Feedback Information
5
What causes feedback?
Feedback is a ringing, howling, or shrill sound that is self-
generated by the sound system. It is the result of sound from
the speakers being picked up by the microphone and then
re
-
amplified by the system. This can form a self-sustaining
loop that can damage the sound system if allowed to continue.
How to prevent feedback
ALWAYS STAND BEHIND THE SPEAKER
WHEN USING A MICROPHONE!
CAUTION: Feedback can damage your equipment and may be
hazardous to your hearing. To avoid feedback, always make
sure volume controls are at minimum before turning unit on.
If feedback occurs, immediately reduce the volume.

Wireless Operation
Setting up the wireless system
Checking the Frequency Code:
Before proceeding, you must first verify that the wireless
frequency of your transmitter matches the frequency of the
receiver installed in your Anchor sound system.
1. The control panel of the sound system should have
the following label:
2. The frequency code must match the code found on
the transmitter as described below:
HANDHELD: Unscrew the battery compartment
cover on lower end of the microphone. Remove the
battery (if installed) and check code on the label.
BODY-PACK: Check the code on the label located
behind the belt clip.
3. If the frequency codes don’t match, locate the correct
transmitter whose code matches the sound system.
About the transmitter battery gauge/indicator
Assuming a battery is installed in the transmitter, you can
estimate the remaining operating time by sliding the power
switch to the PWR position (first turn the sound system off,
or set the transmitter mute switch to the MUTE position).

Setting up the Liberty Xtreme sound system
Positioning of the speaker is perhaps the most important
consideration when setting up a sound system. You should
survey the location prior to the activity and observe the
seating arrangement and area of coverage.
Basic principles of sound system set up:
•Position your sound system in front of the audience
and ahead of the microphone.
• Elevate the sound system so the sound projects over
the front listeners. This permits sound to reach the
listeners in the rear without overpowering those in
front. The Liberty is easily and safely elevated above
the audience by using Anchor’s SS-450 speaker stand.
•For long and narrow seating arrangements, position
one sound system in front and off to one side of the
listeners. Then position a second sound system mid-
way back on the same side of the audience. Direct the
speakers diagonally across the audience (see notes
regarding daisy-chaining below).
• Daisy Chain operation: There may be times when the
crowd size requires more than one sound system, or
when part of the audience is in a separate listening
area. To use multiple Liberty Xtreme systems, connect
a shielded mic cable between the Line Output of the
primary sound system to the Balanced Line Input of
Set-Up
sound system
sound systemsound system
Keep in mind,
the best sound
system set-up is
when the
audience is not
conscious of a
sound system
being used.

Speech Project Switch
The speech project switch allows the user to customize the
sound output of the Liberty Xtreme for a particular
application:
Standard setting (button out):
Liberty Xtreme provides flat, full-range frequency response
for music/singing or indoor vocal applications.
Speech Project setting (button in):
Frequencies in the vocal range (800Hz-12KHz) are boosted
for added clarity and efficient projection. Use for outdoor
functions, large crowds and speech applications.
12 Volt DC Output
The DC output jack is used to power
auxiliary equipment such as an outboard
wireless receiver or Anchor’s Mini-Mix.
It’s rated output is 12 volts DC, 300 ma
maximum.
Using the cassette tape player
The cassette player features auto reverse for continuous
playback. The audio signal is fed directly into the mixing bus
so the sound can be mixed with other inputs of the Liberty.
Note: Use only high-quality tapes, and periodically clean the tape
head with a cleaning kit.
Operation Set-Up
the second system. Set the volume on the second
system, and thereafter the volume of the primary
Liberty Xtreme will control both units.
Setting up difficult rooms
Reverberant rooms—those with acoustically-reflective
surfaces like glass or concrete (such as a gymnasium), can be
troublesome when using a sound system. Proper care must
be used during setup to minimize feedback, which is caused
by the microphone ‘hearing’ the sound reflected back from
the walls, floors and ceilings.
Te c hniques to reduce feedback in difficult rooms:
•The best microphones to use in feedback-prone rooms
are handheld, CollarMic
™
or headset boom types. They
allow the mic element to be close to the mouth so the
system ‘sees’ more of the user’s voice and less of the
room. The volume control can be turned down while
still maintaining an adequate sound level—another
important factor in reducing feedback.
•Orienting the speakers directly at the crowd and away
from the walls (and the user, or course) will help
reduce feedback. Experimentation may be necessary.

Operation
Line Input
The unbalanced line input is used for playback of a tape or
CD player, musical instrument, VCR or similar line-level
source. It may be combined with the other inputs for a
composite output.
N
ote:
All audio connections must be made with shielded cable
to avoid hum, buzzing or radio interference.
Mic Input
The balanced, low impedance XLR microphone input is for
use with a balanced microphone to help prevent hum or
interference when using long cables. It has phantom power
for use with condenser-type microphones.
Balanced Input
Liberty Xtreme is equipped with a balanced XLR input jack
that can be set to allow microphone or line level sources, with
or without phantom power (15 volts DC).
A balanced microphone (Lo-Z) is preferred for use with long
cables to minimize hum and interference. Phantom power is
required when using mics with a condenser element; in all
other cases the phantom power switch should be set to OFF.
Anchor CD Input
The Anchor CD input provides an audio and power
connection for the CD-1 CD player accessory.
Line Output
The line output provides a balanced, composite signal of
the inputs being used. Use the line output to record your
presentation, or to “daisy chain” another powered sound
system to the Liberty Xtreme for greater crowd coverage.
Accessory Outlet
Use the Xtreme 5000’s accessory outlet to supply AC power
to an additional sound system or accessory. Anchor’s
PWRADPTR or PWRCORD cables allow easy connection
when running extension cables.
