ALPINE/LUXMAN LE-117
¥ 38,000 (Released in September 1987)
Commentary
An equalizer amplifier designed for higher sound quality based on the concept of phono separation, in which phono amplifiers are made independent.
Among audio circuits, phono amplifiers handle particularly delicate signals, so circuit design must be taken into consideration.
Although thin, the LE 117 allows for a wide chassis space, allowing for a loose circuit design.
3-step gain switching and 3-step impedance switching are available for various cartridges in Japan and overseas.
The amplifier circuit uses a high-gain equalizer that can simplify the signal system and matches cartridges such as MC, MM, and IM.
The S. T. A. R. circuit is used to supply power directly to each stage without sharing power supply lines or earth lines.
As a result, the S/N of the auditory sense is improved.
