The D'Amore Engineering / SMD IM-SG+ (Impedance Meter / Signal Generator PLUS) is a highly versatile and reliable product that offers a wide range of uses for professionals and enthusiasts in the audio industry. With its precision AC impedance meter and frequency range of 10hz-20khz, this device delivers accurate and detailed measurements.

Featuring an all-new auto-lock feature, the IM-SG+ eliminates the hassle of manually stopping the frequency knob at the desired position. Whether it's the top or bottom frequency, the auto-lock feature takes care of it for you, ensuring convenience and ease of use. Additionally, the super smooth operation of the frequency knob allows for precise adjustments.

One of the primary uses of the IM-SG+ is obtaining a driver's T/S parameters, which are crucial in designing optimal audio systems. It also enables users to quickly and safely locate stock speakers in vehicles, making it an essential tool for car audio installations. Moreover, it can determine speaker crossover set points, locate the tuning frequency of passive radiators, and determine the frequency of any enclosure, be it sealed, ported, or bandpass.

With the auto-lock feature, users can find the Fs (resonant frequency) of any speaker, ensuring proper tuning for optimal audio performance. The IM-SG+ also allows for the determination of box volume, even in odd-shaped sealed enclosures, and can test the impedance of long wire runs and RCA cables.

This device is not limited to speaker-related applications; it can also be used to find the crossover frequency of passive crossover networks, locate annoying rattles in vehicles, and function as a pink noise generator. Additionally, when used with an SMD AMM-1, it aids in determining "box rise" at a specified frequency, providing valuable insights for audio professionals.

The IM-SG+ comes with improved battery life, ensuring long-lasting performance, and its compact design makes it portable and easy to use in various settings. Its reliable functionality and wide range of applications make the D'Amore Engineering / SMD IM-SG+ (Impedance Meter / Signal Generator PLUS) an indispensable tool for anyone involved in the audio industry.
