Complete PA Speaker System with Automated Announcement/Messaging Unit & Music Player. Schedule pre-recorded messages, shift changes & music to play at certain times of the day. 

Our automated warehouse PA system comes complete with a 100V 120W mixer amplifier, automated digital messaging unit, a choice of 4, 6 or 8 wall-mount or pendant speakers, and a 100m drum of 2-core speaker cable.

The automated messaging unit can store up to 99 pre-recorded messages, music files, or audio alerts all of which can be programmed to play at certain times of the day and different days of the week.

This PA system is designed to amplify pre-recorded announcements, shift changes & general public address messages across whole warehouse spaces. In addition to this our 100V PA system can also be used for music/radio playback. Simply connect a smartphone, laptop or radio to the line input on the amplifier and start streaming music. 

Connecting the automated announcement system into CH1 on the amplifier will provide you with a priority function. This means when an announcement/message starts playing from the messaging unit the amplifier will mute all of the other inputs meaning a message can be heard loud and clear. Once the message has then stopped the music on the amp will continue to play.

Microphone input for making live announcements which will override the rest of the system. This means real-time public address alerts can be made in case of an emergency.
