Equipment Modification Guidelines For Bybee Quantum Purifiers
Bybee Quantum Purifiers have proven effective in numerous locations for every
type of audio/video component and loudspeaker. Among the most common are
AC power, audio/video inputs and outputs, and digital inputs and outputs.
A good general principle for all installations is to place the Bybee Quantum
Purifier as near as possible to the destination end of the AC or signal path.
It is recommended to use the large purifiers for AC and loudspeaker
modifications if physical space permits. Where space is limited, for instance with
some source components, the small purifiers may be substituted as long as the
current flow through them and does not exceed 4.3 A. It is typically more
convenient to use small purifiers in modifying analog and digital circuits, although
large purifiers may be used In those applications if space permits.
The simplest AC modification is to primary power: Place the purifiers between
the AC input -- typically an IEC socket -- and the transformer input. For best
results the recommended procedure is to put a purifier on both the hot and the
neutral leg; besides yielding better sound, this will ensure full quantum
purification even if the component is connected to an incorrectly wired (out of
polarity) AC receptacle. If it is certain that the wall outlet is wired with correct
polarity, the purifier on the neutral leg may be omitted, with some decrease in
sonic performance. Note: If the equipment is used in a location that has
balanced AC power, both the hot and neutral legs must be modified, and a third
purifier on the ground leg will result in optimal improvement.
The amount of voltage passing through a purifier is inconsequential. More
important is the amount of current. The large purifiers are rated for 15 A, the
small for 4.3 A. (These ratings reflect the capacity of the copper leads.)
An even more effective AC treatment is to secondary power: Place purifiers
between the transformer and the rectification diodes. The number of purifiers
required may vary according to the circuit design of the component. One purifier
should be used for each transformer tap utilized. Some users have reported
even more impressive results from placing purifiers after the diode bridge.
Note: Treating secondary power is NOT recommended for designs utilizing tube
rectification. In such cases it is preferable to modify the primary AC input. Also,
when trading secondary power in tube amplifiers, DO NOT place a purifier on the
filaments transformer tap.
Audio, video and digital inputs and outputs:
For optimum performance improvement with RCA jacks, connect a purifier at (or
as close as physically possible to) the positive terminal of the jack, and a second
purifier on the return leg. Treating only the positive leg will also enhance
performance, but to a lesser degree.
For XLR balanced input jacks, both hot and neutral must be treated. For XLR
output jacks, best results will come from additionally treating the ground --
although here too, the purifier for the ground may be omitted, with some
lessening of the performance improvement.
The best results come from treating inputs and outputs. However, if that
approach is too expensive, excellent results can still be achieved. As a rule,
placing the purifiers at inputs is slightly more effective than putting them on
outputs. Note: When upgrading a preamplifier, the input modification should be
placed after the selector switch, so that the input signals from all source
components get the benefit. In addition to the standard modifications described
above, there are other locations that can be modified to further improve
performance. Bybee Technologies can provide consultation on these other
performance-enhancing modifications if a schematic for the circuit is available.
To modify dynamic loudspeakers, the best possible results are obtained by
connecting a purifier at both the positive and negative terminals of each driver. A
less costly -- and less effective, although still worthwhile -- modification is to
place a large purifier at the positive and negative inputs to the crossover network,
so that all drivers get the benefit. If access to the crossover is difficult, the large
purifiers may be placed between the end of the speaker cable and the positive
and negative input terminals. (Be careful to avoid a short between the positive
and negative input terminals.
Note: For all of the above examples, very good improvements can be realized
even if the purifiers for the negative side are omitted. A good compromise is to
put purifiers at each transducers positive terminal and use a single purifier at the
negative crossover input or speaker terminal.
For modifying electrostatic loudspeakers, primary power can be treated as
described above. In addition, placing a purifier on the positive and negative stator
wires is even more effective.
AC wall outlets with a maximum current draw of 15 A or less may be modified
by placing a large purifier on both the positive and neutral connections. This
should be done only by a qualified electrician, as there is danger of injury from
