The amp I just bought to drive the bass units on Gumby has an input sensitivity switch marked
0.77V / 26dB / 1.44V.

The input is unbalanced from the Bryston 1B main out via a simple 12dB active x-o.

Does anyone know what setting I should be using???

Sounds like what's found on Crown amplifiers...

The unbalanced output is consumer level then, 0.77v, so set your amp to this. If it were balanced you would have twice the signal level, or 1.44v. This input sensitivity is the signal level required to drive the amp to full rated output.
