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 828es provides completely flexible matrix-
style audio routing and multing. You can route any
analog or digital 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 828es 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 828es 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.
ADAT digital input
The 828es provides two 8-channel banks of optical
digital I/O. Connect outboard digital processors,
digital mixers or other gear: 16 channels at 44.1/48
kHz or 8 channels at 88.2/96 kHz. Alternately, the
optical ports can be independently configured to
support stereo TOSLink (optical S/PDIF).
The
banks operate independently, including input and
output, allowing you to mix and match any optical
formats. For example, you could receive four
channels of 96 kHz S/MUX input on Bank A
while at the same time sending 96 kHz stereo
optical S/PDIF (“TOSLink”) from the Bank A
output.
S/PDIF
The 828es rear panel provides S/PDIF input and
output in two different formats: RCA “coax” and
optical “TOSLink”. The RCA jacks are dedicated to
the S/PDIF format. The TOSLink jacks can be
used for either TOSLink or ADAT optical, as
discussed earlier.
MIDI I/O
The standard MIDI IN and MIDI OUT jacks
supply 16 channels of MIDI I/O to and from the
computer via the Thunderbolt or USB connection.
Timing accuracy can be sample-accurate with host
software that supports it.
On-board SMPTE synchronization
The 828es can resolve directly to SMPTE time
code via the quarter-inch SMPTE input, without a
separate synchronizer. A SMPTE out jack is also
provided for time code distribution. The 828es
provides a DSP-driven phase-lock engine with
sophisticated filtering that provides fast lockup
times and sub-frame accuracy.
Word clock
The 828es supports standard word clock synchro-
nization at any supported sample rate. When the
828es is operating at 96 kHz, it can generate word
clock output at either 96 or 48 kHz. Half-rate
output is supported for all high sample rates (from
88.2 to 192 kHz).
