The 1/4" input of the A-119 is a symmetrical high impedance input that will
amplify the hum noise of a cable with open end connected to the input. The
other side of the cable has to be connected to the sound source used for the
A-119 (i.e. do not leave it open). If the problems persist if a sound source
is connected the module has to be sent in for service/repair. In this case
please return the module to the dealer or representative where you purchased
the module.
