Shure Beta 58A Microphone with PGX2 Transmitter
In the tradition of the SM58, the Beta 58A dynamic microphone has become a top choice among vocalists and touring sound professionals.
The Shure Beta 58A is a high-output supercardioid dynamic vocal microphone designed for professional sound reinforcement and project studio recording. It maintains a true supercardioid pattern throughout its frequency range. This insures high gain-before-feedback, maximum isolation from other sound sources, and minimum off-axis tone coloration. The Beta 58A has a shaped frequency response that is ideal for close-up vocals. The superb performance of this microphone is not affected by rough handling because of its rugged construction, proven shock mount system, and hardened steel mesh grille. Typical applications for the Beta 58A include lead vocals, backup vocals and speech.

Channel J6: 572.250 to 589.875 MHz
Channel L5: 644.000 to 662.000 MHz
System Working Range: 100 m (300 ft.)
Note: actual range depends on RF signal absorption, reflection, and interference
Audio Frequency Response (+/- 2 dB):
Minimum: 45 Hz
Maximum: 15 kHz
(Overall system frequency depends on microphone element.)
Total Harmonic Distortion (Ref. +/- 33 kHz deviation, 1 kHz tone): 0.5 %, typical
Dynamic Range: >100 dB A-weighted
Operating Temperature Range:
18 deg. C (0 deg. F) to 50 deg. C (122 deg. F)
Note: battery characteristics may limit this range
Transmitter Audio Polarity:
Positive pressure on microphone diaphragm (or positive voltage applied to tip of WA302 phone plug) produces positive voltage on pin 2 (with respect to pin 3 of low impedance output) and the tip of the high impedance 1/4-inch output.
