-<h2>Panning is not Balance</h2>

-<p>
-  If you are used to the "balance" control found on most home music
-  playback devices, and on many DAWs and audio editors, you may have
-  gained a particular idea of how "panning" should work. You turn the
-  knob to the left, and the signal in the right speaker gradually
-  vanishes as you do. You turn it back to the right, and the signal in
-  the left speaker vanishes in the same way.
-</p>
-<p>
-  This is <strong>not</strong> panning. It does not alter the placement either the
-  left or right signal, but rather is just a different term for
-  "independent gain control". What is actually happening is that as
-  you move the balance control left of center, it reduces the volume
-  of the right channel towards zero, but leaves the left signal at
-  normal volume. When you move it back to right of center, it reduces
-  the volume of the left channel toward zero, and leaves the right
-  channel at normal volume. When the control is exactly in the middle,
-  both channels are at normal volume.
-</p>
 <p>
-  The panners in Ardour control the distribution of at least one
-  signal across at least 2 outputs. Ardour does not (currently) come
-  with a balance control. Many people would like to see one.
+  In addition to the panners, Ardour has a stereo balance control for subtle
+  corrections to an existing stereo image.
