Fun Generation RTA-31

I bought this as a centerpiece for my production desk after having seen it in a TechMoan video - and it does exactly what I want it to do, i.e. react in a visually pleasing manner to my audio.

Some things to note:
The unit is passive and audio still passes through when turned off.

XLR in and out are linked as are RCA in and out. No summing of the two signals takes place, which might be exactly what you want. I use balanced audio from my interface and RCA from my record player so I thought this might save me a connection point -- it does not. Not a big deal, but worth mentioning.

With my studio monitors at unity gain I was not able to have this unit display well at a comfortable listening level, even with sensitivity turned all the way up - I had to have my interface output quite high. This was easily solved by lowering the input gain on my monitors.

Overally this is a solidly constructed rack unit and it's lots of fun to look at, but I wouldn't use it to make any mixing decisions.

I am very happy with this purchase - other than I had to hot wire the plug to make it work since I did not receive a US power cable. Now I have to find a US power cable that will work with it. 4 stars, since I am very disappointed that I did not receive a US power cable, or an adaptor that will work for US.

The display is bright and great fun to watch. Brightness knob is a great option since the green LEDs are very bright. I ran a frequency sweep into the unit and the LEDs respond as they should for each frequency. A couple comments: I would change is to add a couple yellow LEDs below the top red LED, in each frequency set, this would improve the appearance greatly and would let you know the signal is close to the top LED value. Also, I would include a way to adjust the display decay speed. Oh yes, and an option to add a peak hold that displays for a short time.
