Using an External Mic
In some applications, it may be benecial to use an external microphone as the input source for
transmitting audio over the Intercom. For example, this might include a head-worn or lavalier mic
used by a musical director, a wireless mic that is being shared by multiple performers, or an o-stage
mic being used by a member of the tech sta for communication purposes.
Using an external microphone to transmit Intercom audio requires that the mic be connected to the
Aviom network and assigned to one of its 64 available audio Slots. In most cases this microphone—
intended to be heard by only the performers using A640 Personal Mixers—would not be routed to
any front-of-house (FOH) mix that the audience would hear. The mic can be connected directly to an
AN-16/i Input Module (with the use of an optional mic preamp), to a line-level input on an AN-16/i
from an analog output on a mixing console, to one of the 16 Slots available on a digital console card,
or from a Dante network.
When using a D800-Dante A-Net Distributor, note that the Audio Source setting for transmitting
audio while using an external microphone must be set to a Dante channel that is both active in the
Dante network and available at the current Dante sample rate.
To choose an external microphone as the Intercom’s transmit audio source:
• Connect the external mic to the audio system's mixing console as you would any other
microphone.
• Route the external mic's audio to an available A-Net network Slot.
• On the A640, press the MixeR Setup button.
• Choose Intercom from the menu.
• Press the encoder button to open the Intercom options.
• Select the Audio Source option by pressing either encoder button.
• Scroll to select the network Slot where the external mic is connected.
• Press either encoder button to conrm the selection.
