Operation Manual

6. Make the physical cable connection between the AR300 output jack and an audio
input of your mixer. Leave your mixer and power amplifier off at this time.
7. Turn the Level knob on the AR300 completely counterclockwise, then set its Power
switch up to turn it on. The LCD display light will illuminate.
8. Now to set the channel, press and hold the EDIT control until the display reads CH
SCAN. Next, the AR300 will automatically find the clearest channel and you will see
it in the Channel number of the display just before the IR SET will begin.
9. Once you see the IR SET flashing in the LCD display, hold the transmitter, with the
bottom facing towards the AR300, approximately 6 inches away from the receiver
and turn the AX300 power switch on. The AR300 will transmit the channel number
to AX300 over infrared light and you will see the corresponding absolute channel
number in the transmitter LCD.
10. The RF Meter on the AR300 receiver should now be active, indicating that it is
receiving valid RF signal and is placed and positioned correctly.
11. Now it’s time to set the audio levels. Turn on your mixer and/or amplifier but
keep its volume all the way down. Plug the AX300 into the included Samson Q7
or any dynamic microphone. Begin speaking or singing at a normal performance
level while observing the AR300 AF Meter. If all the bars are lit, indicating a Peak
condition, even with the AR300 Level control fully counterclockwise, turn the
Gain control down. If the AF Meter bars are showing a weak level, slowly turn the
AX300’s Gain control clockwise to the point where the AF Meter reaches ‘0” during
the very loudest passages, then back it off just slightly; this will ensure maximum
signal to noise ratio. Now, raise the Level on the AR300. Finally, raise the level of
your mixer and/or amplifier until the desired volume is reached.
