Hello everyone, I used to use the DDRC-24 produced by minidsp, but the function of DDRC-24 is only room acoustic correction, lack of streaming media function and HDMI audio input, so I considered upgrading the equipment. After collecting enough information, I set my target on NAD M10 and lyngdorf TDAI-1120, because I already have Dirac live products, and many users think that room perfect is better than Dirac live, so I bought TDAI-1120 .
Let me introduce my equipment first, my speaker is Tannoy gold7, connected to the digital output interface of TDAI-1120. As soon as I connected it, I found that the speaker had a significant noise floor, but when this box was connected to the DDRC-24, the noise floor was basically not audible. Here to explain, because Tannoy GOLD7 only has XLR interface, DDRC-24 only has RCA output interface, so I use RAC to XLR audio cable. When this audio cable is connected to DDRC-24, it has low noise and very low noise. Must be close to the speaker unit to hear. But when TDAI-1120 is connected, it can be heard more than 1 meter away from the speaker, especially when the room is quiet, the noise floor is obvious. Of course, when playing audio, even if there is a noise floor, it is not audible, but this will have a negative impact on the transparency of the sound quality.
In order to test whether it is the TDAI-1120 problem or the cable problem, I found another RCA to RCA cable to connect the TDA-1120 to the RCA interface of Genelec M030, and found that the noise floor is very small, indicating that it should not be the problem of TDAI-1120, The problem is that of the RCA to XLR cable.But what I don't understand is why this RCA to XLR cable connected to DDCR-24 has no obvious noise floor.
Question 2, I have completed the measurement steps of the room perfect. I have measured 8 times in total, and the room knowledge has reached 99%. After turning on RP, compared with DDRC-24, TDAI-1120's sound field and low-frequency dive are indeed better, music and movies are more atmospheric, However, I feel that there are too many low-frequency volume and some medium and high frequency,not up to expectations . I have seen a lot of comparative reviews between Dirac and RP before. Many users say that RP's low-frequency control is significantly better than Dirac, allowing speakers to play more low frequencies. The performance of RP on my speaker system is indeed the same. But a new problem appeared. After the RP was turned on, I feel that the low frequency volume feels a little bit more, and the low frequency is not clear enough.I wonder if Dirac's low-frequency control is not good enough, resulting in less low-frequency sense before. In contrast, room perfect's low-frequency sense is too much? Or is my room perfect measurement not done well? Users of TDAI-1120, do you feel that there is too much low frequency after RP is turned on?
Question 3, when I watched the movie "Nobody.2021", in some scenes, the sound lost the off box feeling. It was obvious that the sound came from the left or right speaker. I don't know if it's due to the poor quality of video files,because when I was playing the remux version of "The great showman.2017", I didn’t find the sound to lose the off box feeling. I’m trying to download the remux version of "Nobody.2021" Let's continue to verify this problem.
