28 inputs and 30 outputs
All 828mk3 inputs and outputs can be used simul-
taneously, for a total of 28 inputs and 30 outputs
when operating at 44.1 or 48 kHz:
Connection
Analog 24-bit 192 kHz on bal/unbal TRS
Mic/guitar 24-bit 192 kHz on XLR/TRS combo
Main outputs 24-bit 192 kHz on XLR
Headphone output*
ADAT optical digital†
RCA S/PDIF 24-bit 96kHz digital
Total
* The phone jack below the MASTER VOL knob is
hard-wired to (mirrors) the XLR main outs. The
PHONES output can operate as an independent
output pair, or it can mirror any other 828mk3
output pair, such as the main outs.
† The 828mk3 optical connectors support several
standard optical I/O formats, which provide
varying channel counts. See "Optical" on page 11
for details about optical bank operation.
With the exception of the phone jack on the front
panel labeled "(MAIN)", all inputs and outputs are
discrete. For example, using a mic input does not
"steal" an input from the TRS analog I/O bank.
Analog
All analog inputs are equipped with 24-bit 192 kHz
A/D converters. All analog outputs have 24-bit
192 kHz D/A converters. All audio is transferred to
and from the computer in a 24-bit data stream.
All quarter-inch analog inputs can accept either a
balanced or unbalanced plug.
