Douk Audio VU2PRO Needs Your Opinions!--The Upgraded Version of Douk Audio VU2.

Why is there a mic?

So you can see 'needles swing' even when it is not connected to any gear.

You could even do a shouting game with it... the one that can scream the needle to the highest value wins...

Why is there a mic?

At least for me, I do not need it!

I feel disheartened by how engineering resources can be wasted on gimmicky toys. For goodness' sake, as John suggests, why not just reuse what's already been invented?
It will be useful and might even be cheaper.

It will be useful and might even be cheaper.

Even though I share my dream VU/PK Meter concept here on this thread, I essentially agree with you.

And this is why I did my DIY building the 12-VU-Meter Array. Yes, it is a kind of "gimmicky toys", but "actually/practically useful" and enjoyable at least in my DSP-based multichannel multi-SP-driver multi-amplifier audio setup for monitoring at-a-glance multiple outputs of amplifiers using the same large-glass-face IEC 60268-17 compatible meters.

I like a giant, 6 foot version of that!

I'd just want the lexan circle with the ferofluid! Insert it into a speaker like a driver :-D

EDIT - NVM - exactly that can be had on amzn under 50 bucks!

Hello all ASR members,

Our VU2 RCA input selector with VU meters released in 2020, it's been over 4 years now. We are happy that many people have seen it and liked it, and we also received many suggestions.

Recently, our product department is going to update it in the appearance, size (will be larger and the same as our VU3PRO) and the functions..
Based on most feedback and suggestions from our users of the VU2, now we have two solutions.

Option A
Audio source: built-in MIC pickup, XLR*1, RCA*3, SPDIF*1
Working mode:
RCA--3-IN-1-OUT / 1-IN-3-OUT
XLR--1-IN-1-OUT
SPDIF--1-IN-1-OUT
View attachment 402435
Option B
Audio source: built-in MIC pickup, RCA*4, SPDIF*1
Working mode:
RCA--4-IN-1-OUT / 1-IN-4-OUT
SPDIF--1-IN-1-OUT
View attachment 402436

Note:
RCA, XLR and optical fiber are parallel input and output. No audio signal conversion function. In other words, the RCA output will only work when there is RCA input; the XLR output will only work when there is XLR input; the optical output will only work when there is optical input.

Introduction
3 knobs: adjust color, GAIN and sensitivity.The GAIN adjustment is only useful for the VU meter swing range and will not affect the sound quality.
Buttons:
The left one is to switch audio source among MIC, RCA, XLR (optional) and optical fiber.
The right 3 or 4 buttons are to switch RCA input or output.

Other Parameters:
Response frequency: 30Hz-20KHz
Backlight brightness adjustment: support (5 levels, can be turned off)
Backlight color adjustment: support (35 colors/marquee color)
VU meter gain adjustment: support (20 levels)
VU meter sensitivity adjustment: support (30 levels)
Remote control: support
RCA mute function: support
Settings saved after shutdown: support
Power interface: USB (Type-C)

The difference between the two options are with or without XLR input and output, please let me know your choice. Of course, other suggestions are also welcome! Thank you all!

This looks like a great improvement. When do you think it will become available?

Just for your possible interest and reference...

Yesterday I shared six new dancing video clips of my DIY-built 12-VU-Meter Array (IEC60268-17 compatible) together with all the on-screen Peak Meters of audio software tools while playing reference/sampler music tracks by JRiver MC, ADOBE Audition 3.0.1 and MusicScope 2.1.0;

____Part-1: using a typical reference/sampler music track suitable for high-Fq (treble) transient music sound

____Part-2: using a typical reference/sampler music track suitable for mainly checking and tuning of low Fq (bass) transient music sound as well as total tonality Fq-SPL balance all over 15 Hz to 22 kHz

According to some users' feedback, sometimes they may just want to put it near the speakers on the desktop...

Hi, we have designed a magnetic fluid display, but due to problems such as sealing, packaging and transportation, we have not officially released it. Engineers are still working on it and hope to improve it soon.

If you have any suggestions, please let me know, thank you!
