HARDWARE INSTALLATION

this case, audio cannot be streamed between

MOTU AVB devices that don’t share the same

master clock.

Resolving the master clock device to an

external clock source

The MOTU device you’ve speciﬁed as the AVB

network clock master can itself be resolved to an

external time base such as word clock (if available)

or ADAT optical. Just choose the desired clock

source from its Clock Mode menu (in the Device

tab). Doing so effectively resolves the entire AVB

network to the external clock source.

SYNCING MULTIPLE AVB AUDIO

INTERFACES CONNECTED TO A MAC

There are several options for clocking multiple

AVB audio devices connected to the Mac:

■ You can resolve them to an external clock source

(like word clock, if available).

■ You can choose Mac: System Clock as the clock

source for each device (in the Audio MIDI Setup

clock source menu).

■ You can create an aggregate device, as usual. The

aggregate device setup panel has a check box called

Drift Correction, which sample-rate converts

devices that are not synchronized.
