QuickStart
7. Now to set the channel, press and hold the
EDIT control until the display shows the
group number with three asterisks. Next,
the AR300 will display the selected Channel
number and then the IR SET will begin.
8. Once you see the IR SET flashing in the
LCD, hold the AL300 transmitter, with the
IR window facing the front of the AR300,
approximately 6 inches away from the
receiver and turn the AL300 power switch
on. The AR300 will transmit the channel
number to AL300 over infrared light and
you will see the Absolute Channel number
in the transmitter LCD.
8. Turn on the connected amplifier or
mixer but keep its volume all the way down. Se Begin speaking or singing at a
normal performance level while observing the AF Meter. If the AF Meter reads
above “0” (indicating a Peak condition) even with the AR300 Level control fully
counterclockwise, engage the 15 dB pad on the transmitter. If not, slowly adjust
the GAIN inside the AL300 to the point where the AF Meter occasionally reads “0”
during the very loudest passages, then back it off just slightly. Finally, raise the
level of your connected amplifier and/or mixer until the desired volume is reached.
9. Do a walkaround through the intended area of coverage while observing the
receiver’s RF Meter; it should continue to read about “75%”, indicating sufficient RF
reception in all areas of coverage. If not, reposition the AR300 or its antennas as
necessary.
10. If you hear any spurious noise from the receiver output when the transmitter
is turned off, use the supplied plastic screwdriver to adjust the AR300 Squelch
control, slowly turning it clockwise to the point at which the noise disappears.
