Model CM4-750

4 Channel High Power Dual Mode 70 Volt DSP Amplifier

AudioControl’s 70 volt amplifier solutions deliver superior quality power and sound through a large number of speakers, ideal for outdoor audio systems as well as a large variety of commercial A/V applications. DSP control and signal matrixing capabilities from AudioControl’s award-winning Director Series amplifiers enable integrators to precisely tailor the sound to any environment. Choose from balanced/unbalanced analog, microphone and digital inputs. Outputs can be configured in mono or stereo, giving integrators the configuration flexibility they need to accommodate any system architecture. For maximum efficiency, system setup and diagnostics can be managed remotely via an IP web-based browser or app for PC, Mac, iOS, and Android via IP.

Power and Control at your Fingertips

The CM Series feature on-board digital signal processing, graphic & parametric equalization by zone, network monitoring and programming, digital and analog 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 CM 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.
