Crossover

Finally an analog crossover again

It is difficult to optimally integrate 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. Our Crossover sets the crossovers anew.

Crossing over

The crossover is divided into two section: The Low section for the 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 speakers and 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 subwoofers (one for L and one for R), this switch should be set to stereo.

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

"In practice, it is easy to integrate a subwoofer into an existing loudspeaker concept with the "Crossover". Flexible, easy to adjust and with a sound that is undetectable when configured correctly: Respect, SPL!"

Wolfgang Vogel

On or off?

If you prefer to run the top/main speakers full-range, you can switch off the MID-Hi filter.

Get rid off it

With the Low Cut filter all frequencies below 20 Hz can be filtered out with a 6dB roll-off. This way, no inaudible low frequencies get into the power amplifier, which relieves it a lot.

As long as you're having fun

The output volume of the subwoofer can be varied from -10 dB to +10 dB.

In addition to the purely corrective adjustment of the speaker system, you can add more bass into recordings that lack low end. 

It’s like saying, “Happiness is when the bass kicks in.”

Good ol' times

Two mechanical VU meters visualize the input levels for the left and right audio channel.

With the VU switch you can optimize the display for different signal levels.

Sources

The Elector 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 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.

The VOLTAiR Technology

What exactly is that?

And what does it do?

Good questions need good answers. And that’s what the 120V video gives you.

VOLTAiR is that good

In the lab, we pitted Phonitor xe against the best audio measurement system and found that Audio Precision could not measure VOLTAiR technology.
