F M SYSTEMS, INC. announces a new concept in audio volume measurement. The AVM-Audio Volume Meter is a digital, hand-heldbattery operated, true RMS audio volume meter calibrated in dBm in a600 ohm circuit. Steady digital meter readings are obtained by storing and displaying only the highest RMS measurement made during the measuring interval.

The AVM meter reads audio levels in a 70dB range from +20 dBm to-50 dBm in 0.1dB steps with a basic accuracy of +1% +1 digit. Theaudio input can be either balanced or unbalanced and is high impedance bridging to the line being measured.

Live program audio can be measured as easily as test tones with the digital accuracy of the AVM. This meter reads true RMS, not average or peak volts, therefore dBm measurements reflect the true power content of the program audio and thus the loudness of the program.

This meter is particularly useful where several program sources must be adjusted to have the same loudness.
