L1® Classic
This is the name now used to describe the L1 in the Bose® Personalized Amplification System™ family of products.
Introduced in 2003, this remained in production until 2007 when the L1 Model I was introduced. Visually and audibly, almost identical, the main differences were:
- Identified by orange labels and L1™ logo
- Simpler output panel (dropped Amp 1 out, Amp 2 out)
- RoHS ("the restriction of the use of certain hazardous substances in electrical and electronic equipment") compliant.
