With the AD9Pro, aliasing and clock noises that were considered typical in analog delay circuits have been minimized to the point that they are virtually non-existent. With a Dynamic range that is 18 dB wider than the original AD-9 and a maximum input level of +12 dB, the AD-9 Pro can be used with any input signal. This improved low range response yields a bold sound not normally associated with analog delay, and the superior balance between low and high range that the AD-9 Pro offers creates a delay tone that is simultaneously clear and firm yet retains the characteristic warmth of analog. Furthermore, the wider dynamic range allows the AD-9 Pro to be used in the effects loop of any amplifier without creating signal distortion or level disparities.
