Shigaclone MKII Black - The builders Thread

[iTiberius]

Hi Tibi,

Is it then weird that i don't have to press the cd door button?. I just press the play button after i put in a new cd and it just works.

Regards,
John.

It's not weird. First track will start but Shiga microcontroller do not know when this track stop.

TOC contain information about entire disc duration and where each track start and stop.
If TOC read is not initiated, microcontroller will use previous data stored in memory and obviously will fail to jump from track 1 to 5 by example, or will play first track start second and stop.

Regards,
Tibi

Just wondering if the most of people just output SPDIF to RCA directly? Has anyone use a pulse transformer?

Thanks,
Josh

Aslo the digital output J5 , the pin label as Dout should be positive or negative , i measure is negative ,so should be connect to outer of RCA , correct me if i am wrong , i jsut follow the diagram ,and measure the centre pin of RCA is negative voltage.

Thanks

The scope of a spdif transformer is to offer galvanic isolation and impedance adaption. If your DAC have an input transformer why you should put one at Shiga ?

On J5 nearest pin to s/pdif divider resistors, R48-R49, is digital output. The other one is grounded.

Hi Tibi
could you reply my pm as soon as you can.

Thanks

For those interested in BluThor, a GB is open http://www.diyaudio.com/forums/grou...timate-bluetooth-remote-controll-bluthor.html

Tibi,
Does Bluthor just replace the remote control we already have? Or does give any extra features? Thank You.

 

[iTiberius]

Bluthor also add power on/off function and CD door (TOC).
Also, you do not need to have direct visibility with CD player in order to control it.

Hi Tibi ,in that one Post You say "Also decoupling the XO with a 1nF silver-mica directly at XO pins brings even more resolution."
How to do that,just put 1nf between the 2 Pins of XO ?
Regards DT

Yes, decouple XO directly with 1nF silver-mica. Use very short leads.

Tibi

 

[taccodude]

Hi,when I do that Shiga won`t start.
Regards DT

 

[iTiberius]

Take care which pin are you decoupling.
Silver-mica cap must be in same position as the 100nF cap (near to XO) in below Tentlabs picture.

Tibi, Yesterday I changed the SMD Resistors You told me and I have to say this is another WOW Effect for me.So much more Details and Realistic. I wonder how far the Journey
goes ?! For me this is the best Transport I ever had.
Regards DT

Sir,
What did you do for R11, and R12? I don't see any 180K Z-Foil surface mnt. resistors on Texas Components webpage. Thank you.

 

[taccodude]

As I couldn`t get those SMD Resistors here in small Quantity, I used Takman Carbon Film.
Would like to test the others.
Regards DT

SMD Resistors

Tibi,
If one was inclined to change these SMD resistors (R7-12, R39,R40), what would you suggest for R11 & 12 ? The naked Z-Foils at Texas Components only go up 100K. Thank You.

 

[iTiberius]

You can use mini-melf all around or look for Vishay Z-foil smd.

Tibi

Hi Tibi
Is there a way to resemu once i pressed stop? It always start from track 1 after i stopped it.

 

[iTiberius]

You can pause a track by pressing play again. To resume, press play.
You can jump to any track you like from the start, just use left - right arrows to select the track.
Operation is detailed in Shiga manual https://docs.google.com/document/d/...nuOWdM-j9X4b7Q0/edit#bookmark=id.wisapv43g0iw
