The soulution 541 SACD-Player 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 sig-
nals, which adds phase shifts for higher frequencies. Despite its relatively high cut-
off frequency of 120kHz, the analog 3
rd
order Bessel-filter of the 541 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 Zero-
Phase-Technology brings you even closer to the beauty of the source material!

Clock and PLL (Phase Lock Loop)
Utmost precision of the clock signal is a must have for a top class D/A-Conversion.
Synchronisation to external digital data requires a clock/PLL that must adapt itself
very fast to eventual changes of the external data.
1.7
Output stage
The output stage is optimised for velocity, precision and impulse current rating.
Thanks to its low output impedance of 10
W
and Class-A operation the output stage
is stable on every load (also long cables are driven without problems). The output
stage is a completely symmetrical design.
1.8
Power Supply
The Digital-Player 541 has two strictly separated power supply units which are
combined with a multistage filtering network for lowest mutual interferences.
The supply voltages for the analog section are stabilised in several stages for mini-
mal deviations.
