Guidelines For Best Performance - Electro-Voice R300 User Manual

4. Mute Function – press and hold on/off button for 2 seconds until MUTE appears in the LCD display, On
LED turns red, and sound mutes. Repeat to turn mute off.
3) Guidelines and recommendations for best performance.
Compatibility
The transmitter and receiver must be of the same frequency band and set to the same channel in order to
work together. The R300 is available in three frequency bands, A, B and E (Europe only). The band
information is available in the serial number label on the receiver, the serial number label on the handheld
transmitter, and on the back panel label on the bodypack.
Using Multiple Wireless Systems
If three or more R300 systems and/or other UHF/VHF wireless systems are being used in the same location,
proper frequency coordination is necessary to avoid interference. Some channels in the R300 are designed to
work together, see the channel maps in the back of the guide for more information. Contact your dealer or
Electro-Voice for assistance if you are planning more systems or using the R300 with other wireless
equipment.
Multiple Systems and R300
The ClearScan function can be used to set up any two R300 systems. Just scan with the first unit, set the
transmitter to that clear channel and leave it on. Then scan the second unit for another clear channel. If 3 or
more systems are used in the same room, put all of the channels in the same group as indicated by the
channel map on page XX.
Potential Sources of Interference
There are many potential sources of interference for your wireless system. Any electronic product that
contains digital circuitry including digital signal processors (reverb/multi-effects units), electronic keyboards,
digital lighting controllers, CD and DVD players, and computers, all emit RF energy that can adversely affect
the performance of your wireless system. It is always best to place the receiver as far away as possible from
these devices to minimize potential problems.
Analog and Digital Television stations can also interfere with your wireless system. The R300 is designed to
operate over 16MHz of RF bandwidth, which covers 3 US TV stations. If two of the three stations are used in
your area, it will severely limit the number of systems that will operate together and you should be using a
different band.
Battery Recommendations
Fresh AA alkaline batteries from a quality manufacturer will yield the best performance from your R300
transmitters. If sound quality degrades during use, it may be the result of a weakening battery.
Receiver and Antenna Placement
Do not place the receiver near a large metal object or surface. Locate the receiver as close as possible to the
area where the transmitter will be used. Ideally, position the receiver/antennas are within sight of the
transmitter. When using multiple systems, do not allow antennas to cross or touch each other.
Transmitter and Antenna Distance
Keep all transmitters at least 3 meters (10ft) away from the receivers and antennas for best operation. If
possible, mount the receive antennas 3 meters (10ft) above the stage so transmitters can not come too close.
