  • Overview

    The ESW-R220 dual receiver features two independent receivers, each with 100 PLL-synthesized UHF frequencies, in a rugged, shielded metal housing, along with an antenna distribution system. The integral antenna combiner/divider distribution system provides two pairs of antenna inputs and two pairs of antenna outputs. This allows the ESW-220 to be extremely flexible; for example, the additional inputs might be used when coverage of a split banquet/meeting room is difficult with a single pair of antennas, or when considerable multi-path interference is present. The antenna output jacks are provided to feed other wireless receivers operating in the same frequency band.
  • Features

    • Two independent receivers in a single housing along with an antenna distribution system

    • 100 PLL-synthesized channels selectable via push buttons

    • An integral antenna combiner/divider distribution system that provides two pairs of antenna inputs and two pairs of antenna outputs

    • +12V DC provided on the antenna inputs to power in-line RF devices

    • Auto-adjusting AC power supply accepts 120-240V 50/60 Hz input

    • Unit mounts in a single (1U) 19" rack space with included adapters

    • True Diversity operation selects the better signal from two independent tuner sections, reducing dropouts

    • Interference-resistant UHF band operation

    • Tone Lock™ tone squelch circuitry opens only for ESW transmitter signals

    • Balanced and unbalanced audio output jacks; ground-lift switch on balanced output

    • Front-panel headphone monitor jack with level control

    • Engineered Sound wireless transmitters and receivers are offered separately, rather than in pre-set combinations, to permit choosing exactly the right components for your particular application:
