SPEC RMP-UB1/RMP-UB1SFP

What is the DIRETTA

Diretta is a new audio transmission technology over LAN (network line). This technology aims to improve sound quality by keeping the load on the receiver constant, with the sending side of the sound source as the “host” and the receiving side as the “target”. A great effect of improving sound quality can be obtained when playing a high-resolution sound source with a USB-DAC. In order to realize diretta, host and target are required.

Noise can be reduced by continuously sending a small amount of data rather than processing a large amount of data intermittently. DIRETTA ON RMP-UB1 reduces the impact of digital signal processing on analog signals, mainly in DAC devices, by averaging the data sent to the USB DAC. This improves the dynamic SN.
RMP-UB1 is not a noise filter. By improving the dynamic SN of the system, the original timbre expression emerges.
This greatly contributes to the SPEC philosophy of “realistic reproduction,” and brings out the reality of live performances.
