Valcom’s Stacking Feedback Eliminator is designed to eliminate acoustic feedback and act as a message stacker. When a voice page is made, the message is digitized and saved. Upon completion of the live page, the message is released for broadcast over the speakers.

• Multiple messages can be recorded simultaneously – records a page while playing a recorded page
• One unit eliminates feedback to all zones
• Automatic consistent volume level even when recording, voices vary – low to high
• High-fidelity – sounds like a natural voice not like a recording
• LED indicators for play, record, busy, power
• Dip-switch programmable features:
• Pre-announce alert tone
• Priority override (real time or delayed)
• DTMF message cancel
• Real time background music with volume control
• Two audio outputs: 8 or 600 Ohms loop
• Power Requirements: -24Vdc, 250mA
• Emergency messages can interrupt play back sequence (interrupted message will play in full once emergency message has completed)
