The 3000 Series Whole-House Distribution Systems are easy to install and operate. The CP-3015 is a dual input system that accepts a CATV or antenna input in addition to audio/video signals from one video source and modulates it to a user selected channel that can be seen at four TV locations. Model CP-3025 & CP-3025XA a triple input systems that accept a CATV or antenna input in addition to two audio/video sources and modulates them to user selected channels that can be seen at up to five TV locations. The CP-3025XA requires external amplification with either a CP-DA520A bidirectional amplifier (when a bidirectional cable box is in use) or with a CP-DA500A amplifier when an external antenna is used in an area where signal strengths vary and high headroom is needed. All units output CATV channels 65-125 (ex 95-99) & UHF 14-64.
