SPL Crossover Active Analog 2-Way Crossover

The SPL Crossover is one of a kind!

• It's analog: No DSPs, no AD/DA conversion.
• It's active: It fits to 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 subwoofer 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 and at least the extra AD/DA conversion does not amuse audiophiles. 

But now, here is the solution: the SPL Crossover. Fully analog, 120V-VOLTAiR technology, user friendly and amazing sounding.

Features:

• X-Over Frequencies: 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. 
• Phase Control: The Crossover features a fully variable phase control to perfectly align the phase of the subwoofer(s) to the top/main speakers. 
• Mono/Stereo: The LOW section features a Mono/Stereo toggle switch. 
• Crossover On/Off: The MID-HI filter can be switched on and off. This is useful in case the top/main speakers shall operate full range and only the LOW filter shall roll off the subwoofer at a defined frequency.
• Low Cut: An additional Low Cut filter is provided to cut all frequencies below 20Hz. This is especially useful to relieve the power amplifiers from amplifying inaudible very low frequent signals that only cause the chassis to moves excessively.
• Low Level: The output level of the subwoofer can be varied from -10dB to +10dB. After setting the crossover frequency and aligning the phase the level is the third control parameter. 
• VU Meters: The two VU meters show the volume units. It's mechanical design "slows" the measurement, averaging out peaks and troughs of short duration, and reflects thereby more the perceived loudness or 'energy'. 
• AMP CTL (Amplifier Control): When powering on the Crossover up to four other power amplifiers can be wire-linked for simultaneous power on/off. And if your pre-amplifier is a Director or Phonitor x you can power up the Crossover and up to four power amplifiers together.
