Analogue sound level meter

Velleman AVM2050: Analog Sound Level Meter

Velleman AVM2050

The Velleman AVM2050 Analog Sound Level Meter

The Velleman AVM2050 sound meter is your perfect sound monitoring tool for measuring sound level checks, calibrating studio monitors, stage monitors, and other audio uses. This is a light-weight meter with an easy readout pane so you can take it on-the-go with you and use for measurements when traveling.


The AVM2050 connects to your recording/audio equipment via the output connector (RCA jack). You can switch the meter between fast or slow response times depending on the type of sound you're monitoring. The meter has seven sound levels, ranging from 50 to 126 decibels and both A and C weighting for sound analysis (A weighting for voice recordings, C weighting for instrumentals). Simply select your range from the turn dial on the face of the AVM2050. Measurements are most accurate when the meter is pointed in the direction of the noise source.


The Velleman AVM2050 has a battery life of 110 hours running on a 9V alkaline battery (included with the AVM2050). There is a battery test feature and an indication for when the battery is low and an option to switch the meter off to preserve battery even longer.
