Description
The Radial Jensen Twin-Servo 500 Series Microphone Preamplifier Module is a powerhouse of precision and clarity, designed to elevate your studio recordings. An update of the classic design from 1988, this preamp delivers 60dB of gain with unparalleled transparency and minimal distortion. At its core, the Twin-Servo boasts two discrete 990 op-amps, eradicating capacitors from the signal path to ensure a pristine audio experience. This configuration not only enhances the dynamic range but also reduces phase distortion, preserving the integrity of your sound.
Equipped with oversized Jensen transformers, the Twin-Servo offers an impressive frequency response from 0.2Hz to 150kHz, ensuring your recordings capture every nuance. Its robust design includes a 10-segment LED meter for precise signal monitoring, allowing you to adjust levels with confidence. The front-panel combination input, featuring Neutrik connectors, provides seamless connectivity with both XLR and 1/4-inch inputs.
The Twin-Servo is packed with thoughtful features for the discerning audio engineer: a 180º polarity reverse switch to maintain phase integrity, a high-pass filter to manage resonance, a -15dB pad to prevent overload, and +48V phantom power for condenser mics. Whether you're capturing delicate vocals or thundering instruments, this preamp module offers the versatility and reliability you need to produce stellar recordings.
