🔊 Product Overview

The TOA ZM-104A is a portable impedance meter designed for measuring AC impedance in speaker lines, which cannot be measured with standard multimeters.

With simple, tester-like operation, this unit allows quick and reliable on-site inspection and troubleshooting of speaker systems—especially in PA (public address) and emergency broadcast systems.

By switching between three measurement ranges, the ZM-104A supports a wide spectrum from low to high impedance, making it suitable for various audio installations.

It also includes a handy impedance-to-power conversion chart, enabling users to easily estimate wattage from measured values.
