ABOUT THE LP32
24
Alternately, the LP32 can be connected to the
Ethernet port on a recent-generation Mac (any
Mac with Thunderbolt on it) running Mac OS X El
Capitan (10.11) or later for audio interface
operation through AVB Ethernet.
On-board DSP with mixing and effects
LP32 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/TSN 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. You
may also hear AVB referred to as AV B / T S N or
simply TSN because the IEEE is in the process of
renaming the standard to Time Sensitive
Networking to accommodate the expanding scope
of the specification to applications beyond audio
and video.
The AVB Ethernet network port on the LP32 lets
you add a second AVB-equipped MOTU interface
using any standard CAT-5e Ethernet cable. You can
network up to five MOTU interfaces together using
a MOTU AVB Switch™ (sold separately), and then
run them as a stand-alone network or as an
extended bank of I/Os for your computer-based
production system (or both). You can even connect
multiple computers, each with full access to all
devices on the network (including the other
computers).
With additional standard AVB switches (from
MOTU or other brands) and standard Ethernet
cabling, you can build an extensive AVB audio
network. The entire network operates with near-
zero network latency, even over very long cable
runs. MOTU’s AVB implementation allows you to
stream hundreds of audio channels among devices
and computers on the network with guaranteed
Quality of Service (QoS), prioritizing audio
streams over less important traffic.
Matrix routing and multing
The LP32 provides completely flexible matrix-style
audio routing and multing. You can route any
input, computer channel, or network stream to any
other output, computer, or network device. You
can also mult any single input to unlimited
multiple output destinations.
Web app control
You can control the LP32’s on-board DSP, mixing,
device settings, clock/sync settings and network
audio routing from the MOTU Pro Audio Control
web app software running in your favorite browser
on a laptop, tablet or smart phone. Multiple devices
can be used simultaneously on a shared Wi-Fi
network to access any audio interface settings.
Optional password protection prevents
unauthorized access from the network.
Stand-alone mixing with wireless control
If you connect the LP32 to an Apple Airport or
other Wi-Fi 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.
