Installation
The VDA-6830 module can be installed in a Leitch FR-680x or FR-7001 series frame, or an FR-7000MB MIX BOX frame. If this module is installed in an FR-7001 series or FR-7000 MB MIX BOX frame, a 6800-M back module is required.
There is no need to terminate unused outputs; however, doing so will improve response.
A jumper near the board connector provides a selection of input impedance between 75 and high impedance. This jumper should be removed if high-input impedance is required.
Operational Adjustments
The potentiometer is factory set, and re-adjustment is not recommended without precise test equipment.
A multi-turn Gain potentiometer provides adjustment over a range of -3 to +3 dB. A single-turn potentiometer allows fine adjustment of the high-frequency Response (10-30 MHz).The gain is increased when the potentiometer is adjusted clockwise.
Both the Gain and Response controls are located on the front edge of the module.
