Introduction Overview The iVAM-1 is a 1RU multichannel multi-source audio/video monitor with basic 3G- SDI and analog inputs. It may also be purchased with a large variety of other inputs or these may be added later at the need arises. Refer to the Specifications section of this manual or contact Wohler Sales for more information.
under all of the following conditions: a. The equipment has been damaged in any way, such as when the power- supply cord or plug is damaged. b. Liquid had been spilled or objects have fallen onto the equipment. c. The equipment has been exposed to rain or moisture. d.
sympathetic vibrations, use thin card stock, felt, foam, or weather-stripping between the vibrating surfaces. Tie loose cables securely with cable ties. Mechanical Bracing The 1RU chassis is securely attached to the front panel. In addition, the chassis has mounting tabs through which you attach it to the rack rail. This feature will reduce or eliminate rear bracing requirements in many mobile/portable applications.
The iVAM can be operated easily and simply from controls on its front panel, as described in this chapter. It may be accessed remotely in two ways, via the Wohler Web GUI for administrative purposes or by third party equipment via Application Programming Interface (API) commands.

2. AES termination: AES signals should have one and only one termination. This termination should physically be at the last destination of an AES coax cable. If the iVAM-1 is the last connection in a series of AES connections, then its terminations should be turned on. A symptom of too many terminations (or no termination) is that no signal appears to be present on the AES input.
Phase Configuration Touching the Phase Config selection on the Unit Settings Menu proceeds to the Phase Config Menu. This menu is shown in Figure 2-16. Figure 2-16: Phase Configuration Menu The controls function as follows: 1. Pair 1 - 8: These switches allow you to select which channel pairs will receive a phase meter on the Metering Screen.
