JR SOUND / ADB-212 III

The ADB-212Ⅲ is a stereo audio signal distributor that achieves excellent signal transmission characteristics and low noise through the use of an electronically balanced circuit utilizing the latest circuit technology, enabling high-quality signal distribution.

This new audio line signal distributor features a mute switch on each output and an expanded output variable range of ±10dB. It's a high-performance, high-quality audio line signal distributor with 2 balanced inputs and 8 balanced outputs, providing a stereo 4-way split. It can also be used as a 1-input 8-way splitter thanks to its function, and two units provide a stereo 8-way splitter. Furthermore, it offers ±10dB level control, allowing for precise level matching of each device.
