TS-VU003 driver board for VU meters

[kifeep]

I've been think about adding some eye candy VU meters using one of these TS-VU003 boards:

TS-VU003 Vumeter Controller LED / Lamp

This TS-VU003 VU meter control module lets you integrate magnificent VU meters (sold separately) into your DIY audio creations, whether backlit by LED or bulb.

The idea would be to just split a couple RCA outputs on my miniDSP, with one leg going to the amp as normal and the other leg feeding a meter.

I've read a few reviews of speaker-level switchers/meters (which are obviously a different category), but some of the comments have suggested that line-level meters would be more likely to degrade audio.

I can't find any measurements of the driver board, but based on the limited information available does this seem more likely or unlikely to introduce noise into the audio signal?

Also, if anyone has experience with these, I would be grateful to hear about your experience.

Thanks in advance.

Although quite belated, today I just came cross with this thread.

It looks that this VU-amp board can be used for line-level signal and SP-high-level-signal by adjusting the dip selectors;

I have built my DIY-ed IEC 60268-17 ballistic compatible 12-VU-Meter Array (ref. here #535 in my project thread) where I use six (6) sets of similar VU-amp module (board) which accepts only line-level stereo signals. I inserted High-to-Low Convertors, therefore, for VU monitoring of SP-high-level signals of amplifiers.

I do not know, however, whether this TS-VU003 board would enable IEC 60268-17 ballistic behavior compatibility to your specific selected (to be selected) physical meter module, or not.
