Modular Digital Matrix Mixer, Up to 8 Mic/Line Inputs, Digital Signal Processor

The M-9000M2 Pre-Amplifier is designed to be used in conjunction with optional modules and can be configured for up to 8 inputs and 8 outputs. 9000 series modules as well as existing 900 series input modules can be used. The most appropriate modules can be selected depending on applications. It is equipped with signal processing and control functions necessary for sound reinforcement, permitting all parameters to be set at the mixer. Settings data can be stored inside the unit and called up using the keys on the front panel.

 

Available Configurations Include:

M-900MK2 Rack-Mount Mixer, 8 Module Ports, Black (2U)

M-9000M2 features include:

  • Modular Digital Matrix Mixer/Amplifiers for a multitude of applications including audio-visual, zone paging, room combining and many more
  • Easy to Configure and Operate
  • Exceptional Audio Quality
  • 24-bit, 48 kHz sampling
  • Ultra-Low Distortion - 0.0008%
  • Minimum Latency - 1.1ms (D-001T input to output)
  • Modular Mixer - up to 8 mic/line inputs and 8 outputs
  • Dual Channel Digital Signal Processor (DSP):
  • 10-Band Parametric EQ
  • High and Low Pass Filters
  • Compressor
  • Loudness Contour
  • Bass and Treble
  • Delay (MIXER mode)
  • 34 TOA Speaker EQ Presets
  • Single or Dual Channel Power Amplifiers 70.7 V, 25 V and low impedance models
  • Flexible Output Power - dual channel models allow 50% of either amplifier channel to be allocated to the other channel (Ex. A-9060DHM2: CH1:90W, CH2:30W)
  • Telephone Zone Paging - access up to eight zones with optional ZP-001T module
  • Flexible, integrated, operating system (Mixer + Paging Matrix)
  • Mixer functions along with simultaneous Priority Paging Matrix activation, each with 32 presets
  • Scene memory (x32) contains all mixer (non-priority) settings
  • Paging memory (x32) contains global (static) input settings, independent Xpoint assignments, paging trigger & paging output levels for all high priority (1, 2 & 3) inputs.
  • Both scene & paging memories are stored in a single template along with remote assignments, security lock and other global functions
  • Mixer & Paging functions are independent and mixer (scene) settings will not affect Paging (event) functions.
  • Rack-mount Kit Included
  • Five Year Warranty
