Overview

ESW-R220

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 Lockâ„¢ 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: ESW-R210 UHF Synthesized True Diversity Receiver ESW-T211 UHF Synthesized UniPak® Body-pack Transmitter ESW-T212 UHF Synthesized Plug-on Transmitter ESW-T214 UHF Synthesized Handheld Microphone/Transmitter
