STAND-ALONE MIXER
Choose the Stand-alone mixer preset to use the
LP32 as a mixer. Doing so routes all physical inputs
to the mixer, with the mixer’s main mix bus going
to Headphone Out L-R. If needed, you can use the
routing grid to also send the main mix to any
optical output pair on any bank, or even multiple
output pairs.
The Monitor bus is set up as a solo bus.
To control the mixer (with the web app), you have
several options. You can connect a computer to the
LP32 using USB, Ethernet, or Wi-Fi, as explained
in “Setup for web app control” on page 37.
Figure 5-2 below shows the Wi-Fi scenario. Note
that you can control the mix from multiple Wi-Fi
devices.
Figure 5-2: Using the LP32 as a stand-alone mixer. This example
demonstrates how you can control the mixer from several Wi-Fi
devices.
INTERFACE + MIXER
Choose the Interface + Mixer preset to use the LP32
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 LP32’s on-board
mixer, which mixes them to the Headphone Out
L-R. The on-board mixer mixes all of the following
sources:
■ All LP32’s optical inputs (from all four banks)
■ From Computer channels 1-16 (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.
