• Truly a one-cable connection- a single CAT5 cable carries both power and signal from the WIR TX75 C/D to the slaves
• 5-year warranty
• System includes
  (1) WIR TX 75 S infrared slave emitter
  (1) WCA 096 12" CAT5 cable
  (1) WCA 091 25’ CAT5 cable
  (1) MLB 003 slave linking bar

Optional: white colored faceplate

Sleep/Power Save Mode

Shuts off carrier when no audio is present for 3 minutes

Modulation

FM Wideband, more or less 50kHz deviation max, 50 μS pre-emphasis

Carrier Frequencies

2.3MHz (Ch1) and 2.8MHz (Ch2). Default at power on = carriers off. Carriers are automatically enabled upon presence of audio.

Slave Coverage Area

Note: Slave emitter cannot be used without a master transmitter, but if the slave emitter is aimed so that its coverage area does not overlap that of the master, on its own it will provide:
12,000 sq. ft. (464 sq. m.) in single-channel mode with the RX22-4 receiver
6,000 sq. ft. (557 sq. m.) in single-channel mode with the RX15-2 receiver
4,000 sq. ft. (186 sq. m.) in single-channel mode with the RX18 receiver

Master + Slave Coverage Area (minimum, 1-ch mode)

If slave transmitters are aimed to maximize coverage area (so that their coverage areas minimally overlap that of the master):
24,000 sq. ft. (2,230 sq. m) in single channel mode with the RX22-4, a master and (1) slave transmitter
36,000 sq. ft. (3,345 sq. m) in single channel mode with the RX22-4, a master and (2) slave transmitters

Indicators On/Off

2-position switch turns on/off indicator lights

Signal-to-Noise Ratio

70 dB, (line input)

Frequency Response

95Hz to 17.6kHz, -3dB re 1kHz (line input)
125Hz to 17.0kHz, -3dB re 1kHz (microphone input)

Total Harmonic Distortion

Less than 1 percent (1 kHz, nominal deviation, line or microphone input)

From Master Input

8p8c RJ45 connector input provides 48VDC 0.4A power, baseband RF, and a bi-directional RS-485 bus for control and status communications.
