... Note 3: An abnormal DC offset voltage is incurred when the input bias to the power IC is lost due to a leakage current from a coupling capacitor at the input or a short-circuit between the IN and adjacent lines.

... Pop Noise Suppression Since the TB2929HQ uses the AC-GND pin (pin 16) as the common input reference voltage pin for all amplifiers, the ratio of the input capacitance (C1) to the AC-to-GND capacitance (C6) should be 1:4. Also, if power is removed before C1 and C6 are completely charged, pop noise will be generated because of unbalanced DC currents ...
