    The external power supply is in the Wyetech Labs tradition of using only passive devices and L- C type filtering. It consist of four separate supplies with three stages of filtering that ensures that only clean DC power is fed to the amplifier module.

    The Module is ideal for the most demanding applications requiring accurate RIAA equalization, very low noise, extremely low distortion and superior sonic performance. The Ruby P-1 module has been custom-built for Wyetech Labs by completely automated state of the art assembly methods using extremely precision components with tolerances to 0.1% accuracy.

    • High output drive. Balanced - 28V. Unbalanced - 14V • High accuracy RIAA equalization with 0.05dB tolerance • Selectable time constants of 3.18uS and/or 7950uS • Total harmonic distortion 0.0003% • Low output impedance [ 0.1 Ohm ] - drives long signal cables •...

  • Page 6: Factory Settings

    Factory settings The factory default settings for the phono module are: • 1000 Ohm loading resistance • 100 pf capacitance • 1mv (60 dB gain) sensitivity with rumble filter on (20Hz warp & infrasonic) These default settings should be appropriate for most moving magnet cartridges. Calibrating to match your cartridge To exactly match the phono stage module’s settings to the specifications of your cartridge (for example, for a moving coil cartridge), you will need to calibrate the module.

    Input Impedance Settings Resistive input loading, Ri The resistive input loading for MC/MM cartridges can be set in accordance with the cartridge manufacturer's recommendation or experimentally. Both channels must be set identically. Resistance, Ri Input impedance - DIP switch settings on/off Ohms Factory default setting Ruby P-1 phono stage preamplifier –...

    Capacitive input loading, Ci The capacitive input loading for MC/MM cartridges can be set in accordance with the cartridge manufacturer's recommendation or experimentally. Both channels must be set identically. Capacitance, Ci "Input impedance"-DIP switch settings on/off. Factory default setting Example: If your cartridge requires a load resistance of 40 Ohms and a load capacitance of 200 pF, the Ri/Ci DIP switch settings (1-8) should be off, on, off, on, off, on, on, off.

  • Page 10: Time And Gain Constants

    Time and gain constants Gain The gain required for MC/MM cartridges can be set in accordance with the manufacturer's specification for MC/MM nominal output level or experimentally. (For MC/MM nominal output levels below 0.10 mV (=100 μV), gain is set at 0.10 mV. For MC/MM nominal output levels above 10mV, gain is set at 10 mV). Both channels must be set identically unless balance adjustment is necessary.

  • Page 11: Time Constants (3.18 Μs And 7950 Μs)

    MC/MM nominal Gain DIP switch settings on/off output level 50.5 Time constants (3.18 μs and 7950 μs) It can be most advantageous to activate the time constant 7950 μs (20Hz) as a high pass filter (RIAA/IEC) to minimize warp and infrasonic signal interference. The time constant 3.18 μs (50kHz) is only activated if the phonograph disc is cut with this time constant.
