6. Make the physical cable connection between the AP1 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 AP1 completely counterclockwise, then slide its Power switch in the direction of the arrow to turn it on. The
"Power On" LED will light steadily green.
8. Turn on the power to the transmitter. The "TX / Peak" LED on the AP1 receiver should now light steadily green, indicating that it is receiv-
ing valid RF signal and is placed and positioned correctly.
9. 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 AP1 "TX/Peak" LED. If
the LED lights red (indicating a Peak condition) even with the AP1 Level control fully counterclockwise, engage the 15 dB pad on your
transmitter by sliding the switch in the direction of the arrow. If not, slowly turn the AP1 Level control clockwise to the point where the "TX/
Peak" LED occasionally blinks red during the very loudest passages, then back it off just slightly; this will ensure maximum signal to noise
ratio. Finally, raise the level of your amplifier and/or mixer until the desired volume is reached.
10. If you hear distortion or the AP1 "TX/Peak" LED lights red even with the 15 dB pad engaged and the Level control at minimum (fully
counterclockwise), reduce the output level of your instrument until the LED no longer lights red. 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
AP1 Level control is turned up. When using instruments with active or high level pickups, the Level control should normally be set in the
marked region.
11. Temporarily turn down the level of your amplifier or mixer and turn off the power to your transmitter, leaving the AP1 receiver on.
Then restore the previously set level of your amplifier or mixer. With the transmitter off, the receiver output should be totally silent; if it is,
skip ahead to the next step. If it isn't (that is, if you hear some noise), you may need to adjust the AP1 Squelch control. When the Squelch
