pad can be supplied independently to each mic
input. The Precision Digital Trim™ knobs on the
front panel for each mic/instrument input provide
up to 63 dB of boost in precise 1 dB increments.
As explained in “Mic/guitar sends” on page 24, the
pre-amplified signal can be routed to external
outboard gear before being routed back into the
828es.
Mic/guitar sends
Before A/D conversion, the pre-amplified signal
from each front-panel mic/guitar input is routed
to one of the two rear-panel quarter-inch analog
sends, so that you can insert a favorite outboard
EQ, compressor, amp or effects processor to the
mic/guitar input signal before it is converted to
digital form. The resulting output from the
outboard gear can be fed back into the 828es via
one of the eight TRS analog inputs on the rear
panel, for routing to the computer and/or
inclusion in the 828es built-in monitor mixes.
Flexible analog I/O with Precision Digital Trim™
All quarter-inch analog inputs can accept either a
balanced or unbalanced plug. The quarter-inch
outputs are DC-coupled, so they can be used for
CV control output.
Analog inputs are equipped with digitally
controlled analog trims, adjustable in 1 dB
increments. Equipped with renowned ESS
Sabre32™ DAC technology, all 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.
Independent XLR main outs
The XLR main outs are equipped with very high
quality ESS Sabre32 D/A converters and serve as
independent outputs for the computer or the
828es on-board mixer.
On-board DSP with mixing and effects
828es is equipped with a powerful DSP engine that
drives both an extensive routing matrix and a
48-input digital mixer with 12 stereo buses 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
AVB 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
AVB/TSN 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 828es 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).
