Brand new for 2024, The Manley OASIS Phono Stage replaces the CHINOOK
At last, our favorite phono stage has been updated to operate with MANLEY POWER® which provides an even quieter blacker black background, yielding quicker sonic extremes over our older linear PSU designs. President EveAnna Manley recalls the moment she first made the comparison, “I brought a regular CHINOOK with its linear power supply, a stock unit, to Los Angeles to listen to it against a second CHINOOK that had been modified to work with our new MANLEY POWER® switch mode power supply. My buddy Pete Lyman at Infrasonic Mastering spun up some vinyl records that he had cut the masters for on his lathe. Using his mastering studio environment, we were able to conduct a very precise comparative listening test between the two units. And even though we could not see which unit we were listening to, the sonic differences were unmistakable, and we both heard the same superiority in the new power supply design. I still can’t believe what a stunning technical and sonic accomplishment MANLEY POWER represents, and delivers as we adopt more of our designs to take advantage of our proprietary system.”
The OASIS Phono Stage offers an improvement in convenience over the older CHINOOK as the GAIN selections have been brought out from inside the chassis to the rear panel for easier access residing next to the resistive and capacitive loading DIP switches. There are tons of loading options to mate with any Moving Coil or Moving Magnet cartridge. Once you have set your GAIN and Loading for your cartridge, you’re done! Set it and forget it!
The OASIS sports an upgraded more luxurious chassis design while its efficient internal build keeps the price affordable. And like all Manley products, each OASIS Phono Stage is loyally handcrafted in the USA by American men and women at our Southern Californian factory located just 35 miles east of Los Angeles.
- Vacuum Tube Complement 6922 x 2 (gain stage) plus 6922 x2 (output stage). Any 6DJ8, 7308, ECC88 types may be used.
- Unbalanced Input and Output connections via Manley Teflon ® & Gold plated RCA jacks
- Automatic Mute Timer On initial power up output jacks are muted for approximately 45 seconds. Automatic mute circuit allows tubes to warm up and circuitry to settle. At power down, output jacks are immediately muted.
- Input Termination Capacitance 3-position user-selectable capacitor values of 50pF, 100pF, and 200pF yield resultant combinations of: 50, 100, 150, 200, 250, 300, and 350pF. Use these settings typically for Moving Magnet (MM) cartridges.
- Default Input Impedance 47k Ohms, with no other DIP switches selected. Use this setting typically for Moving Magnet (MM) cartridges.
- Selectable Input Impedance 5-position user-selectable resistor values of 50, 100, 200, 400, and 800 Ohms. There are 32 possible loading possibilities. Use these resistive loading choices typically for Moving Coil (MC) cartridges.
- Gain Rear Panel DIP switches select 45dB, 50dB, 60dB, or 65dB
- Deviation from RIAA curve Less than ± 0.5 dB from 20Hz to 20kHz at any gain setting. Typically less than ±1dB from 10Hz to 100kHz.
- Distortion (THD+N) (47k Ohm Input Termination, 45dB gain, 1kHz sine, 0dBu output): Typical 0.010% THD+N, into 100k Ohm load, BW = 100Hz-22kHz (47k Ohm Input Termination, 45dB gain, 1kHz sine, 0dBu output): Typical 0.030% THD+N, into 600 Ohm load, BW = 100Hz-22kHz
- Dynamic Range (Gain set to 45db, 200 Ohm source): 91dB @ 1kHz, 0.1% THD+N, BW = 22Hz-22kHz (Gain set to 45db, 200 Ohm source): 107dB @ 1kHz, 1.0% THD+N, BW = 22Hz-22kHz
- Noise Floor at 45dB gain setting with shorted input: -84 dBu, A-weighted at 60dB gain setting with shorted input: -75 dBu, A-weighted
- Maximum Input at 45dB gain setting with 20 Ohm Source Z @ 1kHz into 10 kOhm load: 250mV RMS = +34.5 dBu @ 1% THD+N BW=22Hz-22kHz at 60dB gain setting with 20 Ohm Source Z @ 1kHz into 10 kOhm load: 40mV RMS = +34.2 dBu @ 1% THD+N BW=22Hz-22kHz
- Maximum Output +37dBu @ 1kHz, 1.5% THD+N into 100 kOhm load
- Output Impedance 91 Ohms
