Audio Expander
The Audio Expander is a small peripheral that enhances the BMA 360DX by offering local connectivity to all types of audio devices in the room—including microphones, line inputs and outputs, and USB audio
There are 4 professional quality flexible analog channels that can be independently configured as either input or output.
Key Highlights
- As an input, the channel has a generously large gain range allowing it to connect to all types of professional and consumer level sources. For microphones that require it, clean +48 volt phantom power can be enabled.
- As an output, a channel can be configured for either line level or mic level.
- The USB-C connector provides driverless 2 channel USB Audio for Windows, Mac, and Linux computer systems, allowing easy BYOD connectivity.
- ClearOne P-Link provides audio, control, and power connectivity from the BMA 360DX using a single CAT 6 cable.
