PRESETS

STAND-ALONE MIXER
Choose the Stand-alone mixer preset to use 624 as
a mixer. Doing so routes all physical inputs to the
mixer, with the mixer’s main mix bus and monitor
bus going to the Main Outs and Phones,
respectively.
To control the mixer (with the web app), you have
several options. You can connect a computer to the
624 using Thunderbolt, USB, Ethernet, or Wi-Fi, as
explained in “Setup for web app control” on
page 38. Figure 5-2 below shows the Wi-Fi
scenario. Note that you can control the mix from
multiple Wi-Fi devices.

demonstrates how you can control the mixer from several Wi-Fi
devices.
INTERFACE + MIXER
Choose the Interface + Mixer preset to use the 624
as both an audio interface and mixer, simulta-
neously. This preset is identical to the Audio
Interface preset, except that all From Computer
channels are also routed to the 624’s on-board
mixer, which mixes them to the Main Mix bus (to
the Main Outs) and the Monitor bus (to the
Headphone Out). The on-board mixer mixes all of
the following sources:
■ The 624’s analog inputs
■ The 624’s optical inputs
■ All From Computer channels (Thunderbolt or
USB channels from the host computer)
The Monitor bus is set up as a solo bus.
In this scenario, you can control the mixer from the
MOTU Pro Audio Control web app running on the
computer. You can also run the web app from
wireless devices on the same Wi-Fi network as the
laptop.
