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.
A parallelogram is a quadrilateral. There are many different types of parallelograms. A rectangle, a square and a rhombus are all examples of parallelograms. The opposite angles of a parallelogram are always equal. Both pairs of opposite sides are also equal. Adjacent angles of a parallelogram always add up to 180 degrees. The sum of all four angles of a parallelogram is always 360 degrees. A hexagon has six equal sides and six equal angles. Each angle of a hexagon is 120 degrees, and the sum of all six angles is 720 degrees.
