SPECIFICATIONS
•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, & 350pF
•Moving Magnet Input Impedance: 47k Ohms, fixed
•Moving Coil (MC) Input Impedance: 5-position user-selectable values of 50, 100, 200,400, 800 Ohms.
which yield 32 possible loading possibilities. See chart Fig. 3
•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):
THD+N, into 100k Ohm load, BW = 100Hz-22kHz Typical 0.010%
THD+N, into 600 Ohm load, BW = 100Hz-22kHz Typical 0.030%
•Dynamic Range: 91dB @ 1kHz, 0.1% THD+N, BW = 22Hz-22kHz
107dB @ 1kHz, 1.0% THD+N, BW = 22Hz-22kHz
•Noise Floor at 45dB gain setting: -84dBu, A-weighted
•Noise Floor at 60dB gain setting: -75 dBu, A-weighted
•Output Impedance: 50 Ohms
•Internal Power Supply: Fully regulated linear B+, Heater, and control voltage rails.
•Operating Mains Voltage: Units are built for original destination country's mains voltage:
100V, 120V, or 220-240VAC as indicated on the serial number badge.
•Power Consumption: 42 watts (345mA @ 120VAC)
•Mains Voltage Frequency: 50 ~ 60Hz
•Power Transformer: Toroid construction for low radiation.
•Badge Lamp: LED illumination
•Dimensions: W=19", L=11", H=3 1/2"
•Shipping Weight: 15 Lbs.
