6. Make the physical cable connection between the AR300 output jack and an audio
input of your amplifier or mixer. Leave your amplifier or mixer 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
control switches facing you, approximately 6 inches away from the receiver and
turn the AG300 power switch on. The AR300 will transmit the channel number to
AG300 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 amplifier and/or mixer but keep
its volume all the way down. Set the output level of your electric guitar or bass
to maximum and begin playing it 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, engage the 15 dB pad on your
transmitter by sliding the switch in the direction of the arrow. (In general, if you
have single coil pick-ups, you’ll probably want set the PAD to “OFF”. If you have
supper hot humbuckers, you’ll probably want to switch the PAD on.) If the AF Meter
bars are not all lit, slowly turn the AG300’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 amplifier and/or mixer until the desired
volume is reached.
12. If you hear distortion or the AR300 AF Meter is reaching “0” with the 15 dB pad
engaged and the TX Gain control at minimum (fully counterclockwise), reduce the
output level of your instrument until AF Meter is reading less than “0”. Conversely,
if you hear a weak, noisy signal at the desired volume level, make sure that your
instrument is set to maximum output level, that the 15 dB pad is not engaged, and
that the AG300 Gain control is turned up.
