ABOUT YOUR MOTU AVB AUDIO INTERFACE
25
channel, or network stream to any other output,
computer, or network device. You can also mult any
single input to unlimited multiple output
destinations.
24 channels of network audio I/O for your host
computer
The 24Ai and 24Ao let you stream up to 24 audio
channels in and out, simultaneously, through their
USB connection to a host computer. Sources and
destinations can include inputs and outputs on the
device, inputs and outputs on other interfaces on
the network, and even audio software apps
running on other computers connected to other
devices on the network.
Web app control
You can control on-board DSP, mixing, device
settings, clock/sync settings, and network audio
routing from the MOTU AVB Control web app
software running in your favorite browser on a
laptop, tablet or smart phone connected to your
MOTU interface directly, or through your local
WiFi network. Multiple devices can be used simul-
taneously to access any audio interface settings on
the network.
Stand-alone mixing with wireless control
If you connect your MOTU interface to an Apple
Airport or other WiFi router with a standard
Ethernet cable, you can control its powerful mixing
and DSP effects from your smart phone or tablet,
without a computer — great for live sound mixing
from your iPad, tablet, or other wireless device.
ADAT digital I/O
The 24Ai and 24Ao interfaces each provide three
8-channel banks of optical digital I/O. Connect
outboard digital processors, digital mixers or other
gear: 24 channels at 44.1/48 kHz or 12 channels at
88.2/96 kHz.
Word clock
Each MOTU interface supports standard word
clock synchronization at any supported sample
rate. When the interface is operating at 96 kHz, it
can generate word clock output at either 96 or
48 kHz; the 1x equivalence is available as an option
for word clock output when running at high
sample rates (from 88.2 to 192 kHz). The word
clock OUT port can alternately be used as a THRU
port for word clock daisy-chaining. To configure,
use the LCD menu to navigate to Settings -> Word
Clock Thru Mode.
Comprehensive metering
The large backlit LCD displays all signal activity at
a glance with detailed metering for all analog and
digital I/O. You can access many hardware settings
directly from the front panel.
Precision Digital Trim™
Analog inputs are equipped with digitally
controlled analog trims, adjustable in 1 dB
increments. Analog outputs offer 32 bit trim in the
DAC, also adjustable in 1 dB increments. You can
save your trim configurations as a preset for instant
recall.
Rack mount or desktop operation
Each interface is housed in a sturdy, metal-alloy,
19-inch, rack-mountable unit. The rack mounting
brackets can be removed using a 7/64” hex wrench
for desktop operation.
