[UAP] Panning Behaviour

[UAP] Panning Behaviour

2003-10-10 by metafoetus2002

Hi,

I was able to aquire an Animal, just some month old, from Joe Millar. Very
smooth deal, good trader.

After the first blast of excitement, I discovered the following.

I feed a sine wave into the right input of the [UAP] and switch the [UAP] to Pan
mode. Now, when I turn the Pan knob from the middle position to the right, the
following happens: The right signal gets gradually louder, the left signal gets
gradually softer. So far, so good. But at around the 3 PM o'clock position of the
Pan knob, the left signal drops abruptly to zero level.

Accordingly, if I turn Pan to the left, the left signal gets gradually louder, the
right signal gets gradually softer. But at around the 9 AM o'clock position, the
right signal drops abruptly to zero level.

Also, if I set the [UAP] to Xfade, I can not do a smooth crossfade. E.g. I start
with signal 1 only -- at the 9 AM position of the Xfade signal 2 gets abruptly
switched on. And at 3 AM signal 1 gets abruptly switched off.

Is this strange or the normal behaviour of the [UAP]?

If this is how it is meant to be - although I find it hard to imagine that it should
be this way - I am fine with it, as this small panel is a powerhouse of an
electronic musical instrument, unlike any other I have ever owned or played. I
just want to have peace of mind.

In any case, I already ordered a [TKB]. Hehehe.

Thanks in advance, best regards,
Jan-Hinnerk

Jan-Hinnerk,

My UAP (also part of an Animal panel) behaves identically to yours.
This, I believe, is a function of the Serge "equal-power" panning
versus the linear panning we're generally accustomed to. Perhaps
some of the more experienced members can shed more light on why the
equal-power approach (which I think is designed to keep loudness the
same when at dead center as when panned right or left) causes each
sound to drop at its opposing 3/9 o'clock mark.

The drop you are referring to is the dreaded 3dB cut in the center caused by
panning via crossfading. Personally I can't go into details about how the
UAP overcomes it, as I don't know this circuit, but yeah, this is what the
equal power panning function is all about.

Interesting.
I still haven't found a module by any company that performs panning with a
minimum of fuss. Most modules I've tried audibly clicked between sweeps.

Chris,

thank you so much for verifying. I can feel peace of mind again :-)

Regarding the explanation, however, I am unsure if this PanDrop@3/9 is
caused by equal power panning. My Mackie mixer 1604 has equal power
panning, and it does it without level drops.

Reading EGRES/Wizardry/VCAs and Mixers, I discovered the following
paragraph regarding the response of Serge VCAs to control voltage:

>Below .5 volts, they want to attenuate completely, keeping noise minimized=
.

Do you think that this can have something to do with the PanDrop@3/9?
Perhaps at the 3 PM and 9 AM the voltage controlling the VCA of the side th=
at
gets softer and softer drops below 0.5 volts, so that the VCA shuts down
completely abruptly?

Or am I confusing things?

Thanks in advance,
best regards,
Jan-Hinnerk

Ups,

PanDrop@3/9 looks like an email address, but it was just meant to be an
abbreviation for the "Panning produces a level drop at 3 PM and 9 AM o'cloc=
k
position".

Sorry,
Jan-Hinnerk
