The RME AVB Tool is a tool that takes four analog audio sources and converts them to digital signals that can be streamed over Ethernet AVB or MADI. It offers four XLR-1/4" inputs that can accommodate signals from Hi-Z instruments, microphones, and line-level sources. It also offers two 1/4" line outputs and a headphone output.
On the digital side, you'll find MADI offered over BNC or optical (over SFP) connections, as well as an Ethernet port for up to 128 channels of AVB. You'll also find clocking I/O over BNC connections.
The analog section offers a professional, pristine sound, with up to 75 dB of gain in 1 dB steps, as well as an input line-level sensitivity of +18 dBu. Each input can be switched to handle signal from DI guitars, line-level keyboards, or microphones.
On the AVB side, you can make use of eight streams in AM824 or AAF formats. The two MADI sections can run independently, or can be mirrored to facilitate redundancy. You can control the unit from the intuitive front panel, which offers a prominent encoder knob and multiple buttons. However, you can also control the unit over any network, wired or wireless, using RME's web-interface control. A power supply is included.
