Best Planet Audio Signal Amplifiers

View larger 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 center frequency ranges: Front (high pass) - 40-400Hz or 800Hz-8kHz; Rear (high pass) - 40-400Hz; Subwoofer (low pass) - 32-250Hz Crossover slope, front and rear: selectable 6d8/octave or 18d8/octave Crossover slope, sub channel: 18dB/octave Bass Boost center frequency range: 25-250Hz Bass Boost level adjustment: 0-+12dB Signal-to-Noise Ratio: 110dB THD: 0. 01% Channel separation: 80dB Input impedance: 20kOhms Output impedance: 100 Ohms Output gain: 1:2 (+6dB) Power supply: PWM type Output voltage: 8V maximum1 Dimensions (W x D x H): 5-1/8" x 8-1/4" x 1-3/4" 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 ... [Read More]
