Descripción
This unit incorporates a proven high power DC voltage offset removal circuit packaged in a RFI
and EMI blocking, magnetically shielded case.
To provide more flexibility and greatly increased integrity when connecting more than one
component, the PBDC SYMMETRY has 4 output sockets, each connected in star format to a
single uniform point, with the earth connections also star connected the single star point. The
earth/ground star point can also be accessed via the 4mm terminal socket on the case.
Star connection avoids the “Daisy Chaining” of power to the sockets as occurs with ordinary
power strips and with outlets arranged along a wall and brings considerable sonic benefits.
With the PBDC SYMMETRY for example; two mono block amplifiers, a preamp and a source
component can be connected to the mains in star format with all the advantages this brings in
addition to the considerable benefit gained from DC removal:
Removing DC enable transformers to function at greatest efficiency and lowest noise.
Component parts of your HiFi system take High Voltage Alternating Current from your wall
sockets and transform it to a lower voltage which is then converted to Direct Current to operate
the item. A transformer can be viewed as an electromagnetic pump. With AC power, volts rise
to a high positive voltage, fall through zero rising to an equivalent negative voltage and falling
back to zero repeating 50 or 60 times every second. A transformer has a laminated steel core,
when the voltage rises on the mains (primary) side the transformer converts the electrical
energy to magnetism. The secondary side of the transformer takes this magnetic energy and
converts it back into electricity. Maximum efficiency is only achieved if the “magnet” can be fully
charged with the maximum voltage and completely collapsed to zero – a full stroke of the
pump. If there is any DC present on the mains, as there almost always is , the pump cannot
achieve a full stroke and so full output power is not achieved. In addition to this the
transformer cores will often buzz noisily.
• Electrically and magnetically shielded casing
• 4 star wired sockets avoids»daisy chain» modulation of one component by another
• Direct maximum power, equal resistance routing to all outputs
• Rebalances the AC sine wave, removing DC components, this enables transformers to
work silently at their very maximum efficiency realising their full dynamics and power
range
• Star earthing plan avoids hum loops, reduces the noise floor, for greater silence and
definition
• Internal wiring silver plated OFC copper PTFE insulation
• Maximum Power 15Amps
