CEC PH-53 PHONO STAGE MM / MC
To PH-53 PHONO Stage της CEC ειναι πληρως εξοπλισμενο με ολες τις ρυθμισεις με dip-switches και με την καινοτομια current injection χωρις αναδραση που εκμεταλλευεται το ασθενικο ρευμα της κεφαλης και οχι την ταση. Ταιριαζει με ολες τις κεφαλες MM & MC και προτεινεται η balanced συνδεσμολογια με την κεφαλη για μηδενισμο του θορυβου και την μεγιστη αναλυση του σηματος . Η ποιοτητα Ηχου βρισκεται σε αριστα επιπεδα. Ανταξιο των καλυτερων κεφαλων MC .

PH53 is a state of the art phono amplifier. The unique balanced current injection input for a wide range of MC cartridge and the LEF amplifier technology for the output stage provide today's top level sound quality. Also standard RCA input for unbalanced use with MM or MC cartridge is available. All amplifier sections run without any overall negative feedback. Thus the amplifier creates no dynamic distortion.
Matching with every cartridge
PH53 is compatible with both MM and MC cartridges and
allows precise settings with DIP switches on its bottom panel. Input capacity
for MM cartridge is adjustable to around 47pF to 884pF with 4 switches per
channel in addition to cable capacitance. Also input impedance is adjustable to
100Ω that is a common value for most MC cartridges or to 1kΩ that is a standard
value for most high output MC cartridges.Input impedance for MM cartridges is
fixed at 47kΩ with all the switches open.Gain switches are also applied
increasing the gain by 6dB for low MM and high MC, or 20dB for low MC.
*inputs include jacks for XLR balanced current
injection or unbalanced RCA.Output signals are always available balanced and
unbalanced,regardless of the input.
*Always use one input only!
State-of-the-art Current Injection technology
Current Injection is a landmark technology for shortening
the signal path, improving the sound quality and measurement specs
significantly. The effective simplicity of Current Injection requires a
non-feedback-loop amplifier. While Current Injection replaces the voltage
amplifer, LEF guarantees best performance of the current amplifer with low THD.
Both technologies complement each other and overcome the limitations of
traditional circuitry to a better standard of music reproduction. This is
applicable when using balanced MC input.The maximum performance of MC cartridge
is attained because neither a redundant amplification stage nor negative
feedback are present in this method,and an outstanding capability for musical
expression is achieved without sacrificing measurement specs.
*Not applicable for RCA input.
CEC's unique LEF circuit
DA53 features CEC's unique LEF(Load Effect Free) circuit
that virtually eliminates the causes of musical degradation. High efficiency is
achieved with this LEF circuit along with the acquisitionof delicate, subtle
sound reproduction. The music reproduction appeals to senses,forgetting about a
performance of technical squipment.The original sound is reproduced in highest
fidelity.
RIAA equalization with the Neumann extension
PH53 uses RIAA equalization with Neumann extention. The
Neumann time constant or some equivalent is used on almost all recordings. RIAA
with the Neumann extension allows a wider top frequency extension.According to
the RIAA the frequency response drop down from 20kHz on. Beyond 20kHz the
Neumann character shows a gradual decline and then flat.
PH53 also has a subsonic filter for preventing large woofer excursions and muddiness in the midrange due to mechanical vibration noise signals that are found below 15Hz. You can select from two different downward curves, soft and maximum reduction.
