This system includes the PR 40 Receiver and the SO 40 Snapon Microphone Wireless Transmitter. The SO 40 snaps on almost any low impedance vocal microphone.

PR 40 diversity

Extremely light, rugged portable receiver
Two folding antennas
Four Level Diversity system for reliable reception
On/off switch with battery/status LED

The PR 40 is suited for many different applications.

The PR 40 features an ultra durable glass-fiber plastic case. The heavy-duty swivel joints on the antennas add to the reliability of the receiver. The PR 40 can be powered with two AAA size dry or rechargeable batteries. Integrated charging contacts allow the user to charge the batteries simply by placing the receiver in the CU 40 charger. The battery compartment also accepts a special adapter for powering the receiver from a camera or DC power supply.

The PR 40 provides fixed-line level and adjustable headphone level outputs. Metering includes RF, audio level and battery status LEDs. A preset squelch will mute the receiver if the received signal is too weak so the related noise or the self-noise of the receiver will not become audible when the transmitter is switched OFF.

The PR 40 operates on one fixed, quartz stabilized frequency in the 710 MHz to 865 MHz UHF carrier frequency range and uses two swiveling UHF antennas.

SO 40 snapon transmitter
Professional XLR connector matching all dynamic microphones
Ultra-light, glass fiber reinforced miniature case
Integrated charging contacts
Extremely low operating cost

The SO 40 snapon transmitter is probably the most cost efficient way to upgrade a hardwire microphone for wireless use. All you have to do is disconnect the microphone cable and plug the snapon transmitter into the XLR connector on the microphone. The snapon transmitter with its small and light glass fiber reinforced case will add less weight to the microphone than the cable did.
An input gain control lets you match the SO 40 to the microphone output level. A noiseless on/off switch allows you to mute any microphone with no on/off switch. Integrated charging contacts and the optional CU 40 charging unit make recharging batteries easier than ever. Replaceable color code elements allow easy identification of the various microphone channels in any multichannel concert setup.
