The Samson Concert 77 wireless microphone systems bridge the gap between function, quality and price. Designed for sound reinforcement and public address applications, the Concert 77 provides a feature set that includes single channel UHF operation, diversity reception, high gain outputs and more. This system is a lavalier (lapel microphone) package and includes the CR77 receiver, CT7 body-pack transmitter and Samson LM5 lavalier microphone.

The CR 77 Receiver is a half-rack unit that uses AC power (adapter included) and features dual antennas, XLR balanced, and 1/4" phone unbalanced output connections. The dual antennas signify diversity operation, where dual receivers compete for the strongest possible reception. This further minimizes noise and drop-out due to radio frequency (RF) interference. Additional features include front level control and LED display of RF strength diversity operation and power.

The CT7 body-pack transmitter is light weight and features a P3 (mini 3-pin male) connection for the supplied lavalier, headset or line cable. The transmitter is powered with a single 9-volt battery. An Audio On/Off switch is separate from the power switch for added control without any accidental power downs. Although the output level is preset for mic or line level input devices, a gain adjustment dial is featured.

UHF Operation
UHF frequencies avoid the crowded air space VHF frequencies utilize. The result is minimal radio frequency noise and drop out.
Diversity Reception
The CR77 receiver features twin antennas and receiver circuits that compete for the strongest possible reception.
Light Weight Body Pack Transmitter
The CT7 body-pack transmitter is compact and lightweight with a P3 input connector for the included lavalier, headset or line level cable. The transmitter is powered via single 9-volt battery for up to 12 hours.
Separate On/Off & Mute Switches
The CT7 body-pack transmitter features and Audio On/Off switch that is separate from the actual power switch. This eliminates accidental power down.
