  • Page 3: Introduction

    Introduction PX-8240 is a MCU controlled six-Zone mixing amplifier. With the MCU in PX-8240 and other connected unit such as PPS-06, PWP-06, and PEX-8000 construct a MCU data communication system. It would be able to expand output Zones and to have different announce mode of background music (BGM) and call signal.
