The base model Digi32 has +digital input and output (both optical and RCA connectors). It supports +16/20/24 bit full duplex recording and playback with standard S/PDIF +devices. Digi32 Pro has added 20 bit analog output and it supports up to +96 kHz sampling rates. It also has XLR connectors for AES/EBU unput and output. +Digi32/8 is Digi32 with added support for ADAT compatible 8 channel optical +digital link. + +The Digi32 family is also sold as the PRODIF family by SEK'D. However some +SEK'D PRODIF models are not made by RME and they will _not_ work with OSS. +In particular "Prodif32 Plus" is _NOT_ supported by OSS. + +More information about these cards can be found from +http://www.rme-audio.com/english/ and http://www.sekd.com. + + RECORDING AND PLAYBACK + +Basic recording and playback functions will work like with any other +soundcard. However there are few things to note due to digital nature of +the cards: + +o Only 16 and 24/32 bit audio formats are supported. +o Only few sampling rates are possible. All Digi32 family members support + 32kHz, 44.1kHz and 48kHz sampling rates. In addition Digi32 Pro supports + 64kHz, 88.2kHz and 96kHz. +o When the device is opened for input or input/output access the sampling rate + will be locked to the input signal in the selected port. Opening the device + will fail if there is no valid signal connected to the input port. + + MEMORY USAGE + +By default the Digi32 driver will allocate 64k of buffer both for recording and +playback functions. This should be sufficient in most cases. If necessary +the buffer sizes can be increased by defining digi32_buffsize in the +oss_digi32.cfg file (in the directory you installed OSS). For example +digi32_buffsize=128 setw the buffer size to 128k. + + MIXER PANEL + +There are few settings that can be changed using the ossmix program +shipped with OSS. Note that these settings should not be changed +while recording and/or playback is active (otherwise results may be +inpredictable). The changes will take effect when playback/recording +is started next time. + +The following settings are available: + +o digi32.deemph ON|OFF (currently OFF) +Enables digital de-emphasis. Only available with Digi32 Pro. + +o digi32.sync <EXTERNAL|INTERNAL> (currently EXTERNAL) + This setting can be used to select between internal and external sync + source during playback. External sync will always be used when the device + is opened for recording. + +o digi32.aesmode <CONSUMER|PRO> (currently CONSUMER) + This setting can be used to switch between the consumer and the pro modes + on the S/PDIF port. Not available with Digi32/8. + +o digi32.mute ON|OFF (currently OFF) + This setting can be used to mute the card. + +o digi32.input <OPTICAL|RCA|INTERNAL|XLR> (XLR only on Digi 32/PRO) + This setting is used to select the active input. Note that XLR is supported + only by Digi32 Pro. + +OPTIONS +o digi32_buffer_size=<64..128> +By default the Digi32 driver will allocate 64k of buffer both for recording +and playback functions. This should be sufficient in most cases. If necessary +the buffer sizes can be increased. + +FILES +CONFIGFILEPATH/oss_digi32.conf Device configuration file + +AUTHOR +4Front Technologies + |
