Now consider what occurs when the television is turned on and the home theatre is completely engaged...

First, the main oscillator is activated by the on-board computer. This excites the horizontal circuitry, which is used to produce not only the high voltage and high amplitude waveforms that are needed for CRT scanning, but also the scan type power supplies used to power the other circuitry. Vertical sweep is also started, usually provided by a master oscillator divided by other circuitry and then amplified by a small power amplifier, which is then coupled to the deflection circuitry.

While all this occurs, color circuitry is started as well as video and the delay circuitry. Audio, usually treated as a stepchild, is brought on at this point, or as soon as the signal is detected from the tuner and mute is released.

As the television reaches full function, ALL of the circuitry is NOW imposing its noise on all the rest (in smaller amounts) also on the line. The surround decoder, line doubler (in the case of big screen types) and all of the associated audio support pieces have their signals imposed on the line as well. This can actually become noticeable in the degradation of the audio and picture that the system is capable of producing. Plug your HDTV, BIG SCREEN, SUPER TUBE, LETTERBOX and BIG TUBE as well as your other televisions into one or more units and see how much perspective and already fabulous picture gains from Richard Gray's POWER COMPANY™!
