Section 13.2 Headphones
At the extreme left side of the
Audio Mixer
you will observe a simple volume control
for the
Headphones
output. By default, headphones connected to this stereo output
jack will carry the first two channels of the audio signal from the bus designated
Master –
that is, the same audio carried by analog outputs marked
1
and
2
in the
AUDIO OUT
group on the unit’s backplane.
Remember that the Headphone output is also affected by Solo switches located at
the bottom of each control group in the Audio Mixer . When Solo is enabled for one or more sources, only
the soloed sources are sent to the connector. (See Solo in Section 13.7.2 for more information on this
feature.)
Section 13.3 VU Meters
VU
(Volume Unit)
meters
are located right above the
Volume
control sliders throughout the
Mixer
. The
calibration of the
VU meters
can be changed to suit your preference. Click the label below the
Headphone
control at left to open a small menu offering three options as follows:
• dBVU :
most familiar to users of typical analog audio mixers
• dBFS
: dB ‘Full Scale’ – the digital standard; see notes under the heading Audio
Headroom in Section 6.9
• dBU
: based on a voltage of 0.775 VRMS (a shy scale rarely seen in public, supplied
for completeness, comparison, and the amusement of audiophiles)
Section 13.4 External Sources
Columns in the first set of control groups are numbered as
Input 1-8.
Each of these can be assigned to
any audio source available – whether analog (line level) sound supplied to rear panel connectors, SDI or
HDMI embedded audio from one of the backplane video inputs, or any available network audio source.

To access the Connection menu, move the cursor into the label of an input, and click the Configure (gear)
button that appears just at right. The Advanced Audio Configuration panel (Figure 77) will be shown. The
drop-down
Connection
menu at the top of this pane allows the selection of one of the supported sources:
• By default, local physical sources are listed as Input 1 , 2 , and so on
• Follow Video Source – the default selection, follows the same numbered Switcher video input
• All available NDI (network) audio sources
