Sounds great, Less filling

The Director Model M4840 squeezes 8 channels into a unique shallow-mount chassis ideal for tight fit rack or media cabinet installations. Go ahead and take the M4840 for a spin (click or swipe) and you'll be surprised at just how compact this powerful matrix amplifier really is.

Power And Control At Your Fingertips

The Director® M Series feature on-board digital signal processing, graphic & parametric equalization by zone, network monitoring and programming, local and bus inputs, plus the addition of volume control, channel/zone grouping and zone audio presets. They also allow individual channel and zone selection via standard TCP/IP, delivering incredible power and AudioControl’s legendary audio performance.








Two digital inputs and outputs are both accessible in the matrixing so that any one of the input sources can be routed through the digital outputs. These digital outputs can be connected to other CM Series, The Director M or D Series or Architect digital inputs so that multiple amplifiers can receive any signal from any of the inputs.

Speaker Optimization Profiles

AudioControl has partnered with a growing number of prominent architectural loudspeaker manufacturers to implement speaker performance profiles directly accessible from The Director® M Series onboard DSP. Each speaker manufacturer has provided critical performance data to AudioControl, enabling tailored profiles to be created and stored in software form. Factoring in the individual room acoustics for each home, these speaker profiles achieve an important step in providing the custom integrator the tools to deliver a premium entertainment experience by calibrating systems for their clients.
