To get the most from a direct box, your mixing board must have balanced mic and/or line inputs! (Note that some mixers offer both XLR and 1/4 balanced inputs -- check your manual.) Use a direct box if you are experiencing hum, buzz, or radio interference, or if your instrument's cable is longer than 20 feet.
When a transversal (any line that passes through two parallel lines) cuts two parallel lines then the angles that correspond to the similar positions (angles in the matching corners) with respect to either of the parallel lines and lie on the same side of the transversal are called the Corresponding angles.
Definition of Corresponding Sides. If the relative position of two sides is same in two figures, then they are called Corresponding Sides. Corresponding sides are proportional in similar figures. In the figure, triangles ABC and XYZ are similar. The relative position of AB and XY is same, so they are corresponding sides. Similarly, BC and YZ, and AC and XZ, are corresponding sides.
