3. Setup Guide

3.1. EM-XSW 1 Receiver Setup

  1. Positioning: Place the EM-XSW 1 receiver in a stable location, away from large metal objects or other wireless devices that may cause interference. Ensure the integrated antennas have a clear line of sight to the transmitter.
  2. Power Connection: Connect the NT 12-5 CW power supply to the "Power" input on the rear of the receiver. Plug the power supply into an AC outlet.
  3. Audio Output: Connect the receiver's audio output to your mixer or amplifier.
    • For balanced output, use an XLR cable to connect the "Bal" output.
    • For unbalanced output, use a 1/4" (6.3mm) jack cable to connect the "Unbal" output.
  4. Output Level Adjustment: Use the "Line/Mic" switch on the rear panel to select the appropriate output level for your connected device. "Line" is for line-level inputs, "Mic" is for microphone-level inputs.
  5. Squelch Adjustment (SQ): The "SQ" knob adjusts the squelch threshold. This helps to suppress noise when the transmitter signal is weak or absent. Adjust as needed to prevent unwanted noise.

4. Operating Instructions

4.1. Powering On/Off

  • Receiver: Press the power button on the front panel of the EM-XSW 1 receiver. The display will illuminate.
  • Transmitter: Slide the power switch on the SK-XSW bodypack transmitter to the "ON" position. The display will show the current channel and battery status.

4.2. Automatic Frequency Management and Synchronization

The XSW 1 system features automatic frequency management for easy setup.

  1. Scan for Frequencies: On the EM-XSW 1 receiver, press the SET/SCAN button. The receiver will scan for available interference-free frequencies.
  2. Synchronize Transmitter: Once a frequency is found, the receiver display will prompt for synchronization. Hold the SK-XSW bodypack transmitter with its infrared window facing the receiver's infrared window (usually near the display). Press the SYNC button on the receiver. The frequency information will be transferred to the transmitter.
  3. Verification: After successful synchronization, the receiver's RF signal indicator and the transmitter's display will confirm the connection.

4.3. Manual Channel Selection (Optional)

If automatic scanning does not yield satisfactory results, you can manually select channels:

  1. On the EM-XSW 1 receiver, use the CH+ and CH- buttons to cycle through available channels.
  2. Once a desired channel is selected, perform the synchronization step (Section 4.2, Step 2) to transfer the channel to the transmitter.

4.4. Volume Control

Adjust the audio output level of the receiver using the VOL+ and VOL- buttons on the front panel of the EM-XSW 1 receiver. Monitor your mixer or amplifier's input levels to prevent clipping.

4.5. Mute Function

The SK-XSW bodypack transmitter features a mute switch. Slide the switch to mute or unmute the microphone. The transmitter's display will indicate the mute status.

5. Maintenance

5.1. Battery Replacement

The SK-XSW bodypack transmitter uses two AA batteries. When the battery indicator on the transmitter or receiver shows low power, replace both batteries with fresh alkaline batteries. Always dispose of used batteries responsibly.

5.2. Cleaning

  • Clean the receiver and transmitter surfaces with a soft, dry cloth.
  • For the headset microphone, gently wipe the boom and capsule with a slightly damp cloth. Avoid getting moisture into the microphone capsule.
  • Do not use cleaning agents containing solvents or abrasive materials.
