EN-PA500

en 54  PA public address and voice alarm system Master Control Unit with built-in 500W Class-D amplifier

EN-PA500-controller is the core unit of Voicewell VA/PA system which performs the audio storage, signal processing, routing, control and supervision functions for the whole system. With the built-in 500W Class-D amplifier, the single controller can work as an 8-zone VA/PA system. When more power and speaker zones are needed, it can be expanded by using external power amplifier PA-MCU and zone expander PA-ZONE8/PA-ZONE24.

Functions:
The controller integrates multiple functions such as audio storage, playback, zone control, audio monitoring, scheduled broadcast and fault diagnosis, etc.

Automatic fault diagnosis
The INTEVIO system is a fully monitored system with the ability to supervise and report faults related to the main power, backup power, CPU, microphone, amplifiers, speaker circuits and the dry contacts. The fault details will be displayed on the LCD screen and fault logs will be stored in the internal memory.

Allow all calls even when the CPU malfunctions

If the CPU of the PA-MCU fails the Voicewell system will still allow the user to make paging announcements (All Call) using the PTT Microphone or the call stations in case of emergencies.

Scheduled broadcast with built-in timer

PA-MCU has a built-in timer and supports configurable scheduled broadcast without extra timing device.

Record and play

PA-MCU allows user to record temporary messages into its built-in 1GB memory with the PTT microphone or the call station and broadcast it without configuration. It’s a function for operation efficiency improvement, especially for the application such as shopping mall/supermarket where the promotion message needs to be frequently updated.

Cost saving amplifier backup solution

PA-MCU has built-in amplifier automatic switch-over function and allows different amplifier backup configurations to address
the needs of different applications. To back up all the amplifiers in the system, a minimum of one standby amplifier is sufficient,
which greatly reduces the ownership cost on standby amplifiers.
