The Modulator is a solid state high performance frequency agile headend modulator, allowing system reconfiguration at the push of a button. The button is located behind the front panel, beside the channel display. A small plastic tool or pen is used and inserted through the hole to advance the channel. Last data entry to select channels is automatically stored in nonvolatile memory. After powerfailure, the unit initializes to the set channel when power comes on.
Adjustments are for video level, sound carrier, audio level and rf-output.
Audio input is 600 Ohms unbalanced. If-Loop is unfiltered. Last channel location is stored in nonvolatile memory. No battery back up is needed in case of power failure. IF-Loop is unfiltered.
