SSA2B Stereo Summing Amplifier
SSA2B Stereo Summing Amplifier SSA2B Stereo Summing Amplifier


The TUBE-TECH SSA 2B Stereo Summing Amplifier features two very low noise/low distortion summing amplifiers with a very wide frequency response. It provides a high-end, yet cost-effective solution for analog summing, and the simple layout of the SSA 2B makes recall just as easy as when you work ITB.

The SSA 2B sums your mix cleaner, wider and punchier than anything, you've heard before. It makes it possible to perform your mixing at a level previously only achievable from summing with the best and most expensive consoles, and the low-end response just doesn't get any better than this, SSA2B features 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! 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


  • Summing amplifier at the input, a 23 stepped attenuator with a range of +/- 10 dB and an output stage
  • Symmetrical two-stage amplifier, designed around two dual, low impedance, and high transconductance triodes
  • Input transformer is a part of the dual feedback configured as a so-called zero field transformer
  • Output stage is designed around two dual triodes in push-pull and an output transformer (with a static screen)
