Especially designed to meet the high demands of the broadcast, film production, and live entertainment industries. This is the most advanced, high fidelity, IFB cueing, and remote program monitoring receiver available. While maintaining small size, outstanding reliability, and low power consumption, it can operate on any one of 113 channels. The PR-25 receiver incorporates a high performance RF section with low noise RF preamplifiers incorporating a dual tracking preselector system. A balanced diode ring mixer is used to enhance intermod rejection for unsurpassed performance even in crowded RF environments. An ultra-abrupt quieting detector circuit offers high signal-to-noise performance (up to 90 dB of quieting), even under adverse multi-channel operation while maintaining a frequency response of 50 to 12000 Hz. The audio output will accommodate a 3.5 mm stereo or mono low impedance headset. A feedback type volume control allows a 50 dB range of audio level. The PR-25 synthesized Pro Listener Series receiver can offer fail-safe operation up to 1000 feet when used with the COMTEK BST-25 Base Station Transmitter.
