Wireless monitoring system

PR-90, as a new generation of wireless monitoring system, provides freedom of movement and natural, dynamic sound. Switchable mono, stereo, and focus monitoring modes as well as adjustable EQ and limiter functions permit natural sound reproduction. For any application, with a frequency response of 50Hz-15kHz, a high S/N ratio, and low THD, PR-90 allows each band member to better focus on his performance, and thus, be in harmony with his band mate.

With lightweight and small size, the PR-90 series provides unrestricted movement while delivering crystal clear vocals and instrument sounds with extended frequency response. It can satisfy the demanding requirements of broadcasting, recording and performance.
