Commentary
Compact size FM/AM tuner equipped with APR system.
It is equipped with a high-precision APR (Automatic Precision Reception) system to respond to any radio wave condition, and maintains optimum reception by controlling front-end gain according to radio wave conditions.
Automatic selection of RF-Mode (Local/DX) and High Blend (on/off) for excellent characteristics.
An in-phase transformer is adopted after the high-grade PLL detector to suppress digital signal interference and improve resolution.
It has built-in Route 3 and reservation timer for 2 programs of everyday/once/sleep, and it is possible to play the alarm clock and record the absence.
Equipped with 8 preset memories for each FM/AM and auto-tuning function.
