DAC Filters
The SA35 has the option to select between a number of digital filters that are used in the digital to analogue
conversion process. Digital filters are required to minimise unwanted distortion in the output but no filter is
perfect, there are always compromises between a few parameters:
1. Frequency response - audio level across audible frequencies. Ideally, this does not vary significantly
between 20 Hz and 20 kHz.
2. Phase - The time delay introduced between reproducing dierent audible frequencies. Ideally, this would
be as low as possible (linear phase).
3. Ringing - Additional audio artefacts that precede (pre) or follow (post) the audio. Ideally, these should be
as low level and last for as short a time as possible.
The following filters are available for selection in the SA35:
Minimum Phase - Fast roll-o preserves output level to 20 kHz with no pre-ringing but extended post ringing.
Linear Phase Apodizing - A compromise between frequency response and ringing. Very slight reduction in
output level of the highest frequencies. Pre and post ringing are equal and low in level.
Linear Phase Slow Roll-o - Measurable reduction in output level of the highest frequencies but pre and post
ringing are equal, very short, and low in level.
Minimum Phase Slow Roll-o - Similar reduction in output level of the highest frequencies to Linear Phase
Slow Roll-o. No pre-ringing and very little post ringing.
