Tube Tech SSA 2B Stereo Summing Amplifier

Tube Tech SSA 2B Stereo Summing Amplifier with a wide frequency response and low self and distortion noise

Tube Tech SSA 2B Stereo Summing Amplifier

TUBE-TECH SSA2B sums your mixes Wide, Punchy and Transparent, with Rock Solid Low End!

Sonically The SSA2B very easily outperforms the mix quality of any digital audio workstation and even betters the performance of mixing amplifiers built into the most high-end analog consoles.

For those of you that haven't yet experienced the difference between even the best ITB mix and the real thing: Do yourself a favor and listen to the SSA2B

Fact: The SSA2B sums your mix clearer, wider and punchier than anything, you've heard before. With a simple, but well organized setup based around the SSA2B it''s possible to raise your mixing to a level, previously only achievable from the best and most expensive consoles.

Low end: The TUBE-TECH SSA2B will deliver the tightest low end on the planet. Every user, we have been in contact with tells us about real low end improvement when using the SSA2B for summing.

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).

How does a zero field transformer work?

In the zero field transformer configuration, the transformer is part of the feedback circuit.There are several benefits for this:

  • 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.
  • The distortion at low frequencies is reduced substantially.
  • Frequency response in both the low and high range is extended.
  • Phase response in both the low and high range, is also reduced.
