ABOUT YOUR MOTU AVB AUDIO INTERFACE
28
Other MOTU AVB interfaces
The 1248, 8M and 16A are part of a larger family of
audio interfaces, summarized below, with
complementary I/O configurations.
24Ai
72 simultaneous audio channels
24Ao
72 simultaneous audio channels;
Monitor 8
40 simultaneous audio channels (54 connections)
112D
224 simultaneous audio channels
Universal connectivity
The 1248, 16A, and 8M can connect to a computer
with Thunderbolt or high-speed USB 2.0 (which is
compatible with USB 3.0). They are USB audio
class-compliant, which means that they are iPad
compatible (with a camera connection kit) and do
not require driver installation for USB connection
to a computer. Industry standard audio drivers for
both Thunderbolt and USB operation provide
universal compatibility with any audio software.
Alternately, the 1248, 16A, and 8M can be
connected to the Ethernet port on a recent-
generation Mac (any Mac with Thunderbolt on it)
running Mac OS X Yosemite (10.10) or later for
audio interface operation through AVB Ethernet.
On-board DSP with mixing and effects
Each interface is equipped with a powerful DSP
engine that drives both an extensive routing matrix
and a 48-input digital mixer with 12 stereo busses
and effects. The mixer offers familiar operation
modeled after large format mixing consoles.
32-bit floating point processing
All of the mixing and effects processing in the DSP
engine is handled with 32-bit floating point
calculations, to maintain and deliver virtually
unlimited headroom and the utmost in sound
quality.
Modeled vintage effects processing
Effects include “classic” reverb, compression
modeled after the legendary Teletronix LA-2A
compressor, and 4-band EQ modeled after British
analog console EQs.
AVB system expansion and audio networking
AV B stands for the IEEE 802.1 Audio Video
Bridging Ethernet standard for high-bandwidth,
low-latency audio streaming over Ethernet. The
AVB Ethernet network port on each MOTU
interface lets you add a second AVB-equipped
MOTU interface using any standard CAT-5e
