Hi
For a channel feeding 10K resistors to the bus, increasing to 14K3 is about 3dB reduction in level so should work fine.
Of course it is being considered balanced here so it is actually 20K normally with 28K6 when 'panned centre'.
Of course the are other discussions as to whether it should even be -3dB at centre or -6dB. Some go for a compromise at 4.5dB. The argument follows that the sound pressure level should remain constant which is not necessarily the same as constant power being emitted by the loudspeakers.
The formulas are simple maths excercises but you do need to have appreciation of 'log' powers.
