The Tube-Tech SSA2A Summing Amplifier. High-end, solution to the bottleneck problems arising when down-mixing digital recordings on DAW’s.

The Tube-Tech SSA2A 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. The SSA 2A is the sound solution to the bottleneck problems arising when down-mixing digital recordings on DAW’s. Tube-Techs 4+16 - to 2 channel down-mixing unit directly targets the critical mastering process: Sonically it easily outperforms the quality of digital audio workstations and even betters the performance of mixing amplifiers built into the most high-end analogue consoles.

The main features of the Tube-Tech SSA2A include:

• High-end, solution to the bottleneck problems arising when down-mixing digital recordings on DAW’s
