Douk VU3 VU Meter Review (Updated Version)

[solderdude]

It is just a sturdy switch and is probably better in contact pressure than your average power relay.

Thank you, will likely go with this option. Has anyone tested this switcher though?

Yes- I tested it after purchasing it. No real effect on frequency response or THD. Not sure what the isolation was between paths/ports, but it works well

So, if you just want a vu meter (without any switching functionality), and it doesn't
have speaker-level inputs, would using a line-out converter (as often used in car stereo
systems) in parallel with the speakers be the best way to avoid distortion - rather than
just using the line-level outputs?

Just split the input signal to the power amp. use a cheap low powe speaker amp to drive the swinging needles.
Just realize that the meters are just for the show.. just swinging needles

Yes, it is a practically useful and nice way especially if you (we) would like to monitor/correlate actual relative levels (i.e. tone balance) of air sound SPL given by multiple SP drivers directly and dedicatedly driven by multiple amplifiers; I completed my DIY of 12-VU-Meter Array based on this approach. If you would be interested please visit here post #535 on my project thread for the details. You can adjust the relative gain of such multiple VU meters by playing/listening to flat white noise (or pink noise).

How does the 12-VU-Meter Array behave during music listening?

By the way, in case if you would use VB-Audio Matrix as system-wide audio I/O routing center, the beautifully designed "peak meters" on VB-Matrix Routing Grid are also very nice for monitoring digital level gains in each of the I/O channels.

Very nice! The Audio-Technica AT-HLC-130
appears to be just a high-quality standard car impedance converter, for anyone looking for
something similar, the PAC SNI35 is a good readily-available substitute, (though only
rated for 20-20khz) that has been tested with no distortion at up to 2v output.

Guys at this price we are getting eye candy only.

I think I got peer-pressured [ADD: By uze'awl] and bought two of these at $1.99 each.

I positioned them under my left/right PC speakers.
You called them 'eye-candy' but they border the 'eye-sore' territory, after about 5 minutes of pulsations!

Maybe flip them around and have them as reflective mood lighting behind your monitor?
