The TUBE-TECH SSA 2A 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.
8 stereo+4 mono inputs - 1 stereo output
23-step gold plated output gain control
Master Output Gain: -10 dB to +10 dB
Fully symmetrical circuitry from input to output
Zero field transformer balanced inputs.
