USER MANUAL - PMA1020 PRECISION 2-WAY WIRELESS ACTIVE PA SYSTEM
Handheld Transmitter
The PMA1020 comes with a wireless handheld or beltpack transmitter (and an optional second one)
that syncs with the built-in RF receiver(s). To access the handheld microphone, open the storage com-
partment on the top of the PMA1020 by pushing down the compartment lid where indicated. To
close the compartment, simply press again until the compartment lid locks into place.
Always switch off the transmitter and keep it safely stored in the compartment when not in use.
GAIN control. This control determines the sensitivity of the microphone, which is preset from
factory to the optimum value for standard applications. If you need to modify this setting, turn
the control to the left to reduce the sensitivity or to the right to increase it.
RF switch. Use this switch to set the strength of the transmitter’s radio frequency signal. Set
to High for weak signals and Low for strong signals.
Transmitter IR window. This sensor serves to synchronize transmitter and receiver. For chan-
nel synchronization, unscrew the body of the microphone and align the infrared window of the
transmitter with the infrared window of the receiver

Battery compartment. The handheld transmitter uses two "AA" alkaline batteries (LR6, 1.5 V)
for an expected life of up to ten hours. To install or replace the batteries, unscrew the body of
the microphone and slide the batteries into position observing the polarity indicated. When the
BATTERY/ASC indicator
[55]
flashes red, replace the batteries immediately.
BATTERY/ASC indicator. This LED indicates whether the microphone is on and has enough
battery (green LED permanently lit) or if the batteries are too low (the LED flashes red), in
which case you should replace them immediately. Further, the LED flashes green whenever
Auto-Sync Channel is taking place.
ON/OFF switch. Switches the transmitter on and off. Make sure you switch the microphone off
when not in use to extend battery life.
Beltpack Transmitter
Antenna.
Power/Battery indicator. This LED illuminates green when the transmitter is on and has
enough battery to operate normally; otherwise, it lights up yellow when the battery is low. When
the LED flashes, it is indicative that infrared transmission is taking place.
Microphone INPUT. Use this mini-XLR plug to connect a dynamic microphone or a musical
instrument to the beltpack transmitter.
