Samson Concert 77 lapel wireless system is an ideal solution for any professional application. The Concert 77 lapel wireless provides high performance UHF True-Diversity Wireless at an incredible price. The Concert 77 UHF Wireless systems feature half rack space/dual antenna receivers with 6 segment audio and RF metering, volume and squelch controls, 1/4-inch unbalanced and XLR balanced outputs (switchable mic/line level), a rugged beltpacks transmitter with On/Off and Audio Mute switches, a battery meter, and audio level controls.
Samson Concert 77 Headset Wireless Features
- True Diversity UHF Wireless System with PLL Frequency Control
- Multi-segment Audio level, RF level and A/B Antenna Operation LED meters
- Squelch control eliminates carrier signal noise and RF interference
- Tuned molded antennas for accurate reception
- XLR and unbalanced 1/4-inch outputs with mic/line level output switch
- Includes CR77 receiver, LM10 omni-directional lapel microphone and CT7 beltpack transmitter
- Operating Frequencies: USA 642.375 - 645.750 mHz (N1-N6)
The CT7 beltpack transmitter is configured as a headset system thanks to the popular locking P3 input connection. The CT7 also features a three-segment battery indicator, separate power and audio on/off switches, adjustable AF level (audio gain), and 12-hours of battery life on a single 9-volt battery.
The CR77 true-diversity half-rack UHF receiver is the core of the Concert77 system. The new synthesized PLL frequency control circuitry keeps the signal locked and true while dual tuned molded antennas with LEDs monitor the true-diversity operation. The CR77 features a front panel display with large multi-segment Audio level and RF level LED meters, and a large rotary volume knob allows easy adjustment of audio output. The rear panel features balanced XLR and un-balanced 1/4-inch outputs allowing flexible connection options. Two CR77 receivers can be rack mounted together in a single space rack adapter available as an added accessory.
