Meridian 518 Digital Audio Processor Measurements

Fig.1 D/A Processor with 20-bit resolution, waveform of undithered 1kHz sinewave at -90.31dBFS (16-bit data, 120µV/vertical div.).

Fig.2 Meridian 518, spectrum of undithered 1kHz tone at -90.31dBFS, with noise and spuriae, 16-bit precision.

Fig.3 Meridian 518, spectrum of 1kHz tone at -90.31dBFS, with noise and spuriae, 20-bit precision.

Fig.4 Meridian 518, spectrum of 1kHz tone at -90.31dBFS, with noise and spuriae, 16-bit precision, calculated from 20-bit data with 518 set to "20C16" using the "Shape B" noise-shaping algorithm.

Fig.5 Meridian 518, Bypass mode, waveform of undithered 1kHz sinewave at -90.31dBFS (20-bit data, 120µV/vertical div.).

Fig.6 Meridian 518, waveform of "digital black" with 518 set to "20C16" using the "Shape B" noise-shaping algorithm (16-bit data, 120µV/vertical div.).

Fig.7 Meridian 518, spectrum of 1kHz tone at -115dBFS, with noise and spuriae, 16-bit precision, calculated from 20-bit data using the "Shape B" noise-shaping algorithm and Gain set to "-24dB."
