can someone briefly fill me in as to why there was never a new thread about the new stuff on here?
Click to expand...

The short and skinny is: Chance didn't want a new thread. It really is that easy.
 
I've been so busy I failed to post here. we're having problems with some of the 81's. My tech wants to help but is in England till after the holidays. I posted on PSW more info as to what the problem is. Many orders have been shipped, but the console has not been updated yet. You will be getting E-mails from Fed Ex or USPS if your order has been shipped.
 
Woohoo! Got my invoice and paid this morning. My work is done. Now I can sit back and wait to see when my early Christmas present is going to arrive.

Well, the ICs are driving the LEDs, so I'm not sure you'll gain a lot by swapping ;)

. . . and other than ease of modding, what is wrong with SMT? SMT parts usually have a tighter tolerance, etc.

SMT parts have a bad reputation mainly created here, and spread about as fact by uninformed people talking about pre-amps. In reality, SMT parts are the same in operation and allow smaller footprint/denser designs.
 
I am unable to log into the console, any ideas besides try again or use password as my password?
 
It seemed i couldn't log on to the user console unless i requested my
password , then without getting it , i could log on , BUT
what it really was , was changing the privacy & security settings
under the tools , internet options on the pull down menu [ Windows ]
try that should work

Re smt , personally i can't read em , not steady enough to solder them
and smaller wattage resister do exhibit greater thermal noise , no ?

and i'll take the preamps as soon as i can get them , hum issue or not
thanks , pateintly waiting to pay invoice

Uh, let me think about that, no.

Here is some fine reading:http://www.tutorialsweb.com/smt/chapter2.htm

OK, thanks Chance!

Quick question;
What are the typical shipping charges like?
I ordered a couple of pres and a mic.
Was thinking about driving down, but wanted to
see how much i might offset the gas.
Is it true that once it shows up on the console i don't
have the pick up option?
Also, anybody have any problems with shipping damage?
thanks

Same question here, but I only ordered one mic and no pres. :p

I'm in Riverside, so...
 
Logging on console

No problems logging on. Still got that big red NO on items shipped. Oh Well it will be nice when it changes to YES!!!!!

Actually it is true, but irrelevant.

http://en.wikipedia.org/wiki/Thermal_noise

Given that noise equation, noise is a function of the temperature of the resistor. A larger package will dissipate heat more rapidly.

However, that would only be an issue if a resistor of inappropriate rating was used. There are SMT resistors in various ratings, although if you want 1/2W or larger, you're probably using through-hole parts.

For a preamp design, except for that output stage and the power supply (and phantom power), there should be relatively little power dissipated in any given resistor.

But let's say you have a SMT resistor that was running 20C above a through-hole resistor of a larger rating, running at ambient temperature of 25C (298K). According to the thermal noise formula, the increase in noise will be:

dB = 20 * log ( (318K / 298K) ^ .5 ) = 0.3dB

Does that mean the noise of the preamp will increase by 0.3dB? No, not necessarily, because the preamp's noise might be (probably is) dominated by other factors, such as the noise of its active components, or even the noise of the connected microphone.

Yes, but because SMT has a bunch of other advantages, the extra "noise" can be designed out in the layout which can eliminate other problems. Through-hole components have limitations in the layout of the PC board that could, and do, introduce other "noise" sources. SMT allows much more flexibility in this area. The main reason that SMT is shunned in the audio world is the discreet vs. integrated IC battle. SMT and Through-hole ICs are identicle in operation and audio snobs hate both formats.

Hey, I'm a SMT fan, remember!

You can get SMT discrete components too . . . I think audio snobs are jealous because they can't do SMT rework :p

Having said that, I prefer through-hole rework, but SMT assembly.

Then gear snobs should be twice as jealous because I CAN do SMT rework (except BGAs, of coarse).

Chance, For those of us who ordered 81's, care to share more with this board or post a link to PSW so we can be up to speed. Thanks
 
Is there any separate thread on GB gear review in any forum? I'm still waiting for my shipping invoice... :cool:
 
I'm going to the wearhouse tomorrow
If anyone is POSITIVELY coming over on Sunday for your gear PM me by noon Friday and I'll bring your gear back with me.
