BH7779K Features
· An audio signal prosessing system IC that (Hi-Fi and normal audio) includes a peak-noise reduction (PNR) prosessor, an FM modulator / demodulator circuit, an input output switcher, an automatic FM detector circuit, an FM band-pass filter, a normalaudio circuit and a regulator circuit.
· Operates off dual ± power supply which allows a large reduction in the number of coupling capacitors required. A built-in regulator makes it easy to construct a power supply system.
· A built-in two-line serial control decoder circuit allows serial control of the internal mode settings.
· Four-input switcher (turner, BS, and line 1 and 2). The output switcher switches between STEREO / LEFT / RIGHT and Hi-Fi / MIX / NORMAL, and a BS monitor function is provided.
· The PNR processor and FM modulation / demodulation circuit povide reverse characteristics at recording and playback. Also, carrier frequency adjustment and FM de-emphasis / playback level adjustment have been combined.
· Built-in FM band-pass filter connects directly to the playback amplifier and excels at attenuation of the other channel. The FM recording output circuit has a high-performance high-frequency cutoff filter that produces a sine wave output.
· Switching noise is reduced by a slope-control type differential compensation circuit.
· Built-in envelope detector circuit and noise-detecting automatic FM detector circuit.
· Built-in normal-audio signal processing circuit that allows SP / LP / EP equalizer switching. Control terminal provided for use with the BA7755AF higi-voltage head switcher.
