LUXKIT A704
¥ 12,000 (a set of two cars, around 1982)
Commentary
Small speaker system kit with built-in amplifier.
Newly developed 8 cm cone type full-range unit is used for the unit.
This unit is designed exclusively for A704 and uses a large ferrite magnet in the magnetic circuit.
The amplifier circuit uses a multi-loop NFB that combines voltage feedback and current feedback.
In order to take advantage of the fact that the amplifier and the speaker are integrated, the speaker is also incorporated into the NFB circuit of the amplifier to control the system comprehensively.
The high-frequency sound pressure can be adjusted in 3 levels.
The adjustment amount can be switched between Normal, Hard (+ 3 db) and Soft (-3dB) for a sound pressure of 10 kHz.
The enclosure is sealed and high-density chipboards for sound are used to eliminate box sounds.
The power supply can be selected from AC100V or DC12V at the time of assembly.
When set to 12 VDC, it can be used as a battery power source or battery type.
Can be mounted on separately sold Acrylic Stand SD701.
