Technical information
All circuits are constructed with the shortest possible signal paths to
ensure best high frequency characteristics. Because of using SMD
techniques and both side component equipping, all circuits have a high
functional density.
In order to prevent electrical interference, digital and analogue section are
completely separated and work together by lighting wire. The voltages
for each unit are prepared and regulated separate.
Altogether five integrated, 14 discrete built up main regulators and
further eight pre regulators are in use.
The filtering of the digital data is performed by a program-controlled
signal processing system. It is equipped with six filter types. The six
filters represent the latest state of filter technology. The asymmetric filter
developed by Audionet combines the merits of all filter types without
accepting their disadvantages for the first time.
The DAC is completely decoupled from the clock of the signal source.
The internal clock is generated by two temperature regulated quartz
oscillators. The digital data is read out of a dynamic 2 megabit buffer
memory. A fast signal processing system checks and controls buffer and
temperature regulation circuit.
A 1 bit D/A-chip converts the data with 20 bit accuracy and 196 times
oversampling.
The reproduction of the analogue data is effected separate for each
channel by six especially developed and optimized discrete SMD
operational amplifiers. Tonal distortions are reduced to a level, that can
hardly be measured and quite even not hear.
