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.
Adjacent Angles are 2 angles that share a common vertex, a common side and no common interior points. (They share a vertex and share a side, but do not overlap.). Vertical Angles are 2 angles whose sides form two pairs of opposite rays (straight lines).omplementary Angles are 2 angles the sum of whose measures is 90Â°. Complementary angles can be placed so that they form perpendicular lines, but do not have to be in this configuration. THEOREM: Complements of the same angle, or congruent angles, are congruent.
