Samson Concert 77 Wireless Handheld Microphone System

Samson Technologies was founded 20 years ago when they introduced some of the first affordable wireless technology ever. The latest line of wireless gear in that tradition is Concert 77. UHF quality diversity wireless that anyone can afford!

This system features a Samson HT7 Handheld Transmitter with a Samson Q7 Dynamic Microphone, plus a CR77 Wireless UHF Receiver. The Q7 is an all-purpose professional-quality vocal microphone.

The heart of Concert 77 is the CR77 Receiver. This true-diversity half-rack unit with PLL frequency control works with all of the Concert 77 transmitters. Rugged, durable and crystal clear with incredible range. UHF (Ultra High Frequency) means clearer frequencies with less interference.
