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.

I've seen plenty of installations where the console supplies the phantom
powering so that goes via the jackfield.

The best method IMHO in a studio is to apply the phantom direct to the XLR
input on the wall box - with no means of switching it off. Never had
problems with any pro mics of all types doing this. It is after all what
it was designed to do - be transparent to a non powered mic.

Why does it need to go to the jackfield? The mic inputs are
usually XLRs on wall boxes, and hardwired to the console
inputs.

But what we are talking about here is a small preamp/FX
unit that Keith has, which also supplies phantom.

Which is switchable.

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?

Yes. There's no need to worry about the phantom voltage setting because
the user manual states that the phantom power is only available on the XLR
input.



Which is good, but that's the 'Also, see' - what about this bit:

"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!)"

But before you bother to start Googling, please see my other response re
'advice' below....

I'm surprised no-one's commented on these - if only to take the ****!

One of them (if not both) sounds like the signature tune from some
diabolical 70s sitcom!

Terry and June? Robin's Nest?

it do?

It does a number of things.

In the first generation of this device, there was a knob like this that
varied the ratio between signal that went through the tube, and the signal
that bypassed the tube. In short, it controlled the amount of nonlinear
distortion.

In this generation, they've added other functions that appear to be layered
on top of the control over added nonlinear distoriton that was always there.
One of the added functions is no added function at all. IOW it duplicates
what earlier generations of the device did.

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!)"

Here's the key Keith. It is obviously a device that has an audible effect.
As the operator of the device, it is up to you by experimental means, to see
how it effects the sounds of the various instruments that you process with
this box.

I would hook this thing up in a normal signal path for playback, and play
back various recordings and find out what the audible effects are, in
accordance with your perceptions and preferences. Treat it like a tone
control or some such.

That's what an intelligent person does with any audio signal processor,
especially one with a number of knobs to turn.

To avoid making super-duper transients when you plug and unplug jacks in the
jackfield?

If the phantom power bypasses the jackfield, every mic that is plugged into
a wall plate constantly receives phantom power, whether it is jumpered into
the console or not.

If the phantom does not bypass the jackfield, every mic that is plugged into
a wall plate eceives phantom power only when it is jumpered into the
console. If you unplug and plug jumpers on the jackfield, the phantom is
applied and removed from the mics. Applying and removing phantom power from
a mic usually creates some pretty big transients, especially if the mic
relies on phantom power.

The mic inputs
are usually XLRs on wall boxes, and hardwired to the
console inputs.

But what we are talking about here is a small preamp/FX
unit that Keith has, which also supplies phantom.

Which is only applied to the XLR input, when it is turned on.

Most pros avoid stuff like this. It's an EFX box masquerading as a mic
preamp.

Most pros track clean, and apply EFX in the mix.

What TF has what 'most pros' do got to do with me or just about every other

(If you rummage about about a bit, there's a hint in there for all 'pro'
