1RU 8-channel Mixer

OUR PART #  PROSPEC-1U8M


This unit is a 1RU mixer, designed to operate in mono, stereo, or LCR applications, and offering 8 channels of professional quality Burr-Brown microphone preamps.

Features:

  • Balanced Left, Right, and Mono (center) XLR outputs use THAT Corporation Outsmarts devices.
  • All front panel switches are internally illuminated.
  • Individual Solo switch on each mono and stereo input channel.
  • Monitor headphone level control with 1/4” and 1/8” headphone connectors and rear panel APB mixer link connector.
  • Each input channel is assignable to Left-Right or Mono (Center) mix bus
  • Level and Pan controls on Mono input channels / Level and Balance controls on Stereo input channels.
  • Mono input channels have 48-Volt Phantom Power, High Pass Filter, Polarity Reverse and Assignment switches.
  • Stereo input channels have Mute, Polarity Reverse, and Assignment switches.
  • Individual Left, Right, and Mono (Center) Metering.
  • Front panel Left-Right sum switch
  • Mono input channel use Neutrik XLR/1/4” combo connectors and TRS insert points
  • Stereo input use individual 1/4” balanced left and right input connectors.
  • Low phase-shift, wide bandwidth electronic design derived from APB’s Spectra and ProDesk products.
