Tube-Tech SSA 2B

Tube-Tech SSA 2B sums your mix clearer, wider and punchier than anything, you’ve heard before.

The SSA 2B is the sound solution to the bottleneck problems arising when down-mixing digital recordings on DAW’s.
The TUBE-TECH 20->2 channel down-mixing unit directly targets the critical mix down process:

Sonically it very easily outperforms the quality of digital audio workstations and even betters the performance of mixing amplifiers built into the most high-end analogue consoles.

As we say: Step out of the Digital Mist, out into Clear Analogue Air

Product Description

The TUBE-TECH SSA 2B Stereo Summing Amplifier features two very low noise / low distortion summing amplifiers with a very wide frequency response. The inputs are transformer balanced and the circuits are symmetrical from input to output. The inputs are capable of handling extremely high input levels. The Outputs are balanced and have fully floating transformers with a static screen. The power supply and the sidechain circuits are based on a solid-state circuit. With the exception of the output stage all DC voltages are stabilised.

SSA2B Summing principle:

All inputs are balanced by two zero field transformers (one for each channel).
What is zero field transformer?

In the zero field transformer configurations, the transformer is part of the feedback circuit.

There are several benefits for this:

1. The voltage across the transformer is reduced substantially whereby a much smaller transformer is needed for the same specification.
The reduction is of the same magnitude as the feedback applied.
2. The distortion at low frequencies is reduced substantially.
2. Frequency response in both the low and high range is extended.
3. Phase response in both the low and high range, is also reduced
