BD34700FV
4ch Sound Processor with Built-in Micro-step Volume

The BD34700FV is a 4ch independent volume system. Micro-step volume can reduce the switching pop noise when volume changes, so it can achieve a high-quality set. It is most suitable for subvolume of the multi channel volume such as AV receivers, but is most suitable for main volume of simple systems such as 2ch.
