Setting Up and Using the
Micro 32 System
6. To check the battery strength, turn on the power to the T32 or H32 transmitter (using its
Power on-off switch). The multifunction LED will light green if the battery is sufficiently
strong. Once you’ve established that the installed battery has sufficient power, use the
Power on-off switch to turn the transmitter off again.
7. Make the physical cable connection between the output of your M32 receiver and the
audio input of your video camera or audio amplifier or mixer, being careful to set the Audio
Output Level switch so that the signal is strong but not distorting. Normally, it should be set
to the “-30” position when connecting to a mic-level input and to the “-20” or “-10” position
when connecting to a line-level input. If required, both the balanced and unbalanced
outputs can be used simultaneously. Leave your amplifier (and/or mixer) off at this time.
8. Next, select the Group and Channel for your transmitters and receivers. When two or
more transmitters and receivers are being used at the same location, all devices must be
set to the same Group (though each transmitter/receiver pair must use its own Channel) or
intermodulation noise may occur. With the power to your transmitter off, set the M32 Meter
switch to the left “RF” position, then use the supplied plastic screwdriver to set the M32
Group and Channel trimpots to an available channel within a Group. (Refer to Appendix B
on page 17 in this manual for a complete channel plan.) Next, turn on the transmitter and
set it to the same Group and Channel (its multifunction LED will blink whenever an
unavailable Channel within a Group is selected). One or more segments in the M32 meter
should then light. If the “HIGH” segment lights, the M32 is receiving an optimally strong
RF signal. If the “LOW” segment lights (indicating a relatively weak RF signal), try a
different Channel within the Group or a different Group/Channel altogether—you will find
that some have stronger signals than others. Always pick the Channel that has the
strongest signal.
9. Next, it’s time to set the audio gain structure. Turn on your connected amplifier and/or
mixer but keep its volume all the way down. Make sure that your transmitter is unmuted by
setting its Audio switch to “On.” If you are using the H32 transmitter or if you are using the
T32 transmitter with a connected lavalier microphone or headset, speak or sing into the mic
at a normal performance level while slowly raising the volume of your amplifier/mixer until
the desired level is reached. If you are using the T32 transmitter with a connected instru-
ment, play the instrument at normal performance level while slowly raising the volume of
your amplifier/mixer until the desired level is reached. If you are using a lavalier micro-
phone, correct placement is critical to sound quality.
We recommend that you position it as shown in the
illustration on the right—as close to your mouth as
possible but off to one side (to minimize nasality) and
unobstructed by clothing. Bear in mind also that
omnidirectional microphones (mics which pick up
signal from all directions) are more prone to feedback
problems than unidirectional (cardioid or supercar-
dioid) ones; in general, you can avoid feedback by
taking care not to use any microphone directly in front
of a PA speaker (if this is unavoidable, you can try
using an equalizer to attenuate those high frequencies
which are causing the feedback “squealing”).
