Descrierea produsului
CP-800
este un preamplificator/procesor de sunet stereo, care combina
functionalitatileunui preamplificator analogic conventional cu cea a
unui DAC (digital to analog convertor) cu multiple intrari, dotat cu
functionalitati de procesare digitala a semnalului. Combinarea acestor
functii intr-un singur echipament permite economie de spatiu,
cabluri si circuite (ceea ce reduce costurile), scurteaza traseul si
pastreaza calitatea semnalului audio. Capabilitatile de procesare cum ar
fi EQ parametric, bass management, tone control, au menirea sa
imbunatateasca performantele acustice a sistemului compensand sau
diminuand neajunsurile incaperii sau a pozitionarii inadecvate a
boxelor. Punctul sau forte il reprezinta intrarea asincrona USB izolata
galvanic, atat cea frontala, cat si cea de tip B pentru conectare la
PC/Mac, ceea ce permite reducerea zgomotului si a jitter-ului la minim. Astfel se obtine un sunet caracterizat printr-o claritate si scena nemaintalnita la sursele care redau fisiere digitale. The vast majority of high end preamplifiers available today are
direct descendents of products that have been made for decades, rooted
in an all-analog world. The CP-800 is something new. It combines key
building blocks of a contemporary high-end audio system in a unique way
to improve and shorten the signal path. New technologies are applied to
realize the benefits of modern computer-based audio. Now, a CD ripped to
a computer can sound better than if played in a CD player; convenient
and feature-rich access to your music library is possible with
state-of-the-art playback; a Class-designed Switch Mode Power Supply
(SMPS) with Power Factor Correction (PFC) delivers higher performance at
a lower price; there is no compromise at an affordable price. And there
is much more
Streaming/AirPlay
A rear panel Ethernet connection offers streaming
options including Apples AirPlay and DLNA, where sources benefit from
special handling to accommodate files up to 192 kHz with the CP-800s
own oscillators controlling timing for D-to-A conversion. Convenience
never sounded so good.
IP Control
When connected to your home Network, the Class App
(available free of charge in the Apple App store) running on Apple iOS
devices offers a sophisticated alternative to the IR remote.
USB
Having a dedicated computer in your listening room
doesnt have to mean noisy fans and bulky monitors. Simple solutions
like Apples Mac Mini or an inexpensive laptop can be installed out of
site and operated remotely. Connect by HDMI to your TV, use a wireless
keyboard and mouse when necessary and connect to the CP-800 by USB for
audio, then control with an iOS device, Smartphone or tablet. Classs
unique implementation of asynchronous USB audio will render
studio-quality sound from properly ripped CDs and high-resolution music
downloads up to 192 kHz.
Bass management
No matter how well your speakers reproduce bass, they
are almost certainly not located in the optimum place in your room to do
so. The interaction of your speakers and the room will result in signal
cancelations or dips at certain frequencies at the listening position;
no amount of EQ can solve this problem. The solution is mono or stereo
subwoofers, outputs for which are available from the CP-800 with
selectable crossover frequency and slope in the digital domain. The
result is deep, smooth bass response without adding analog circuitry to
the LR channel signal paths.
PEQ
Regardless where your speakers, subwoofer(s) and
listening chair are in relation to each other, there will likely be room
modes that can only be addressed with equalization. In most rooms, the
three primary dimensions contribute to three low frequency modes where
the room actually increases the level causing peaks at those
frequencies. The CP-800 offers parametric equalization to help address
these real world problems. Performed in the digital domain, these high
quality filters allow optimization of low frequency response without
adding analog circuitry to the LR channel signal paths.
Tone Control
Banished from legitimate high-end preamps since the
sixties, the tone control makes a come-back in the CP-800, but with a
modern implementation. Tone controls typically mean additional analog
circuitry in the signal path. The CP-800 introduces a flexible tone
control feature that is entirely digital. If youve ever wanted to
soften a recordings top end a little or add a little warmth, you will
appreciate the convenience and subtlety of the CP-800s Tilt tone
control feature. After more than forty years, the tone control is back,
and now it works properly and without compromise.
Analog quality
Make no mistake, the CP-800 is also our best analog
preamplifier; with fully balanced circuitry and completely isolated
symmetrical left and right channels, your analog sources will sound
better than ever. The CP-800 makes digital processing available to all
sources, but when you want pure analog, the Digital Bypass option
switches off the digital clocks while the CP-800 handles the signal in
the analog domain.
Have it all
The CP-800 puts world-class performance into one
flexible and attractively priced chassis. Separate CD players and USB
DACs require additional circuitry and interconnect cables plus a
separate analog preamp, giving the CP-800 an obvious comparative
advantage in both performance and value. The additional features like
Bass management, PEQ and Tone Control make better real world performance
a reality. If you are building a no-compromise high-end audio system,
the CP-800 is unique. It is the first and only preamp/processor that
