Up to eight Lynx cards can be installed in a single PC and utilized by a single application. If more than one card is being installed initially, simply install the driver per standard instructions, and each card will be correctly set up and recognized by the operating system. If additional cards are being added to an existing installation using our Version 1/NT4 driver package, you will need to run the driver setup again after installing the new cards. If expanding an installation using the Version 2/WDM driver package, the driver will update automatically.

It is crucial to establish a Master/Slave clock relationship so that all cards are operating off of the same sample clock. Either an external clock source should be used that provides sample clock to all of the cards via their word-clock or digital in connections, or our CBL-ICC Internal Clock Cable should be used to synchronize the card’s sample clocks. If an external clock source is used, the clock source for each card should be set to the appropriate source (either “Digital” or “External”) from the Lynx Mixer Adapter page – there will be one Adapter page per card.

If our CBL-ICC cable is used to synchronize the cards internally, one card acts as the master to supply a clock signal to the other slave cards in the system. Typically, the leftmost or rightmost card is selected as the master in order to simplify cable connections. Starting with the master card, connect the cable from its “Clock Out” header connector to the “Clock In” connector on the next card. Continue the clock “daisy chain” by connecting the “Clock Out” to “Clock In” for the remainder of the cards. From the Lynx Mixer, set the sample clock source on the Adapter page for the master card to the appropriate clock source (“Internal”, “Digital”, etc.). For the slaves, set the sample clock source to “Header”.

Within your recording application, each Lynx card will be identified by a unique adapter ID number (i.e. AES16 1, AES16 2, etc.) so you can choose record and play channels appropriately. Please refer to the “Configuring Multiple Lynx Cards” section of your user manual for more information.

Lynx cards do not have multi-card capability with OS9.

Up to four Lynx cards can be installed in a single Macintosh running OSX. Running the driver once will provide support for all cards installed. If a card(s) is added to an existing installation, a Lynx Mixer will be created for that card on first boot (remember that the new cards must be programmed with the Mac firmware before they will be usable). Under OSX 10.2 and 10.3, multiple cards cannot be utilized by a single Core Audio application at one time, except for Digital Performer 4. Starting with OSX 10.4 Aggregate Device Support allows multiple cards to be used by any multi-track Core Audio application.

To create an aggregate device, open Applications > Utilities > Audio/MIDI setup. Click Audio > Open Aggregate Device Editor. Check "Use" next to the cards that you want to use for the aggregate device. You can create a custom name, or just use the default name (Aggregate Device).

Select this aggregate device in your recording software and you can use all the available channels from the cards used.

With a multi-card configuration, it is crucial to establish a Master/Slave clock relationship so that all cards are operating off of the same sample clock. Either an external clock source should be used that provides sample clock to all of the cards via their word-clock or digital in connections, or our CBL-ICC Internal Clock Cable should be used to synchronize the card’s sample clocks.
