Noise Tester
Product ID: NC-16-2
The equipment is for monitoring the ambient noise in PA zone, and automatically control the output power of PA system, to keep the broadcast volume higher than the ambient noise.
- Audio input impedance: >= 20 K ohm
- Audio output impedance:
- Measuring ambient is adopted in noise testing circuit, the equipment is with high common mode rejection ratio, capable to test accurately the exact noise level at each testing point.
- In each PA zone the noise samples are taken from three testing points, and sent to the single chip via AID switch circuit for software comparison process consequently the anti-interference ability of the equipment is improved.
- Language distingue wishing circuit distinguishes the intermittence of long age automatically, and takes samples at the testing point during the intermittence to insure the reliability of sampling data.
- Two operate modes of manual and automatic.
- Convenient for operation and maintenance.
