Phase indicates the output phase selected. Press and hold the filter/phase select button for approximately two seconds to select normal or inverted phase output. When the led lights up, the phase is inverted by the dacmagic. If you suspect that your source material or amplifier, etc., is inverting t...

18 the dacmagic dsp has three different filter functions: linear phase, minimum phase and steep. All three filters are highly sophisticated audiophile topologies, optimised specifically for audio playback. In our opinion, these filters offer excellent sound quality but differ subtly in optimisation,...
Page 19
Dacmagic azur 19 the linear phase filter is a highly regarded audio filter offering low ripple in both the pass and stop bands, and what is known as constant group delay. Constant group delay means that audio signals of all frequencies are always delayed by the same amount when passing through the f...

Dacmagic azur 21 english the minimum phase filter is another highly regarded audio filter that offers even lower ripple in the pass and stop bands. Unlike the linear phase filter, group delay is not constant so some time- coherence is lost; however, phase shift is low and the particular benefit with...

Dacmagic azur 23 our steep filter is a linear phase filter that has been optimised for stop band attenuation of close-in aliasing images. Here we have traded a little attenuation of the very highest frequency response (-2db at 20khz) and a little more pre- and post-ringing for a very steep attenuati...
