SPL Crossover Active Analog 2-way Crossover (Silver)

The SPL Crossover is a one-of-a-kind active analog 2-way crossover - it is all analog - no DSPs, no AD/DA conversion. It is active and fits all kinds of speakers. You can tune crossover frequencies and phase response all in the analog domain in real time with real switches and controls, and, of course, with SPL's unique VOLTAiR technology. That means headroom, dynamic range and real sound in abundance.When you add a subwoofers to your top/main speakers the crossover is most often digital. That is been sold as a plus – but it isn't. Because digital signal processing involves AD-conversion, DSP processing and DA-conversion, the audio signal undergoes significant treatments not ideal for audiophile quality playback. But now, here is the solution: the SPL Crossover. Fully analog, 120 V VOLTAiR technology, user friendly and amazing sounding.The Crossover is split into two sections: the LOW section for the subwoofers (mono or stereo) and the MID-HI section for the top/main speakers. The crossover frequencies for LOW and MID-HI are identical and can be switched individually from 50 Hz to 120 Hz in 6 steps. The LOW-pass filter is 24 dB/octave steep. The MID-HIpass filter can be switched from 12 dB/octave to 24 dB/octave. Set to 24 dB/octave both filters operate in a Linkwitz/Riley design.The Crossover features a fully variable phase control to perfectly align the phase of the subwoofer(s) to the top/main speakers. The Phase control can be switched off and taken out of the signal path if not needed to maintain the shortest possible signal flow. If needed, the toggle switch engages the Phase control at 0° phase or at -180° phase. From these two starting points the phase can be varied from 0° to +180° resulting in a full 360° phase circle with the Phase control pot.
