Poly Expansion Microphone - For Poly Studio USB & RP Debut

When used with Studio X50 and Studio USB, system base microphones are turned off and audio is only picked up by the expansion microphone. The only cable supported is the 7,6m that it ships with. Other cables are not available and custom cables are not supported. When used with the Studio X50 in reverberant, echoey rooms it will improve the X50 audio pick-up substantially. When used with the Studio USB the expansion microphone is an expansion only, replacing the Studio USBs internal microphone. Poly Studio USB will still be a solution for smaller rooms with the same level of audio pickup, but further out in the room. Compatible with: - Poly Studio X50 (without Trio/C60) - Poly Studio USB - RP Debut
