1. This is the Output tab, which
provides settings for the 828's
analog and digital outputs.
2. These monitor controls (main
volume, MUTE and SOLO) are the
same as the controls on the front
panel of the 828 and in the Home
tab (item #8 on page 42).
3. The determines
Monitor Group
which outputs are controlled by the
Main Out volume knob on the 828's
front panel (item #9 on page 11),
plus the Main Volume controls in the
Home tab (item #8 on page 42) and
here in the Output tab. For example,
if your studio has a pair of main
monitors, plus a sub-woofer
connected to Line Out 3, you could
click the Line Out 3 button to add it
to the main volume controls. If you
have 5.1 or 7.1 surround monitoring,
you can add the surround channels
to the monitor group to be able to

control the volume of all surround
outputs simultaneously with the
Main Volume knob. Please note: the
Main Out 1-2 pair is always part of
the Main Volume Group.
4. A/B Monitoring lets you connect two
sets of speakers and then check your
mixes on each pair by toggling
between your A speakers and B
speakers. These are the same
controls as on the front panel. See
"A/B Mode" on page 38.
5. Meters and volume controls for the
two Headphone outputs. These are
the same as the PHONES 1 and 2
volume control on the front
panel.You can also choose among
many possible sources for each
headphone output.
6. All analog outs can be trimmed (in
the DAC) from zero to -∞ dB. This
can be useful for speaker calibration

or other situations where you need a
fixed amount of level adjustment for
a particular output (or output pair).
7. By default the Source for the RCA
S/PDIF output is set to USB channels
from your host audio software, as
shown in the menu. Alternately, you
can send any 828 monitor mix to the
RCA S/PDIF output.
8. The Source menus let you choose the
source for each Optical Output bank.
By default, the source is set to USB
channels from your host audio
software, as shown above in the
menus. However, if you would like to
use the 828 as an ADAT optical
expander, the menus provide a
number of options for routing
analog input channels to the optical
outputs. Doing so patches the line
inputs directly to the outputs.

Optical Input banks, for conve-
nience.
10. When the Optical Out format is
TOSLink (TOS), the Bank A Source
menu lets you send any 828 monitor
mix (or any analog input pair) to the
optical output.
11. Configure the Bank A format for
either 8-channel ADAT or stereo
TOSLink. At 88.2 or 96 kHz, the ADAT
setting supports 4-channel SMUX
format. Note that you can choose a
different format for the IN and OUT.
See "Optical I/O" on page 27.
12. Choose the Loopback Source here.
This is the signal that will be
returned to the computer on the
Loopback channels. See "Loopback"
on page 61.
