Ultra-low noise, low distortion and wide frequency range. Tube Tech know what you want from your summing amplifier.

  • Balanced XLR I/O: 10 stereo inputs, 1 stereo output
  • 2 first stereo inputs can be used as 4 mono inputs
  • Master output gain: -10dB to +10dB
  • Maximum input: > +30dBu
  • Low noise: < -85 dBu @ all inputs terminated
  • Frequency response: 5Hz - 100kHz
  • Distortion: <0.05%
  • 23-step gold plated output gain control
  • Dual VU meters show output level
  • 19" rackmountable

The SSA2B features Tube Tech's signature transformer balanced inputs and outputs along with symmetrical circuitry throughout.

Due to the quality of components, the SSA2B is capable of processing extremely high levels, and the entirety of inputs is balanced by two zero field transformers (left and right)

One word of warning to engineers - due to the way the SSA2B is wired, mono inputs left open will narrow the stereo image considerable. To avoid this simply switch mono inputs to stereo, connect to outputs (even if not used) or terminate using shorting plugs.
