3.1 Receiver Setup and Operation
A. Receiver Setup
1.Place the receiver and antennas where there is a clear
line of sight to the area where the transmitter will be
used. Rotate the antennas to separate them by 90 de--
grees. See Part 15 for more information.
2. Connect the power cord to the receiver. Turn the re--
ceiver on and confirm that it is ON by checking the
main display screen. The display will show the com--
pany logo, software revision level and then display
the main screen with the last channel set.
B. Manual Channel Change
1. From the main display screen press the MENU but--
ton once to display the edit screen.
2. Press SET and the group number will flash. The UP
and DOWN buttons allow you to scroll through the
18 factory groups and 2 user definable groups.
3. When the group you desire is displayed, press SET
to select that group and the Channel Number will
start flashing.
4. Scroll to the desired channel, press SET to select.
5. Pressing MENU anytime before pressing SET ne--
gates any changes made since the last SET.
6. Once the desired group and channel are displayed
(but not flashing) press MENU twice to return to the
main display screen.
C. Frequency Assignment (User Defined Groups Only)
1. With a User Group (19u or 20u) and channel se--
lected in step three, press SET until the Frequency
Number flashes.
2. Use UP/DOWN to scroll in 25 kHz steps to the de--
sired frequency. With the desired frequency dis--
played press SET. Hint: holding in the arrow key will
increase the speed of the scroll. Just release and
press again for fine control.
3. Repeat until all desired Channels in the user group
are assigned a frequency.
4. Press MENU twice to return to the main display
screen.
D. Advanced ClearScan: This feature automates the pro--
cess of finding a clear group of inter-modulation free
channels and the clearest channels within those
groups. From the main display screen push Menu twice
to go to the MENU Screen and press SET to select
ClearScan.
E. ClearScan
All: This function scans all of the groups (fac--
tory and user) and returns a list of groups ranked by the
number of free channels.
1. Once ClearScan All has run, the screen will display
the clearest group with the open channels in that
group. You can scroll through the other ranked groups
using UP/DOWN.
2. When you have the group you want, press SET to run
ClearScan on that group. The display will now show
the group with the Channels ranked by clearness and
the clearest channel will be flashing.
3. Press SET to select and the clearest channel will be
installed, display will return to the main display.
NOTE:
Groups 17 and 18 have 16 channels and are marked
with an N (17n). These groups require the transmitters
to be in the LOW transmit power setting to work to--
gether. After ClearScan All runs, the N groups will al--
ways be displayed after groups 1-18 and any user
defined groups no matter how many channels are
free. If you need to use more than 12 systems at one
time, scroll down to the N groups and use the clearest
group with Normal transmit power.
F. ClearScan Group: this function will scan the group cur--
rently selected, which is useful for multi-system setup.
1. Use ClearScan All on the first unit of a multi-system
installation to select the clearest group.
2. For each system added, leave all previously selected
channel transmitters on, using Step 3 select the cur--
rent group, select ClearScan Group and press SET.
3. The display will show the remaining clear channels in
the group with the clearest flashing.
4. Select the desired channel with UP/DOWN or simply
press SET for the clearest channel.
5. The channel will be selected and return to the main display.
6. Repeat until all systems are set up.
G. ClearScan Band: selects and ranks the clearest 16 fre--
quencies in the 24 MHz bandwidth regardless of groups,
channels or previous coordination. This feature is useful for
selecting one clear channel in a very busy RF environment.
1. From the Options screen, select ClearScan Band and
press SET.
2. This scan will run until SET is pressed again so it can be
used to evaluate a site over an hour, day or even a week.
3. To end scan, press SET, the program displays Group
21S with the clearest open frequencies in the band as--
signed channels (up to 16).
4. These frequencies will remain assigned to this group
until ClearScan Band is run again.
Caution: Unlike the factory assigned groups, the channels in
21S are not coordinated. If more than two channels from
group 21S are used, the combination must be walk tested
with all transmitters on before use.

H. Change Lock-Out: Protects settings by disabling the
SET button.
1. To engage lock-out press and hold the UP and
DOWN arrow keys together for 5 seconds, until the
padlock symbol appears.
2. The MENU button still allows different screens to be
displayed but no settings can be changed and
ClearScan will not run.
3. To reactivate the SET key, press and hold the UP and
DOWN keys again for 5 seconds until the padlock
symbol disappears.
I. Continue Set Up: make certain the mixer or amplifier in--
put used for the REV is muted or turned down to a mini--
mum level.
J. Plug an audio cable (not supplied) into the 3 pin XLR or
¼ inch output of the receiver.
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.
K. Voice or Guitar: The REV system guitar optimization
mode requires both the transmitter and receiver be
placed into guitar mode.
1. Press Menu twice to display the options screen, scroll
down to Audio Edit and press SET.
2. With the Audio Edit Screen displayed press SET until
Audio setting flashes.
3. Use UP/DOWN to select Voice or Guitar mode. The
default setting is Voice.
4. Make certain the bodypack transmitter is in the same
mode.
5. Now refer ahead to transmitter setup and return to
step 10 when that is completed.
6. With the transmitter on, speak into the microphone or
play the guitar. Turn up the level on the mixer or am--
plifier until you are able to hear the desired signal. If
no audio is present, repeat setup and refer to the
troubleshooting section.
L. Audio Output Level Adjustment: It may be necessary
to adjust the receiver output until the volume level from
the wireless system approximates the level of an equiva--
lent wired mic/instrument.
1. From the main display screen, press MENU twice to
display the menu screen, scroll down to Audio Edit
and press SET.
2. Press SET to step through Mic/Line, Balanced (XLR
Lvl) and Unbalanced Audio (HiZ Lvl).
3. Use the UP and DOWN to adjust output levels when
flashing. The default settings are Mic and -18dB on
the outputs.
4. Press SET a final time so nothing is flashing to save
the setting.
5. Press MENU to return to main screen.
M. Sound Check Screen: can be used to walk test the per--
formance area.
1. From the main display screen, press MENU twice to
display the options screen, scroll down to Sound
Check and press set. The sound check screen will be
displayed and it includes the following elements.
2. Peak Hold Audio Meter - allows you to set the trans--
mitter gain as high as possible for the application
which maximizes the signal to noise ratio. Sing, yell or
play the guitar at the loudest desired volume and ad--
just the gain so the meter peaks between 50 and 100.
3. Low Hold RF Meter will tell you if you have adequate
coverage in the performance area. If the RF level
drops below 10 on the meter during a walk of the
desired area, reposition the antennas, or change the
channel and retest.
4. Drop Counter - will tell you if you are exceeding the
range or may have some interference problems to
contend with. Ideally this count would be zero for the
desired performance area. If there are several
squelch breaks while walking the area, adjust and
check the antennas and re-walk.
5. Dropout Tone - Press the UP button and the speaker
symbol will change. Now when the receiver incre--
ments the dropout counter, it will also send a 1 kHz
audio tone out the output so you can hear where on
the stage the drop occurs. Press DOWN to turn off
the tone. The tone will also deactivate when you re--
turn to the main display.
6. Left and Right Antenna Check - Press and hold the
SET button until the screen changes to two large me--
ters marked L and R. This screen is used to check the
continuity of the left and right antennas. If the RF lev--
els are not approximately the same, check connec--
tions. Press SET to return to Sound Check Screen.
N. Squelch Adjustment - The squelch setting can be used
to maximize range or immunity to noise.
1. Turn the transmitter off and from the receiver Options
screen select Squelch and press SET.
2. The current squelch setting will be displayed, the set--
ting will flash and (the tone coded portion of the
squelch is turned off in set mode to allow you to no--
tice any changes in the amplitude squelch setting).
3. Adjust the squelch using the UP/DOWN keys and
walk test the unit. Maximum squelch (15) maximizes
noise immunity but limits the range. Minimum squelch
(1) will maximize the range but may allow noise at the
end of range.
4. Repeat until desired range coverage is acceptable
with the maximum possible squelch.

Headphone Operation
1. With the transmitters and receivers setup and operat--
ing, plug stereo headphones into the ¼ inch jack on the
front panel.
2. The Selected Receiver LED will indicate receiver 1 is
being monitored. Press the Receiver Select button once
to change from Receiver 1 to 2.
3. Press the Receiver Select button once more and both
indicator LEDs will light. You can now listen to both re--
ceivers. NOTE: if both receivers are set to the same
channel, the volume will double.
4. Pressing the Select button once more cycles back to
Receiver 1.
Antenna Connections
1. Install the two ½ wave antennas to the "antenna in"
jacks on the rear panel.
NOTE: The two ½ wave antennas included with the REV
can be remote mounted. For an additional 5dB gain use the
LPA500 log periodic directional antenna.
2. The REV-DUAL is equipped with a left and right an--
tenna output jack. These jacks can be used to connect
up to 3 REV-DUAL (6 receivers) to two antennas with--
out any additional equipment. DO NOT remove
"dummy" loads unless connecting to another receiver.
3. Figure 3 shows the connection diagram for 3
REV-DUAL units.
4. Up to 12 REV-DUAL units can be operated with just two
antennas with the optional APD4+ antenna distribution
unit (see Figure 4).

12 Volt Power On "Antenna In" Jacks
To power in line antenna amplifiers, 12 volt power is available
on the center pin of the antenna in jacks. This power is dis--
abled when the REV leaves the factory but may be turned on
by the installer.
To turn on the 12 volts, first take off the cover of the radio by
removing 14 screws. There is a 2 pin "header" and a "jumper'
behind the "XLR" audio connector on each of the two large
printed circuit boards. See Figure 5. The jumper is installed
on one pin of the header at the factory. To turn on power, un--
plug the jumper and install it on both pins of the header.
CAUTION: Do not attach antennas and splitters with a DC
short circuit to the antenna in jacks when the power is turned
on. Damage could result to the splitter or receiver.
The following antennas and accessories may be used with
power on:
FA-1, CLA-X, APD4+, APD4-1+, UAA-50
The following antennas and accessories may be used with
the power off:
