When you need a space-saving solution for mixing multiple mic/line signals in conference rooms, houses of worship, or small-scale event venues, consider the 1 RU rack-mountable Rolls RM89 eight-channel mixer. It features six balanced 3-pin XLR microphone inputs with individually selectable 15 VDC phantom power to accommodate dynamic or low-power condenser microphones. A single tone control allows you to boost/cut the high/low frequencies across all six inputs. Plus, the mixer's two unbalanced stereo RCA source inputs offer easy connectivity for a wide range of consumer audio devices; these source inputs feature bass and treble controls. A front-panel 3.5mm jack parallels the Source 2 rear-panel input.
The summed output is fed through a master level control to a rear-panel mono XLR male connector and an unbalanced stereo RCA output. The mono XLR output can be set to mic or line level via toggle switch.
