Introduction
The AVN-HA1 and AVN-HD1 are headphone amplifiers which can be combined with AVN-Portal units to provide a headphone distribution system. The units can be powered via their connection to an AVN-Portal or alternatively via a DC power connector located on the rear panel of the unit. On the front panel a 6.35 mm (1/4”) headphone socket is available along with a volume control knob. A ‘Mute’ button is also provided that controls a GPO which can trigger an AVN- Portal to perform functions such as muting an input stream or an output stream. A power status indicator LED is located on the front panel of the device. This will illuminate red when power is available. On both units, a loop through audio output is available. This allows the headphone amplifiers to be daisy chained, or to be quickly and easily inserted in-line between two other pieces of equipment, allowing monitoring of the audio feed. The AVN-HA1 is compatible with the AVN-PA8/D and the AVN-PM8/D Portals. The AVN-HD1 is compatible with the AVN-PD8/D Portal.
Application Example
Front Panel
Power Status LED
The power status LED illuminates red when a power source is available. Power
can be supplied via the input ethernet connection located on the rear panel of
the unit by connecting the unit to an AVN-Portal or by the 12V DC (Max 2W)
connection on the rear panel of the unit.
Mute/GPO Button
The mute/GPO button is a push switch that controls a general-purpose output
which is connected to an AVN-Portal via the portal RJ45 connection on the rear
panel of the unit. The mute/GPO button can be set as a momentary or latching
switch by inserting/removing an internal pin (set as momentary by default.
Contact Sonifex for more information). The action can then be set up via the
AVN-Portals web server in order to provide functionality such as
muting/unmuting I/O, controlling LEDs, and controlling relays. See the
relevant AVN Portal handbook for more information.
Headphone Socket
The 6.35 mm (1/4”) headphone socket can be used to connect headphones to the
unit. The high-quality output can be used to drive 150 mW of power into
headphones with an impedance from 32Ω to 600Ω. The headphone socket has the
following pinout;
- Tip : Headphone Left
- Ring : Headphone Right
- Sleeve : Ground
Volume Control Knob
The volume control knob can be used to control the level of audio supplied to
the user headphones from -60dB to +6dB.
Rear Panel

- Pin 8 : No connection
The audio connections are compatible with any other analogue products using the StudioHub+ TM pinout.
12V DC Input Max 2W
It can either be used as a second power supply (for redundancy) or used to
power the AVN-HA1 if not being used in conjunction with an AVN-PA8 IO.
AVN-HD1
Stereo Digital Input
The stereo digital input provides connections for stereo digital audio, power,
and the general-purpose output. It is an RJ45 port with the following pinout;
- Pin 1 : Input AES + (Phase)
- Pin 2 : Input AES – (Non-phase)
- Pin 3 : No connection
- Pin 4 : Ground
- Pin 5 : Cough/Mute (Active low)
- Pin 6 : No connection
- Pin 7 : No connection
- Pin 8 : +12V
Stereo Digital Output
The stereo digital output is used to pass on the stereo audio being routed to
the unit. It is an RJ45 port with the following pinout;
- Pin 1 : Output AES + (Phase)
- Pin 2 : Output – (Non-phase)
- Pin 3 : No connection
- Pin 4 : Ground
- Pin 5 : No connection
- Pin 6 : No connection
- Pin 7 : No connection
- Pin 8 : No connection
The audio connections are compatible with any other digital products using the StudioHub+TM pinout.
12V DC Input Max 2W
The 12V DC Input (Max 2W) connection is located on the rear panel of the unit.
It can either be used as a second power supply (for redundancy) or used to
power the AVN-HD1 if not being used in conjunction with an AVN-PD8 IO.
