DJ Pre II : Missin on and off button

I purchased this product to connect a turntable directly to a set of active speakers at home to listen to some vinyls from time to time. Small space so no point on having a mixer or something like that so thought this would be a good solution. Connection and quality is great, metal sturdy built and easy to connect. The transformer is a bit bigger than expected and I need an adapter for UK plugs so sometimes not very steady (depends on the adapter) but does its job. Only thing missing in this unit is probably an on and off button (or even turning off when volume is all out) as you need to actually unplug it from power to turn it off. Other than that, no problems with it just yet!
