Sonifex AVN-DIO12 Dual Mono Microphone Input to Dante with Gain

Sonifex AVN-DIO12 Dual Mono Microphone Input to Dante with Gain

The Sonifex DIO line of Dante® input/output devices includes the AVN-DIO12, a twin microphone input to Dante® converter with configurable mic gain. Essentially, it is a single chassis housing two AVN-DIO09 units, providing A/D circuitry with a superior E.I.N. of 129dB. It has one Neutrik etherCON connector for direct connection to a Dante® AoIP network and two balanced analog XLR inputs. Each microphone may be routed via Dante Controller to any Dante receiver and features a tri-color level LED, phantom power, high pass filter, and coarse and fine gain settings. It’s powered using Power over Ethernet (PoE), using a Neutrik etherCON connector for power and data redundancy. The AVN-DIO12 uses the latest Audinate Dante chipset so is AES67 and Dante Domain Manager compliant.

Gain Adjustment

The AVN-DIO012 has coarse and fine mic gain for each microphone input. The coarse gain is set using the toggle switch, which provides 20dB/50dB of gain. The fine gain can be set using a trimmer adjustment tool, or a small flat-blade screwdriver, and adds between 0dB and 36dB of additional gain.

High Pass Filter

Each microphone input has an on/off toggle switch which turns the high pass filter on or off. When enabled, it acts on frequencies below 125Hz at a roll-off of 6dB/octave.

Phantom Power

Phantom power is enabled/disabled via a toggle switch on the front panel for each microphone input. When enabled, a 48V DC supply is provided to power an appropriate microphone. The red LED next to each input will illuminate to indicate phantom power is enabled.

Audio Level LED

To help you set the mic gain, a level LED is provided on the front panel for each microphone input to display the audio level being sent to the Dante network.  The indicator thresholds are as follows:

• Off: Level is under -38dBFS (-20dBu)
• Green: Level is between -38dBFS (-20dBu) and -18dBFS (0dBu)
• Amber: Level is between -18dBFS (0dBu) and -10dBFS (+8dBu)
• Red: Level is above -10dBFS (+8dBu)

Note: When using a phantom powered microphone, it may be necessary to earth the unit using the rear panel earth tag to eliminate the mains hum.
