The Alpha Communications® / Paso™ B500EX desk paging microphones clearly reflect a drastic departure from conventional push-to-talk desk base microphones. The flexible microphone arm permits multiple adjustments of height and angle. In addition to a conventional Push-To-Talk switch, the B500EX also has a Push-To-Lock switch.
The B500EX microphones are low-impedance, unidirectional dynamic microphones with a shock mount microphone cartridge and flexible gooseneck. The B500EX is supplied with a 15 ft. shielded cable and is attached to the die-cast base by a Female XLR connector (the Male XLR connector is built-in the base of the B500EX). Music muting is provided by the VOX Circuit of a Paso amplifier.
