable High Pass: 40Hz to 400Hz
• Frequency Multiplier: x1 or x20
• Crossover Slope: 6dB/octave or 18dB/octave

By providing these customizable options, the EC20B allows you to tailor the audio output of your car audio system to your specific preferences and requirements, ensuring optimal performance and sound quality.
