PRV Audio's EX4.6 PRO electronic crossover gives you tons of flexibility to make it easy to tune your car audio system for optimum sound. With 4-way adjustable high and low pass filters and also output level control on each channel this crossover gives you a wide variety of adjustments for most situations. To get maximum power and impact from your system the EX4.6 PRO also includes an 0-12 dB bass boost at 45 Hz on the subwoofer output _x000D_ _x000D_ The EX4.6 PRO uses a unique 2 or 4 channel input (1 stereo and 2 mono inputs) with 6 channel output setup (2 stereo and 2 mono outputs) to give you many options when designing your system. If using just the 2 channel stereo input you have the ability to rout the signals to all 6 outputs to run stereo midranges and tweeters with mono subwoofer and midbass. This feature ensures that all the capability of this crossover can be utilized even with the simplest of sources. _x000D_ _x000D_ With up to 9 volts RMS of output on each channel, the EX4.6 PRO will help to keep your system quiet and even give you plenty of power to split the outputs for running multiple amplifiers. Induced noise in an audio system is generally very low voltage, so the high output voltage capability creates a greater differential between noise and the actual audio signal. This this means that you can set your amplifier gains lower to amplify less unwanted noise with no loss in overall output capability. Also, when running multiple subwoofer amplifiers this extreme output capability means that you can split the signal and still have enough headroom to push each amplifier to their limit. _x000D_ _x000D_ Specifications: _x000D_ • High out channels: High pass - adjustable 400 to 10,000 Hz (12 dB/octave) _x000D_ • Mid high out channels: High pass - adjustable 150 to 5,000 Hz (12 dB/octave) _x000D_ Low pass - adjustable 700 to 15,000 Hz (12 dB/octave) _x000D_ • Mid low out channel: High pass - adjustable 25 to 4,000 Hz (12 dB/octave) _x000D_ Low pass - adjustable 300 to 5,000 Hz (12 dB/octave) _x000D_ • Sub out channel: Low pass - adjustable 55 to 300 Hz (12 dB/octave) _x000D_ Bass boost - adjustable 0 to +12 dB@ 45 Hz _x000D_ • Max output voltage: 9V RMS _x000D_ • Max input voltave: 4V RMS _x000D_ • Signal to Noise: >90 dB _x000D_ • Input impedance: 10K ohms _x000D_ • Distortion: 0.02% THD _x000D_ • Channel seperation: >80 dB _x000D_ • Frequency response: 20 to 20,000 Hz _x000D_ • Supply voltage: 10V - 16V DC _x000D_ • Current consumption: 200 mA _x000D_ • Output impedance: 470 ohms _x000D_ • Dimensions: 1.3" H x 9" W x 6.3" D _x000D_ • Weight: 1.45 lbs.
