D.O.TEC® MA2CHBOX.XT is a reference class headphone amplifier for MADI and AES signals with extended functionality. The device provides two standard MADI ports (AES10), an AES port (AES3) 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 AES 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.
The encoder knob on the front panel provides direct access to output volume, channel selection and the setup menu.
With its excellent sound quality and the straight forward operating concept, the D.O.TEC® MA2CHBOX.XT becomes a perfect toolbox for line checking, monitoring, signal conversion and redundant recording in MADI setups.
- two channel monitoring out of 258 channels (4 x MADI or the AES input signal)
- deembedding AES from MADI
- embedding AES into MADI
- signal conversion between optical and coaxial signals
- power supply safety class 1 (C13 connector)
D.O.TEC® 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).
Mobile Line Check
Battery powered the MA2CHBOX.XT may act as mobile monitoring solution. Input selection between MADI coaxial or MADI optical or AES.
The MADI signal from the mixing desk is fed to the MA2CHBOX.XT. The selected channel pair is output at the AES port feeding e.g. digital studio monitors. An EC port is connected to a laptop to record the MADI signal.
