The Director® Model D4400 (DISCONTINUED)


Referring to AudioControl’s Director series as “just another set of amplifiers” is not entirely unlike calling a Ferrari “just another car.” With an incredibly powerful array of features—not to mention the capacity to deliver unrivaled audio performance across the whole music system— AudioControl’s network amplifiers redefine the very purpose of an amplifier.

The Director Model D4400 from AudioControl offers both system amplification and programmable signal processing via an Ethernet connection. This unique multi-channel product couples highly powerful, yet efficient, amplification with a powerful DSP (digital signal processor). This premium product also breaks new ground by providing custom installers with power and flexibility in a single, compact three U spaced chassis.

The heart of The Director D4400 amplifier platform is a newest generation amplifier topology and design. The benefits of this new amplifier platform are incredible efficiency and musical sound quality, while maintaining a high level of reliability. Power output is rated at a minimum of 100 watts per channel into 16 channels at 8 Ohms and 200 watts per channel at 4 ohms; all channels driven. The Director Model D4400 is also bridgeable and while the power output is rated at 8 ohms, it is stable into lower impedances, which allows for additional installation flexibility.

AudioControl engineers utilized years of design experience to incorporate powerful Digital Signal Processing into The Director Model D4400. It is network accessible via rear-panel mounted Ethernet connections. The lengthy DSP feature set includes:


  • NEW Ability to import and export settings for back-up and to create FastStart templates
  • NEW Grouping of selected audio functions – muting and zone selection
  • NEW DHCP as default setting – facilitate faster network settings, especially with multiple units
  • NEW Network Device Discovery (UPnP)
  • NEW Compatibility with Class A, B, & C networks
  • NEW Volume Control Across All Zones
