Luxman M-03 @ +/-81VDC rails and uses nice Sanken outputs on a decent heat sink.
This is the amp that I bottomed out a Matrix 801 woofer and damaged it from so much power.
I still don't get it why this device won't be good enough for people who just want swinging needle meters and why another one needs to be created from scratch. It already exists, looks nice is rather cheap and works fine.
Just don't run the speakers through the VU3.
Just connect the tested Douk VU3 in parallel to your speakers (at the amp side) and no need to look any further. There is no sound 'degradation' in this case and you are ready for $ 150.-
If I didn't already have meters (don't use them) I might even buy it.
It works, however it is so small and low weight that it is unable to stay firm and not to turn over because of weight of XLRs and cables. Again not practical and finished in a garbage box.
Yes but ….
1) the relays used are low current devices
2) small binding posts with close spacing do not allow me to use my big latching banana connectors that prevent from contact resistance issue.
So, even if I considered buying it re price, I would not because it is not practical to me.
I already have an experience with their 3 to 1 XLR switch. It works, however it is so small and low weight that it is unable to stay firm and not to turn over because of weight of XLRs and cables. Again not practical and finished in a garbage box. All these cheap purchases are in fact expensive.
If you cannot plug or unplug a 1/4" headphone plug, RCA plug, or banana plug into the product without it moving (and without having to hold it still) it's just toy HiFi
I hope it's okay, but in my experience, sometimes the sound goes wrong when connected in parallel. (Apart from volume reduction)Just connect the tested Douk VU3 in parallel to your speakers (at the amp side) and no need to look any further. There is no sound 'degradation' in this case
How about displaying the average and peak voltage on some 7-segment LED displays? Could even be in amber yellow, Amir's favourite colour. Maybe have it update twice a second or something.

Agree. Even if they are not precise, they can still be dialed in so 0dB provides useful information, and they are cool to look at. They can signal you might damage something, or they can signal you are going into high distortion / crap sound territory.Find lots of these on ebay and other sites.

While I am fine with LEDs, most of the requests I get are for analog meters. There are inexpensive (unbalanced) driver boards for these too. Not sure how good they are, but usually based on TPA7318 or BA6138 chip.
Yes, many of these meters may be ”toys”, but many customers are just nostalgic and looking to set them to know when they are pushing amp to clip. Note the VU3 has a peak LED in the upper corner of the analog meter.

Oh, in the case of VU3, SINAD is only 3dB worse.
I was thinking about this set up from the same site - https://sound-au.com/project128.htmFind lots of these on ebay and other sites. Rod Elloitt has this posted… https://sound-au.com/project60.htm

Ok, ok, here's the second attempt:On @Helicopter's amp, the VU meters are backlit by the Hypex clipping indicators. Here is an early pic without the front bezel and handles...
