# Precision power supplies # 32-bit 384KHz DAC # PC-drive mechanism # Very low jitter PLL generator


The PC-drive mechanism tilt compensator and an ultra dynamic resonance absorption system.

The CDP-15 clearly demonstrates how much music is buried in compact discs, retaining the inherent musicality of the original.

Lyrics have intelligibility, instruments are focused in a spacious and airy soundstage.

When things get loud everything hangs together, without glare of harshness, because distortions are absent.

Digital audio depends on the proper signal being reconstructed at precisely the right time.

Any late or early digital sample distorts the audio waveform, causing it to sound harsh and unnatural.

The CDP-15 delivers these samples with adequate precision and low distortion.

All controls are accessible only via the remote control.

The Texas Instruments PCM5122 and the PLL generator are placed in the DAC stages.

To CDP-15 δείχνει καθαρά πόση μουσική είναι κρυμένη σε ένα ψηφιακό δίσκο, διατηρώντας την εγγενή μουσικότητα του πρωτότυπου.

Οι στίχοι γίνονται κατανοητοί, τα όργανα είναι εστιασμένα σε ευρύχωρη και διευρυμένη ηχητική σκηνή.

Όταν η ένταση ανεβαίνει όλα διατηρούν τη συνοχή τους, χωρίς περιττή λαμπρότητα ή σκληράδα, καθώς οι παραμορφώσεις απουσιάζουν.

Ο ψηφιακός ήχος στηρίζεται στην αναδόμηση του σωστού σήματος, ακριβώς την ορθή χρονική στιγμή.

Κάθε καθυστερημένο ή πρόωρο ψηφιακό δείγμα παραμορφώνει την ηχητική κυματομορφή, προκαλώντας σκληρό και αφύσικο ήχο.

Το CDP-15 επεξεργάζεται αυτά τα δείγματα με επαρκή ακρίβεια και χαμηλή παραμόρφωση.

Όλα τα ρυθμιστικά είναι προσβάσιμα μόνο από το τηλεχειριστήριο.

*** The Texas Instruments PCM5122 is a 32-bit DAC, which corresponds to high-performance, high sound quality digital audio systems.

Internal circuits includes newly developed 32-bit digital filters for better sound quality and a DSP.

It has increasing performance for systems with excessive clock jitter and accepts up to 384kHz PCM data.


SNR: 112db

THD+noise@-1dbFS: -93db

Audio data formats: 16-bit to 32-bit

Sample rates: up to 384KHz

** TCXO or temperature compensated crystal oscillator.

A crystal oscillator uses the mechanical resonance of a vibrating crystal to create an electrical signal with a precise frequency.

The clock is stable at ±1ppm.


Stability: ±1ppm

Phase noise: –90dbc/Hz@ 10Hz, -120dbc/Hz@10KHz


* The PLL or phase-locked loop is an electronic circuit with a voltage or voltage-driven oscillator that constantly adjusts to match the frequency of an input signal.

Clock output achieve the very low-jitter performance needed for the high performance audio DAC.

The PLL is clocked by a low phase noise TCXO**.


Clock Jitter: 50ps.

Multiple Sampling Frequencies: 32, 44.1, 48, 64, 88.2, 96kHz.
