You need set UAC 1.0 Mode. See my review. The UAC 1.0 mode provides microphone support with a fixed PCM 48kHz-16bit output and is practically compatible with everything. The second mode, called UAC 2.0, enables higher-quality audio via USB, up to 384kHz-32bit and DSD256, but requires specific...

Hi! I have the same amplifier and have been using it for about two years without any problems. I remember that at the beginning it had a slight hum, which I managed to fix by replacing the speaker cables. I recommend checking the RCA connections and also the cable connected to your source (if...

Frankly, a casing for Fosi Audio amplifiers seems absolutely pointless to me. These amplifiers are already designed to be compact and well-built, and their clean, modern look with quality materials is part of their appeal. Adding an external enclosure would only make heat dissipation worse...

Hi, I’ve opened the ZA3 several times and there shouldn’t be anything inside that causes the rattling. If it works perfectly, I recommend opening it up and taking a look. It’s a very simple operation to do. There are no seals, and if you follow the instructions shown in the many videos that...

The main purpose would be to connect two pairs of speakers that operate separately but in sync, for example, front and rear speakers to achieve a greater and perfectly controllable effect. This solution would also allow use in two different rooms, easily and without additional costs, creating a...

In this specific context, creating a system that allows both amplifiers to play simultaneously would make it possible to connect two pairs of speakers that operate separately but in sync — for example, combining front and rear speakers to achieve a wider effect in larger spaces. This would be...

Yes, an option that includes a built-in preamplifier which allows both amplifiers to play simultaneously.

In my opinion, the best option is the second one: adding another DC input port to allow switching between the internal power supply and an external one. This way, it's possible to choose between the standard or an external linear power supply depending on the need. I believe the first option...

After careful consideration, I have to admit that the idea of installing USB sockets is indeed very useful and an excellent idea, especially for powering external devices such as the SK01 or the AH01A LED.

I would keep the excellent warm vintage light used in the LC30, rather than the white one shown in the photo.

If the SUB RCA output is affected by the volume and tone controls of the main output (even if it's stereo), it creates a dependency that limits the flexibility of the system. In practice, it becomes difficult to manage a second pair of speakers independently using a preamp such as the P3 or P4...

I'm referring to a direct line output, optionally equipped with a sensitivity control separate from main output, to allow connection to a second amplifier, with in turn makes it possible to connect two additional speakers to be strategically placed in a room. Basically, for someone who has, for...

Charlese, I would like the project to include a trasparent line out, not affected by volume control or other active stages, to which I could connect a second independent amplifier. This would allow me to eventually add another pair of speakers in strategic positions within my setup, providing...

Surely this is due to particular personal needs, for example I tried to play with discord and world of warcraft and it didn't give me any problems, I keep the two volumes, the game and the chat, separate, which is what interests me. What game do you have problems with?

For the record, I should inform you that my Mac also does this with my Apollo Twin professional sound card that costs over $1000. So I don't think it's a defect of the K7.
