The product has a rated power (RMS) of 200 watts. The satellite speakers each deliver 35 watts RMS, the subwoofer 130 watts RMS. The specifications are based on the internal product data.
Because 400W is only the peak power, i.e. for one second or milliseconds the unit can consume 400W and otherwise ehr 200W, see manufacturer website: Technical data: https://www.logitech.com/de-at/products/speakers/z625-gaming-speakers.980-001256.html
I doubt whether you can order only that, but you can at most look for spare parts on ebay or something. But I would advise you to unscrew the box first and see if it's not just because the cables no longer have contact.
Otherwise write to the Logitech or Galaxus support, only users will answer you here.
The price can change on a daily basis, as described here: https://www.digitec.ch/de/wiki/6028. Only one price can be shown per day on the price graph (if there are several, the lowest one is shown).
Yes, it should work.
I use 'Line In' for the PC and the 'Digital optical' connection for the PS4. Theoretically, you can also connect more, as long as there is still a connection.
The sound is similar and only gets better with Multiroom or large distances. For a normal living room (20-30m2), this does not play a noticeable role. But it is not disturbing and is ready for future expansion.
Quote from the product description: " The system supports multiple inputs, including 3.5 mm and cinch. Up to three compatible devices - such as a game console, a TV and a computer - can be connected simultaneously. No plugging is required to change audio sources.".
Hello Jan_1893
The Logitech Z625 is controlled via a stereo jack plug 3.5 mm. There is also a stereo input with cinch Li + Re for the TV input. I have connected the Z625 to my PC, the sound is not bad, but I don't expect a perfect Hi Fi sound. With what you're doing, I would go for real speakers if the budget allows it. The prices for good speakers will be around CHF 1000. For high-end speakers (PIEGA Switzerland) the price level is certainly much higher. What you have to know is that the loudspeaker is the most important part of a music system and you should not save money here. It is better to save money beforehand and then enjoy the high tones with the great system. I know your questions have not been answered, but you could get the right answers from Pioneer and Logitech support. Best regards Eggi.
I have connected the PC via optical cable to the main inputs on the subwoofer and also connected an old smartphone to the headphone input on the right speaker. When both devices deliver a signal, both can be heard at the same time.
I also connected the PC via 3.5 mm to the inputs on the subwoofer. In my case, however, the optical and 3.5 mm outputs appear as separate devices in Windows, so that I cannot use both at the same time due to the software. In this case, I have to switch between them in Windows.
