The PM3180 amplifier incorporates three independent amplifier channels with a unique digital interface, providing the ideal solution for restaurant, lounge/bar hotel, factory or similar facilities where multiple program and paging inputs need to be distributed to separate areas and automatically switched. The PM3180 provides up to 4 AUX inputs and 2 MIC inputs that can be individually assigned to each amplifier channel (one of the mic inputs can be programmed for telephone paging applications). Each input on a particular channel can also be assigned a priority level; the amp channel will then automatically switch inputs based on input activity. Microphones can be assigned to the highest priority levels: 1 or 2; and aux sources to levels 3, 4, 5, or 6. For example, a paging microphone can be assigned priority level 1, a jukebox to level 3, and a radio to level 4. In this configuration, the radio will play until the jukebox becomes active; both inputs are overridden when the page microphone is activated. The three integrated amplifier channels are rated at 100, 60, and 20 watts. All amplifiers have separate 4- and 8-ohm outputs as well as 25 and 70 volt taps. Audio processing inserts are also included for each amp channel to facilitate the connection of external signal processing equipment. Adjustable input trim controls adjust for differing audio source input levels. The PM3180 includes a variety of useful features, including phantom power and automatic level control for microphones, choice of microphone precedence activation (VOX, Contact N.O., Contact N.C.), variable mute, and automatic fade-in of audio source after a mic page or when switching to a lower priority. All control functions can be adjusted from the front control panel, which is itself removable for installation in a remote location away from the amp chassis. An infrared wireless remote control unit is also included and permits full control of all functions. The amplifier has a user mode that lets personnel adjust the volume, bass and treble levels and manually select input sources. A separate programming mode lets the installer customize system operation, including the ability to preset the powerup volume level of each input, preset treble and bass responses, and lock-out or inhibit volume, bass and treble controls, set priorities, and many more system parameters. All programming steps are displayed and verified on the unit’s large alphanumeric LED display panel. Programming can be accomplished using the control panel or infrared remote control unit. All programming is password-protected. With tremendous flexibility, the PM3180 provides an elegant solution to multi-zone sound management. 100, 60, and 20 watt channels 6 Priority levels with auto-switching 4 Auxiliary inputs 2 Microphone inputs; one converts to a telephone input Wireless infrared remote controller Volume and tone control lockout User programmable LED display Remote mountable front display panel Password-protected system settings Simple programming of system settings 3 Independent audio channels Mounting kits available for wall (RMPWMK3) or rack (RPK79) UL/ETL Listed
