4. ClearScan: This feature automates the process of finding a clear channel.
a. To scan for the clearest channel in a group, press and hold until CLEARSCAN
appears in the display, then release the button.
b. When the scan is complete, the display will show the clearest available channel.
c. Use the SYNC button to transfer the new channel as in step 3.
5. During set up make sure the mixer or amplifier input used for the R300 is muted or turned down
to a minimum level.
6. Plug an audio cable (not supplied) into the 3 pin XLR or ¼-inch TRS output of the R300.
Note: The XLR connector is the preferred connection since the output is balanced and will be
more immune to noise for longer runs of cable although either can be used with good
results. Set the balanced output level on the back panel to 12 o’clock (midway in the
range) to start and adjust later if necessary. If the ¼-inch unbalanced output is used, start
with adjustment switch in the -10dB setting.

7. With the transmitter on, speak into the microphone or play the guitar. Turn up the level on the
mixer or amplifier until you are able to hear the desired signal. If no audio is present, repeat
setup and refer to the troubleshooting section.
Note: It may be necessary to adjust the receiver output until the volume level from the wireless
system approximates the level of an equivalent wired microphone/instrument.
8. DISPLAY The main display can be adjusted to display the Channel number or the Frequency.
Note: At any time the item not selected for the main display can be shown for 5 seconds by

10. Squelch Adjustment – The squelch setting can be used to maximize range or immunity to noise.
a. Turn the transmitter off.
b. On the receiver, press and hold the SET button until DISPLY shows in the display.
c. On the receiver, press two times to display SQELCH.
d. On the receiver, press SET and the squelch setting in the middle right of the screen (SQ
10dB) will flash.
e. On the receiver, press to decrease the squelch setting or to increase it.
f. On the receiver, press SET to enter the new setting and return to the main screen.
g. Turn on the transmitter and walk test the unit. Maximum squelch (50dB) maximizes noise immu-
nity but limits the range. Minimum squelch (5dB) will maximize the range but allow more noise
to break through the squelch. Never leave the squelch set to 0dB except for testing, white
noise will be constantly present on the audio outputs.
h. Repeat to fine tune receiver squelch to the desired setting.

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
