M61510AFP
Sound Controller for Quality/Sound Field Control,
with Built-in Surround Sound
REJ03F0013-0100Z
Rev.1.00
Aug.07.2003
Description
The M61510AFP is a digital sound controller IC which is ideal for home audio applications. M61510AFP includes
five-input selector, input volume control, surround sound (effect switchable in three stages), tone control (3 bands),
loudness, and two-channel master volume control, all controllable via serial data. The M61510AFP can be interfaced
with external circuits even when using the internal surround sound. And a common data format (software-compatible)
facilitates M61510AFP substitution.

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
*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.)

Explanation of Functions
(1) Main volume
This IC includes two independent low-distortion, low-noise electronic volume systems. The attenuation can be set from
0 dB to -∞ dB in 1 dB steps.
Also, the attenuation can be set between 0 and -16 dB for the first stage, and between 0 and -64 dB for the second stage,
and both can be controlled independently.

(2) Input selector, input volume
Two channels of 5-input selectors, and two channels of input volume controls for input trimmers, are incorporated. The
D and E inputs of the input selectors can select either 0 dB or -8 dB input levels for an input resistance of 12 kΩ using
the ATT switch. The input volume can be set between 0 and -14 dB in 2 dB steps.

(4) Vocal cut equivalent circuit diagram
This IC incorporates a circuit which uses a tone control midrange circuit to lower the midrange gain, to easily realize a
vocal cut function.
However, when the vocal cut function is on, the tone control midrange cannot be used.
