VL Design Online VLD-ZM-1P Impedance Meter Plus Protection Relay

Impedance Meter Plus Protection Relay The VL Design ZM1P measures the impedance of loudspeakers and entire distributed loudspeaker systems as well as individual components. It will also calculate the wattage that will be produced on an installed loudspeaker system. The ZM1P also has an Overload Protection Circuit that prevents the meter from being damaged from amplifier overloads up to 120 VAC and a Tone Generator to improve system testing and performance.Power Requirements ZM1P - Eight -"AA-" Alkaline Batteries.Specifications:.
