8.  Turn on the power to your AH1 transmitter (using its Power on-off switch); the “Power/Battery” LED will flash if the battery is sufficiently 

strong (if it lights steadily, the battery has less than 2 hours of power remaining and should be replaced). If your system contains either a 

CR77  

receiver, one of the "A/B Receiver" LEDs will light, showing you whether the (left) "A" or (right) "B" receiver is currently being 

used.  The CR77 

meter will also indicate the strength of the incoming RF signal.

9.  Now it’s time to set the audio levels.  Turn on your connected amplifier and/or mixer but keep its volume all the way down. Make sure 

that the AH1 transmitter is unmuted (its Mute switch should be positioned away from the arrrow).  Then set the Volume, Level or AF Level 

knob on the receiver fully clockwise; this is unity gain.

10.  Speak or sing into your headset mic (or play the instrument to which the horn mic is attached) at a normal performance level while 

slowly raising the volume of your amplifier and/or mixer until the desired level is reached.  

11.  If you hear distortion at the desired volume level, first check to see whether the “Peak” LED on the receiver is lit .  If it is 

not 

lit, make sure 

that the gain structure of your audio system is correctly set (consult the owners manual of your mixer and/or amplifier for details).  If the 

“Peak” LED 

is 

lit, simply move the microphone further from your mouth.

12.  Conversely, if you hear a weak, noisy signal at the desired volume level, again make sure that the gain structure of your audio  system 

is correctly set (consult the owners manual of your mixer and/or amplifier for details) and that the Volume, Level or AF Level  control of the 

receiver is fully clockwise.  If it is and the signal coming from the receiver is still weak and/or noisy, simply position the microphone closer to 

your mouth.

13.  Temporarily turn down the level of your mixer/amplifier system and turn off the power to your transmitter, leaving the receiver on.  Then 

restore the previously set level of your mixer/amplifier.  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 receiver Squelch control.  When the Squelch 

control is at its minimum setting, the AirLine system always provides maximum range without dropout; however, depending upon the par-

ticular environment your system is used in, you may need to reduce that range somewhat in order to eliminate band noise when the AH1
