Is the B2 Bass Module Compatible with the L1® Classic or Model I
Here is the official answer from Bose
Question: Is the L1® Model I and Classic compatible with the B2 Bass Module?
Answer: Yes. When using the B2 with the L1® Model I or L1 Classic systems, please note that the rear panel switch must be in the “Normal” position. If selected to the + or - switch positions, it will not work, resulting in muted audio.
Unofficial FAQ Extension:
It says that it will only work in the Normal setting
If you have a Classic, you will get sound in all three settings, but only Normal is supported. more details ...
What does the B2 Bass Level Switch Do?
The B2 bass module includes a switch allowing you to select the appropriate level of bass output for your application.
There are three settings:
|+||Bass voicing designed for DJ/Music playback applications|
|Normal||Bass voicing ideal for bass guitar or live sound application when mic'ing a kick drum|
|-||Bass voicing which is perfect for acoustic guitar and vocal|
Attention L1 Model II users: In order to take advantage of the B2 rear panel bass level features you must upgrade your power stand firmware to version 1.4 or higher. If your power stand firmware is not current, the rear panel switch must be in the Normal position. + or - switch positions will not work.
For the latest firmware see: L1® Model II Power Stand Firmware Updates (or see section immediately below).
Attention L1 model I and Classic users: When using the B2 with the L1 model I or Classic systems the rear panel switch must be in the Normal position. + or - switch positions will not work.
Note: the B2 Bass Level Switch does not change the functioning of the B2. It triggers switching at the Power Stand to which it is attached, if that Power Stand is a Model 1S or Model II with firmware version 1.4 or later.
Why doesn't the B2 Bass Level Switch work with the Classic / Model I?
The Classic/Model I is capable of recognizing four distinct scenarios based on what is connected to it:
- No B1 (this is detected at the Bass Module Output)
- One B1(this is detected at the Bass Module Output)
- Two B1s(this is detected at the Bass Module Output)
- Four B1s (this is detected using an PackLite® power amplifier Model A1. This last scenario is recognized by a combination of triggers (number of B1s conneted to the Bass Module Output AND something connected to the Base Line Out).
The Classic / Model I doesn't have a pre-programmed bass setting for EQ and level that directly matches the B2 Bass Level Switch in the + position. You get similar outcomes using the R1 Remote, but this is nothing built-in to the Classic / Model I that can do that for you automatically, so it cannot respond to a change in the B2 Bass Level Switch.
Before the release of the L1® Model 1S, only the Classic/Model I had switchable ToneMatch® Presets. The Compact has a built-in Preset for vocal microphones, but you cannot turn that off or change to a different Preset. The Compact also has a built-in Preset for Acoustic Guitar. You can turn that off, but you cannot change the Preset, nor can you change to a different Preset.
Similar to Presets the Classic / Model I and Model II all had different EQ settings built-in to support the B1s. You could not change these except by adding or removing B1s . That is a very important thing to note, you could only change how the EQ settings were being applied by changing the number of B1s attached.
The Model 1S and Model II (with firmware version 1.4 or greater) have EQ settings (similar to Presets) that affect the Power Stand Bass Module Out and the Bass Line Out. With the previous models the only way to activate different EQ settings was by changing the number of B1 connected to the Base Module Out.
The B2 Bass Level Switch allows you to swap out different EQ settings without having to add or remove B1.
On the Classic / Model I, there are built-in Presets, but you have to use the Preset selector on the Power Stand to access these. There is no update to allow the B2 Bass Level Switch to change bass EQ settings on the Classic / Model I.
You get sound even though it says it will mute
On the L1® Classic, you may get sound regardless of the position of the B2 Bass Level Switch. Leave the switch setting at Normal.
The - setting is probably running without the Bose B1 EQ optimization and WITHOUT the system limiter or speaker protection. This may not cause any harm, but there is no reason to do it.
The + setting is probably going to give you the same sound as the Normal setting.
So is the B2 Compatible with the Classic / Model I?
Yes. However the B2 Bass Level Switch cannot change the EQ settings or Presets on the Classic / Model I.
You can tailor the sound of the B2 by using the Presets in the Power Stand and by using the R1 Remote Tone Controls.
