Looking to match multiple speakers to the correct power amplifier? The GoldLine ZM1P Impedance Meter Plus Protection Relay tool takes the guesswork out of setting up a distributed sound system so you can correctly match the impedance levels throughout an installation as well as the calculated watts required by your speakers.
The Gold Line 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.
