Mini Dac TDA1543 X 4 NOS - Page 52

post #766 of 950

 

im talking regards to the amount of bass- dc coupled gives no attenuation. I think it has something to do with impedance but i'm not technician. just going by what my ears and those who are more learned than I am have posted here and other places across the web.

 

do your own research, make your own conclusions but don't condemn one's reporting as false info lest you want to look the part of a fool who assumes that everyone's system should work the same way as yours. 

 

and yes your syntax is very crooked; consistently.

I'm sorry, but thats not the way it works. If you want to claim certain facts you will have to back it up with quotes yourself and not relegate the research to others. You don't just fire blanks and leave the burden of evidence to others. Back up your own statements.
I have already modded 10 of these DAC's in different versions. I know first hand what I'm talking about, not hearsay.

I just said that I have noticed no bass attenuation in several setups. And that certain ppl need to hear an improvement after doing expensive mods. Thats just basic psychology.

My statement is meant as an apology. I'm not native English speaking. I consider your affirmation as quite rude and unnecessary.
PS: actually, I was apologizing for your lack of comprehensive reading.Go figure... rolleyes.gif

Of course I would be offended, as anybody else would, when you contradict me by saying that I'm giving out the wrong info by CONFIRMING with me what I've been saying! xP. Also I was never trying to claim any facts but only share my experience of the mod which still COINCIDES with your finding. 

 

but I don't think language barrier is the root of your problem. 

 

Your problem here is that you've been sniffing too much of that cheap chinese pcb resin during soldering.

 

now please go spin someone else's yarn.

hey, I said I'm sorry. Flinging insults isn't going to help.

pls explain:

the bass diminishes if you dc couple it which was even shown on a graph earlier this thread.
What graph was that? I still don't know what you're talking about. By diminishing bass do you mean overall or a high pass?

i think you need there 10.1 uF + replace 680R to 910 R ,this way the filter goes to 17hz bass

Move over Muse, this little guy is better, smaller and... French?

Outstanding sound quality. No roll-off, better instrument separation and depth than stock Muse.

Of course it has roll-off, its NOS with passive I/V. How can it not be -3.2dB @ 20kHz?

post #774 of 950

Here we go. Please note my sentence is making a direct comparison with the stock Muse.

French you say? Thats one reason not to believe him (chauvinism alert).

Where is the case?
Where are the other 3 tda's?
No power supply supplied.
All smd parts.
Price?

Huuuge capacitors on the output path provides sub-Hertz cutoff frequency (<0.3Hz on a 10kOhms input)
big means cheap type elko? No thanks.

WTF? More than 2 hours. Wow! blink.gif

Thanks but no thanks.

must I buy this one too to hack up into another flux gobbed mess? i think $80 is asking too much, though.

Hello to you all. I am new here and I was trying to find some solution for my problem with MUSE TDA1543x4 DAC that I was received about 3 weeks ago.

First of all I have to say that this is an awesome thread, that actually made me to buy particularry this DAC.

It came on white PCB with listed 13-18V near the DC plug. First I was using the DAC for playing music from my PC through M-Audio 24/96 soundcard's SPDIF coax output.

From my experience, the sound is pretty good, but from time-to time gets interrupted by some sort of static. Sometimes it would start right away (with cold DAC) and sometimes it would start later, when DAC gets little bit warm. This happens no matter of what PSU I use (I have original one that came with the unit, as well as commercial - linear one). Did not do any mods to the unit.

 

Anyone has an Idea what is wrong here? Did I get an faulty unit? Any answer would be appreciated.

 

Thanks!

 

Sasa

I needed some time to think about it. Your problem sounded familiar but I couldn't remember what it was.

Check if you are not sending it more than 24/96

If you are using coax try optical instead. Sometimes the coax can pick up RFI from the amp if the lines are close to eachother. Or make sure the signal doesn't run parallel to speakerwire or anything.

If you want to reduce V for the dacs to a safer 7V use a 450 Ohm resistor for R01.

Hi,

 

Has anybody found a decent Lithium / Lithium-Polymer battery solution for the MUSE yet? I'm interested in the DAC, but the form factor makes it tempting to use with an iRiver H140... If it had a battery, it could be fun!

 

Thanks

This is what I have been using for the last 2 years for my transportable rig in tandem with my H140.

 

Usually lasts about a week before I need to recharge.
