Summary: This Product works as described. I had a PA speaker with 1000 watt Amp, this was the missing link to the system. Before it was very quite and unclear with zero control, now the system is perfect. Also simplest system to use with single output that I could find.
Summary: One year ago, I purchased a Pioneer SX-1250 receiver and had it re-capped and the controls cleaned. Now, the balance control is getting noisy again. Enough! Time to look for a pre-amp. This unit does everything asked of it. The controls have a good feel. Looks good.
Summary: nice sound to it defnitely add a bit of extra power for my system which i needed..it is also very helpful to me not only i get save me the trip of adjust my pyramid pa 305 and sony 7.1 recievers...now all i need to do is adjust this unit volume it raises or lower the volume...
Summary: When I purchased and received this unit, there was an issue with the volume knob, where it would scratch (IE, static would play over the speakers) as you change the volume, and it would cause all the sound to drift further to the left channel as you turn up the volume over 80%.
