Default Tubey techy tidbit.....


OK, here's a nice little tidbit for the techies in here, if anyone wants
it - I've got a couple of these little Tubey mic preamps:

http://www.moirac.adsl24.co.uk/showntell/MicPreAmp.jpg


Which you will see have a 'third knob' for 'ART's new V3 (Variable Valve
Voicing) Technology'...???

I've always ignored it and used it 'Flat' but what does it do? What's
actually happening/being done to the signal when it is turned through the
various 'instruments'? (I'll have to have a fiddle with it sometime!)

There's more info on this eBay auction for a similar item:

http://cgi.ebay.co.uk/ART-Tube-MP-St...em335 9dabccd


Also, see: 'Excellent as a Tube DI XLR and 1/4" Inputs' - does this mean I
would/could run a keyboard or (dare I suggest it) a digital piano through
one of these with some expectations of success?

(Swim's joanna is buzzing due to splits in the soundboard, apparently -
might mean summat digital is a quick and easy solution for simple backing
trax for the time being, if and when necessary!!)

TIA, as usual.....

Interesting, the 64 dollar question is does the 'flat' setting on the VVV knob
actually bypass the processing circuitry completely...I'm a pure path fan
myself. I realise the other settings could be useful but then I know sod all
about mics and recording.

Right on the money, Bill - I think the recent Neumann has prompted me to
revisit the recording side (of which I also know diddly-dick) and I have
suddenly *noticed* those voicing knobs!!

I'm prompted to consider upping the game a bit with a better (Neumann or
what then?) pre-amp and power supply and found this on my travels:

http://www.micshop.com/


Now, mutual lack of mic and recording knowledge notwithstanding, ain't that
a *lovely* sight?

:-)

There is no such thing as flat, bypassing all the circuitry. There is always
some capacitance etc, in any circuit.

I was referring to the VVV processing circuit [fairly obviously]. In the pure
path sense bypassing is usually taken to mean removing source switching,
tone/loudness and balance controls from the circuit.

BTW, why do you top post? It's not big and it's not clever.

Having a fiddle with it will probably tell you immediately what
the presets are. Perthaps they have built in EQ and or compression?

There's more info on this eBay auction for a similar item:

Yes. Switch off the phantom before plugging in or out.
There is a gain control bottom left.

Have fun

A fiddle it's going to have to be!! :-)

OK, here's tonight's fun - Swim Bo got a Duets book today, so here she is
playing with hers... - never mind:

http://www.moirac.adsl24.co.uk/shown...derleyDuet.wav

http://www.moirac.adsl24.co.uk/shown...heMoonDuet.wav


Hideous yet strangely compelling, eh?

:-)

I can't tell you what a faff they were to do with only two tracks to play
with and having to stretch tracks to match on one of them- first job was
record the bloody metronome (twice)!!

Now, breaking news: Amazon MP3 anyone?

http://www.amazon.co.uk/b/?ie=UTF8&n...l_7hr7gagohn_e


Or is it old hat?

(I wonder if they got mine and decided to start a new business section with
them???)

Most devices that suply phantom power, do so to
XLR sockets only. But there are exceptions. I have
a Ducane supply where the DC appears on the
TRS connectors also.

So it is good practice *always* to ensure the phantom
is switched off before inserting or removing any connector.
That way you won't get caught out.
