DEFINITION
Classification: 330/148
(under the class definition) Subject matter wherein at least two separate signal output circuits are coupled from the output electrode or element of the signal amplifying device, for coupling to separate load devices.
(1) Note. Where at least two of the signal output circuits each contain a signal amplifying device for amplifying the signal, classification is not herein but with plural signal
amplifier channels.
(2) Note. Any one or more of the separate signal output circuits may be switched selectively; operation need not be simultaneous for classification in this subclass.
(3) Note. A balanced circuit is treated as a single load in this class. See definition and notes for subclass 117 above.
