12. Operation and Usage

12.1 Playback

The Fireface 800 can play back audio data in supported formats only (sample rate, bit resolu- tion). Otherwise an error message appears (for example at 22 kHz and 8 bit).

In the audio application being used, Fireface must be selected as output device. This can often be found in the Options, Preferences or Settings menus under Playback Device, Audio Devices, Audio etc.

We strongly recommend switching all system sounds off (via >Control Panel /Sounds<). Also Fireface should not be the Preferred Device for playback, as this could cause loss of synchroni- zation and unwanted noises. If you feel you cannot do without system sounds, you should con- sider buying a cheap Blaster clone and select this as Preferred Device in >Control Panel /Multimedia /Audio<.

The screenshot shows a typical configuration dia- log of a (stereo) wave editor. After selecting a device, audio data is sent to an analog or digital (ADAT / SPDIF) port, depending on which has been selected as play- back device.

Increasing the number and/or size of audio buff- ers may prevent the au- dio signal from breaking up, but also increases latency i.e. output is de- layed. For synchronized playback of audio and MIDI (or similar), be sure

to activate the checkbox ‘Get position from audio driver’.

The Fireface’s ADAT optical interfaces support sample rates of up to 96 kHz using a standard ADAT recorder. Single-channel data at this frequency requires two ADAT channels, achieved using the Sample Multiplexing technique. This reduces the number of available ADAT channels from 8 to 4. Under Windows MME, channels are routed to ADAT devices in double-speed mode as follows:

Only the four stereo pairs of the device ADAT1 are available

The channels of the device ADAT2 are no longer available

This kind of implementation allows a problem-free usage of both ADAT ports in Single and Dou- ble Speed, as the routing for ADAT1 doesn't change. However, the hardware spreads the data differently:

Channel 1 is transmitted via channels 1 and 2, channel 2 via 3 and 4 etc.

The ADAT2 port transmits channels 5 to 8

Please refer to the diagram in chapter 18.2. Routing for record and playback is identical.
