Description

The DSM-1X SPL Meter allows you to measure how loud your sound system or live band is in order to protect both your equipment and hearing, as well as comply with legal regulations.

You can also use the meter to make sure your speakers are at the same level or to match your subwoofer(s) to your speakers.

The device features an easy-to-read 4-digit LCD display with selectable backlight. It includes selectable A/C weighting as well as a selectable fast/slow response for ranges measuring between 30 and 130 dB at 32 to 8000 Hz. A maximum, minimum, and instantaneous data hold selector allows you to capture the input at any time. An automatic out-of-range detector and an internal battery tester help ensure the unit operates as it should. A 9 VDC alkaline battery, a foam windscreen, and a miniature calibration screwdriver are included.

*Frequency-weightings correlate sound level meter (objective) measurements with the subjective human response. Our ears are frequency selective, being most sensitive between 500 Hz and 6,000 Hz, compared with the full range from 20 Hz up to 20,000 Hz.
