Problems
with your local power supply system? Low voltages?
Power line disturbances? HF–insolation? What
does a clean power supply affect? How do interferences
get into the power supply and why can’t these
interferences simply be filtered? We will try to
answer these questions and explain how the cicable
power supply can improve the situation …
Main
distortions everywhere …
Without
electricity every high–end system remains mute,
but it often sounds bad with the normal supply.
In any case it’s noticeable that the intensity
and frequency of power supply interferences are
increasing. So why not credit the power supply it’s
rightful place of priority and create the conditions
for high–quality play back with a clean power
supply?
Too
many cooks spoil the … current!
En
route from the powerhouse to your local outlet,
many consumers use the same power supply line, with
partially devastating consequences for the quality
of the power supply line. A survey can be found
:: here.
A formerly clean sinewave nearly becomes nearly
a rectangle. The consequences are an infinite number
of odd harmonics. And that’s just ONE problem.
Every consumer [lawn–mower, microwave oven,
drilling machine, hair blower, etc.] additionaly
influences the quality of the current. You can see
it [flicker], you can hear it. Above all in the
evening, during peak demand. Just when you’d
like to enjoy music your neighbours want to pursue
their mains–operated hobbies.
Solutions
…
Until
now many manufacturers devised applications, which
solved just one part of the problem – and even
then they were usually only imperfect solutions.
So the numerous filters, conditioners, transformers,
etc. just solved ONE problem, mostly they were only
responsible for one device. The expense would have
to be doubled, trebled or quadrupled for the whole
system.
What
the PS2.4Q is NOT!
First
of all: the cicable Power Source PS2.4Q is not
a conditioner, not an isolating transformator,
not a power line filter and doesn’t
have any compensating or correctioning generator
system, even though it handles all these functions
along the way!
So
what is the cicable Power Source?
The
cicable PS2.4Q is a self–sufficient power amplifier
generating a clean sine voltage. It is built as
a linear power amplifier with a short–term
power delivery of three times its rated continuous
power.
Thereby the power source is completely secure against
overload and has extremely minimal distortions and
phase shifts between the trigger and output signal.
The damping of undesired perturbations is more than
110dB, which makes subsequent power filters obsolete.
On the contrary these types of filters normally
make the sound of connected devices worse.
Apart from »classical« phenomena [voltage
fluctuations, harmonic distortions] the design ensures
that critical high frequency bursts and spikes are
also excluded. Conceptually the cicable Power Source
fulfils the following functions:
| |
 Constant
voltage
The voltage should
be independent from load current and should
always deliver the same voltage without
a regulation delay.
Constant
frequency
The power frequency
should be exactly as specified without
a regulation delay.
Power–Conditioning
Power conditioning
meaning the voltage is free from DC offset:
the sine voltage doesn’t have an offset
in comparison to the zero crossing.
Power
DropOuts
Uninterruptible
power supply up to 100ms at 100% interruption;
up to one period with shorter interruptions.
Overvoltage
protector
As a result of its
construction, overvoltages on the power
supply input are completely eliminated.
One advantage is that high grade audio
components are protected from expensive
surge damage.
High
frequency supression
High frequent interferences,
external, internal, caused directly or
indirectly, can be eliminated. Further
filters with all their disadvantages are
not necessary.
Low
distortion
Even order distortion
[a multiple of the line voltage frequency]
and – odd – distortions [result
of a non sine voltage] are at least 80dB
below the fundamental at all operating
conditions – this equates to 0.01%
distortion.
Independence
from other consumers / loads
The power supply is completely decoupled
from other consumer load. [Load regulation
is due to the low output impedance better
than 0.1%].
Compensation
of apparent output rate
The
inductive and capacitive power rates are
fully compensated by the functionality
of the cicable Power Source, keeping the
sine voltage clean. The claimed low distortion
can be achieved only this way. [Functioning
by the »four–quadrant–principle«] |

One
for all, all for one …
The cicable PS2.4Q serves your whole hifi system
and doesn’t just improve single devices. So
the buying of several power sources of different
power ratings is not necessary. It is constructed
to create sufficient power for 95% of all system
configurations. And if it’s still not enough,
well… there are much bigger models.
One–way
street
Power line interferences affect every consumer load
and don’t use ‘one–way streets’
to spread. They’re looking for access by any
path, mostly where less resistance is to be found;
interferences criss–cross the power lines.
So optimising one single component of your system
is of no use, because the other components lead
their interferences back to the »clean components«.
Assistance comes from the mean 0,1% load regulation
of the cicable Power Source, acting like a stop
sign: »no admittance« !
What
does the PS2.4Q deliver?
As
Rolls–Royce would say: enough! – But seriously,
the cicable Power Source supplies 2000 VA at normal
operation, in intermittent operation even 6000 VA.
This should be enough for bigger hifi–systems
with high–performance power amplifiers. We
experienced that even big mono power amplifiers
don’t utilize more than 1000 VA, and here we’re
talking about 500W power rating your speakers have
to transform into sound.
Technical
consequences ...
The
consequences for the performance of your hifi components
is huge. The constant supply voltage means an increase
of about 10% or more of the amplifier’s output
capability. The reduced distortion factor additionally
improves the sound quality. With some mono power
amplifiers we measured 20dB less distortion. These
design parameters can only suggest the improvement
of all high end components.
How
it sounds like ...
The
outstanding technology results in sound improvement,
too. Without any compromise, the cicable Power source
enhances every hifi system. See for yourself by
which means the sound improves:
improved
voice reproduction
natural
sound reproduction
less
listening – stress
more
dynamics
increased
transparency
improved
stereo image
less
graininess
greater
differentiation of timbres
more
detail
crystal
clear and silky reproduction of tone pitches
The
scale and the nature of improvement is surely also
dependant on other connected devices and their mutual
manipulation. The power reserves and the concept
permit a trouble–free exchange of single components,
so you don’t have to reconsider the decision
for a new power supply in the light of new audio
components.
