Shure-1288/PG30 UHF Wireless Microphone System (Shure-1288/PG30)

Working Range

75m (250 ft.) Note: actual range depends on RF signal absorption, reflection, and interference.

Audio Channel Response

Minimum: 45 Hz. Maximum: 15 kHz (overall system channel depends on microphone element).

Total Harmonic Distortion

0.5%, typical Ref. +/– 33 kHz deviation, 1 kHz tone

Dynamic Range
