The Multiple Element Interface System in Use

When a Multiple Element Interface System is first powered up, one of the two interfaces is designated at random to be the

Master interface. The Master’s front panel LED light will be green while the Slave’s front panel LED light will be blue (if the

Slave interface LED is flashing red, check that optical cables are connected as shown above).

Note that only the Master interface has these attributes:

● System clock master

● Main outputs configurable for connection to speakers

● Inputs listed first in DAW input lists.

To change the Master device, open the System sidebar, then change the designated interface in the Master Device dropdown.

Inputs and outputs of the two Element interfaces are aggregated in the Apogee Thunderbolt driver, so that both interfaces

appear as one audio device named Apogee Thunderbolt in your DAW or in OS X System Sound Preferences. To distinguish

inputs for each interface, Master input labels include the prefix A, Slave input labels include the prefix B.

Likewise, Element Control Input settings, Low Latency mixer channels, and Main/Headphone output controls are labelled with

A and B prefixes to distinguish Master and Slave software controls.

Once two Element interfaces have been connected, Element Control retains data from both, even if one of the interfaces is

later disconnected. This means that even if one interface is missing, the I/O detected by your DAW and OS X remains

consistent, plus all previously saved Snapshots remain compatible.

Disconnected interfaces appear as “offline” devices; all settings in Element Control pertaining to an offline device appear in a

greyed out state.

To permanently delete an offline device, open the Device sidebar and click on the Trashcan icon at the

bottom of the offline device’s settings.
