Analog Audio Processors
Sound Processors with Built-in Surround Sound Function
BD3490FV
●General Description
Built in stereo 4 input selectors and volume that there is not an impedance change of a volume terminal. And this is sound processor can realize 2-band equalizer (bass/treble, gain±14dB / 2dB_step) and bass-boost,
output-gain, surround by external components.
●Features Built in stereo 4 input selectors (single end). Built-in input gain controller for volume of a portable audio input. When the volume setting exchanging, it can use a volume input terminal as a microphone input terminal because there is not an impedance change of a volume input terminal. Bi-CMOS process is suitable for the design of low current and low energy.
