Review: Très bon commutateur, bon contact rapide avec le vendeur. Merci
Review: Ich habe mithilfe des Schalters mehrere Aux Quellen an meinen Streaming Verstärker angeschlossen, der nur ein Aux Eingang hat. Es funktioniert sehr gut; beim Umschalten zwischen den Quellen keine Geräusche und ich kann auch kein Übersprechen oder Brummen festzustellen. Ich denke auch die Wiedergabequalität hat nicht gelitten. Das Gerät ist sehr ordentlich verarbeitet und macht einen wertigen Eindruck. Ein kleiner Nachteil, das Gerät ist sehr leicht und wenn man hochwertige etwas steife Kabel anschließt, steht es nicht ganz so sicher.

## Questions & Answers

**Q: Will the 2 "out" lines work for "TV headphones" and regular speakers (with no amplification in between)?**
A: You do need an amplifier, unless your speakers and headphones are amplified already.

**Q: Does this device allow one to connect, say, 2 different CD players to the amp and switch indifferently between the two, one signal at a time?**
A: Yes.  If you read the other questions, the connection is explained. Any 4 RCA sources to one Amp or reversed such as single CD player to 4 different amps.

**Q: Will this work for car audio?**
A: I don't see why it wouldn't.

**Q: What is the maximum recommended cable length for the output, since it is passive?**
A: That’s hard to tell. Depends on your cable and your tolerance of signal degradation.

### ⭐⭐⭐⭐⭐ Review
*by G***I on 6 July 2021*

I managed to connect both my AVR (subwoofer single rca cable) and my stereo pre-amp (stereo rca cable) into inputs 1 and 2 respectively. Output stereo rca to my SVS PB2000 subwoofer. Now I have subwoofer for both stereo music playback and home theatre. Just need to toggle the selection between input 1 or 2. Does not seem to be any degradation of sound quality. Nice and tight bass sound.
