Hi Lonnie, We have not start to modify the schematics yet, and we plan to complete the schematics design is on 10/23. And No problem. We can provide you with the items you list as below then. Thanks. 1. Amp block schematics 2. Revision history(all block) Regards, Sean |

Dear Sean We provided DVT changing request. Please review then reply whether apply or not. Best regards Lonnie Kim |
|
|
Dear Sean We added changing Woofer connector and BT antenna points. Best regards Lonnie Kim |

Hi Lonnie, Got it. We will review it and let you know if we have any questions. Hi Tom and Fu-Chiang, Please read carefully the DVT changing request file provided by Lonnie, and provided your comment if there is any questions. Thanks, Regards, Sean |

Hi Lonnie, LED die needs to change the direction for 90 deg. May we know why does LED die need to change direction? Is it for light bar of RGB order or something else? Thank you. |

Hi, Lonnie For SOC board 1. Add FET at 24V power line for reduce standby power consumption <tom> This mean turn off 24V power during standby power. All function in this produce will power off, such as SOC/LAN/BT. Are you sure this need this design change ? For AMP board 1. J802 4P connector need to divided to 2 x 2P Connectors <tom> J802 is woofer speaker connector. Can this connector be selected by Fii ? Thanks ! |
|
|
Hi Tom, reply 0000978:0004734 For AMP board the Fii was selected JST connector for amp board. also DVT connector is can changed by Fii. so please check and let us know it is possible to divided to 2 x 2P Connectors and connector P/N ASAP. because this is related speaker cables. Thanks SON |

Dear Fu-chiang Young reply 0000978:0004733 We want to bright flatness, so we change direction. Please understand. Best regards Lonnie Kim |

Hi Sean Please HDMI connector move about 1.5 mm outward before DVT gerber out. as I attached request email. Thanks SON |

Hi, SH reply 0000978:0004738 I checked with two vendors, they don't have pitch 2.5mm/ 2x2p connector. Thanks ! |
|
|
Dear Tom reply 0000978:0004738 No, 2.5mm/2x2p. It is 2.5mm/1x2p(2P connector). It means divided current 1x4p for woofer connector. Best regards Lonnie Kim |

HI Tom Lee reply 0000978:0004820 Please refer to the speaker cable datasheet. the woofer connector will be apply JST EHR-2. so, please check and answer asap AMP board side, split J802 : 1x4p to 1x2p and 1x2p : B4B-EH(LF)(SN) x1pcs -> B2B-EH(LF)(SN) x2 pcs Thanks SON |

Hi, SH reply 0000978:0004830 We can change woofer speaker connector from 1x4pin to 1x2pin. For easy assembly issue, we plan to change all DIP connectors (J802,J803,J804,J812) from ST type to RA type. How about your opinion ? Attached are the datasheets and part number for you reference. 1x4p/2.5mm: S4B-EH (LF)(SN) => for Left / right side woofer and Mid. range speaker, page16 on datasheet 1x2p/2.5mm: S2B-EH (LF)(SN) => for woofer speaker, page16 on datasheet 1x2p/3.96mm: 51318-0023L-001 => for power cable |

Hi Tom Lee reply 0000978:0004841 ST type to RA type is good idea for easy assembly. I want to make sure that the connectors moving from Top to Bottom layer, is it right? before the confirmation, please check your mechanical engineer - The gap between the hestspreader amp top and amp PCBA is ONLY 4.3mm. - Make sure that these two parts do not touch. if touch these, it may make noise and vibration : I think FXN has 2 options. Let's decide on a good way. options 1. heat spreader amp top modify : cut off RA connector area. options 2. Lower position the height of the the amp pcba : heatspreader soc top boss modify Thanks SON amp_heatspreader amp top.jpg (160,074 bytes) |

Hi, SH reply 0000978:0004850 No, all Speaker connectors are at Top layer. For the 2 options, will reply you soon. Thanks ! |
|
|
Hi, SH reply 0000978:0004850 The gap between top layer of AMP board (components side) and heatspreader are 6mm. Because connector height of 1x4p RA type connector are 4.2mm, it's less than 6mm. So, there are not connectors touch heatspreader problem. thanks ! |

Dear Tom Please add to TP points attached file. Best regards Lonnie Kim |

The SWAN already entered the MP stage. There is no further action needed for this issue. So, we close this mantis issue. Thanks! |
