1. To use the AUTO CALIBRATION function for speaker output optimization, 

connect the CARIBRATION MIC, which is included in the package, to J201. The 
MTK IC(IC1101) will output the audio signal to the AMP circuit and the SPEAKER 
outputs the test audio sound. The connected MIC picks up this audio sound and 
A CAL MIC

A.CAL MIC audio signal will be input.

2. The PLUG_DET terminal  of the SYSTEM CONTROL(IC5002 65pin) detects the 

connection of the A.CAL MIC terminal(J201), and when the MIC is not connected 
an error indication will be displayed.

3. The A.CAL MIC audio signal is amplified by the LINE AMP(IC202), and then input 

to the SYSTEM CONTROL(IC5002 92pin) though the MIC AMP(IC203).

4. The SYSTEM CONTROL performs A/D conversions for the MIC level input signal 

inside the IC, and calculates the optimum speaker setting level.

5. While the MIC terminal is being used as the AUDIO IN_4 input terminal for 

portable audio sources, the PLUG_DET terminal and MONO_ST_DET terminal of 
the SYSTEM CONTROL(IC5002 65,90pin) perform MONO or STEREO detection 
of the input of the AUDIO IN 4

of the input of the AUDIO IN_4.

6. The analog audio signal will be output to the S-MASTER PROCESSOR(IC3001 

69pin) through the LINE AMP(IC202).

7. The S-MASTER PROCESSOR(IC3001) converts signals to digital, and outputs 

the digital audio signal to the AMP circuit of specified channel. After this step, the 
operation is as same as described in disc playback operation.(See 4-2).

1. The received signals are turned by control signals from the SYSTEM CONTROL.

2. FM signal input from antenna is converted to analog audio by the FM 

RECEIVER(IC101).

3

Analog audio signal is output to the S-MASTER PROCESSOR(IC3001 43pin)

3. Analog audio signal is output to the S MASTER PROCESSOR(IC3001 43pin).

4. The S-MASTER PROCESSOR(IC3001) converts signals into digital, and outputs 

the digital audio signal to the AMP circuit of designated channel. After this step, 
the operation is as same as described in disc playback operation.(See 4-2)

5. The analog signal input from the AUDIO IN terminal will be input to the S-

MASTER PROCESSOR(IC3001). After this step, the operation is as same as 4.

1. Optical audio output is input to the DIR(IC6001 1pin) from the OPTICAL 

RECEIVER(IC6002 2pin).

2. The DIR(IC6001) decodes optional audio signal, and then outputs serial audio 

data to the MTK IC(IC1101 52pin).

3. The digital audio signal input to the MTK IC will be output to AMP circuit as same 

as the disc playback signal.(See 4-1)

(Note)  If unable to output the optical audio signal from the TV when connecting the 

HDMI terminal of non-ARC-compliant TV.

•

Set the [AUDIO RETURN CNANNEL] of [HDMI SETUP] to [OFF] in configuration 
of the main unit.
