WARNING: DO NOT PERMIT FINGERS TO TOUCH THE TERMINALS OF PLUGS WHEN INSTALLING OR REMOVING THE PLUG TO OR FROM THE OUTLET. WARNING: IF NOT PROPERLY GROUNDED THE MOTU 896HD COULD CAUSE AN ELECTRICAL SHOCK. The MOTU 896HD is equipped with a three-conductor cord and grounding type plug which has a grounding prong, approved by Underwriters' Laboratories and the Canadian Standards Association. This plug requires a mating three-conductor grounded type outlet as shown in Figure A below. [. . . ] If you hear this sort of thing, check the sample rate settings in your hardware and here in the MOTU FireWire Audio Console. Figure 5-1: The MOTU FireWire Audio Console gives you access to all of the settings in the 896HD hardware. 36 MOTU FIREWIRE AUDIO CONSOLE ■ The headphone output can be assigned to any analog output pair or the Phones setting (as described in “Phones” on page 40). But at the 4x sample rates, the Phones output is not available from the computer. Instead, it is only available as a destination for the two CueMix DSP mixes. In this case, you would set the 896HD clock source setting to ADAT 9-pin, as described below. AES/EBU The AES/EBU clock source setting refers to the AES/EBU input connector on the 896HD. This setting allows the MOTU 896HD to slave to another AES/EBU device. Use this setting whenever you are recording input from a DAT deck or other AES/EBU device into the 896HD. It is not necessary in the opposite direction (when you are transferring from the 896HD to the DAT machine). For further details about this setting, see “Syncing AES/EBU devices” on page 28. Word Clock In The Word Clock In setting refers to the Word Clock In BNC connector on the 896HD rear panel. Choosing this setting allows the 896HD to slave to an external word clock source, such as the word clock output from a digital mixer. ADAT 9-pin The ADAT 9-pin clock source setting refers to the ADAT digital audio synchronization format. It allows the 896HD to slave to an ADAT — or ADAT sync chain — via its ADAT sync 9-pin connector. ADAT sync also carries precise, sample location information, which allows Cubase or other sampleaccurate ASIO 2. 0-compatible audio software to transfer audio to and from ADAT-sync compatible recorders without drifting by as much as one sample. Use this setting when you are using the 896HD with one or more ADAT-sync compatible recorders. Make sure the 896HD is connected to the end of the ADAT sync chain. The main outs mirror the phones. Clock Source The Clock Source determines the digital audio clock that the 896HD will use as its time base. For a complete explanation of synchronization issues, see “Making sync connections” on page 21. Internal Use the Internal setting when you want the 896HD to operate under its own digital audio clock. For example, you may be in a situation where all you are doing is playing tracks off hard disk in your digital audio software on the computer. In a situation like this, you most often don’t need to reference an external clock of any kind. You can operate the 896HD system on its internal clock, and then slave the DAT deck to the 896HD via the AES/EBU connection (usually DAT decks slave to their AES/EBU input when you choose the AES/EBU input as their record source) or via the 896HD’s word clock output (if your DAT deck has a word clock input). If you would like help determining if this is the proper clock setting for your situation, see “Do you need a synchronizer?” on page 22. [. . . ] As soon as the computer boots up, Windows will try and initialize the WDM Driver. To determine if the WDM Driver is the problem, boot up in Safe Mode or remove the MOTU Audio software with the Add/Remove Programs Control Panel then restart. Reinstall the 896HD software and choose only to install the MOTU FireWire ASIO driver, not the WDM Driver. ‘New hardware detected’ window If you connect your 896HD before running the 896HD Software Installer CD, Windows will prompt you that new hardware has been detected.
