The modulators are used in ALCAD head stations. They are powered from FA-310 R912046 power supply. This professional equipment allows to distribute in antenna systems audio - video signals from various sources (CCTV cameras, satellite receivers etc.). Due to VSB modulation the modulators are suitable for professional cable TV systems (no spacing required).
