Audio Systems: 4 ohms voltage gain, load impedance, voltage gain

Question
Hello I was looking at the QSC GX3 amplifier and the voltage gain at 8 ohms is (32.2db)in decibels and (40.7x)in voltage gain  so what is this information at 4 ohms?

Answer
The same.  Voltage gain is the ratio of voltage out divided by voltage in.  The load impedance does not change the voltage gain, only the power gain!

Further comments:
For example, if the output voltage is 8vac and the load is 8 ohms the power output into the load is 8 squared over 8 ohms or 8 watts. If the load is 4 ohms the power out becomes 8 squared over 4 ohms or 16 watts.  If the load is removed the voltage remains the same and the output power is zero watts....  and so on.   Damping factor is the specification that tells how much or little the voltage changes with a change in load impedance.

Any more questions?
