Bass Line Out: Model II post firmware 1.4 with System EQ 1.04
September 2012
Bose released Model II Power Stand Model II firmware 1.4 with System EQ 1.04 to support the B2. This supports B1s in the same way, and it introduced new support for the B2 Bass Module with the three position Bass Level Switch.
The behavior of the bass line out with the B2 Bass Module Bass Module outputs on the Model 1S and Model II are based on the philosophy that adding B2 Bass Modules should give the user more bass output immediately. This changes the tonal balance as soon as you add a second B2 using an PackLite® power amplifier model A1 connected to the Bass Line Out. This is unlike the behaviour with B1 bass modules where the signal is attenuated as you add more B1s to maintain the tonal balance at lower volume levels.
No cable plugged into the Bass Line out
