Description
AudioControl Director M4840 8-Channel Network Matrix DSP Power Amplifier
High-Performance Matrix Amplification in a Compact Shallow-Mount Form
The AudioControl Director M4840 is a compact, shallow-mount 8-channel DSP matrix power amplifier that delivers 100 watts per channel into 8 ohms and 200 watts per channel into 4 ohms with all channels driven, in a 2U chassis just 11.75 inches deep. Designed for both home and commercial installations where rack depth is constrained, the M4840 combines high-performance multi-channel amplification with a comprehensive DSP processing suite including EQ, delay, crossover, volume control, and built-in speaker optimisation profiles, all controllable via network commands. With four stereo analogue inputs, four digital combo coaxial/Toslink inputs, and a built-in matrix capable of routing any analogue or digital input to any zone or digital bus output, the M4840 is a thoroughly capable and elegantly compact solution for performance-oriented multi-zone audio installations.
Comprehensive DSP Processing and Speaker Optimisation
The M4840’s onboard DSP processing delivers network-programmable graphic and parametric equalisation with user memories, programmable electronic crossover for local subwoofer applications, a subsonic filter, and built-in speaker optimisation profiles for compatible loudspeaker models. Assignable names for all zones and amplifiers simplify system commissioning and daily operation, while digital signal sense ensures sources are detected and managed automatically. AudioControl’s LightDrive anti-clipping speaker protection monitors the output continuously to protect connected loudspeakers from the distortion and damage associated with amplifier clipping during dynamic peaks. A damping factor greater than 300 and a signal-to-noise ratio greater than 95dB (A-weighted, referenced to full output) reflect the M4840’s commitment to amplifier quality alongside its processing capability.
Flexible Matrix Routing and Network Control
The M4840’s built-in matrix allows any analogue or digital input to be routed to any zone or digital bus output, with four stereo analogue loop outputs, two digital coaxial bus outputs, and four digital combo coaxial/Toslink loop outputs providing comprehensive signal distribution throughout the installation. Ethernet port connectivity via 10BaseT TCP/IP supports status monitoring, source switching, and 12V trigger control via HTTP or Telnet communication protocols, enabling seamless integration with any network-based control system. A 12V remote power trigger compatible with both contact closure and external 12V sources provides additional control flexibility for any installation configuration.
Shallow-Mount 2U Design for Space-Constrained Installations
At just 11.75 inches deep and weighing 7.5kg, the M4840 is specifically engineered for installations where rack depth is limited, including furniture-mounted equipment cabinets, in-wall rack enclosures, and any installation environment where a standard-depth amplifier chassis is impractical. Rack mount brackets are included in the box alongside speaker connectors, remote connector, power cord, manual, and warranty documentation, ensuring the M4840 arrives ready for immediate installation.
