Radial Twin-Servo Microphone Preamplifier

The Jensen Twin-Servo 500 is a faithful recreation of Deane Jensen’s famous 990 microphone preamp in a 500 series format. This unparalleled circuit design includes two cascaded 990 op-amps to share the load and provide 60dB of clean gain, as well as two servos that eliminate signal degrading capacitors from the audio path that allow for less than -120dBu of noise. Oversized Jensen input and output transformers produce an exceptionally wide frequency response and plenty of headroom. Twin-Servo is well-suited for recording highly dynamic sources, with 91dB of dynamic handling. Even more important than the specifications is the sound of the Twin-Servo; exceptionally natural and transparent, with detailed highs and an extended low end that will have you hearing your mics like never before.
