The GUTZ

[Hammer Mark]

I had the PCM70 open this morning to update the ROM version from 2.0 to 3.0 using chips I bought on ebay. I copied all of the v2.0 programs into the registers first so that I now have both versions in the same box. I had the PCM42 open to repair the IEC power cord socket and the 160xt open to add a power switch to the front panel. I can't remember why I opened the Pacifica, but it looks quite tidy.

really really kewl!!!

thx Hammer Mark & everybody!!!

I was under the impression that the "xt" indicated the presence of an output transformer. But yours just has a pair of wire links where the transformer should be.

Hmm. I thought that the XT was distinguished from the X by either balanced I/O or XLR connections (or both). An output transformer is one way to get a balanced output, but there are others. Anyone care to jump in on this one?

ok.. now the expensive stuff..

[alkooloid]

Man. That WSW stuff looks tight! As in awesome, but boy working on it must be hard. So compact.

[roginator]

nah ...not all compact WSW have 600 kg desks
and some BIG limiters!!!

i have much more wsw guts if you wanna see ....

I need to ban you. I am jealous

[roginator]

i can show more..... but i have feeling somobody would kill me if I go on with wsw.....

give me your adress.. I will send some guys with sunglasses, pistols and empty 19" racks..

please post more.

im a gssl builder ...calibrate GSSL IS EASY!!!

2 trims for THD on VCA.... or no trims if used pretrimmed THAT.... easy to trim any cheap Distortion meter would work...or good software like A.R.T.A wich is free

calibrating VU is joke and there you go with 3 trimpots on Super side chain..

so easy my kid can do that if he see procedure 2 times and he is 7 years old...

+ need dbm or A.R.T.A. again to calibrate in Output depending on VCA used in DIY GSSL!!!

Due to the lack of interest, we will shortly be closing this thread.

no! why?
it's my favourite thread!

I´m not sure, but I think you may have missed the last sentence written by Tim...Look again in his post

Kind regards

you're right, Sir

Here's a CA-227 preamp kit from Orphan Audio that I just finished. It sounds awesome! The PSU is the 2448 kit from Five Fish Studios.

Inside the Behringer Ultra-gain pro:


The LEDs are positioned behind the tube -- gee, I wonder why

Here for more: Will you ever buy Behringer equipment again after reading this?

Hmmm...Not knowing the circuit in hand, but the tube might be "in the circuit"..The 3 leds might just give the impression that the tube glows "more that it really does" or trying to help the tube to look more "glowing"..Marketing effect someone would call it...*S*..Tube "warmth" can be achieved to the audio in many different ways depending on the acturel design.. (mainly 2nd order harmonics)...and its pretty easy to do:-).

What seem to escape most people is that the ever soo often talked about "tube warmth" it more often also transformer "warmth" or distortions...soo units like the one in questions may deliver "tube warmth", but is greatly missing the transformer "warmth"...And that may lead to disappointments in many cases!

Again..I´m not familiar with the circuit of the Behringer units so take my post only as is :-)

Kind regards

I have the TUBE ULTRAFEX T1954 and replaced the stock tubes with a pair of EH tubes. I use this gear to thicken the sound of guitar processors and it does a great job for that purpose. I ought to add a pair of transformers to it now.

If you are satisfied with what the unit does to your audio...I for one would would not waiste more money--trying out different transformers, But if you would like to have an "extra option" of more level of "warmth/distortions/core saturations"...and/or phase shifts..etc By all means try some of them out *S*

It is cheap tube warmth, for poor people. The real tube warmth means absence of high order distortions, especially of crossover type ones that grow up with lowering of a signal level. Such a "warmth" can't be added by any additions, be it a tube, or transformer, or whatelse.

It is impossible to add absence of some types of errors.

Hmmm... could somebody possibly post the gutz of a Quadraverb 1 Revision F?
I got one slightly modded and want to undo the mod, so a closeup of the PSU part would come real handy

[KingDiamond]

We opened up my friends' Steinberg/Yamaha MR816X and took some pictures. Here is one:



The ADC is an AKM AK5385 24BIT/192KHZ
The DAC is an AKM AK4358 24BIT/192KHZ
JM2068 Op-amps
Wavefront Dice II chip

Well you´re correct...but it does not have to cheap "warmth" for poor people..think of some of the original NEVE circuits...they add some of the same transformer distortions as transformers would do today ..but at an much higher price level!!

I doubt you´ll see the tube circuit in the unit talked about having any trouble with X-over distortions ;-)..I belive its a 12ax7 in there..most if not all 12ax7 tubes have high distortions...with carefull circuit design they can be controlled to be mainly 2nd ...even with unregulated psu and absence of any CCS´s etc...

I think I might go buy one of them units just to see *S*


Kind regards

...but ma be it is because of single ended circuitry (the main reason) and absence of input diffstages (to cut costs on transformers)?

Right; that LEDs may produce a reference voltage for a CCS that loads the tube, to minimize it's distortions. Last Behringer's schematic solutions are smart, I have to admit. Besides another smart solutions his company copied.

I would be glad if some day he contacts me to design something for them...
