BenAriel I have dudu7 and just upgraded my car system with speakers, and subwoofer, amp, and DSP. and I asked the guy that installed it for me if he used the SPDIF from the amp to HU he said that he used RCA because I wont feel any different from this HU SPDIF and if I want good quality with SPDIF I should buy DAP (Digital Audio Player) is it true with the DUDU7 ?
gismo BenAriel no, he is simply lazy or wants to sell stuff he has on the shelf. Essentially he just says "good enough for you, go away".
dudu-langzi gismo This is not necessarily, RCA analog output is a good way, but it is vulnerable to interference, not suitable for long distance, if the DSP is in the trunk, then you can choose optical output, because it has a strong anti-interference ability.
BenAriel dudu-langzi hey when I use the optical connection the sound is really low, is there any way to increase it ?
