WR-358LD 2-Channel VHF Microphone The WR-358LD VHF microphone is a professional audio solution combining functionality and high sound quality. This system, equipped with two handheld microphones, provides reliable transmission and flexibility for various applications such as live performances, presentations, and conferences. High Transmission Quality The WR-358LD system operates in the carrier frequency range of 170 to 270 MHz, ensuring stable and clear signal transmission thanks to FM modulation and precise frequency stabilization with an accuracy of +/- 0.005%. A frequency response of 40 Hz to 20 kHz, along with a high signal-to-noise ratio of over 100 dB and a dynamic range exceeding 100 dB, guarantees exceptional sound quality. Maximum deviation of +/- 15 kHz and low distortion (T.H.D. <0.5%) ensure accurate sound reproduction. A range of up to 50 meters and a wide operating temperature range from -10 to 50°C allow for use in various conditions. Receiver with Precise Stabilization The WR-358LD microphone receiver offers quartz-controlled frequency stabilization, ensuring reliable and accurate reception. Reception sensitivity with a signal-to-noise ratio of 60 dB (12 dBU) and audio output level of 0~0.5 V at 5 kOhm for CHA+B channels and 0~0.5 V at 50 kOhm for CHA&CHB channels guarantee high audio signal quality. The 13-15 V, 500 mA AC adapter ensures stable receiver operation. High-Performance Handheld Microphones The set includes two handheld microphones featuring an RF output power of up to 30 mW and low harmonic emission (over 45 dB of the carrier wave). The built-in antenna and unidirectional microphone characteristics ensure precise sound capture. The microphones are powered by two AA batteries, ensuring convenient use and long-lasting operation.
