{"product_id":"toa-pm-660u","title":"TOA PM-660U Desktop Paging Microphone With PTT Switch","description":"\u003cp\u003eThe TOA PM-660U is a moving-coil desktop microphone engineered for permanent install environments where reliable paging and public address are operationally critical. System integrators deploying corporate, institutional, or facility-wide PA systems will find the balanced 600-ohm output and anti-vibration construction essential for maintaining clean signal integrity across long cable runs in noisy electrical environments.\u003c\/p\u003e\u003cp\u003eThe PTT switch assembly combines a push-to-talk action with a locking lever that holds the mic open during extended announcements, reducing operator fatigue without requiring a separate footswitch or relay. A built-in remote control contact, interlocked with the talk switch, allows direct triggering of amplifier power-on or chime tones without additional relay hardware, simplifying rack-side integration. The 4-conductor shielded unterminated cable gives installers flexibility to terminate to any connector type required by the system.\u003c\/p\u003e\u003cp\u003eCompared to consumer desktop mics, the PM-660U is purpose-built for install: ABS resin housing, zinc-plated steel wire grille, and a rated operating temperature and humidity range suit it for equipment rooms, reception desks, and dispatch consoles where the mic must perform unattended for years without service calls.\u003c\/p\u003e","brand":"TOA","offers":[{"title":"Default Title","offer_id":51443047727288,"sku":"47106","price":186.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/47106_TOA-PM-660U-Desktop-Paging-Microphone-With-PTT-Switch_ALT01sqr.jpg?v=1789136436","url":"https:\/\/soundpro.com\/products\/toa-pm-660u","provider":"SoundPro","version":"1.0","type":"link"}
