AudioControl Maestro M4 Digital Surround Preamp / Processor [Expired]


no longer for sale

Selling my Audio Control Maestro M4 Processor. I really like this processor but I will be upgrading to the newer Audio Control M5 for Atmos support. 

I have been using this mostly as a 2.1 system in the last couple months but it has mostly been in storage since I bought it from the original owner. It has worked fine with my PC, Oppo BD-P105, and my Tivo Roamio system with HDMI through settings and locked to 1080P. Audio through the M4 has been so much better than the last few processors I've had.  
  
This processor shares much of its audio and video DNA with the Arcam FMJ AV 888. Audio Control is typically available through the custom install market. I believe the difference between this processor and a lot of the competition is that the 2 channel direct listening experience is far superior, as great attention has been paid to making it a complete audiophile preamplifier with the ability of producing top notch home theater.       

There are a few marks on the edges of the face-plate and one on the top rear of the cover but barely noticeable. Still very respectable looking. The front is some type of glass and does have micro scratches from dusting it, they only show up if you look at it with light reflecting off of it.     

This does not come with the remote or any accessories. IR codes for Audio Control or Arcam work just fine for any after-market remote.  I do have the original mint condition bound owner's manual. These originally retailed at around $5,900.00 All specs below.

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 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.
