The Polsen CAM-2W is a 2-channel wireless microphone system that is designed for hands-free mobility in a wide variety of applications including video production, electronic news gathering (ENG), electronic field productions (EFP), and classroom and presentation applications. It is a reliable, easy-to-use solution for wireless sound transmission. The CAM-2W includes an omnidirectional microphone (PL-2W), which is ideal for ENG and EFP video applications since omnidirectional microphones are minimally susceptible to wind and handling noise. The PL-2W also provides flexible placement options and allows for head movement without affecting the sound. The CAM-2W system was designed with two switchable frequencies to avoid interference while operating at a range of up to 100 feet (300 feet in optimal conditions). A durable and flexible antenna that can be positioned for the best possible reception is included. Audio can be monitored in real time with the included earphone. A tie clip for wardrobe placement and a windscreen that reduces wind noise and vocal plosives are also included. The CAM-2W system is a compander-free system for delivering high-quality audio. In most wireless systems, the audio signal is compressed in the transmitter and then expanded in the receiver causing undesirable artifacts such as pumping and breathing. Compander-free systems don't exhibit these artifacts making them a favored solution among filmmakers around the world.
