Vox Valvetronix amps?

Re: Vox Valvetronix amps?

Hey, ErikH, have you noticed any difference between 15/30W and 50/100W, considering that last two have Celestion speaker inside?
I really do find my AD30 sometimes muffled, like it needs to be brighter, but something I can't get with trebble control.
I will try it out with some ceramic pickups, mine are crappy

Re: Vox Valvetronix amps?

You may know this already, but there are two very different amp lines in the Valvetronix series. The "real deal" professional models are the AD60VTX and AD120VTX. They are fantastic and are miles ahead of the other models, tone wise. The other models in the series, the ad30VT AD50VT and AD100VT, are good, don't get me wrong, but they aren't in the same league as the 60 and 120 tone wise. They are built with lower cost in mind and sacrifice some of the authentic tone, as well as versatility in the effects that are included, and the amount of programing that can be done. I have the AD60VTX and absolutely love it. I play it more than my Marshall TSL, or Fender amps combined. I also have the AD30vt amp and it is fantastic for the price and much more portable. You can't go wrong with the cheaper models, and the more expensive ones ARE worth the money.

My understanding is that the AD50/100 series uses a higher sampling rate to get a more true-to-life tone than the AD60/120 series.

The models between the "silver" and "blue" series are the same. The only difference is there are less of them and less features in the "silver" series. And yes, the "silver" series does use a higher sampling rate.

The speakers make a huge difference with these, or any other amp. The Celestion is voiced specifically for these amps (in the AD50 1x12 and AD100 2x12 combo). It really opens them up. I've had mine up to blasting the drummer out levels before with very pleasing results.

Re: Vox Valvetronix amps?

Its like this:
AD 60/120 VTX are 48 KHZ with 20bit AD/DA codec
AD15/30/50/100 VT are 44.1 KHZ with 24 bit AD/DA codec

The first is the blue series, using Vox NeoDog speakers (by Celestion) , more expensive, muck more versatile, with 16 amps inside.

The second is the chrome series, usin plane Vox or Celestion 70/80 speakers, with only 11 amps moddeled, with lower samling rate (44100Hz) but with 24bit resolution (meaning 16 times more precise AD/DA conversion).

If you get a metal one, make sure it is isolated from the chasis you could run in to a ground issue. That is one of the reasons it's plastic. Just make sure it's on there good and tight (not too tight) and then apply some clear nailpolish like I did. That sucker hasn't moved once on me.

Thanx Erik!I really appreciate your help!Thanx bro!

No problem.

Cronnin, the resolution is what I was meaning. Thanks for throwing that stuff out there. 44.1kHz is what CD's are sampled at. Not all that much of a difference to the human ear between 44.1kHz and 48kHz, IMO.

Re: Vox Valvetronix amps?

Yes ErihH, I forgot to point that 44.1KHz is a CD sampling frequency, and it is more than enough for quality sound.
Why? Human ear restrictions and Nyquist theory.
The theory says that the sampling rate needs only to exceed twice the signal bandwidth.
So, since humans can't hear above 20KHz, the bandwidth is cut at
22.05KHz, and in order to retrieve the full signal after DA/AD conversion we need to have
2x22.05=44.1KHz sampling frequency.

For those who want to know more, see:
http://www.lavryengineering.com/index_html.html
(check out the Support part)
you have sampling theory in pdf there (and much interesting stuff),
but you have to be an engineer of Digital Electronics to get that
..which I am not

So, to conclude..it is not ONLY 44.1 its the fabulous 44.1 KHZ
