Trying to match impedance

I am trying to match a pre amp with a power amp. My power amp has an input impedance of 1.2K ohm balanced and 50K ohm unbalanced. My question is; how many ohms should the preamp's balanced and unbalanced output have in order to mate well with the power amp?.... and if the preamp and power amp were totally miss-matched, could you cause damage to either?

Thanks for your help.

Thanks for your help Mitch2.
The 1.2K ohm input impedance in balanced mode is correct according to the manual of the power amp.

Thanks for the info Montyx.
The input inpedances are correct, I have the manual in front of me.
The power amps I have are Threshold T-100 and T-200. The T-100 has the 1.2 K ohm input impedance in balanced mode and the T-200 has 2K while both have 50K unbalanced. T series Threshold amps were known for having extremely low input impedance in balanced mode.
Anyway, thanks guys, I see the picture.
