The Luxman Laboratory Reference series had its debut in 1976.
Highlights were the first Real Time Processed DC amplifier and the first synthesizer tuner.
Other components of the Laboratory Reference Series were, in addition to the 5M-21 power amplifier, the 5G-12 Graphic Equalizer, the 5F-70 Parametric tone controller and the 5E-24 LED level indicator unit.
In 1977 and 1978, the Luxman Laboratory Reference series was expanded to include the following devices: The 5L-15 integrated amplifier, the 5M-20 power amplifier without VU meter as well as a cheaper tuner, the 5T-10 and the cassette Tape Deck 5K-50. The latter was probably purchased from a third-party manufacturer.
The functionality, performance and innovative design made the series unique and unmistakable.
Special features were:
- The world's first DC amplifier and synthesizer tuner
- Computer-controlled cassette deck
- Stackable components (the 4 device feet had corresponding recesses on the device below)
