Manley Chinook

The spawn of the Manley Steelhead - one of the world's greatest phono preamplifiers - Stereophile Class A Recommended Component and The Absolute Sound's Preamp of the Year, has arrived. The Chinook epitomizes the sound of the Steelhead. Designed for the music lover, not the switch tweaker.

Setting up the Chinook couldn't be easier. There are two internal settings for optimal gain: 45dB for Moving-Magnet cartridges and 60dB for Moving-Coil cartridges. Set it and forget it! The back panel contains DIP switches for adjusting the input resistive and capacitance loading values. 31 possible options between 26 and 800 Ohms plus 47k Ohms and 7 capacitive loading choices between 50 pF and 350 pF provide flexibility to match any cartridge and fine tune the tone.

Specifications:

• Gain: Internal DIP switches select 45dB or 60dB

• 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

• Distortion (THD+N) (47k Ohm Input Termination, 45dB gain, 1kHz sine, 0dBu output): Typical 0.030% THD+N, into 600 Ohm load, BW = 100Hz-22kHz
