16A Rear Panel
1. The 16A is equipped with an auto-switching interna-
tional power supply.
2. BNC word clock jacks. Use them for a variety of applica-
tions, such as digital transfers with devices that cannot
slave to the clock supplied by their digital I/O connection
with the 16A.
3. These ADAT optical “lightpipe” jacks provide 16 channels
of 24-bit ADAT optical digital I/O at 1x sample rates (44.1
or 48 kHz) and 8 channels at 2x sample rates (88.2 or 96
kHz). They are disabled at higher sample rates. The IN
and OUT ports on the right provide channels 1-8 (or 1-4),
and the left-hand ports provide channels 9-16 (or 5-8).
4. The 16As sixteen analog outputs are balanced TRS
quarter-inch connectors that can also accept an unbal-
anced plug (with the ring disconnected). The output trim
can be adjusted from the Output Setting section of the
Device Tab in the MOTU AVB Control web app software.
5. These sixteen analog inputs are balanced TRS quarter-
inch connectors that can also accept an unbalanced plug.
Use with line level signals up to +24 dBu, including
synthesizers, drum machines, effects processors, etc.
These inputs are also equipped with the 16As Precision
Digital Trim™ feature: digitally controlled analog trims
that let you adjust input level in 1 dB increments from
the included MOTU AVB Control web app software.
6. Connect the 16A to the computer here via either
Thunderbolt or USB 2.0, using a standard Thunderbolt or
USB cable. For details, see “Setup for multiple Thunder-
bolt and USB interfaces” on page 39.
7. The AVB Ethernet port provides industry standard IEEE
802.1 network connectivity to other network devices.
Examples include:
Another 16A or any other MOTU AVB-equipped device,
such as the 1248 or 8M audio interfaces.
A standard Ethernet hub or WiFi router (for internet
connection and communication with the MOTU AVB
Control web app software).
A standard AVB Ethernet switch for high-speed, low-
latency, high-capacity audio connectivity to an AVB
audio network.
