Be careful of looped connections
fig.loop.e
If the UA-20 is connected as shown above to a device that outputs (“thru-s”) the input 
audio (such as a cassette player that is in recording mode), turning on the 
Input 
monitor switch
 will cause the sound to loop between the UA-20 and the other device, 
causing oscillation and producing an unexpectedly high volume. Be aware that such 
connections may cause the system to malfunction, or your speakers to be damaged.
