CD player metronomAfter 30 years of digital reproduction of music, in 2012 the metronom made it possible to correct technically resulting errors in the digital to analogue conversion. The new metronom picks up on the experiences of its previous model and combines them more efficiently with other analog-to-digital converter chip.
metronom high-base modules
° Channel separated double mono
° Uncompressed stereo digital signal
° TDA1540D converter in ceramic housing
° Synchronized oscillators on the TDA1540D
° Dynamic correction of the shift register
° Frequency compensation of the output stage
° Class A operation of the TDA1540D
The result of this interaction is an audible increase in spatial precision. It is no longer necessary to ask the question of deep bass registers, of nuances or transparency of reproduction - the discussion on top tonal performance is over here. Rather, new standards are set for continuity and naturalness of reproduction. Simply put, compared to the best digital playback devices, whether from CD or streaming, whether 16, 24 or 32 bits, a metronome sounds alive and authentic.
Simultaneous data formatNo compression, no artifacts and no quantization errors. The simultaneous data format is an uncompromising data format for analog conversion - while all digital playback devices available on the market use the I2S data format, which compresses the stereo channels into just one signal. With the simultaneous data format, the stereo channels are processed separately and uncompressed in a separate converter chip per stereo channel. The converters do not have to re-allocate the bundled signal to the stereo channels. Stress-free, these can fulfill their actual task, plus: negative interactions, because both stereo channels are processed in the same chip, do not occur. From digital to analog output, a channel-separated dual mono setup is possible.
Digital Analog Converter TDA1540For an analog converter that is produced without embedded filters and amplification stages, you have to use the technology of the first hour. Current chip architectures focus on industrial standards designed to reduce production costs. Converters are produced that perform a fixed static digital-to-analog conversion without repairing the resulting errors.
Dynamic conversion is only possible with a few converter chips. While the predecessor used two 16-bit converters TDA1541A, the principle of the active correction circuit metronom is now transferred to a 14-bit converter. Since this converter has a 42.86% more complex shift register structure, the TDA1540 is known for its unsurpassed natural timbre.
Active correction metronomThe converter-internal shift register, which takes over the analogue conversion of the data from the bit stream as it were as a manual transmission, is controlled by internal oscillation. Disadvantageously this happens without metronom correction with a fixed frequency and not in dependence on the received data window. Through the active metronom module on the converter, the oscillation of the shift register is dynamically adapted to the data window.
The oscillator and shift register in the TDA1540 can be controlled externally. A dynamic control depending on the data input, specifies the analog conversion in a new order of magnitude. The window size of the digital signal (14, 16, 32 bits) has no meaning for a realistic analog signal. The data of the original signal are supplied only in respective large blocks of data.
Why push back against 24/192? Because it's a solution to a problem that doesn't exist, a business model based on willful ignorance and scamming people. The more that pseudoscience goes unchecked in the world at large, the harder it is for truth to overcome truthiness... even if this is a small and relatively insignificant example.

Audio industry salesman have been promoting faster than optimal sample rates. The promotion of such ideas is based on the fallacy that faster rates yield more accuracy and/or more detail. Weather motivated by profit or ignorance, the promoters, leading the industry in the wrong direction, are stating the opposite of what is true.
