SPL Crossover Active Analog 2 Way Crossover

SPL Crossover Active Analog 2 Way Crossover

Finally an analog crossover again

It is difficult to optimally integrate bass loudspeakers or subwoofers. At present, there are almost only digital crossovers for this purpose. But who wants to convert back and forth? You don’t need to anymore. SPL's Crossover sets the crossovers anew.

Crossing over

The crossover is divided into two section: The Low section for the bass loudspeaker or subwoofer (mono or stereo) and the Mid-Hi section for the top/main speakers.

The crossover frequencies for Low and Mid-Hi can be set individually from 50 Hz to 120 Hz in 6 positions.

The Low filter has a slope of 24 dB per octave. The slope of the MID-HI filter can be switched from 12 dB (Butterworth) to 24 dB (Linkwitz/Riley).

In Phase

Audio signals should come from the top speakers and bass loudspeakers or subwoofers in phase. The crossover offers variable phase control for this purpose.

Use the toggle switch to activate the phase control (phase 0° or phase -180°) and use the control to establish simultaneousness.

If the phase control is not required, it can be switched off and thus disappears completely from the signal path.

One or two?

If you want to connect two bass loudspeakers or subwoofers (one for L and one for R), this switch should be set to stereo.

If you only use one bass loudspeaker or subwoofer, switch to mono. The crossover creates a mono signal of the Low frequencies and outputs it to both Low outputs (L + R).

Sources

The Crossover offers both balanced inputs with XLR sockets and standard inputs with gold-plated RCA sockets.

Low & Mid-Hi

On the output side, the power amplifiers or active loudspeakers as well as bass loudspeakers or subwoofers are connected to the Low & Mid-Hi output sockets by means of balanced XLRs. This means that even long cable runs to e.g. mono power amps placed next to the speaker are possible without the risk of interference.

AMP CTL

Practical are the AMP CTL sockets, to which up to four power amplifiers with 12 V trigger inputs can be connected to switch them on and off together with the crossover.

The crossover itself can also be switched on by a preamplifier like the Director Mk2 or Phonitor x.
