PF Series Intelligent Amplifiers

Passive, powered or networked: you can choose the CF/CFX system that suits your needs at any time. At the factory or in the field, the CFX passive connector plate can be easily replaced by a PF1-200 or PF1-500 Class D digital amplifier with loudspeaker specific processing. Their lightweight switching power supplies deliver 70% efficiency at full output, reducing AC requirements and eliminating the need for a cooling fan.

Whenever you are ready for Ethernet audio networking, your CF/CFX loudspeakers are too; just replace the connector plate with a PF1-200R or PF1-500R RHAON empowered amplifier equipped for connection to the Renkus-Heinz Audio Operations Network. RHAON empowers you with CobraNet digital audio distribution, user configurable DSP for maximum control, remote systems management from any Windows computer, life safety functions and more – all using standard Ethernet hardware and cable.

If you need an outstanding high-power 15-inch 2-way system, order the CFX151 or CF151-5. For full-range nearfield applications, the CF151-2 with a 200 Watt PF1-200 is a logical choice. If you need Ethernet-based audio operations networking, order the CF151-2R or the CF151-5R; both are RHAON empowered.
