KK Sir

做了 CDM9 PRo ,但是個 Clock 時常都唔 work, 手上剛好拿了 6j1 CDM 9 PRo module 的資料,發覺個 clock 是用 16.x mhz, 和我地用 11.X mhz 是不同的,請問那一個是正的?由於 KK sir 塊板的資料不全,無法在進一步改進,希望能指教。

Re: CDM 9 Pro Clock

Photo,

1. The length of the clock signal wire should be as short as possible.

2. The Frequency is depends on the SW. You can refer to the another model CD-Pro2, it is using SAA7324. The XTAL can be use 8.4672MHz to 33.8688MHz which depends on the SW setting.

3. You can take your CDP to me for checking why the TCXO is not work. All are welcome to you.

THX, KK

1. 個鐘時常俾你 supply 個的銀線玩死!下次請別在用那些銀!上次 Digital out 直接銲都唔得!條野太硬又易斷。個 socket 又接觸不良!是否又要銲?條 digital out TTL 對音影響好大,default 太衰聲,條銀線又咁,有甚麼線提議?

2. CDM 9 上的晶振是 16.9 mHz 的,現在用 11.x Mhz ,你話可以用 SW set, 是否須要 jumper 做 setting, 我是否可改 16.9 mhz ?

3. 我對大箱不太感冒,現在想改用其它箱,但因空間問題,只能用回 VFD 做顯示,請用 VFD 時,是否要在板提供 AC3V 和 AC 20V 才有顯示?

4. 想問問 digital output 的 buffer  多隻的 74CH04 和 26SL31 的聲音如何比較?

方唔方便我 call 你 discuss.....

Thank you....

Take it to me, I assemble to you. Free of charge, or you can buy a lunch for me.

2. CDM 9 上的晶振是 16.9 mHz 的,現在用 11.x Mhz ,你話可以用 SW set, 是否須要 jumper 做 setting, 我是否可改 16.9 mhz ?

NO. Need to change FW.

3. 我對大箱不太感冒,現在想改用其它箱,但因空間問題,只能用回 VFD 做顯示,請用 VFD 時,是否要在板提供 AC3V 和 AC 20V 才有顯示?

Yes, please let me know you need this transformer or not.


4. 想問問 digital output 的 buffer  多隻的 74CH04 和 26SL31 的聲音如何比較?

I will choose Series of // 04.

5. 方唔方便我 call 你 discuss.....
You can but after 7-Mar. Biz trip again.

Photo,

Pay attention on the additional transformer, the VFD display will cause you POOR sound.

Please note.

Wait me back.

KK @ NOT IN HK

Cannot fit the LCD into the new case, so no choice for using VFD display.....

I am not in HK now, please wait me back.

Mid-March will back to HK.

I understand you talk about VFD may emit high frequency. That is ok, I will seal the module with copper. But I can not fit the LCD module on the new case as the opening of the front panel is based on the VFD module size, I have no choice but to use the VFD.

I had installed the CDM 9 into a new case,it sound much better but there is constant reading problem on the 1st and 2nd track. Does anyone experience the same problem in reading tracks.... You comments is much appreciated.

Besides, I understand that the PCB board can be used for CD PRo2, I really want to try the CD Pro 2, what amendment do i need to make on it.... ?

I see a jumper is need and I understand the servo should be 5V and the motor is 9V, Should I make the jumper open as indicated on the board. There are some resistor which is not on the board, should I put it on the board and what value it should be  ?  R103, R104 R203 and R204. Would appreicate any one had experience in the CDPRo2 help. Thanks.

做了 CDM9 PRo ,但是個 Clock 時常都唔 work,
这个原因是晶振本身的原因不是电路的原因,具体原因可以加我的MSN:sican_2006@hotmail.com,这里说不太方便

手上剛好拿了 6j1 CDM 9 PRo module 的資料,發覺個 clock 是用 16.x mhz, 和我地用 11.X mhz 是不同的,請問那一個是正的?
这个频率用那个?主要看芯片,11.2896M你用16.9344M,或者16.9344M你用11.2896M都是不合适的,要一样频率的才行.

以上是个人愚见.
