My most recommended audio equipment right now
Since I primarily wanted to use the Duo for mixing via the line input, this rack-mounted Duo was the perfect product. Building the DIY kit was also a valuable learning experience, and deepening my understanding of outboard gear was extremely valuable.
In fact, after I finished building the first unit, I discovered a rare issue with the RED switch on one of the PCB boards, but Peterson kindly addressed the issue and I was able to complete it 100%.
I use a power distributor to manage the power for my outboard gear, but there are times when I want to be able to switch the power on/off on this Duo itself, so if further improvements are made, I would like to see a power on/off feature on the front panel. (I want to take good care of this equipment, so I want to avoid unnecessary power consumption on the circuit components.)
However, this product's stepped potentiometers allow for stereo use, and the three serial Color modules allow for a wide range of experimentation. I highly recommend this product for discovering new things.
