Manley OASIS Phono Stage: A New Era of Precision and Flexibility

The Manley OASIS Phono Stage represents a leap forward in vinyl playback, blending advanced features with audiophile-grade craftsmanship. Powered by the proprietary MANLEY POWER® system, the OASIS delivers a quieter and more dynamic soundstage compared to its predecessor, the Chinook. With its updated design, external gain controls, and extensive loading options, the OASIS is the ultimate tool for vinyl enthusiasts seeking sonic excellence and cartridge flexibility.

From its precision RIAA equalization to its low-noise tube design, the OASIS exemplifies the best in phono preamplifier technology. Its intuitive setup, handcrafted build, and elegant chassis make it a centerpiece in any high-fidelity audio system.

Key Features

1. Advanced Cartridge Matching
   • Gain Settings: 45dB, 50dB, 60dB, and 65dB selectable via rear-panel DIP switches.
   • Input Impedance Options: 32 possible resistive loads from 26 to 800 Ohms plus 47k Ohms for MC and MM cartridges.
   • Capacitive Loading Options: 50pF to 350pF in user-selectable combinations for MM cartridges.
2. Quiet and Accurate Performance
   • Powered by MANLEY POWER® for ultra-low noise and a “blacker” background.
   • Passive RIAA equalization ensures accurate frequency response within ±0.5 dB from 20Hz to 20kHz.
3. High-Quality Tube Circuitry
   • Tube Complement:
     • 2 x 6922 for gain stages.
     • 2 x 6922 for output stages in a White Follower configuration for ultra-low output impedance (91 Ohms).
   • All-tube design, free of integrated circuits in the signal path, for a pure and dynamic sound.
4. User-Friendly Setup
   • Rear-panel controls for gain, resistive loading, and capacitive loading make it easy to fine-tune cartridge settings.
   • Automatic mute function during power-up and power-down prevents unwanted noise.
5. Elegant and Robust Design
   • New zinc-passivated steel chassis with powder-coated finish for durability and aesthetics.
   • CNC-milled faceplate with “racetrack” insert available in Pewter Grey or Black.
6. Handcrafted in the USA
   • Built by skilled artisans in Southern California, ensuring reliability and attention to detail.
