Wireless Monitoring Systems
10 per-set groups.Altogether 160 optional UHF Bands.
16 frequencies work simultaneity in the same band and
do not interfere.
No limit of  the receivers, infinite receivers can operate in the
same band.
LCD shows clear working status.
Optional stereo and mono modes.
Field strength and noise measure

Squelch quantum
adjustment control (prevention of interference noise
ifrom the environment).
