Tegeler Audio Tube Summing Mixer

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.
