• These instructions assume a Sony EVI-D70 camera has been permanently installed in the chapel, with
the control cable run between the camera and the AVDH-1. Other camera scenarios will be described
below.
• One nice feature of the AVDH-1 setup is that audio and video streams are distributed back throughout
the building. This means that the camera feed and audio coming from the chapel can be sent to the
Relief Society, Primary, or other rooms with the proper wiring for overflow purposes. Simply connect a
TV or projector to the video distribution jacks in those rooms, and set the audio switch to Chapel
instead of Local.
• Source Selection: Rotate the selector knob to the Camera (Encoding) position.
• TV/Monitor: Tune the rack TV/monitor to the primary language channel (typically channel 3) to see
the camera feed and hear chapel audio. *Note: in most equipment racks, small TVs or monitors are
already installed and will have already been connected when the AVDH-1 was installed. If your rack
does not have a TV/monitor, connect a monitor to the Video Out port under Outputs. This enables the
operator to see the camera view.
• Headphones: To listen to the audio feed privately, connect headphones to the Audio Out port under
Outputs and turn down the volume on the rack TV/monitor. Adjust volume with the knob just next to
the headphone port as necessary. *Note: again, in the case where small TVs or monitors are already
installed, they will generally also have audio routed to them, so headphones may not be necessary.
• Audio & video feeds into Communicator: The audio and video feeds that come from the
meetinghouse have already been connected into the appropriate ports on the Communicator, along
with the network connection, and should remain permanently connected. The operator only needs to
execute commands on the Communicator’s front panel to start and stop the webcast – no wiring
connections need to be made into the Communicator.
• Camera control: Using a standard A-B USB cable (supplied in the cables & accessories bag that comes
with the AVDH-1), connect from a USB port on a laptop to the Camera Control port on the AVDH-1.
• Software for camera control: Several free software packages are available that allow for remote
camera control of the Sony EVI-D70 (the recommended camera for webcasting). One good choice,
called D70 Commander (which was written by a member of the Church), can be downloaded for free.
In order to use this software, two downloads are required:
o
D70 Commander:
File name is D70 Commander vX.X
*Please note: the above URL is case-sensitive. If you type this in all lower-case, it will not work.
o
USB control driver:
A USB control driver is also required in order for your PC to recognize the AVDH-1 USB
interface. It’s called the Keyspan driver from Tripp-Lite. Drivers for various operating systems
are available – please choose the appropriate driver based on your operating system.
