19. n The maximum output voltage that any amplifier can pro duce is limited by its power supply Attempting to output a voltage or current level that exceeds the power supply limit will result in a flattening effect on the signal A clipped waveform exhibits extreme harmonic distortion making it sound harsh or dissonant The clip limiter detects this and reduces the gain to minimize the amount of overdrive To preserve as much of the program dynam ics as possible limiting reduces the average program level until peaks barely clip Each channel has its own clip limiter which can be switched on or off When driving full range speakers clip lim iting reduces high frequency distortion caused by bass overload It also protects higher frequency drivers from excess overdrive and harsh clipping harmonics HPF Hi Pass Filter Also known as a low cut filter a High Pass Filter rolls off signals below 40Hz The reproduction of the signal s bass portion is thus optimized since ultrCV low distracting frequencies are eliminat ed and more power is available for the reproduction of the want ed segment of the signal You should set up the filters so they best suit the frequency response of your speakers since some speakers are particularly sensitive to over excursion The 40Hz filter works well with most compact full range speakers di ae d ae SPEAKER COMPATIBILITY The CV Series of amplifiers are designed to work with man
