How To Install A Wireless Microphone? |
Installing a wireless microphone is not only plugging in and turning it up. But, a few steps ahead of it. Always keep in mind the following steps, before installing your wireless microphone:
- Always start with a fresh battery, regardless of whatever type of transmitter you have. Battery life varies from system to system; check your manual. Keep in mind, if your battery has served more than half the listed life, the best option is to replace it.
- Ensure that your transmitter is off.
- Turn on your receiver.
- If the system has Automatic Frequency Selection, then press the receiver's "Select" button, and the scanning will begin, so as to find a suitable frequency.
- Temporarily turn down the receiver's volume or level control.
- Turn on the transmitter.
- If the system has Automatic Transmitter Setup, press the transmitter's "Sync" button. It will lock on to the receiver's selected frequency. Check the receiver's LED or meter to confirm that it's picking up the transmitter, and then turn the receiver's volume control up to a "normal" level.
- Now adjust the transmitter's audio gain. This is done to get a good sound and good levels.
- Perform a walk-around through the performance area while observing the receiver's "Power" LED or RF meter. It should indicate sufficient reception in all areas of coverage. If you feel a dropout, reposition the receiver or its antenna for better reception.
- Adjusting the proper input gain is the most important aspect. Setting too low, the signal-to-noise ratio of the system will suffer, or setting too high, severe distortion and/or compression of the dynamic range will occur. It is important to consider the features and controls offered on any wireless transmitter that enable accurate gain adjustment.
- The transmitter-to-receiver distance must also be controlled. As the transmitter moves farther away from the receiver, the overall signal-to-noise ratio grows worse as the transmitter signal gets weaker. When the system gets near the limit of its operating range, dropouts will become more frequent and a buildup of steady background noise (hiss) may be audible.
