The BD34701KS2 is designed for multi-channel home theater and surround audio applications. ROHM describes it as an 8-channel independent volume system that can be configured for 7.1-channel surround.
Its micro-step volume helps reduce "shock noise" that can occur when changing volume, improving perceived audio quality and user experience in premium AV equipment.
For system integration, the device also supports multi-source connection scenarios through input selection features suitable for multi-channel and zone-oriented audio designs.
8ch independent volume system supports surround designs.
Reduces switching shock noise during volume changes.
Input selection architecture supports complex AV routing.
Designed to help achieve premium multi-channel audio sets.
Supports 7.1ch surround configuration by design.
Helps suppress audible "click/shock" during volume transitions.
Designed for multi-source and multi-channel AV systems.
