A professional PLL UHF RECEIVER, stabilized by a crystal of quartz, programmed esprcially for our devices.
Due to the special design, it is very stable, sensitive and powerful.
It is supplied with a sensitive RF input, and by using earphones, you will get one of the best receivers, designed especially for our transmitters and listening devices.
Our Crystal Controlled UHF transmitters (phone line transmitters, phone "adapters" transmitters, mains connected transmitters, VOXes and room transmitters, will match the receiver frequency.
This model has excellent reception circuit and great sound quality.
The high quality external earphones produce 70mW of crisp, clean audio power, allowing you to hear all the details of conversations.
It can be connected to a recorder.
One of the most important features is the option of connecting the earphones and a recorder at the same time.
This high quality receiver costs less than any Narrow-band scanner receiver or most of other professional receiver devices and it pairs perfectly to our professional transmitters.
This model was thoroughly tested with our transmitters in various conditions and we absolutely recommend it for use.
This PLL UHF CRYSTAL CONTROLLED RECEIVER can be used in a room or business, indoor or outdoor.
