Tube Summing Mixer

Many grieve the sound of the era of analog mixer consoles but don’t want to waive the modern conveniences like total recall.

The Tube Summing Mixer gives you the opportunity to bring the sound of analog mixing with the benefits of a digital workflow to the comfort of your own studio.

The analog signal path, tubes and matching transformers, are responsible for processing the signals. The result is a typical analog sound; open & defined yet warm. The mix is not trapped in the box but opens up the whole room.

With 2 × 20 channels, there are enough inputs available to glue together the most demanding mixes. If 40 inputs aren’t enough for you, several Tube Summing Mixers can be cascaded to increase the input count. As you can use more than one Tube Summing Mixer together, nothing stands in the way of your surround mixes.

To ensure the exact reproducibility of a mix, the Tube Summing Mixer is equipped with a stepped output switch instead of a potentiometer. This allows a practical reduction at -3dB increments.

If you wish to insert mono signals into the mix, just insert the signal into the lower TRS jack. The mono signal is then automatically distributed to both channels simultaneously making it appear in the phantom center of the mix.

"The audio material loses corners and is significantly more compressed, especially in the midrange, than without analog summing.

Short, percussive sounds are only slightly decanted and experience a comparatively small change in sound. On the other hand, pads or already heavily compressed material experiences a significant increase in pressure, it becomes softer and more balanced in frequency.

It is also worth mentioning that the sound coloration does not affect the treble or bass range. Failures, such as a treble cut or lack of punch below 100 Hz, are therefore not to be feared."

"The individual signals appear contoured and lively and the sound image tastefully gains color and expressiveness.

The spatial information becomes more apparent, which results in a deeper listening impression. The sound image appears more vivid and acquires more three-dimensionality."
  • 2006-11
  • Andreas Hau
"The result already sounds much more like the sound image you are used to from analog productions than the purely digitally played out mix.

Your mix sounds as tight and crisp as before, just a bit 'deburred' and gently rounded at the corners"
