Studio Channel

Tube Tech's SSA 2B is a stereo summation amplifier with eight stereo inputs, four mono inputs, one stereo output and VU meters. The Tube-Tech SSA 2B stereo adder has two low noise and distortion summation amplifiers with a very wide frequency response. The inputs of the SSA 2B are symmetrical with respect to the transformer, and the circuits are symmetrical from the input to the output. Inputs are able to handle extremely high levels. The outputs are symmetrical and have fully floating transformers with static screen. The power supply and sidechain circuits are based on a semiconductor circuit. Tube-Tech's SSA 2B offers an astonishing analog summation for a digital world.
