MOON AIR Analog FM Tuner 

 

Front Panel Controls   (continued)

 

 

The “Stand by/On” button disengages the output section from the rest of the AIR’s circuitry and turns 
off the digital display. However, when in “Stand by” mode all audio circuitry remains powered up to 
help maintain optimal performance.  When switching back from “Standy by” to the “on” mode, all prior 
settings, including the tuned FM radio station’s frequency, will be restored from the previous listening 
session.  The blue pilot LED will not be illuminated when the AIR is in “Stand by” mode. 
 
The “Mute” button, when activated, eliminates signal noise between FM stations; When the signal 
strength falls below the mute threshold, there will be no audible output from the tuner.  This function 
is highly recommended when changing/scanning stations, however, once you have selected a station, 
it is recommended that you turn off the “Mute” function by simply pressing the button again.  The 
“Mute” indicator LED in the display window will illuminate when this function is active. 
 
The “Mono” button alternates the AIR between stereo and mono output.  Most FM radio stations 
broadcast in stereo, and to achieve the best sound reproduction, you should operate the AIR in stereo 
mode (the default setting).  The “Stereo” signal indicator LED in the display window will confirm that 
the station you are listening to is broadcasting in stereo.  In the event that a particular FM station has 
very noisy reception (ie. excessive background noise), it might be worthwhile to switch to the mono 
mode by simply pressing the “Mono” button.  At the expense of stereo separation, the mono setting 
will capture less than half of the noise typically captured in stereo mode.  When activated, the “Mono” 
indicator LED in the display window will illuminate and the “Stereo” indicator LED will turn off.  Pressing 
the “Mono” button again will return the AIR to stereo mode. 
 
The “BW 1/2” button allows you to select either a wide (BW 1) or narrow (BW 2) bandwidth setting for 
the Intermediate Frequency section of the tuner circuit.  The wide setting is recommended when 
adjacent channel interference is not an issue.  The narrow setting is preferable when adjacent channel 
interference is a factor; this setting has less high frequency extension, but is less sensitive to noise and 
interference from nearby stations.  You should choose the bandwidth setting which best suits your 
specific setup.  The default setting is “BW 1”.  When “BW 2” is selected, the “BW2” indicator LED in the 
display window will illuminate. 
 
The “Tuning” dial can be rotated either clockwise or counter-clockwise to select the frequency of the 
radio station you wish to listen to.  The three (3) LED array center tuning indicator located in the upper 
right of the display window should be used as a guide to achieve a center-tuned position; When the 
left LED illuminates, gently rotate the ‘Tuning” dial clockwise; When the right LED illuminates, gently 
rotate the dial counter-clockwise. You’re precisely tuned into a station when the center LED illuminates.  
Now you’re ready to fine tune the selected station using the vertical “Level” bar graph LED array, 
located on the right side of the display window; The  objective  is  to  maximize  signal  strength  and 
minimize/eliminate multipath.  This may require a very slight deviation from the precise center tuned 
position;  it may be necessary to sacrifice a higher signal strength to help eliminate multipath.
