12.3.1 AES-EBU without SRC
• 24 channels of 24-bit digital input over 12 AES EBU pairs.
• 24 channels of 24-bit digital output over 12 AES EBU pairs.
12.3.2 AES-EBU with SRC on 8 channels
• 24 channels of 24-bit digital input over 12 AES EBU pairs.
• 24 channels of 24-bit digital output over 12 AES EBU pairs.
• 8 (out of 24) channels feature SRC (Sampling Rate Converter) up to 192 kHz (96 kHz on AES v.1) either on input or on
output.
12.3.3 SDIF
• 8 channels of 20-bit (PCM) or 8 channels of 64-bit (DSD) digital input & output over 2 SDIF cables (connected to 2 DB25).
12.3.4 TDIF
• 24 channels of 24-bit digital input & output over 3 TDIF cables (connected to 3 DB25).
The table below is a summary of the different possibilities allowed with these 4 daughter cards @ 1FS.
The AES with SRC provides 6 (Sony mode) or 4 (P3D mode) I/O of DSD channels through connectors Rear 0 and Rear 1. The AES
without SRC provides 8 (Sony mode) or 6 (P3D mode) I/O of DSD channels through connectors Front, Rear 0 and Rear 1.
In XDTDM mode, the SDIF daughter card offers now (from Pyramix version 5.1) 8 In and Out channels in DSD & PCM
mode. In HDTDM mode, no SDIF I/Os are available, neither in PCM, nor in DSD mode. Note that this daughter card does not
use the Rear 1 connector and does not support Sample Frequency higher than 1FS.
The following figure represents the configuration of the Mykerinos bracket when combined with one of the AES, AES II, SDIF or
TDIF daughter cards.
