Setting Up and Using the

Micro 32 System

camera.  If not, physically place the M32 in the position in which it will be used.  Next, with
the transmitter unmuted, walk through the entire area that will need to be covered while
speaking, singing, or playing your instrument.  As you do so, you will find that the orange
“A” and “B” LEDs on the M32 occasionally switch on or off, always showing you which
antenna is receiving the stronger signal.  The basic rule of thumb for successful wireless
installations is to always try to minimize the distance between transmitter and receiver as
much as possible and also to try to maintain “line of sight” between the two (so that the
person using the transmitter can see the receiver antennas).  You may also be able to
improve RF reception by relocating the receiver or repositioning one or both of the receiver
antennas.

13.  Temporarily turn down the level of your mixer/amplifier system and turn off the power
to your transmitter, leaving the M32 on.  Then restore the previously set level of your
mixer/amplifier.  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 M32 Squelch level control.  When the Squelch level control is at its minimum
setting, the Micro 32 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 level 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 counterclock-
wise “Min” position (so as to have the greatest overall range available).

If you have followed all the steps above and are experiencing difficulties, contact your
local distributor or, if purchased in the United States, call Samson Technical Support
(1-800-372-6766) between 9 AM and 5 PM EST.
