FRYBABY2 Compact Burn-in Generator

Description
The FryBaby2 audio system conditioner is a burn-in signal generator designed
especially for cables and interconnects. 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.

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!

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.
