Telex PH-1 A4F Single-Sided Intercom Headset
The PH-1 is a medium-weight single-sided intercom headset built for operators who need one ear on the intercom and one ear on the room. The foam-filled cushion gives a light, comfortable feel with moderate isolation from ambient noise, so a camera operator or floor manager can wear it through a long call without fatigue while still hearing cues, cameras, and crew around them.
The dynamic noise-canceling boom microphone rides on a continuously adjustable ball joint that positions it precisely at the corner of the mouth and rejects stage and crowd noise around the wearer. A 6-foot cord terminates in a 4-pin female XLR (A4F) connector for the beltpack or user-station side. The dynamic capsule needs no phantom power and stands up to the knocks of daily production use.
