EQ Control Response
Fader Response
These graphs show curves representing upper and
lower limits for gain response verses fader position.
Contour controls allow smooth, continuous adjust-
ment between the two responses.
MODE 1 acts like a regular volume or crossfader.
MODE 2 acts like a stereo pan control, with the
center position as off. With the Contour control set
slow, moving the Crossfader right reduces the left
channel to silence, gradually increasing the right
channel volume at the other extreme. The MODE 2
graph shows the response of the left program channel.
The right channel is a mirror image. Both can also use
the Reverse switches. See the TTM 56 Manual for
illustrations of these combinations of effects, down-
loadable from
