PCB PARTS LIST Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List. The mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure to use parts of identical designation. When ordering resistors, first convert resistance values into code form as shown in the following examples. Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%, and K=10%). Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5 6 1 4 7 3 R 5 0 1 R 0 5 6 2 1 NOTES: 560 Ω 47k Ω 0.5 Ω 1 Ω RD1/4PU J RD1/4PU J RN2H K RS1P K 56 x 10 1 47 x 10 3 R50 1R0 561 473 5.62k Ω RN1/4PC F 562 x 10 1 5621 Mark No. Description Part No. LIST OF ASSEMBLIES NSP 1..COMPLEX ASSY AWM7765 2..12V ASSY AWX8170 2..AMP OUT ASSY AWX8177 2..PRIMARY ASSY AWX8190 2..AMP KAWA ASSY AWX8223 2..D5V ASSY AWX8224 2..VIDEO ASSY AWX8225 2..AUDIO INPUT ASSY AWX8227 2..VHVL ASSY AWX8259 NSP 1..MOTHER ASSY AWM7884 2..DSP KAWA ASSY AWX8167 2..MOTHER ASSY AWX8423 NSP 1..FRONT ASSY AWM7780 2..FRONT ASSY AWX8199 2..POWER SW ASSY AWX8174 2..ENCODER ASSY AWX8175 2..FRONT-IN ASSY AWX8219 NSP 1..AMP MODULE 6CH AXQ7255 2..6CH AMP ASSY AWM7786 1..FM/AM TUNER MODULE AXQ7245 1..DSP ASSY AWX8241 Mark No. Description Part No. AFM/AM TUNER MODULE SEMICONDUCTORS IC201 BA1451F IC202 LC72131MD Q201, Q204, Q205 2SC2412K Q202 DTA124ES Q203 DTC124EK D201 1SS133 D202 MTZJ5.1C COILS AND FILTERS L201 FM DETECTOR COIL ATE7003 F202 CERAMIC FILTER ATF-107 F201 CERAMIC FILTER ATF-119 F203 AM CERAMIC FILTER ATF7026 CAPACITORS C206 CCSRCH100D50 C212, C213, C226, C233–C235 CCSRCH101J50 C240 CCSRCH101J50 C231, C232 CCSRCH150J50 C223 CEAT100M50 C229 CEAT101M10 C224 CEAT1R0M50 C227 CEAT220M25 C241 CEAT2R2M50 C243 CEAT330M16 C228 CEAT3R3M50 C237 CEAT470M10 C211 CEJQ1R0M50 C210 CEJQ470M16 C204, C238, C602 CKSRYB102K50 C101, C102, C208, C220, C239 CKSRYB103K50 C242, C601 CKSRYB103K50 C216, C217, C225 CKSRYB153K50 C201, C205, C209, C214, C230 CKSRYB223K50 C236, C603 CKSRYB223K50 C221 CKSRYB224K10 C202, C222 CKSRYB473K16 C215 CKSRYB681K50 RESISTORS R211 RD1/4PU221J R221 RD1/4PU222J R233 RD1/4PU391J R243 RS1/10S0R0J R103 RS1/10S331J R104 RS1/10S391J Other Resistors RS1/16S###J OTHERS CN201 13P CONNECTOR 52044-1345 BN201 TERMINAL 4-P AKA7003 (SHIELD CASE T) ANK7072 (SHIELD CASE B) ANK7073 X201 CRYSTAL RESONATOR ASS1093 (7.2MHz) FM FRONTEND AXF7003 AM RF TUNING BLOCK AXX7071 BVIDEO ASSY SEMICONDUCTORS IC2501 NJM2296M Q2501 2SA1515 Mark No. Description Part No. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com VSX-C302-S 74 1 2 3 4 1 2 3 4 C D F A B E Q2502 2SC3377 Q2505 DTA124EUA D2509-D2511 1SS355 D2501-D2504 DAN202K D2505,D2506 UDZS6.2B CAPACITORS C2505-C2507,C2517 CCSRCH221J50 C2513,C2514 CEAT470M10 C2501-C2504,C2511,C2512 CEAT470M25 C2518,C2524 CKSRYB103K50 C2519 CKSRYB104K25 RESISTORS R2514,R2515 RS2LMF181J Other Resistors RS1/16S###J OTHERS CN2501 19P CONNECTOR 52044-1945 JA2504 MINI JACK AKN7037 JA2505 REMOCON JACK RKN1026 JA2506 1P PIN JACK VKB1122 JA2501,JA2502 2P PIN JACK VKB1134 CAUDIO INPUT ASSY SEMICONDUCTORS >IC620, IC621 PROTECTOR(2.5A) AEK7014 IC701 NJU7312AM IC901 TC7WU04F IC702 UPC4570G2 D622–D625 1SR154-400 D701 DAN217 COILS AND FILTERS F620, F621 CHIP BEADS DTF1070 L901 CHIP SOLID INDUCTOR QTL1013 CAPACITORS C622 (1/100V) ACH1237 C701–C708, C725–C727 CCSRCH101J50 C731, C732 CCSRCH101J50 C709, C710 CCSRCH220J50 C908 CCSRCH470J50 C904 CCSRCH471J50 C723, C724 CEAT100M50 C620, C621 CEAT222M25 C737, C738 CEAT470M25 C729, C730 CEAT4R7M50 C711, C721, C722, C735, C736 CKSRYB103K50 C905, C906 CKSRYB103K50 C901, C902 CKSRYB104K25 C903, C909–C911 CKSRYB105K10 RESISTORS >R620 RD1/4MUF4R7J Other Resistors RS1/16S###J OTHERS 621 5P CABLE HOLDER 51048-0500 CN704 4P PIN JACK AKB7015 CN621 3P TOP POST B3B-EH J620 JUMPER WIRE 5P D20PYY0510E JA901, JA902 OPT.

Purposes Automatic detection of connected speakers and automatic selection of settings appropriate for the detected speakers allow you to easily play surround-sound without your making cumbersome speaker settings. 2. Speaker detection method Automatic detection of connected speakers starts 1120 ms after the power is turned on. • Detection of the center and surround speakers The microcomputer sends a detection signal and reads the logic of the response signal to judge whether the speaker is connected or not. The response signal is read at A/D input, and a voltage of 3 V or more is judged as no speaker connected. • Detection of the subwoofer The logic of the signal from the phono jack with a switch is read by the microcomputer to judge whether a speaker is connected or not. 3. Speaker settings According to the results of detection, speaker settings are made as shown below. Rules: The setting for the front speakers depends on whether a subwoofer is connected or not. If a subwoofer is connected, the setting for the front speakers is "small." Settings for other speakers are "small" or "not connected" depending on the results of detection. Settings for the rear surround speakers are in effect only when surround speakers are connected. 4 User's settings More detailed speaker settings can be made in Setup mode. Once the user's settings are made in Setup mode, those settings have priority. However, if the configuration of connected speakers changes, then the detection results become valid and have priority over the user's settings until new user's settings are made. 5 Detection circuit for the center speaker Satellite speakers may be connected. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com VSX-C302-S 83 5 6 7 8 5 6 7 8 C D F A B E 7.1.4 Circuit Description to XPROTECT µ-com AMP Assy R108 27k R101 (R104) 1k C101 (C102) 1/50 Q102 (Q104) Q101 (Q103) D101 (D102) D105 (D106) UDZS7.5B Q101 (Q103) C2 E2 B2 E2 C2 B2 C E B E C B Q102 (Q104) R102 (R105) 10k R103 (R106) 10k A B V+5D VD+5 VH+ (VP+15) VH– (VA–12) • In Normal mode, as Q101 (Q103) (E2, B2, C2) and Q102 (Q104) (E2, B2, C2) are on, the voltage at Point A is about 5 V. The voltage at Point B is therefore about the same. As Q101 (Q103) (E, C, B) is off, Q102 (Q104) (E, C, B) is also off. (1) When VH+(VP+15) is short-circuited to GND As the voltage at Point B becomes almost ground potential, and Q101 (Q103) (E, C, B) then Q102 (Q104) (E, C, B) are turned on, the level of XPROTECT becomes low. → The microcomputer detects the XPROTECT level and shuts the power to the unit off. (2) When VH–(VA–12) is short-circuited As the electric potential of VE at Q102 (Q104) (E2, C2, B2) becomes the same as that at VB, Q102 (Q104) (E2, C2, B2) is turned off. Following this, Q101 (Q103) (E2, B2, C2) is turned off, which changes the voltage at Points A and B to a value other than 5 V. Therefore, Q101 (Q103) (E, C, B) then Q102 (Q104) (E, C, B) are turned on, the level of XPROTECT becomes low. → The microcomputer detects the XPROTECT level and shuts the power to the unit off.

Then Q3651 (E2, B2, C2) is turned on, and the level of XPROTECT becomes low. → The microcomputer detects the XPROTECT level and shuts the power to the unit off. When FAN+ and FAN- are short-circuited, the electric potential at Point (A) becomes higher than GND level by the addition of the values at D3656 and D3657.
