The 1050 is basically a pre/pro with amplified channels. The 950 is just the pre/pro, no amplifiers. You need to supply the amplification for the number of channels you want to drive(up to 7)
There are a lot more differences between the two, which is why the 950/770(a 7 channel amplifier), will cost you over 5 times as much as the 1050. Hope that was clear!
