Setting Up and Using the

Concert Series System

12.  Temporarily turn down the level of your mixer/amplifier system and turn off the power to 

your transmitter, leaving the CR277 on.  Then restore the previously set level of your mixer/ampli-

fier.  With the transmitter off, the receiver output should be totally silent—if it is, skip ahead to the 

next step.  If it isn’t (that is, if you hear some noise), you may need to adjust the CR277 front panel 

Squelch control. When the Squelch control is at its minimum setting, the Concert Series system 

always provides maximum range without dropout; however, depending upon the particular 

environment your system is used in, you may need to reduce that range somewhat in order to 

eliminate band noise when the transmitter is turned off.  To do so, use the provided screwdriver to 

rotate the Squelch control completely counterclockwise (to the “Min” position), then slowly turn 

it clockwise until the noise disappears.  If no noise is present at any position, leave it at its fully 

counterclockwise “Min” position (so as to have the greatest overall range available).

13.  When first setting up the  Concert Series system in a new environment, it’s always a good idea 

to do a walk-around in order to make sure that coverage is provided for your entire performance 

area.  Accordingly, turn down the level of your audio system and turn on both the transmitter and 

receiver.  Then, with the transmitter un-muted, restore the level of your audio system and while 

speaking or singing, walk through the entire area that will need to be covered.  Always try to 

minimize the distance between transmitter and receiver as much as possible so that the strongest 

possible signal is received from all planned transmission points.  In fixed installations such as A/V 

or corporate conference rooms or for extended range applications (where the transmitter and 

receiver are more than 150 feet apart), it may be desirable to angle the antennas differently from 

their vertical position or to install the receiver in the same room as the transmitters (and, if neces-

sary, to extend the wiring to remote audio equipment).

If you have followed all the steps above and are experiencing difficulties, contact your local dis-

tributor or, if purchased in the United States, call Samson Technical Support  (1-800-372-6766) 

between 9 AM and 5 PM EST.
