I own a G-6000, and I was reading the frequency response specs, How do I access the "power amp in" Frequency response of 0-200,000Hz. Would I just defeat the tone controls to do that?
we are designed to listen - optimisticaly - from 20Hz to 20 Khz - and that will happen if your speakers are capable to reproduce such frequencies in a +/- 2dB aong the audio spectrum.
In other words, the tone controls are just to equalize room interaction and personal taste with musical material. Realx and enjoy your system !!
