Commentary
This is a stereo tuner amplifier that became a huge hit with 300000 units in Europe and America due to its high cost performance.
In order to ensure the freedom of sound quality design, the power amplifier section is composed of all discrete circuits without using power ICs, and sound quality measures developed by Integra are introduced.
A highly stable power amplifier has been realized by adopting a feedback type constant current amplifier stage for the power section input.
It uses a classified memory that can divide the desired FM/AM station into 6 groups A to F.
Up to 40 stations can be registered in each class, and overlapping stations are also possible.
It is equipped with an APR (Automatic Precision Reception) system that automatically switches between sensitivity (RF-DX/LOCAL) and stereo mode according to the radio wave condition of FM broadcasting, and performs optimum reception.
Equipped with an auto-search tuning function, it is possible to perform auto-tuning that automatically scans by pressing the UP/DOWN keys and temporarily stops when receiving a broadcast station.
It comes with a system remote control and can be operated in combination with C-303, K-W505, K-503R, etc.
