This is the last of the original Bybee Technologies Purifiers to leave the factory. In addition to the normal three levels of Quantum Filters on EACH circuit the ground lines are also Quantum Filtered. The stock Pro Model only has the hot and neutral lines filtered. The very latest Bybee Conditioners also have added filtration on the ground circuit, allbiet at a $5 to $6k price level.
The two circuits have been internally bridged together giving SIX levels of filtration to the downstream circuit with three levels of filters in between the circuits. The following page from the User Manual describes the advantages of a bridged Purifier. By internally connecting the 2 circuits the use of all 4 outlets in each circuit is maintained.
Installation without Dedicated AC Circuits
Some systems will not have dedicated lines available. For these systems it is possible to effectively utilize the separate circuits in a series configuration which will effectively double the number of Quantum Mechanical Filter modules being employed in the four digital outlets.
The drawing below illustrates the proper methods for connecting the circuits to employ both Quantum Mechanical Filter modules in series.
Plug the wall cord into the ANALOG IEC input socket. Utilize the second power cord furnished with the Purifier as a jumper by plugging the cord into an analog outlet socket and inserting the IEC end into the IEC input socket of the digital section. The “digital section” of the Signature Model will have the effect of double filtration while the Pro Model will have six levels of filtration. The remaining three “Analog” outlets are still available and are both filtered and isolated from the “Digital” section by either one or three Quantum Mechanical Filter elements. So while not optimally isolated by isolated circuits the two circuits are nevertheless substantially separated from cross contamination.
The two circuits should be viewed as “CIRCUIT 1” and “CIRCUIT 2”. CIRCUIT 1 is single or triple filtered while CIRCUIT 2 is either double or six times filtered. Normally the preamp and phono stage will benefit the most from the double filtering of CIRCUIT 2 with the turntable, digital transport and DAC connected to the CIRCUIT 1. Experimentation with your components should be done to determine the optimum configuration. While we are used to thinking of circuit separation in terms of digital vs analog it is not so simple. The worst emitters of grunge and hash back into the AC line are components with an electrical motor; Digital transports, turntable motors, tape decks, VCRs etc. These components should be isolated on their own circuit, or by connecting all to CIRCUIT 1 of a bridged Purifier. Even further isolation can be obtained by the use of a Bybee Quantum Charger at the end of the AC cord. The Quantum Charger will not only filter the AC power into the component it will filter out much of the contamination being generated by that device.
The Purifier is almost like new with only 2 scratches I can see.
It also includes a Harmonic Technology Pro AC 11 Power Cord, user manual and original shipping boxes. The Pro-AC11 is constructed with the finest high purity copper. Two shields UL/CL-3 are used for superior RFI rejection.
