Highlights
1.1
DSP (Digital Signal Processor)
A powerful DSP performs the calculations for the upsampling to 24Bit, 352.8kHz
(or 384kHz). The DSD data of a SACD is converted into PCM format during the upsampling process. The converted data is extrapolated by a polynomial algorithm.
Additionally this DSP performs computations for the volume control and the balance
settings. Thanks to its 32Bit floating comma architecture these calculations go
without the usually increase of the quantification noise.
1.2
The soulution 760 D/A-converter incorporates the unique and innovative, DSP
based Zero-Phase-Technology. Every digital to analog converter requires an analog
low pass filter in its output in order to suppress high frequency noise and aliasing
signals, which adds phase shifts for higher frequencies. Despite its relatively high
cut-off frequency of 120kHz, the analog 3rd order Bessel-filter of the 760 shows a
phase shift of up to 15° in the audio band. A powerful DSP does pre-correct these
potential phase errors in the digital signal. Once the signal passes the D/A converter
stages and its related low pass filter these errors get cancelled out. The phase error
of the resulting analog music signal remains below 1°, 20Hz - 100kHz! The ZeroPhase-Technology brings you even closer to the beauty of the source material!
1.3
Clock
Utmost precision of the clock signal is a must have for a top class D/A-converter.
Lowest phase-noise behaviour is by far more important than long term frequency
stability. Together with experts in the field of highend oscillators we did develop a
TCXO which is optimized for this application. It does not run on its first harmonic
but on its 3rd overtone. The clock modules work at frequencies around 100MHz, this
requires extremely fast amplifier stages within the oscillator loop but allows achieving best results regarding phase-noise. Even the best OCXOs or rubidium based oscillators are not able to outperform these specifications. The 760 DAC does have a
separate oscillator module for signals based on 44.1kHz and signals based on
48kHz.

D/A-converter
User manual
760
Synchronisation to an external clock signal would deteriorate the performance of
these oscillator modules significantly. Therefore the 760 does not provide any
clock-input. However, external components can be synchronised to the high quality
clock signal through its clock-output.
1.4
Digital/Analog-Converter
The D/A converter section as well as the analog output stages are done in dual mono
layout. Only the top quality converter section of the Burr-Brown 1792 DAC chip is
used. The internal upsampling section is bypassed! Four extremely fast (80MHz) I-V
converters per channel transform the output sensible currents of the DAC chips in
voltages before they get filtered in the following stage. This ensures optimal conditions in the filter stage as well as for the I-V converters.
1.5
Output stage
The output stage is optimised for velocity, precision and impulse current rating. It
works with an internal bandwidth of more than 40Mhz. Thanks to its low output impedance of 2 and Class-A operation the output stage is stable on every load (also
long cables are driven without problems). Its theoretical peak current rating of 3A is
limited to 1A.
1.6
Power Supply
The 760 D/A-converter has two strictly separated power supply units for the digital
and analogue sections of the unit. This ensures lowest mutual interferences between these two sections. The supply voltages for the analog section are stabilised
in several stages for minimal deviations. More than 500’000 microFarad of storage
capacitance combined with extremely fast and precise voltage control stages ensure
optimal current peak ratings.

User manual


Follow the safety advices
Keep this user manual.
Mains supply
Exclusively use 3 phase power cords with ground conductor.
Unplug the 760 from the mains in the following cases:
 before you manipulate with cables
 before cleaning
 during thunder storms
 before you leave for longer periods
Cabling
While manipulating with cables the 760 has to remain disconnected from the mains. Wrong cabling may cause damages to
your 760, (pre)amplifier and loudspeakers. Excessive volumes
due to inappropriate handling may cause hearing damages.
Transport
Use only with the cart, stand, tripod, bracket or table specified by
the manufacturer or sold with the apparatus. When a cart is used,
use caution when moving cart/apparatus combination to avoid
injury or tip over.
Packing
In order to omit condensation of water inside your 760, let it
warm up within the packing.
Please keep the original packing for future transports.
Operation
Never run your 760
 with opened housing
 with closed cooling-slots
 with high ambient temperatures (>40°C)
 close to heat sources like radiators, etc.
 with extremely high humidity for example in humid cellars
 close to water (Sink, bathtub, or similar equipment)
Cleaning
Use a soft and dry towel. We suggest using a nonabrasive microfiber towel. Please do not use any solvents or liquidities
Service
Service by a qualified person required if
 the mains-cable or the mains connectors are damaged
 foreign substances or liquidity have entered the 760
 the 760 has seen rain
 the 760 seems to malfunction
 the 760 has fallen to the floor or the housing is damaged

Due to the extraordinary load-stability of the output-stage also long cables can be
used with no reduction of sound quality. For long cables we recommend using the
balanced connectors. For short cable lengths also unbalanced cables represent a
high quality connection, top quality cable and optimal layout prerequisite.
