AudioControl Maestro M4

Audiophile Quality Preamp Outputs
The Maestro M4 is designed to be a high performance theater processor which also performs as an audiophile quality pre-amplifier. The best possible components were chosen, including high speed 24 bit, 192kHz digital to analog convertors (DAC’s), extremely transparent pre-amp circuitry and ultra robust drive circuits. To that extent the Maestro M4 is equipped with both unbalanced (RCA) and balanced (XLR) output connectors for optimum audio performance.

HDMI Inputs and Outputs
The Maestro M4 is equipped with over 120 individual audio and video inputs and outputs, HDMI (High-Definition Multimedia Interface) inputs and outputs. The new generation HDMI inputs will allow the Maestro M4 to interface with Blu-Ray players, satellite and cable decoding boxes plus traditional DVD players that also have HDMI connectors. HDMI is an uncompressed all digital interface standard used on many home theater products equipment. This format is used for sending audio, video, and control signals over short distances on a single cable. The dual HDMI outputs are assignable to allow for priority switching via the display device. Component, composite and S-Video signals can also be automatically upconverted, scaled to their maximum potential resolutions and output through the HDMI ports.

High Definition Surround Sound Formats
The Maestro M4 supports the latest surround codecs of Dolby True HD and DTS-HD Master along with traditional formats of Dolby Digital 5.0 and DTS High Resolution. A powerful 32 bit DSP processor enables the Maestro M4 to decode all current discrete surround digital formats available for 5.1, 6.1 and 7.1. In addition your Maestro M4 has the capabilities to process two channel signals using Dolby Pro Logic II, Pro Logic IIx and DTS Neo to provide multi-channel output.

Inputs For Networked Audio and USB Sources
The Maestro M4 is designed to operate with all of today’s traditional source units, like satellite or cable S.T.B., HDMI enabled media players and 3D Blu-ray players. Additionally it can receive audio signals over a computer network via an Ethernet input and or from a USB source. You will want to contact a professional audio integrator for more information on properly using these functions.

Extensive Automation Integration
An automation system is what really pulls most high-end home theaters together. It puts the full power of the system at your fingertips. While the Maestro M4 will operate with a number of IR remote controls (sold separately), it is equipped with a dedicated RS-232 serial port for control (labeled “Control”) and an extensive command library to control all aspects of the Maestro M4. Using this port requires a fair amount of programming and automation skills which are typically best done by professional custom installations companies.
