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 Bass Module with the three position Bass Level Switch ( + Normal - ). Note: Support and behaviors for B1(s) is unchanged.
- 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.
- Note: If no bass modules are detected at the Bass Module Output the Bass Line Out EQ will be set to the B2 curve with the B2 switch set to Normal.

No cable plugged into the Bass Line out
| B2 Bass Modules connected | Output | EQ | Bass Signal Gain | Notes |
|---|---|---|---|---|
| 1 | 40Hz-200Hz | B2 specific EQ as set by the B2 Bass Level Switch ( + Normal - ) is present at the Bass Module Out and the Bass Line Out | Reference Level | There are three B2 EQ settings possible using the B2 Bass Level Switch ( + Normal - ) |
Cable connected to the Bass Line Out
| B2 Bass Modules connected | Output | EQ | Bass Signal Gain | Notes |
|---|---|---|---|---|
| 0 | 40Hz-200Hz | B2 EQ as though B2 attached and B2 Bass Level Switch set to Normal position | Reference Level | This presents the B2 EQ with the B2 Bass Level Switch set to the Normal position. (No resistance detected between the 2+ and 2- pins of an NL4 plug) |
| 1 | 40Hz-200Hz | B2 specific EQ as set by the B2 Bass Level Switch ( + Normal - ) is present at the Bass Module Out and the Bass Line Out |
Reference Level | If you are using a PackLite® power amplifier model A1 Extended Bass Package this is a total of two B2s (one on the A1 and one on the Power Stand) |
Powered Subwoofers
The Model II is an integrated system that supports Bose B1 and B2 bass modules. Connecting powered subwoofers to the Model II Power Stand Bass Line Out is not supported because EQ curves for the B1 or B2 are present at the Bass Line Out. This may or may not result in good results with a powered subwoofer.
If you want to use a powered subwoofer, connect your signal source to the subwoofer and connect the subwoofer high pass filter output to the L1® (any model).
