Hi,

I like to choose one channel only in a mic pair, to isolate one side of the pair.

There are two Balance controls in the Synchron Player mixer: the slider under the Power Pan, and the knob when choosing Balance mode for that control.

Are they equivalent, or do they work in a different way? If they are equivalent, I will probably prefer the one combine with the Power Pan, to exploit both controls.

They work differently, Paolo.

The Balance slider is effectively two synchronised mono faders: one determines only how much of the left input channel passes through to the left side of the stereo output pair, and the other determines only how much of the right input channel passes through to the right side output.

The Power Pan control is an adaptation of the analogue mixing console type of stereo pan controls, as still modelled in ProTools and a few other DAWs. In this case left and right input channels each have an independent mono-to-stereo "pan pot" (panorama potentiometer) which shares its single-channel input audio in any user-set proportion between the left and right stereo output pair.

One important difference between these two types of panning is that when the Balance slider is set hard left, nothing from the right input channel passes through to either side of the stereo output pair; it is effectively muted. In contrast, when Power Pan is set hard left, both left and right input channels are mixed into the left side of the stereo output pair and nothing passes through to the right side.

I don't want to get into detailed comparisons of using these different types of pan control, but it is worth keeping in mind that when you have 2 input channels that, as a pair, contain recorded "dry" stereo information, such as in the VI Appassionata strings library, using Balance to place that sound somewhere in the stereo sound stage may not turn out to be quite as satisfying as when using Power Pan.

Macker, thank you for your answer, but I think my question was not clear. I know the difference between balance and pan, but Synchron Player has a balance control also when in Pan mode.

The Pan/Balance control can work either in PowerPan or Balance mode. When in Balance mode all is clear: you get a knob letting you balance between the left an right channel, changing the level of each one separately.

When in PowerPan mode, you get the complex pan knob, but you also get a balance slider under it. Is this one working as a standard balance control? How does it interact with the pan control?

I haven't tried to use both types together in my Synchron Players (nor in my VEPro, where the combination also appears). I can only guess that balance happens after power pan but as for the combined effect, I haven't thought about it as I don't see any use. Maybe VSL can clarify.

I can guess that the Balance slider strengthens/selects one of the channels, and the PowerPan knob works on the resulting signal. I can't yet understand from my tests.
