RB991 utilizes two massive power supplies featuring a custom built toroidal transformer followed by individual rectifier arrays and capacitor banks for each channel.
Switchable balanced (XLR) and unbalanced (RCA) inputs provide flexible system interface.
Front panel heat sinks add a strikingly dramatic look and serve a functional purpose by enhancing heat dissipation even in cramped environments with restricted air flow.
