Wireless microphone systems are vulnerable to dropouts, (momentary loss of audio) and it is often difficult to pinpoint the exact cause of the problem. Dropouts can be caused by improper antenna positioning, defective antenna cabling, a problem with the transmitter, a problem with the receiver, a problem with the sound system. [. . . ] Some Crestron system controllers with RF interfaces are set at the factory to spread signal throughout the entire 2. 4GHz band. Not only will this interfere with the SWM7000, it will interfere with your LAN, Bluetooth, etc devices. Crestron gives instructions explaining how the reconfigure their controller so that it only uses 1/7 of the spectrum (www. crestron. com). This leaves plenty of room for your SWM7000 system and Crestron to work together without interference. It is important to note that some receivers will not operate reliably below channel 15. Selecting any channel above 42 takes you out of the license-free band. We recommend temporarily using channels 50 through 65 for testing. 7 of 13 3. If your SWM7000 system does not sound as good as a wired mic, something is out of adjustment. The first thing to try is to plug a wired mic into the receiver's audio-out cord. If the system still sounds bad, your problem is downstream of the receiver. If the problem is definitely with the SMW7000, bypass all functions to identify the cause. Bypass the FBX, set the compressor ratio to 1:1, set the de-esser to 0, set the mic model to NONE, set the output level to -10dB, or simply load the System Default program. Then add the other functions in one at a time until you find the function that is out of adjustment. The default PAD setting on the transmitter may be too high for loud programs or very hot belt-pack mics. If so, open the case, press select until the pad blinks and use the down arrow to set a deeper pad setting. Pad settings range from 0 (no pad) to -40 dB (recommended for high-output mics such as the Voice Technologies SVT70 series available from Sabine). Two mics on the same channel If you turn on a mic and it screeches and sounds grossly distorted, there is probably another mic on that some channel within 100 meters. If there is no output with several transmitters, the problem is mostly with the receiver. If your receiver is showing audio input in the LCD window, check your output level on the front panel. Current versions of the receiver show the maximum output level as +00 and mute as -00. In any case, we recommend you set your output to -10dB for most applications and adjust the trim tab on the mixer as needed. If your handheld transmitter does not show any audio bars, unscrew the mic head, and inspect the four pogo pins. [. . . ] You may need to manually show your computer the location of the USB driver for your SWM7000 receiver. This should happen automatically, but occasionally you will have to do the following: Connect your receiver to your computer using the USB connection. You should see a Windows display indicating a USB device has been found. Click on the display and you should get a Windows Wizard asking to install this new device. [. . . ]
