(1) About the data format

As shown in Fig. 2, there are 32 bits of data. When the

power is applied, a reset is applied to switch ports 1 to 4

off, but the reset is not applied to the other ports, so they

are unstable. For this reason, it is necessary to input the

data at least once while the set mute circuit is on.

∗ D18 : Surround matrix 1 control

D19 : Surround matrix 2 control

S Surround is on when the bit data is 0, and off when it

is 1.

S With regard to the port 1 to 4 outputs, when the power

is on, if no data is input the transistors for each output

are set to off. The outputs are on when the bit data is

1, and off when it is 0.

∗ Apply the following data for chip select and parity.
