Review: Excellent troubleshooting device! - We just finished installing a 70 volt audio distribution system in a 250,000 square foot warehouse and the ZM-1P was invaluable in this installation. It allowed us to confirm the total wattage of the connected speakers on each zone as we completed them and the tone generator although not amplified was able to drive the speakers with enough signal level to confirm their operation. I would highly recommend the ZM-1P to anyone installing constant voltage audio distribution system.s

This is a must tool if you work on paging systems, we take care of 192 grocery stores and in 10 min. I can have this setup and tell you if there is a short or if you have a bad amp. Well worth the investment.
