ET30 VU Meter Amplifier Speaker Selector Switch Box, 2 in 2 Out Vintage Switcher, with DB Panel Display & Remote Control, for Stereo Class A, B, AB, D, Tube Amps Home Audio Component

I originally wrote a review on here about this switch and was uncomplimentary (it didn't work, so it deserved it). I know I could have asked for a replacement from Amazon, but I couldn't be bothered.In due course the manufacturer read the review and got in touch directly with me. Firstly they attempted to diagnose the problem but to no avail. They then sent me another switch to test. It works fine.The switch is really a VU meter to show off alongside all your plain boxes. It not only does this, but you can change the light level and colour of the meters to match existing kit. You have the ability to alter the sensitivity of the needles and the speed of drop off (return to zero).An excellent bit of kit and excellent service from Neohipo. Needless to say my rating has been upped to reflect the current state.

Good little unit, happy with how it works. Doesn’t change the sound and makes it ideal for 2 amp or A and B speaker set ups

The unit has a USB-C socket for power but I found with my one at least the needles would move with no signal or the MIC input selected (Meters can work of ambient noise vis built in MIC or from the audio signals).Anyway, the meters seem to pick up noise from most USB power supplies and I finally ended up using a USB power supply designed to power Raspberry PI units (ones with USB-C connections).The unit seems to have relays in it to switch the signal and with no power connects Input "A" to output "1".

This is an outstanding product, brilliant VU meters which have 34 colours and 5 levels of brightness. The meters are adjustable for swing and sensitivity and there is a built in microphone if you do not want to connect an amp.There are multiple connections for 2 amps and 2 sets of speakers and a remote control to boot. All this for a very good price. An excellent product.

Have been umming and ahing about buying one of these, well isn't everybody? I first see the Douk Audio, but those are much smaller, then I found this one!Wow, it is much better than expected, solid build quality and functions as advertised. It's a great size, looks great and becomes a focal point.I would like to have seen phono and/or XLR for a more constant input than using speaker input/outputs, otherwise fantastic.Go on treat yourself, I did, no regrets.

This was good while it lastedIn fact it still works as a switch but the much-emphasised VU meters have stopped working less than 6 weeks after purchase.

works well with my two amps.

I think I have a faulty unit - makes a high pitch pop type sound when back from amp B to amp A. Not sure if it has any to do with one being. A tube amp (cayin) and the other being class a being class AB solid state (naim nait XS3)and A! This morning, I switched it on y only for a spark to flash in my Rack and now the unit is unresponsive with all its lights lit up . It’s going back.
