When you need a space-saving solution for mixing multiple mic/line signals in conference rooms, houses of worship, or small-scale concert venues, consider the 1 RU rack-mountable Rolls RM82 8-Channel Mic/Line Mixer eight-channel mixer. It features eight balanced 3-pin XLR microphone inputs with individually selectable 48 VDC phantom power to accommodate dynamic or condenser microphones. Plus, its eight unbalanced 1/4" TS inputs offer easy connectivity for line-level inputs or may be configured to function as inserts (for external processing) or direct outputs (for routing to a multitrack recorder). A mono RCA auxilliary input accepts an additional line input.

Adjustable trim, level knobs, and treble/bass cut circuits on each channel allow simple and efficient mixing control from the front panel. The summed mono output is fed through a master level control to a rear-panel XLR male connector. Plug the RCA output into an audio recorder to preserve a dedicated mix signal that is independent of the master level.

Key Features:

  • Eight balanced microphone inputs via 3-pin XLR female sockets
  • Eight unbalanced line inputs via 1/4" TS jacks
  • Each line input can be internally jumpered to function as a channel insert or direct output
  • Per-channel tone control cuts up to 12 dB of treble (above 6 kHz) or bass (below 200 Hz)
  • Adjustable trim and level on each channel
  • Line-level XLR main output can be switched internally to output mic-level signal
  • Ninth unbalanced input via mono RCA aux input jack
  • RCA pre-fader output is independent of the master level control
  • Connect the RCA pre-fader output to the RCA aux input of a second RM82 (available separately) to enable master level control of both devices from the first RM82
  • Dedicated power switch and LED power indicator
  • Rack-mountable enclosure occupies just 1 RU of rack space
