Radial Engineering Twin Servo - Microphone Preamplifier

500 Series Microphone Preamp The Twin-Servo is a high performance microphone preamp that leverages two discrete 990 op-amps for incredibly clean and transparent operation. Exceptionally wide frequency response from 0.5Hz to 150kHz Twin-Servo topology eliminates capacitors in the signal path Virtually zero phase shift or bandwidth limitation Oversized Jensen transformers for maximum headroom Legendary Performance The Twin-Servo utilizes the now-famous JE-990 circuit originally developed by industry icon Deane Jensen in 1988, providing an update in the 500 series format. Its superior performance is derived from two 100% discrete 990 op-amps cascaded in tandem to deliver 60dB of gain with less than 1/10th the distortion and twice the bandwidth of a single stage design. This also reduces noise at mid and low levels, a critical advantage for those that record with a wide dynamic range. In order to minimize phase distortion, all capacitors have been removed from the audio signal path and
