TOA's PM-660U is an elegantly styled, compact deskmicrophone for use in public address, paging and radiocommunication systems. Ideal applications includerestaurants, offices, warehouses, transportation terminals, dispatch centers and entertainment facilities.
Its smooth, natural response provides high quality voice reproduction and excellent articulation to enhance the overall performance of your system. Compact and lightweight, the PM-660U requires a minimum of desk orcounter space and is easy to handle.
To significantly reduce background noise and feedback, the PM-660U features a cardioid pick-up pattern that is uniform over the entire frequency range. The dynamic microphone element has a 600 ohm balanced output and the microphone is supplied with an attached 8.2ft, four-conductor cable with stripped wire ends. Two conductors are shielded and are dedicated for the microphone signal. The other two unshielded conductors connect to an auxiliary, normally-open switch contact, used to activate external muting, priority or relay control circuits. The auxiliary switch contact is closed by using the push-to-talk bar, which also turns on the microphone by opening a second set of contacts that normally short the mic element. A locking lever is provided to keep the push-to-talk bar in the "on" position when the microphone must be kept open for an extended period.
A wire mesh grille protects the mic element and incorporates an internal wind screen to reduce poppingnoises from speech. Ideal for desktop or shelf mounting,the integral microphone stand/base is fitted with four, rubber isolated feet to reduce mechanical noise pick-up. Constructed of high impact ABS resin, the microphone is finished in a neutral dark gray with a prominent, orange push-to-talk button.
