High definition digital-to-analogue converter
The DAC is a high quality digital to analogue converter, equipped with remote control and designed to convert the digital signals, up to 192 kHz sampling frequency, to the purest analogue audio levels to feed directly into a power amplifier or pre-amplifier. The DAC offers over sampling and 24 bit conversion. The DAC has inherited the fabulous electronic design of the Nagra
D and Nagra V digital recorders used by the most prestigious music
companies and recording engineers in the world. These exceptional
machines have convinced the engineers that digital audio could
convey the emotion and warmth of analog tape recorders and long
play disks that they miss with other digital formats.
The DAC was
designed with the same ingredients and philosophy to provide you
with state-of–the-art technology respecting
The Nagra DAC is the result of 50 years of experience in high-end
audio technology. As other Nagra products, it ignores all compromises
Nagra has already demonstrated that whatever the technology – tube
or solid state – its products offered ultimate musicality
and transparency. With the DAC, this philosophy now extends to
the digital Hi-Fi world.
Far more than a converter
The Nagra DAC is far more
than a converter. Its many technical and innovative features will
significantly enhance the performance of your system:
High-End Audio the DAC provides a 192 kHz 24 bit up sampling to
all incoming signals. Even 16 bit resolution formats such as CD
enjoy a smooth and elegant signal conversion.
- Extensive digital and analog input /output formats
- Volume and balance control
- 192 kHz/24 bit capable with 192 kHz 24 bit up sampling to
any input signal
- Jitter free ATF module
- Phase reverse
- Easy settings and operation with interactive keys
- Remote control Unit (Nagra RCU)
- Large back lighted display with automatic intensity adjustment
- LED displays for volume, balance and level indications
- Software upgrades with RS232 port
The DAC features an
ATF (Adaptive Time Filtering) module that increases the quality of
all signals just before the conversion stage by eliminating the jitter.
of the art technology
The electronic circuit boards are made up of four layers. As no
computer-assisted software design meets our demanding specifications,
the tracks are conveniently routed to keep the integrity of the
signal. The signal-to-noise ratio is very large and inter-channel
crosstalk has been maintained at the lowest possible level.
The DAC features Nagra’s Remote Control Unit. It allows access
to all parameters, including navigation into the menu. In addition
one RCU can control other Nagra devices like MPA and PL-L.
The DAC offers both electronically balanced outputs on XLR and
unbalanced on RCA. Optional custom-designed Nagra-made transformers
are also available for floating output.
7 different inputs can be selected as well as
the main volume and balance adjustments.
|A large LCD screen
permits an overview of the selected input signal as well as
the automatic settings, number of bits, output level, etc.
The same LCD screen in combination with the 5 function keys
allows surfing through the different menus. Settings like contrast,
back light level, LED brightness, etc. can be manipulated.
the left side of the LCD screen, the automatic selected sampling
frequency is shown by the corresponding LED.
green cross on the second panel gives a clear overview concerning
the adjustments of the output level and the balance position.
Two bar graphs indicate the audio output level. The arrow keys
give direct access for adjustment of the volume and balance.
From the main menu, the brightness of the LEDs can be
selected as well as the choice of lights for bar graph or dot
