Default B4 and using different pair of monoblock

I would like to bi-amp my speakers using the B4 active crossover.

However, the two pairs of monoblocks have different gain - 26dB and 26.6dB. I believe the B4 can adjust gain levels - to a certain degree. However, does the B4 have enough resolution in its gain adjustment to be able equalize the gain on these two different monoblocks or do I need something else to do that upstream of the audio chain?

Thanks for your thoughts.

I certainly do not grieve, therefore, due to the 0.6 dB.

Drive the lows with the 26dB amp and the highs with the 20dB...you just might like it. Easy enough to try...

That's what I was intending to do with the B4. But I guess I can try it out tonight even without the B4 (and use the passive XO in the speakers) to see if the difference in gain is audible or will otherwise matter.

Well I tried it. Definitely need to attenuate the amps to the same level.
