"I am currently using QSC amp. The model is RMX 850 and they require input level of 1.5V to reach their full power."

This is a typical value for an input signal to drive a power amp to full power. The 950 will work fine with this.

This means that a voltage sine wave with an RMS value of 1.5V will drive the amplifier to full rated output power into the specified impedance. A signal source to this amp that can supply 6.3Vrms will have no problem driving the QSC amp to full power. This does NOT mean that the source will overdrive the amp UNLESS you turn up the volume way too high. The 6.3V is a maximum rating.

An analogy, my Ferrari (which exists in my dreams) has an engine rated at 500 horsepower. When I move it from one end of my garage (which also exists in my dreams) to the other, a distance of 100 yards, the engine only uses, maybe 50 horsepower max. This is controlled by the Ferrari's volume control ... oops ... gas pedal.

"If it is 6.3V per channel, Does that mean I will get 44.1 V total from 950 if all channels are used. Is that correct? I don't understand this very well and hope you can guide me."

Yes, it is 6.3v (rms) per channel. Combinging, as you did, to get 44.1 V total is meaningless. Deal with each channel one att a time. You have 6.3 v at each of the 6 outputs. This is a rated maximum voltage. If you are putting in a very small signal, even with the volume control all the way up, you will get out much less than 6.3 volts at each channel.

"Was that signal peak or RMS? Let me know what you think, Paul."

Which signal are you refering to?
