• Ensure the antenna selected is the best fit for your application. See the 72 MHz Antenna Selection Install
Guide on the Williams AV website for further advice. NOTE: The FCC requires this device to be used with
approved, FCC 15.203 compliant antennas and be professionally installed. Refer to Williams AV’s Antenna
Selection Install Guide for compliant antennas for this product.
Users complain of too much noise during soft audio� Dynamic range of music reduced too greatly�
• The transmitter could be set for High Compression (2:1) when Reduced Compression (1.5:1) or No
Compression (1:1) would be more suitable, given the program material. If so, set the Compression Ratio to 1.5:1
or 1:1 and see if this reduces the noise. See "Dynamic Range Compression" on page 13.
Buzz in other equipment when transmitter is on or off
• This is likely caused by incorrect audio connections, a ground loop, or defective equipment. To remedy, use
proper audio wiring practice to make connections.
Buzz or other noise in equipment only when transmitter is on
• Make certain the transmitter chassis is connected to the equipment cabinet rails if installed in a rack. Buzz/
hum in system may be experienced when the chassis is insufficiently grounded. In this case, install a ground
wire to the chassis and terminate to a verified ground source.
• Ensure antenna connections are secure.
• Select medium power output for the Power Output setting.
• Install transmitter at a distance from sensitive equipment.
• Use a remote antenna (ANT 005 or ANT 024).
• Make sensitive equipment more immune to RFI/EMI. The manufacturers of your audio equipment may
offer application notes for this purpose. Download Technical Bulletin: Buzz Or Hum Remedies from
the Williams AV website for suggestions for improving radio frequency (RF) immunity in existing audio
equipment.
