Product Description

The MR-PRO is an extremely powerful analog audio generator to satisfy every need for the professional engineer. Proprietary user wave forms may be loaded via USB into the internal flash memory.p>

The rotary settings wheel combined with surrounding fast access function keys enables instant and intuitive operation without compromising fine adjustment capabilities. Instrument operation is further enhanced with a backlit LCD, illuminated mute button, safety hand strap, jack for external DC power supply and an USB interface for firmware updates.The MR-PRO is an extremely powerful analog audio generator to satisfy every need for the professional engineer. Proprietary user wave forms may be loaded via USB into the internal flash memory.



Innovative and unique technology includes continuous monitoring of the impedance of the connected load, the signal balance and the phantom power. Plus the integrated cable testing promotes MR-PRO to the level of a cable analyzer, simplifying trouble shooting tasks.
