Ex-Demo > DirectOut MA2CHBOX.XT

MA2CHBOX.XT is a reference class headphone amplifier for MADI and AES signals with extended functionality. The device provides two standard MADI ports, an AES3 port and two ExpressCard ports for use with RME MADIface. Any stereo pair or single mono channel out of four MADI streams or the AES input can be monitored at the headphone output and the AES3 output too. The AES input signal may also be embedded into the MADI stream. The MADI I/Os are designed both as coaxial BNC I/O and optical SC multi-mode transceiver.  With its excellent sound quality and the straight forward operating concept, the MA2CHBOX.XT becomes a perfect toolbox for line checking, monitoring, signal conversion and redundant recording in MADI setups. The ExpressCard I/Os (EC1 and EC2) are fully compatible to MADIface ExpressCards by RME. MA2CHBOX.XT can be ordered either as AC version with a C13 connector (safety class 1) or as DC version with two redundant DC inputs (Hirose).

External Monitors
The MADI signal from the mixing desk is fed to the MA2CHBOX.XT. The selected channel pair is output at the AES3 port feeding e.g. digital studio monitors. An EC port is connected to a laptop to record the MADI signal.

Mobile Line Check
Battery powered the MA2CHBOX.XT may act as mobile monitoring solution. Input selection between MADI coaxial or MADI optical or AES3.
