nothing is plugged in to the front panel input jack,
the return jack can serve as an additional line
input, identical to the other eight analog inputs.
Flexible analog I/O with Precision Digital Trim™
All quarter-inch analog inputs can accept either a
balanced or unbalanced plug. The eight line inputs
are equipped with digital gain, adjustable in 1 dB
increments.
Equipped with renowned ESS Sabre32™ DAC
technology, all analog outputs offer trim (cut), also
adjustable in 1 dB increments.
All quarter-inch outputs are DC-coupled, so they
can be used for control voltage (CV) output.
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 828
on-board mixer.
On-board DSP with mixing and processing
The 828 is equipped with a DSP engine that drives
a 44 x 16 monitor mixer, which supplies each
analog output pair with a unique monitor mix.
Each mix can include any chosen inputs, plus
computer output and the separate reverb bus.
Effects include 4-band parametric EQ,
compression and reverb. The included CueMix 5
app provides easy and intuitive on-screen control
of everything from your computer or iOS device.
32-bit processing
The DSP engine delivers 32-bit floating point
processing for virtually infinite headroom, with
64-bit double-precision processing for the EQ
filters for the utmost in sound quality.
Software control
Control the 828 on-board mixing and device
settings from the CueMix 5 app software running
on a laptop or iOS device.

Stand-alone mixing
Connect an iOS device to the 828 for complete
control of all settings on the road at rehearsals or
gigs — great for live sound mixing.
ADAT digital I/O
The 828 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 Bank A ports can be independently
configured to support stereo TOSLink (optical
S/PDIF).
Bank A input and output operate independently,
allowing you to mix and match optical formats.
For example, you could receive four channels of
96 kHz S/MUX input while at the same time
sending 96 kHz stereo optical S/PDIF
("TOSLink") to the output.
S/PDIF
The 828 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 optical jacks can be used
for either TOSLink or ADAT optical, as discussed
earlier.
MIDI I/O
The 828's standard MIDI IN and MIDI OUT jacks
supply 16 channels of MIDI I/O to and from the
computer through its USB connection. The MIDI
OUT port can be configured as a MIDI THRU
port, if desired.
Word clock
The 828 supports standard word clock synchroni-
zation at any supported sample rate.
Foot switch input
The quarter-inch foot switch input accepts a
standard foot switch. When you push the foot
switch, the 828 triggers a programmable keystroke
on the computer keyboard. For example, with
