Your cart is empty. Warm Tips:
1. Two groups of speaker 1 and speaker 2 can output at the same time.
2. The VU meters will not work normally if the speaker output of the VU3Pro is not connected to the speakers. If you only want the VU meter function, please choose the mic input.
3. Do not connect the VU3PRO to amplifiers whose actual output power is greater than 350W, otherwise the VU meters may be damaged.

I really wanted to like this, it’s really a nice looking, and well built piece of equipment. It also has the features I was looking for. My biggest complaint is the needles only move when the mic is turned on, even though it has speaker connections. The speakers passing through this does absolutely nothing as far as making the needles move. I bought this for my surround sound just for looks, but if you have a tv stand like I do, where the receiver is underneath the tv you have to turn it up really loud, so the mic will pick up noise. Since I watch tv with my surround sound on, the needles don’t move because the volume doesn’t register through the mic due towhere it’s placed on top of my receiver. If I play music it has to be turned up really loud and even then there is a delay with the needles which bothers me.If it worked like I thought it did, passing through and picking up the sound signal, I would have kept it. It just didn’t work for my setup.

I like it although I wish it had a on/off switch since it's always on if it's plugged.

There is a minimal but noticeable brightness difference between the meters. In color cycle mode I see blue/purple I would like to use constantly however can not be selected manually. The frame is warped by .6 mm so it wobbles. I turned it upside down and it does the same thing so it's not one of the feet that is different. I have tested it on several flat surfaces to be shur it is the unit. I will be adding a washer under one rubber foot to fix that. All the switching functions are working well. All metal face plate and knobs are a big plus. I have 12 sets of vintage speakers and 9 vintage amps and receivers that will be switched in and out of systems. This switcher comes in handy for many comparisons to decide which ones to keep and which to sell.

I sold audio in the early 1980s. Really nice VU meters were on all of the high-end amplifiers. At that time, I could never afford those fancy amplifiers. As audio manufacturers, (and audio customers), no longer see the value in VU meters, VU meters have fallen away from customer desirably. Pity! I added the Douk Audio VU3 PRO Dual Analog VU Meter for purely nostalgic reasons. I really like these VU meters.
