7.1ch Sound Processor for High-Quality Audio with Built-in Micro-step Volume - BD34704KS2
The BD34704KS2 is an 8ch independent volume system realized high-quality sound by improved specification of op-amp and optimized layout of the element.The system is designed to allow 7.1ch surround system application. Micro-step volume can reduce the switching pop noise during volume attenuation, so a high quality audio system could be achieved. This IC is available 12ch single-end input selectors to maximum 3 zones. And also available 2 system multi input selector.
It is the masterpiece of ROHM audio IC which pursues both the numerical values and sound quality performance required in an audio device to the utmost limits and created through the ardency of ROHM engineeers. That is ROHM Musical Device "MUS-IC".
