The SMD Audio Multimeter AMM-1 is an advanced tool designed for audio enthusiasts and professionals. Its purpose is to provide accurate measurements and analysis of audio amplifier power output, voltage drops, impedance, phase difference, tuning frequencies, and more. With this tool, users can achieve optimal performance and efficiency in their audio systems.

One of the key features of the AMM-1 is its ability to measure true amplifier power output into any load, whether reactive or resistive. This allows users to accurately determine the actual power being delivered by their amplifiers, ensuring optimal performance and preventing damage to the system.

The AMM-1 also allows users to measure common DC voltages, making it useful for various applications such as measuring voltage drops during quick transients on cable runs or battery/charging systems.

With its impedance measurement capabilities, users can determine the impedance of speakers at any power or frequency from 20Hz to 1kHz. This is particularly useful for assessing speaker performance and ensuring proper matching with amplifiers.

The tool also enables users to measure the phase difference between voltage and current into reactive loads, also known as power factor. By understanding the power factor, users can optimize the efficiency of their audio systems.

Additionally, the AMM-1 can be used to find the tuning frequency of subwoofer enclosures and tune them for maximum power transfer. This ensures that subwoofers perform at their best, delivering deep and accurate bass.

Other features include measuring AC volts and amps, apparent power output, phase angle, real power, and frequency of a sine wave. This allows users to accurately assess the performance and consumption of their audio amplifiers or appliances that run on AC power.

The AMM-1 comes with essential accessories such as a protective silicon rubber boot, harness, and a comprehensive manual. Additionally, it features a battery self-test and display of condition, ensuring reliable and accurate measurements.

In conclusion, the SMD Audio Multimeter AMM-1 is a powerful and versatile tool that enables users to measure various parameters in audio systems. With its comprehensive range of measurement capabilities and accessories, it is a must-have for audio enthusiasts and professionals who seek precision and optimal performance in their setups.
