Samson Concert 77 UHF TD Lapel Wireless LM10 Microphone SystemSamson 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
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.
