Commentary
Component system with full acoustic design.
Receiver section
A full-scale monolithic IC is used for the amplifier circuit, constituting an amplifier circuit with less noise.
The circuit uses an ITL-OTL-OCL circuit without an output capacitor. By connecting the amplifier and speaker directly, distortion in the low frequency range, frequency characteristics and damping characteristics are greatly improved.
The preamp section and main amplifier section can be used independently, and a multi-amplifier configuration can be developed by adding a multi-channel divider, etc.
The FM tuner uses a 4-pole MOS-type FET (27 patents worldwide and in Japan).
Player part
A 30 cm aluminum die-cast turntable is used for the turntable, and together with the belt drive system, the wow flutter is minimized.
The tone arm uses a pipe arm with an inside for scan seller.
A MM type cartridge is used.
Speaker part
2-way configuration is adopted.
It has a 16 cm cone woofer in the low range and a 5 cm horn tweeter in the high range.
