Product Description
The Jensen Twin Servo 990 mic preamp is considered the worlds finest mic preamp by audio experts. It's the ideal integration of advanced design software, hardware, engineering know-how, and carefully controlled 'golden ears' tests. It has earned high marks for sonic performance since its introduction in 1988.
The basic circuit was originally published as an application note by Jensen for their finest microphone input transformer, the JT-16-B. Each channel uses two precision 990C operational amplifiers modules, developed and patented by Jensen, to achieve one tenth the distortion and twice the bandwidth of a single stage design.
The Jensen Twin Servo 990 has a 19" wide mainframe rack-mount chassis (1.75"H x 19"W x 8"D) and can be ordered with 1 to 4 channels. Additional channels can be easily added later up to the total capacity of the mainframe.
Highlights:
- JT-16-B - input transformer
- Two 990 discrete op-amps per channel - faster, quieter, more powerful and better sounding than typical monolithic op-amp
- Elimination of all coupling capacitors from the signal path - results in less degradation of the audio signal
- JT-11-BMQ - output transformer
- Input bias current compensation circuitry and DC servo circuitry - eliminates signal degrading coupling capacitors
