The Luxman Laboratory Reference series had their debut in 1976.
Highlights of the first Real-Time Processed DC amplifier and the first Synthesizer Tuner.
Other components of the Laboratory Reference Series were the preamplifier 5C-50 and the power amplifier 5M-21, 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)
