Shure PGX24/SM58 Wireless Microphone System

PGX24/SM58 ميزات

SM58 frequency response tailored for vocals,

with brightened midrange and bass roll-off
The Frequency Agile UHF design provides up

to 90 selectable UHF frequencies that operate on an 18MHz UHF bandwidth
Diversity Reception system uses twin receiver circuits

to minimise noise and drop out caused by RF interference
Hi-quality sound with quick and easy setup using infrared

remote synchronization of channel and frequency status
Use 9 systems simultaneousy within the 846 - 865 Mhz range for big events
PGX4 has XLR and unbalanced 1/4 inch jack audio outputs
PGX2 includes mute switch and battery power warning lights - 8 hours

 battery life from 2 x AA 1.5v alkaline batteries
Rugged carry case and batteries

and mic clip included with this microphone


SM58 مواصفات

Type: Dynamic (moving coil)
Frequency Response: 50 to 15,000 Hz
Polar Pattern: Unidirectional (cardioid), rotationally symmetrical

about microphone axis, uniform with frequency
Sensitivity (at 1,000 Hz Open Circuit Voltage):

–54.5 dBV/Pa (1.85 mV) 1 Pa = 94 dB SPL


PGX مواصفات نظام

Working Range: 100m (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 degrees C (0 degrees F)

to +50 degrees C (+122 degrees 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


PGX2 مواصفات

Audio Input Level: +2 dBV maximum at -10dB position,

-8 dBV maximum at 0dB position
Gain Adjustment Range: 10dB
