11. Special Features of the Digital Output Apart from the audio data itself, digital audio signals in SPDIF or AES/EBU format include a header containing Channel Status information. False Channel Status is a common cause of malfunction. The DIGI96 series ignores the received header and creates a totally new one for the output signal. Note that in record or monitor modes, set emphasis bits will disappear. Recordings originally done with emphasis should always be played back with the emphasis bit set! This can be done by selecting the ‘Emphasis’ switch in the Settings dialogue. The changes in sound caused by this setting can be monitored in real-time at the analog output jack. At 64, 88.2 and 96 kHz sample rate the analog output does not support De-Emphasis, so no change in sound will be audible. The DIGI96 series' new output header is optimized for largest compatibility with other digital devices: • 32 kHz, 44.1 kHz, 48 kHz, 64 kHz, 88.2 kHz, 96 kHz, depending on the current sample rate • Audio use, Non-Audio • No copyright, copy permitted • Format Consumer or Professional • Category General, generation not indicated • 2-Channel, No Emphasis or 50/15 µs • Aux bits audio use Note that most consumer-orientated equipment (with optical or phono SPDIF inputs) will only accept signals in ‘Consumer’ format! The status 'Professional' should always be activated when using AES/EBU format (when the XLR connectors are used). The audio bit in the header can be set to 'Non-Audio'. This is necessary when Dolby AC-3 encoded data is sent to external decoders (surround-sound receivers, television sets etc. with AC- 3 digital inputs), as these decoders would otherwise not recognize the data as AC-3. When playing back in multi channel mode (using the optical ADAT interface) the XLR and coaxial connectors will be turned off. This prevents sound disturbance by the ADAT signal fed to SPDIF or AES/EBU inputs. User's Guide DIGI96/8 PAD © RME 18
12. Notes on the ADAT Interface DIGI96/8 PAD comes with two different driver methods in one driver. Using channel interleave there is only one device, the software in use divides the channels into 8 mono tracks. Because this easy to handle 'Windows native' method is not widely used the DIGI96/8 PAD also supports Multi-Device operation. The driver routes the 8 tracks in 4 stereo devices. These 4 stereo devices can be used by nearly any software to record or playback more than 2 channels simultaneously, making DIGI96/8 PAD compatible to a wide range of already existing software. DIGI96/8 PAD includes an intelligent hardware controller for ease of use. Whenever more than 2 channels are used, no matter with record, playback or both, the card switches into ADAT mode. Whenever an ADAT signal is present at the optical input the settings dialog of the DIGI96/8 PAD indicates ‘ADAT 44,1 kHz' or 'ADAT 48 kHz'. If now the output function is set to ‘Input’ while AutoSync is active the card's output changes to ADAT mode to allow input monitoring of up to 8 channels. The analog output allows you to listen to any of the four stereo pairs. The desired pair can be selected in the 'Track' field of the Settings dialogue. If the software being used requires a continuous ADAT mode activate the switch ‘Force Adat' in the Settings dialog. When using a 'normal' 2 track program to play or record a stereo file, you're not only able to send the data to any SPDIF device but also to any other ADAT interface! Just activate 'Force Adat' and choose the stereo pair that corresponds to the desired channels (for example DIGI96/8 PAD (3+4)). In SPDIF mode it doesn't matter which stereo device is being used. 13. Multiclient Operation 13.1 General The DIGI96/8 series supports multiclient operation. That means more than one program can be used at the same time. But this mode is only available as long as certain rules are followed. For a flawless multiclient operation with multiple programs the below guidelines have to be followed precisely. Rule 1: Multiclient operation always requires the activation of Force Adat! After an activation of Force Adat all 4 output pairs can be used freely. You can use 4 different MME programs, or two stereo pairs under ASIO, one under GSIF and one under MME – any combination is allowed. Rule 2: Multiclient operation always requires identical sample rates and bit resolutions! It is not possible to run one program at 44.1 kHz and another one at 48 kHz. Also it's not possible to run one program in 16 bit and another one in 24 (32) bit resolution. Please note that the selected latency (Mode) also sets the bit resolution for GSIF and ASIO!
