It can also be used to burn-in linestages, phonostages, and amplifiers. The sophisticated electronic waveform – a combination of wideband noise and variable frequency amplitude modulation – is designed to exercise both low and high frequency characteristics of conductors and insulators. Specifications Item Output Voltage Current Limit Signal Bandwidth AC Voltage Specification 1Vrms (LINE), 10mVrms (MM), 1mVrms (MC) 10mA 10Hz to 1MHz 120V/240V FRYBABY2 Compact Burn-in Generator 4 Operation The FryBaby2’s control knob sets the mode of operation. MC selects an output level suitable for driving moving coil phonostage inputs (-60dB), MM for moving magnet phonostages (-40dB), and ON for everything else (line level). The internal LED blinks at the rate of modulation. There are two modes of cable burn-in, voltage and current. Both are required for maximum effectiveness. Voltage Mode In voltage mode the cable dielectric is excited by electric fields. Leave the far end of the cable open-circuited (see diagrams in following section). Current Mode In current mode, the cable is short circuited, and conductors are exercised via magnetic fields. Short-circuit the far end of the cable or form a loop by returning the cable to the other FryBaby2 output. Current mode is not applicable when using the FryBaby2 to burn in amplification. Duration It is best to do a voltage burn for 24 hours followed by a current burn for 48 hours. Note: silver conductors typically take twice as long! FRYBABY2 Compact Burn-in Generator 5 Connections The FryBaby2 is designed to burn-in and condition cables offline. It can also be used as a signal generator to break-in amplifiers or other electronics. RCA The FryBaby2 can burn in a stereo pair of interconnects by using the female-tofemale adapter at the far end. First, do a voltage burn by connecting the interconnect pair directly to the FryBaby2 outputs. Set to ON. After the voltage burn, do a current burn by inserting the adapter to close the loop. Phonostage, Linestage, Amplifier Amplification electronics are burned in using voltage mode. Connect the FryBaby2 outputs to the inputs on your phonostage (you’ll need an interconnect). Set the output amplitude to either MC or MM, depending on the gain of your phonostage. This sets the burn-in signal to the correct amplitude and equalization. For linestages or other types of amplifiers, use the ON level output. Amplifier must be powered on. Troubleshooting If the LED is not lit, check the power supply and rotary switch.
