Analog Inputs
The TAS5424B EVM provides balanced input and the TAS5414B EVM provides unbalanced (single-
ended) inputs. The four RCA jacks on either EVM are provided for the audio input. The unbalanced inputs
have the shield of the RCA connected to ground. The balanced inputs have the plus (+) input on the
center pin of the RCA and the minus (–) input on the shield. The balanced ground can be connected to
the chassis or Power– (GND).
