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.
