Data Transmission of Fixed Equalizer Setting
• Faulty operation in the communication error occurrence.
Fixed equalizer setting premise no-change setting a fter setti ng is done once.
By this premise, A noise countermeasure circuit of the setting change isn’t built in.
Therefore, It has the possibility that noise i s made by communication error.
These countermeasures are taken by this IC as it is shown in next page.

Soft-Changing
This IC built in the Soft-changing circuit for reduce the step-noise of Fader when internal switch changing.
By this function, Switching noise of no-sig nal and so me signa l s can be reduced.
• SOFT-CHANGING 1
This is the circuit which changes gain smoothly at the setup time.
This function can work as follows,
(1 ) At the time of Soft-chan g ing ON.
(2) Slot15/D6=0
(3) After the last Soft-changing is completed.
For example, the movement when Fader is changed from 0dB to –6dB is shown in the right figure(ex.1).
After this IC receive the data of fader:-6dB , this circuit changes fader setting from 0dB to –6dB at a time.
Switching time is the ti me when it was set up with Soft-changing time.

• SOFT-CHANGING 2
This is the circuit which changes gain by 2dB step .
This function can work as follows,
(1 ) At the time of Soft-chan g ing ON.
(2) Slot15/D6=1
(3) After the last Soft-changing is completed.
For example, the movement when Fader is changed from 0dB to –6dBis shown in the right figure(ex.2).
After this IC receive the data of fader:-6dB,
0dB ” ⇒ -2dB ” ⇒ -4dB ” ⇒ -6dB ”
this circuit changes fader setting from 0dB to –6dB by 2dB step.
Switching time is the ti me when it was set up with Soft-changing time.
Total changing time is as the follo ws.
●Total changing time=Soft-changing time × the number of the step
In the case of the right figure, total changing time is 99mS. (33mS × 3 step s)
When Soft-changing time is long, step noise is more reduced. Because the step noise is has relations with Soft-
changing time. We recommend SOFT-CHANGING 2.
However, please confirm step noise by listening test, and judge it.
