Audio Outputs
The 970 features a total of 82 unique output channels. Any of the internal 64 tracks can be routed to
each of the 8 analog outputs, 8 AES3 outputs, and 64 MADI outputs. Internal tracks 1 through 64 are
permanently routed to Dante outputs 1 through 64 respectively.
Analog Audio Outputs
The eight analog outputs of the 970 are active-balanced, line-level outputs (+18dBu max). Analog
Line Output channels 1 and 2 are available on XLR connectors on the rear panel. Analog Line Output
channels 1 to 8 are available on a DB25 connector on the rear panel. At factory default, the source of
the Analog Line Outputs 1-8 is tracks 1 to 8, respectively. Any of the available 64 Tracks can be sent
to the Line Outputs. Line Output routing is set in
[Audio - Line Output]
.
Digital Audio Outputs

Output channels 1 to 8 . At factory default, the source of the AES Outputs 1-8 is tracks 1 to 8, respec-
tively. Any of the available 64 Tracks can be sent to the AES Outputs. AES Output routing is set in
[Audio - AES Output]
.
Dante Audio Outputs
Tracks 1-64 are permanently routed to Dante Outputs 1-64 respectively. Up to four 970 units can be
daisy-chained using their built-in internal Ethernet switches. If using five or more 970 units, Sound
Devices recommends using an external Ethernet Switch in a star configuration.
MADI Audio Output
Both the SC Optical and BNC MADI outputs provide 64 channels of digital audio. At factory default,
the source of the MADI Audio Outputs 1-64 is tracks 1 to 64, respectively. Any of the available 64
Tracks can be sent to the MADI Output. MADI Output routing is set in:

Headphone Output
The 970 is capable of driving headphones to extremely high sound pressure levels. Hearing experts advise
against exposure to high sound pressure levels for extended periods.
The 970’s headphone output is a flexible tool for monitoring audio. The headphone level is adjusted
using the Headphone Volume Knob. To quickly select a headphone source, press and hold the AU-
DIO Button while turning the Control Knob. The Headphone Source can also be selected in the Setup
Menu option
[Audio - HP Source]
.
Any input can be soloed in the Main View: Rotate the Control Knob to highlight the input, then press
AUDIO + LCD. The input’s signal will be soloed in the headphone monitors and the input that is
soloed will be indicated on the top-right of the Main View (
HP: Solo8
for example). Highlight the
soloed track, then press AUDIO + LCD again to un-solo the input and return to previous Headphone
Source.
Warning Bells are sent to the headphone monitor to alert the user of various states such as transport
changes, selected sync reference absent, and errors such as No Media Connected. The loudness of
these warning bells is adjustable from Off, -60 to -12 dBFS in
[System - HP Warning Bell Level]
. At
factory default, the warning bells are set to -40 dBFS.
