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.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
