BD34705KS2
ROHM Musical Device MUS-IC™ Series, 7.1ch Sound Processor with Built-in Micro-step Volume
The BD34705KS2 is an 8ch independent volume system. The system is designed to allow 7.1ch surround system application. It is improvement that sound quality more than the conventional products. Micro-step volume can reduce the switching pop noise during volume attenuation, so a high quality audio system could be achieved. 8ch triple input selectors for zone 3 and multi channel input enable the connection with a number of sources.
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".
