The Sennheiser EW 300 wireless microphone system belongs to Sennheiser's mid-tier professional wireless family, sitting above the 100 series with more advanced receivers, wider feature sets and the build quality demanded by working musicians, theatres, conference venues and broadcast users. EW 300 systems combine rugged transmitters with true diversity receivers housed in full-metal enclosures. Depending on the generation and set, they offer adaptive or true diversity reception, infrared synchronisation between transmitter and receiver, pilot tone squelch, auto frequency scanning and the HDX compander for transparent, distortion-free audio. Multiple tunable frequencies across wide UHF bandwidths allow several systems to operate together, which suits live events and installed sound in busy environments. The series is available in configurations for vocals, presentations and instruments, including handheld sets with premium cardioid capsules and bodypack sets with high-quality lavalier or headset microphones. For singers, public speakers, worship leaders and production companies that need more capability than entry-level wireless, the EW 300 family delivers professional reliability with straightforward operation. Note: the seller does not specify the exact generation, frequency range or included components, so please confirm the configuration before ordering.
