Sound Processors for BOOM BOX / Mini-ponent Stereo Single Power Supply Sound Processors with Built-in Pre Amplifier for Tape Recording and Play Back (With Integrated 2-/3- band Equalizer) BD3401KS2,BD3402KS2 No.10086EAT03 - Description The Sound Processor with built-in record/play functions for cassette players, is suited for sound quality products such as, BOOM BOX, mini- and micro-audio systems. It incorporates various functions ranging from audio source selectors to preamplifiers at the front stage, preamplifier for cassette recording/playing, and a 2-wire serial bus. - Features 1) Provides Surround and Bass Boost with the Soft-switching feature to reduce the shock sound at switching (BD3401KS2) 2) Provides a specialized power supply terminal in a digital circuit, in order to set and maintain the state inside the IC by the minute stand-by current. 3) Built-in preamplifier for cassette recording/playing allows for minimal external ponents, freeing up board space. 4) Arranges all I/O terminals to a single point and allows easy PCB routing. 5) Volume and Tone implemented with a resistance ladder circuit; achieving high performance with low noise and low distortion 6) Energy-saving design resulting in low current consumption, by utilizing the Bi CMOS process. It has the advantage in quality over the scaling down the power heat control of the internal regulators. - Applications BOOM BOX, mini-audio systems, and micro-audio systems. - Product lineup Parameter Equalizer Volume Cassette Recording/Playing Amplifier Karaoke Microphone Input Subwoofer Output Output for Spectrum Analyzer Surround Bass Boost Package -...
