Each passive crossover significantly worsened the phase-accurate playback with your passive components (capacitors and inductors). In the vehicle, the distance between each speaker (actually always) different and therefore the signals also come with different phase angles to her ear. Passive switches offer no possibility of individual adjustment! In the active approach the frequency distribution on the signal amplification is carried out and allows only gets supplied to each speaker, the optimized signal for him. Each connected speaker is powered by its own amplifier and together with the various control options makes the continuously variable phase control, the optimum sound adjustment in difficult installation situations possible! Thus sound dreams come true! The SL A-260.4 amplifier integrated active and flexible signal schemes for stereo systems. The volume is separated for all Bass and Mid / tweeter. Adjustable crossover frequencies 2-4 kHz, transition time adjustable 12 or 18 dB. Adjustable subsonic filter of 25 - 150 Hz / 24 dB, phase balance control variable 0 - 180 ?, and as a special feature continuously variable phase control between the tweeter and the woofer 0 - 180 ?. 2x 150 Watt RMS Tief-/Mittelton + 2x 50 watts RMS Tweeter Input Sensitivity 200mV - 6V Signal to Noise Ratio> 90dB Tief-/Mittelton 20-4500 Hz / high range 1.5 - 30 kHz THD / THD 0.04% to Dimensions in mm: length 460 x width 195 x height 62 mm
