Thank you. I have read that 2v is probably okay as that is what CD players output. But then I have also read completely different advice. So it's very confusing for me.
Okay, thank you for this. I guess I will have to experiment. I assumed there was some sort of setting formula commensurate with the amp's input sensitivity.
I will keep this in mind. Thank you again.
wow, next project! No ultra and and sub (yet) but great idea!Here is the approach I took with my vintage receiver (Pioneer SX-1250). I separated the power amplifier from the pre-amplifier (jumper removal) and connected my WiiM Ultra line out (set to variable output with volume at 0) to the power amp in. Then I connected from the last monitor point in the receiver (Adapter Out on the SX-1250) to the WiiM line input. This effectively eliminates the active part of the Pioneer pre-amp along with all of the controls such as volume, balance, muting and filters while still allowing for access to the tuner, turntables, CD player and tape decks. Source selection on the receiver functions normally. The only thing I'm losing with this configuration is noise.
I usually don't use tone controls or loudness but that functionality is available in the Home app if desired. An additional bonus of the variable output on WiiM is the availability of bass management if you have an Ultra and are using a subwoofer (which I am). Plus, there is also the added convenience of being able to control the volume using the remote.
I just want to reiterate that you should change the WiiM to variable output with the volume set to 0 before connecting to the receiver's power amp to prevent any unfortunate accidents.
Can you explain more about this variable output setting please? What is the benefit, and does the WiiM Pro Plus also have this?
The setting is under the "Audio Settings" > "Fixed Volume Output". When this setting is turned off, the volume can be varied using the Home app or the Bluetooth remote. When "Fixed Audio Output" is turned on, the volume will be fixed at 100. When using the WiiM as a pre-amp feeding a power amp, you want variable output to control the volume. All of the WiiM streamers share this feature including the Pro Plus.
Ah, I see. I thought there was a separate variable output setting. I hadn't realised you were referring to the volume dettings. Many thanks for the clarification.
What I have read so far on different sites is that it is generally advised to limit the volume level at the last possible device of the device chain before the speakers. Given the BT20A is an integrated amp it would then make sense to limit maximum volume using the volume wheel of the Amp and not in the Preamp. However, you are right that this approach creates the danger of children playing with the volume knob which could damage the speakers.
Yes, I have seen this suggested as well. Children accessing the BT20A is extremely unlikely in our situation, but the possibility is worth being mindful off. So in this scenario you would use the 2v output?
If it is extremely unlikely, then I would use 2V output of the WiiM and leave the volume wheel of the BT20A at the position of your maximum tolerable level. And then better put the BT20A in the back of the shelf or inside a cupboard, as you never have to access it.
What is your current setup?
I know you are getting conflicting info, but I reckon the bt20a will perform at its best if its volume is at full because that's when it degrades the signal the least (remember my contact on the far left, "on top of the music" analogy in a PM?).
Yes, and thank you so much. I'm afraid I get myself very confused with all if this, so I'm hoping it will end up being a simple process when the WiiM Pro Plus arrives and I attempt to set it up. I'm hoping it will come Thursday or Friday. I wasn't aware that I need to change all the settings for each input source. For my situation, this will be the CD player connected to the WiiM's Optical In, Chromecast and Airplay Audio, and Bluetooth Audio. I will connect to the amp via RCA cables.
Yes, it's somewhat confusing, but I am extremely grateful for any additional info to help me get my head around this seemingly complex setup process. Interestingly, there doesn't seem to a standard or default line level output setting, and if I'm understanding correctly, it's more of a trial and error situation. I have lots to digest, but I'm sure it will all become clear once I have the WiiM and the App here.
Over my head I'm afraid. I had no idea setting up a WiiM was so complicated.
Sorry for confusing you. It is no problem to just follow the advice by @Wiimer and @harkpabst. The music will probably sound the same. But you will have to take care that none of your visitors accidentally connects to the bluetooth input of the BT20A to play his music. That will lead to a loud surprise.
Yes, if you no longer need Bluetooth on the BT20A, you may want to remove pairing with all devices connected to the BT20A and remove the BT20A antenna.
In general, the volume differences of the different inputs are not that huge. If you have problems with the difference you can adjust it. but you do not have to.Over my head I'm afraid. I had no idea setting up a WiiM was so complicated.
In fact, it is not difficult. Don't worry.Over my head I'm afraid. I had no idea setting up a WiiM was so complicated.
And I cannot tell you how grateful I am for that. Thank you.
... stems from. It's not entirely wrong, but maybe still a bit of a misconception. You cannot feed a voltage higher than the input sensitivity into any device without violating rule 1. So, this ...
... is basically just a slightly complicated way to ensure that the amp's input stage is not overloaded . We can probably agree on something like: Keep the signal level high, but not higher than natively supported by the next stage.
Good hint. Also depends on the volume setting on the phone, of course.
Actually, it isn't. Sticking with the defaults is OK.I had no idea setting up a WiiM was so complicated.
