ESW-R210

Overview

ESW-R210

The rugged, all-metal ESW-R210 receiver offers 100 PLL-synthesized UHF frequencies, Tone Lock™ tone squelch and True Diversity reception with two antennas feeding two completely independent RF sections. Automatic logic circuitry continuously compares and selects the superior received signal, providing more reliable reception, and reducing dropouts. The ESW-R210 provides +12V DC on the antenna jacks to power in-line RF devices, and has two audio outputs on the back panel: XLRM-type balanced and ¼” unbalanced. Two isolated audio outputs permit simultaneous feeds to both unbalanced and balanced inputs. A headphone jack with level control on the receiver’s front panel provides convenient monitoring of audio output.
