6 Analog vs. Digital Audio - This refers to the method used to place audio information on the source material and how they are delivered to your preamplifier from the source. Analog signals exactly represent the sound you will hear through a continuously varying voltage. Audio cassettes are analog recordings and are normally delivered to your preamplifier over a pair of coaxial audio cables. Digital signals closely approximate the original audio signals with a set of numbers referred to as a bi

9 waves is a desirable effect to a point. Different locations in the room will have waves that collide with one another. This collision can cause a superposition (addition or subtraction) of the audible wavelength. In either case, these locations are referred to as nodes. If a positive node occurs in the primary listening position, that frequency drowns out all other frequencies at that location, resulting in limited frequency response for that location in the room. A node can occur at any f
