The Rolls RA163 Distribution Amplifier features 2 balanced inputs and 8 balanced outputs over XLR connectors. The RA163 will split a stereo input signal into 4 stereo outputs, or a mono input signal into 8 mono outputs. The unit can be used for high-end audio applications such as fixed-installations, sound reinforcement and more. Each output features individual level control dials and the chassis easily occupies a single space of a 19" rack enclosure.
