5. Setup
Follow these steps to set up your Sennheiser XSW 1-ME2-A wireless system:
- Connect the Receiver:
- Connect the supplied power supply to the DC 12V input on the rear of the EM XSW 1 receiver and plug it into a power outlet.
- Attach the antennas to the antenna connectors on the rear of the receiver. Position them vertically for optimal reception.
- Connect the audio output (XLR or 1/4" jack) from the receiver to your mixing console, amplifier, or recording device. Ensure the Line/Mic switch is set appropriately for your input device.
- Install Batteries in Transmitter:
- Open the battery compartment of the SK XSW bodypack transmitter.
- Insert two AA batteries, observing the correct polarity (+/-).
- Close the battery compartment securely.
- Connect Lavalier Microphone:
- Plug the 3.5mm jack of the ME2-2 lavalier microphone into the microphone input on the SK XSW bodypack transmitter.
- Secure the microphone to your clothing, approximately 6-8 inches from your mouth, ensuring it is not covered by fabric.
- Power On and Synchronize:
- Press the power button on the EM XSW 1 receiver to turn it on.
- Press the power button on the SK XSW bodypack transmitter to turn it on.
- On the receiver, press the SET/SCAN button to initiate an automatic frequency scan. The receiver will find a clear frequency.
- Once a frequency is found, press the SYNC button on the receiver. Hold the transmitter close to the receiver's SYNC area (usually indicated) until the display confirms synchronization. The RF LED on the receiver should illuminate, indicating a successful connection.
- Adjust Audio Levels:
- Speak into the microphone at your normal speaking volume.
- Adjust the VOL+ / VOL- buttons on the receiver to set the output level. Monitor the audio input on your mixing console or amplifier to avoid clipping or distortion.
- Adjust the SQ (Squelch) control on the receiver's rear panel if you experience background noise when no audio signal is present. Increase the squelch level until the noise disappears, but do not set it too high as it may cut off desired audio.
6. Operating
Once the system is set up, follow these guidelines for operation:
- Microphone Placement: For optimal sound quality, ensure the lavalier microphone is positioned correctly and not obstructed.
- Battery Monitoring: Regularly check the battery status indicator on both the transmitter and receiver displays. Replace batteries when they are low to avoid unexpected signal loss.
- Range: Maintain a clear line of sight between the transmitter and receiver for best performance. Avoid placing the receiver near large metal objects or other RF-emitting devices.
- Mute Function: If the transmitter has a mute function (check specific model details), use it to temporarily silence the microphone without turning off the unit.
- Multiple Systems: If using multiple XSW 1 systems, ensure each system is synchronized to a different, clear frequency to prevent interference. The system supports up to 10 simultaneous channels.
7. Maintenance
Proper maintenance ensures the longevity and performance of your wireless system:
- Cleaning:
- Wipe the surfaces of the receiver and transmitter with a soft, dry, lint-free cloth.
- For the lavalier microphone, gently clean the windscreen if necessary. Avoid moisture.
- Do not use abrasive cleaners, solvents, or strong detergents.
- Battery Replacement:
- Replace AA batteries in the transmitter as soon as the low battery indicator appears.
- Always use fresh, high-quality alkaline or rechargeable AA batteries.
- Storage:
- When not in use for extended periods, remove batteries from the transmitter to prevent leakage.
- Store the system in a cool, dry place, away from direct sunlight and extreme temperatures.
- Keep components in their original packaging or a protective case to prevent physical damage.
