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.
AC
Upgrades:
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.
Loudspeakers
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 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 electrical shock.
