ESW-R220 UHF Synthesized True Diversity Dual Receiver (DISCONTINUED)
100 total
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.
- 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:
