Ideal for airports, train stations, shopping malls, retail stores and museums, this unit enables the announcer to pre-record the announcement (3 minutes incl. Chime playback), play back the recorded message to the announcer and finally send to the listener if the announcer approves of the quality of the message. Maximum messages: 4 (requires 24V DC power supply)
