AVN-Portals 1
The portals can be combined with the Sonifex AVN-HA1 and
AVN-HD1 headphone amplifiers to provide 8 separate headphone
signals where each headphone amplifier can be sent a separate
feed, mixed from any physical or stream inputs. On portal units
with RJ45 outputs, an AVN-HA1 (for the AVN-PA8 and AVN-PM8)
or AVN-HD1 (for the AVN-PD8) headphone amplifier can be used
to listen to the outputs, with the portals providing power and audio
signals. The switches on the front panel of the AVN-HA1 and AVN-
HD1 can be used as another GPI for muting the output (in the GPIO
settings menu these are known as ‘Cough Ports’). Please refer to the
Sonifex website for more information on the AVN-HA1 and AVN-HD1
headphone amplifiers.
