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 four frequency bands, A, B, C 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 groups in the back of this 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
receiver, set the transmitter to that clear channel and leave it on. Then scan the second unit receiver for
another clear channel. If 3 or more systems in the same frequency band are used in the same room, put
all of the channels in the same group as indicated by the channel groups on page 28-31.

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 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 receiver antennas 3 meters (10ft) above the stage so transmitters can not come too close.

FREQUENTLY ASKED QUESTIONS

Frequently Asked Questions

Q: How can I make sure my R300 system’s frequency band will work in my location?

A: If you will be using your system in the USA, you can check R300 compatibility in your location by using the frequency band
selector located at http://www.electrovoice.com/frequencyselector. If you are outside of the USA, please contact your local
Electro-Voice dealer or technical support center.

Q: Are there any web-based materials or how-to’s available which will help me understand my R300 system?

A: R300 how-to videos are posted at http://www.electrovoice.com/evtv.php?category=knowledge

Q: How many R300 systems can I operate at the same time?

A: The number of R300 systems you can operate simultaneously is completely dependent on your local RF (radio frequency)
conditions. Under ideal RF conditions (meaning there are no other sources of RF operating within or near your system’s
bandwidth), the maximum number of simultaneous R300 system within one tuning bandwidth is limited to 8 channels within
ONE channel group. However, local television broadcasts or other wireless systems operating within your system’s tuning
bandwidth will reduce that number.

Q: Can I mix frequencies from different groups?

A: No. Multi-channel R300 systems in the same bandwidth (A, B, C, or E) must operate within the same channel group.
Only frequencies within the same group are inter-modulation free. Frequencies from different groups may interfere with one
another.

Q: Can I use R300 systems from different bands at the same time?

A: Yes. Mixing systems from different bands is possible as long as you follow the group coordination guidelines of each band.

Frequently Asked Questions

Q: Why did I suddenly begin getting interference? During sound check, everything was fine – but after the show began, I
started getting interference.

A: Another radio system that wasn’t on during sound check began transmitting on, or near your system’s frequency. If this
happens, ClearScan you system again to find a new, clear frequency.

Q: I’ve hear the term line-or-sight. What does that mean?

A: In a wireless microphone system, line-of-sight means that optimal performance occurs within one room, with no walls or
structural barriers between the transmitter and receiver antennas. Any wall or enclosure the transmitted signal must pass
through will diminish the transmitted signal strength at the receiver. Your receiver antennas should be in the room your
transmitter is operating within and out in the open, unobstructed by walls or enclosures.

Q: Can I move the receiver antennas that came with my R300 system to another location?

A: Only with the appropriate hardware. And only to the appropriate location. The flexible ½-wave dipole antennas which
came with your system only function when connected directly to your receiver’s antenna jacks, or when front-mounted in a
19-inch audio rack with the R300 antenna mounting hardware listed in the system accessories table in this guide. Moving
these antennas anywhere outside of the rack (such as on a stand or mounted to a wall) will not work. If your needs include the
remote mounting of receiver antennas, you must use antennas designed for that application, such as the LPA500 log periodic
antenna.

FREQUENTLY ASKED QUESTIONS

Frequently Asked Questions

Q: Where is the EZsync port on the R300 handheld transmitter?

A: The EZsync port is located under the handheld transmitter’s removable battery cover. Just as you would do in order to
change the batteries, you must loosen the battery cover to expose the EZsync port and aim the port directly at the receiver’s
EZsync port during the syncing operation.

Q: Sometimes I can’t get EZsync to work properly. Am I doing something wrong?

A: EZsync uses an infrared beam of light to sync transmitter to receiver. Extremely bright or fluorescent light can interfere
with the sync signal. If you experience difficulties with EZsync, shade the ports from extremely bright light sources during the
syncing operation.
