CAUTIONS:
• DO NOT connect any bass module other than the B2 or the B1 to the power stand.
• Use only the supplied B2 bass module 4-wire cable to connect the B2 bass module to the
power stand. The power stand uses the signals on two of the wires to automatically sense
the state of the B2 bass module. DO NOT substitute the supplied cable with a 2-wire
speaker cable.
Connecting a second B2 bass module (L1®model II system only)
Using a PackLite power amplifier model A1 allows you to add one additional B2 module to
your L1 model II system. Refer to the A1 Owner's Guide for detailed operating instructions.
1. Make sure the A1 amplifier power switch is OFF.
2. Plug one end of the supplied ¼" TRS cable into the Bass-Line Out connector on the
power stand. Plug the other end into the INPUT connector on the A1 amplifier.
3. Connect a B2 bass module cable from the OUTPUT connector on the A1 to a B2 bass
module.
4. Plug one end of the AC power cord into the A1 amplifier and plug the other end into an
AC (mains) outlet.
5. Switch the A1 power switch to ON (I).

slide. For added stability and protection, detach the included self-adhesive rubber feet and
attach them to the loudspeaker in the four recesses (as shown in Figure 6). When using the
loudspeaker, keep the rubber feet in contact with the floor.
