update-preamp

Finally, I have finished the earlier mentioned pre-amp. More like

a prototype here. Built a casing for it from what I had in the 'store'..

Will need to improve on this. It's a passive preamp anyway ;)

Wow another Jaztech marvel.....what else can we say. I believe the originator "the bomb + detanator" is mean killer stuff, how would you rate this one???? :P :P :P

jazzy939 said...

Terribly 'neutral'.. just like a 'wire'.. hehehe

Gabanyayaya said...

jazzy what's the advantage to have a very passive preamp???? and how's it contribute to sound quality????

MadZiZ said...

GBY.....go google up la, tak kan nak spoon feed :P LOL. Acah je, jgn merajuks k:P

jazzy939 said...

GBY,
Passive preamp should NOT contribute anything to the signal path.. :D

Gabanyayaya said...

jazzy bro....can u help me....how to hook up a sub woofer to an integrated stereo amp.....like detnator or any hifi integrated amps....

jazzy939 said...

GBY,
depends on the subwoofer input.
some have dedicated subwoofer(single RCA input)
some have high level input form speaker out connections from the amp.Mine have combinations, so depends what is available from your amp also. Have to see first la.. got pix ah?

GBY,
Have seen the schematic. EASY.
Either you use a spare TAPE OUT from you amp connected to your sub LINE IN or use a spare(remote) speaker OUT to the sub's SPEAKER IN. Can your amp drive 2 sets of speakers?

For good sonics, I'll advise you to use the RCA's input.

Gabanyayaya said...

yes my amp can drive 2 speakers....but how's the connection???

ok so i have to use tape out connect to subwoofer level in using rca AND turn on the recording knob to tape rite....?


so how about detonator? can it support subwoofer too?

jazzy939 said...

GBY,
If you have a 'recording' knob on your amp,yes, set it to what ever source you are playing. This is only applicable if your amp allow you to listen to a source while recording from another source.
The Det' can be made to suit.. no big deal :D

Gabanyayaya said...

ok thanks...detnator also can ok good...i just don't want to waste the sub since keep it wrapped in my closet over the years....tengkiyu

Gabanyayaya said...

jazzy bro when will you go shopping for audio stuff again at j.p or farnell???? i wonder if can tumpang few things here???

jazzy939 said...

bro razzz,
Most of my electronic needs come from JP. Have NOT required farnell 'assistance'yet. hehe.
I may be going there this weekend though.. just planning. So what do you need? No fancy stuffs eh.

eiy jazzy its me lah...gabanyayaya. i change my user Razzz for a while since i'm selling something. my signatune name is not marketable le....current name is ok lah....

so Madziz buy already TT...a very antique TT i guess...why want to restore? though Madziz always go for exotic/state of the art one rather that restoring old stuff...how many LP you got during shopping?

oh...sorry....i need few things but can you get this is in JP...? i think farnell got la...

1. MK Plug hospital grade (Red)
2. Schurter IEC male plug
3. BNC Male to RCA Female converter

err...this is an exotic item rite...i also diy hehehe

jazzy939 said...

GBY,
yes.. I realized it was you after that!

1. MK Plug hospital grade (Red)
2. Schurter IEC male plug
3. BNC Male to RCA Female converter

I doubt it if I can get the above. I can get IEC male plug alright, but Schurter? Not in Jalan Pasar!
BNC Male to RCA female probably can.. have to ask. Kalau takder boleh DIY kan? BTW, Why an MK red colored plug? What is hospital grade?

Gabanyayaya said...

jazzy...yes that mission speaker is mine and i'm selling it since it blocking my way in my tiny room....

ofcorse you can't find it in JP...if you can't then i probably have to go to farnell my self to get these stuffs on the counter just like you said. BNC Male to RCA Female converter can get la in JP. That is a common item. Is just that I need to find the real 75omh type. Maybe you could get some since JP is your play ground...

Why MK plug red hospital grade???? Well most people said this plug is much better that normal one for quality even though I still don't get it....:> (bias...bias)

that iec is good quality ka???

jazzy939 said...

BGY,
As far as JP goes...
there are cheap ones and there are better ones, it's a matter of how much you want to pay. Meaning there are RM1 3 pin plug and of course RM12 pun ada!

I have bought a few IEC(plug and socket, for the Det'nator and d'Bomb of course!) from the cheapest to slightly 'better ones'.. I think it's a matter of how much you wanna pay for it.

Yes, some people can detect sonically the difference between cables, plugs and what nots. Thank got I have NOT reached that level yet! However, good quality plugs should complimenthi grade/quality devices.. ;)

what kinda expensive plug is that? any brand????. is it some kinda imitation of american plug? quality???

oh by the way is it really easy to push up the detnator from 40W to some where like 60-90W? My speaker rated at 91dB. But actually by measurements its only at 90.8dB. This will give a slide differences.

not feeling well la this few days...haiyyah....

jazzy939 said...

GBY,
Why do you need up to 90W? You play disco music?
Your speaker is rated in the high efficiency category, as such you don't need that high power. Jangan la jadi macam MDZ! I am happily driving my TLD with the D'Bomb at 9o'clock level of the volume control.. infact a 20 watter can happily drive your speaker already.

Gabanyayaya said...

Madziz already sold every thing la except that Atol. Guess he have that and the TT la. Don't know what speaker. U think detnator can outperform Atol?

Do you have any of your creation that can eliminate my fever here? Been 3 days now lying on bed not doing any thing....:(

jazzy939 said...

GBY,
I believe he still have that speakers.. He may have a new hardware which I am supposed to drop by to check it out..

Fever? No lah.. just let your antibodies do their work.. it'll just take some time?

Det'nator outperforming the Atoll?
Can't say.. it's all subjective you know.. sonically. It is more of system balance. Last I heard of MDZ's system it was well balanced. Made possible by the Atoll and that Tablet combination. I have yet to test D'Bomb with it. Why are you comparing the Det'nator with the Atoll? You liked the Atoll?

jazzy939 said...

Oops NOt Tablet, but ProAc... was thinking about the Tablet.. the apeakers!

Gabanyayaya said...

since when he had a ProAct????

look at buy and sell web site you'll see his italian speaker sold!

syyyy...hek hek hek don't tell him...

jazzy939 said...

GBY,
The ProAc was quite recently.. tak sampai sebulan kot.. abt 20 years old.. but the saound, wow! Better, in the sensed that it partnered well with the Atoll. British speakers at its best!
