Data Input Format

(Data other than the following settings should not be sent)

By changing the D14 and D15 slot setting states, any of four input formats can be selected.

(However, each time the power is turned on, after sending the following MUTE release data, initial settings should be

made for the data of all four formats.)

Note 1) Using external surround ("D5d=1", "D13d=0")

→ SW41, 42 settings fixed at B, REC-C SW fixed at OFF

Using internal surround [1] ("D5d=0", "D13d=0")

→ SW41, 42 settings fixed at A, REC-B SW fixed at OFF,

volume input selector A setting fixed at A.

Note 2) The following settings are used to mute the output pin at power-on.

Input selector = ALL OFF, external surround mode setting, REC-A to C SW=OFF, second-stage main volume =-

∞

(and, when D14=D15=1 and D16=D17=0, by setting D3d=D5d=1, mute can be similarly set)

Note 3) This function is added in the M61510AFP

When using internal surround [2] ("D5d=0", "D13d=1")

→ SW41, 42 fixed at A,

REC-B/C SW fixed at OFF, volume input selector A setting fixed at B

It is the same as that of

M61510FP

*Regarding [1]/[2] when using internal surround

*Using internal surround [1] (same function as in existing model M61510FP)

In this mode only the internal surround function is used, and external circuitry is not used.

*Using internal surround [2] (function unique to M61510AFP, added to this IC)

In this mode the internal surround function is used, and in addition an external circuit is connected and used.

(However, because REC-C is fixed at OFF, use as the REC output is not possible.)
