The AVN-HA1 headphone amplifiers can be combined with the Sonifex AVN-PA8/D and AVN-PM8/D to provide 8 separate headphone signals. Each of which can receive a distinct feed mixed from any physical or stream input. It can be used independently of the portals by using the separate DC input for power and a separate analogue input. The unit can be mounted using the CM-MNT1 desk mount panel.
Product Features
Front panel 6.35mm (1/4”) headphone socket and volume control knob, with mute/GPO push button.
Locking DC power connector if a portal is not being used to supply the unit with power.
Analogue audio input on RJ45 (the connector provides power to the unit and a GPO back to the portal).
Loop through audio output on RJ45 (power and GPO signal are not connected).
Typical Applications
Headphone distribution system where individual mixes can be created in the AVN portal and sent to up to 8 x AVN-HA1 units, each with individual volume controls. Ideal for a radio or talk studio, a voice-over booth, or a news studio in radio or TV.
