Microphone Calibrator

Description

94 and 114dB sound level meter precision calibrator with output frequency of 1000 ±1Hz. These have an LCD display which shows the selected dB level.

• Fits 7mm (1/4″), ½ inch, and 1 inch microphones (includes 1/4 inch and ½ inch adapters)
• Low distortion output
• Easy one-handed operation with low battery indicator
• Every calibrator is tested by Studio Six Digital and verified to meet +/- 0.1dB at 94 and 114dB
• Includes AAA batteries

Specifications
