New open box unit with all accessories and manuals!!!

The very best in music and film presentation - that's what you get with the MX151. Featuring the latest in HDMI technology with full support of 3D video pass-through, you'll see everything current Blu-ray discs™ have to offer. And when you combine the built-in Dolby® TrueHD and DTS-HD Master Audio™ decoding with the RoomPerfect™ room correction technology, which adjusts the audio signal to the specific acoustics of your space, the result is an enveloping audio experience that puts you in the center of the action. Do not install the MX151 directly above a heat generating component such as a high powered amplifier.

Dual Zone feature allows you to play different media simultaneously in two separate rooms with independent program selection and control. The vast array of digital and analog inputs can be custom labeled for simplified system operation and matched in volume level for a smooth transition between sources. Assignable balanced input and outputs, an analog phono section, bass and treble controls and optional processing up to 7.1 multi-channel using Dolby Pro Logic® IIx or DTS Neo:6 all enhance the two channel audio experience of the MX151. The Zone A connection instructions below, together with the MX151 Input Connection Diagram located on the separate folded sheets “Mc2A”, is an example of a typical home theater systems.

The MX151's unprecedented flexibility allows custom system design and function for every environment. Control options include traditional IR-remote, web based GUI, and interfacing with all third party control systems. Audio options for up to 12 channels, multiple subwoofers, or bi-amping of speaker systems are built in.
