Features and Specifications
MANLEY CHINOOK PHONO STAGE
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 (MM/MC): 3-position user-selectable capacitor values of 50pF, 100pF, and 200pF yield resultant combinations of: 50, 100, 150, 200, 250, 300, and 350pF
Moving Magnet Input Impedance: 47k Ohms, fixed
Moving Coil (MC) Input Impedance: 5-position user-selectable resistor values of 50, 100, 200, 400, and 800 Ohms. There are 32 possible loading possibilities. See chart:
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
