A prestigious heritage
The legendary Nagra recorders
Nagra is one of the most respected names in the
world of audio. This Swiss company invented, in
1951, the first portable recorder for professional
use. A machine whose features and exceptional
sound quality revolutionised the art of sound recording all over the world. Generation after generation,
Nagra recorders have stood for excellence in their
field, constantly reinforcing the legendary status of
the brand.
Throughout its history, Nagra has received a
great number of distinctions, many of them highly
prestigious, including three Oscars® and an Emmy®
Award.
For ten years, Nagra has also been present in the
sector of high-end equipment aimed at audiophiles.
This development has been welcomed by aficionados wanting access to products conceived outside
conventional norms and without compromises.
At Nagra the same engineers develop equipment
for both the professional and the high-end range.
The same extremely high standards are applied to
the whole production.
The new range of Nagra CD players is a pure
expression of the spirit of Nagra. It is born of
several developments, mechanical and electronical, already tried and tested in the company’s
recorders.
It boasts many innovative features offering a previously unattained level of performance.
Nagra is one of the world’s most decorated audio company.
In particular, it has won three Oscars® and an Emmy® Award.

CD players in the Nagra range
Absolute respect for original sound recordings
Whether in a concert hall or a studio, Nagra is the
ultimate yardstick for professional sound recordists
seeking to make a recording as close to the original
as possible.
With Nagra CD players, you are able to enjoy this
sound, reproduced with perfect integrity, in your own
system.
In their engineering and electronics, Nagra CD
players set new standards of precision, accuracy
and robustness. Engineers have applied a range of
solutions aimed at preventing any deterioration in the
signal, all the way from reading the data on the disc
to final output from the machine.
Special in-depth work has been carried out to solve
problems of synchronisation drift (jitter), which typically affects even the best-constructed machines. The
results obtained here are spectacular, with negligible
values.
An equally rigorous approach has been applied to the
construction of circuits, the choice of components and
production tolerances. Design consistency ensures
exceptional quality.
Great, authentic Nagra sound: a quality which is immediately visible or rather, audible. Never before have
CD players reached such levels of clarity, sharpness
and natural sound.

Nagra CDC, CDP and CDT
Exceptional machines combining efficiency, durability and precision
The range of Nagra CD players comes in three
versions:
- The Nagra CDC, equipped with volume and balance
controls operating on preamplified analogue outputs.
This means the equipment can be connected directly
to a power amplifier.
Another special feature of this model is the double
modulometer on the front panel, which allows the
monitoring, on each channel, of the signal as it is
recorded on the disc.
-
The Nagra CDP, which has a fixed level analogue
output. The digital-to-analogue converter circuit is
identical to that of the CDC model.
The Nagra CDT, designed for use with an external
-
digital-to-analogue converter such as the Nagra DAC.
The front and rear panels are similar on the CDP
and CDT models.
The brushed aluminium case has the same
dimensions as the Nagra PL-P and PL-L
preamplifiers.

«Nagra monoblock tray» unit
Worthy of a Swiss timepiece
Nagra CD players are equipped with a frontloading motorised drawer system, which is more
practical than the top-loading solutions. However,
this entire system has been rethought. Called the
“Nagra monoblock tray”, it features a CD module
mounted directly onto the drawer itself, forming a
moving unit.
Built with the same care and attention as a Swiss
timepiece, this monoblock unit is particularly
sturdy and stable. It provides an ideal mechanised
environment for the CD module, a top-of-the-range CD-Pro2M model, to display its full capacity.
The drawer moves on high-precision slides: this
achieves a tolerance of only two microns with
plenty of smoothness.
Engined aluminium pieces
The drawer is activated by a state-of-the-art planetary reduction motor: a component developed by a
NASA-approved supplier, whose products equipped the Mars Rover robot sent to the red planet.
The magnetic clamp that sits on the disc has
also been manufactured by Nagra to improve centring and positioning of the CD on the transport.
The prescribed weight of this component has been
rigorously adhered to; an over-heavy roller would
deteriorate the playback and wear the transport
motor out prematurely.
The back of the drawer has a diode strip which
illuminates the CD when the drawer is opened.
This allows the player to be used in reduced light.

Sturdy, ultra-precise, the “Nagra monoblock tray” unit ensures perfect reading of
the disc, the starting point for accurately reproducing the original recording.

Neutrality and clarity
A typically Nagra signature
Nagra CD players are the ultimate reference in terms
of electronic engineering and quality of execution.
The signal extracted at the CD module output is
completely resynchronised via a PLL (Phase Locked
Loop) and a VCXO high-precision oscillator (Voltage
Controlled Crystal Oscillator). This reduces dramatically the jitter and the manufacturer code of the disc
– data engraved on the CD – retains its integrity.
The digital signal is conveyed symmetrically,
eliminating earthing problems. It is received and
oversampled by a Burr-Brown digital-to-analogue
converter with very low-level noise and distortion.
The printed circuit holding the converter is protected
against radiation by a gold-plated metal cover.
In order to avoid disruptions linked to the power
supply, which is often very polluted, there are no
high voltages or alternating currents inside the
machine. The constant +12V voltage, from which
the other 8 voltages needed by circuits are derived,
comes from an external supply box. These voltages
are produced by similarly low-noise converters. They
are synchronised with the CD module clock.
These technologies, which guarantee perfect clarity
and exceptional sound reproduction, are the direct
results of solutions developed for Nagra recorders.
The same applies to the choice of components,
originating from the best sources and selected on the
basis of listening tests.
Nagra CD players use an external power supply, just like the PL-P and PL-L preamplifiers.
Circuits are thus protected from disruptions caused by the power source.

Nagra CD player’s ergonomy is based on the same philosophy as
Nagra professional recorders. The connection panel is complete
and can be placed on the rear panel or the right side of the unit. It
includes symmetric and asymmetric analogue outputs, as well as
AES, S/PDIF and Toslink (optical) digital outputs.
