2. Muting
(1) Audio muting This IC is possible to make audio muting operation by using 11 pin muting terminal. In Fig.3, the equivalent circuit in the muting circuit section is shown. By means of reducing the voltage of 11 pin down to 2.8 V or less in Fig.3, Q1 is turned ON and the base voltage of Q2 in the differential circuit fabricated with Q2 and Q3. Therefore, with the voltage reduction of 11 pin, the input circuits of dummy of input terminal and that in the doted line operate and cut-off the input signal. After muting, the bias circuit continues 1st operation and the power supply current of quiescent time. 8 pin, the capacitor terminal for reducing the pop noise can reduce the pop noise through making the time constant longer by means of inserting the capacitor externary. In the care this terminal is not used, short 8 pin with 11 pin. The voltage of 11 pin set up to 4 V or more. IC internal muting at VCC OFF When VCC = 8 V or less at VCC off, the detection circuit at VCC off is operated. And the base voltage of Q1 is reduced and the muting operation is mode.

3. Precaution for 4 W load resistance use
Internal output current detection and protection circuit protect the IC from the influence of unusual excess current. And this function causes the interrupted sound in case of excess input voltage with VCC higher than recommended supply voltage (24V). Therefore, the power supply regulation must be fully investigated so as not to make the VCC be high than recommendation supply voltage (24V).
Cautions
This IC is not proof enough against a strong E-M field by CRT which may cause malfunction such as leak. Please set the IC keeping the distance from CRT.
