5. GND terminal
1) Be sure to short-circuit each GND terminal of
pin 3, 8, 9 and 14 at the outside of the IC in use.
2) For each GND terminal, the one-point earth,
referenced to the GND connection point of
electrolytic capacitor between the supply ter-
minal and GND, is most effective for reduc-
ing the distortion. Even in the worst case,
ground pin 8, 9 of input GND separately from
all the other GND terminals.
3) Each GND terminal is not electrically short-circuited inside. Only pin 8 is connected with substrate.
4) Pin 9 is input signal GND. Connect only pin 9 with Pre-GND.
6. Cooling fin
1) The cooling fin is not connected with GND terminal by using Au wire. Only pin 8 is electrically connected
through substrate.
2) Always attach an outside heat sink to the cooling fin. The cooling fin must be fastened onto a chassis for use.
Otherwise, IC lead failure may occur.
3) Do not give the cooling fin any potential other than the GND potential. Otherwise, it may cause breakdown.
4) Connection of the cooling fin with GND can reduce the incoming noise hum. (It is unnecessary to connect
with GND in use, but connect with the power GND when the cooling fin is connected with GND)
7. Shock noise
1) STB on/off
No shock noise is released. However, the changeover switch of the standby terminal may make a slight
shock noise. In such a case, insert a capacitor of approx. 0.01
μ
F between the standby terminal and GND.
2) Mute on/off
No shock noise is released. Refer to the section on the mute function.
