Description
The MiniSPL is the ideal accessory for the Acoustilyzer AL1 and Minilyzer ML1. Its self-powered design, the individual factory adjustment and the auto power-off control combine to make MiniSPL an accurate, easy to handle yet affordable measurement microphone.
The servo-loop output stage design supports long cable connections between the analyzer and the microphone - up to several hundred meters. MiniSPL is also recommended and easy to use in conjunction with PC based measurement systems with high quality audio cards.The MiniSPL measurement microphone includes following additional items: 1x Windscreen; 1x Microphone-holder + Adapter 5/8" - 3/8"Features:
- 1/2" Measurement Mic
- Battery Powered
- Balanced Output
- Omni-directional
- Individually Adjusted
- Auto Power-Off Control
