General Information
General Information
1.For additional connection information, refer to the owner’s manual(s) for any component(s) connected to the MX151 A/V Control Center.
2.The Main AC Power going to the MX151 and any other McIntosh Component(s) should not be applied until all the system components are connected together. Failure to do so could result in malfunctioning of some or all of the system’s normal operations. When the MX151 and other
McIntosh Components are in their Standby Power Off Mode, the Microprocessor’s Circuitry inside each component is active and communication is occurring between them.
3.Sound Intensity is measured in units called Decibels and “dB” is the abbreviation.
4.LFE (Low Frequency Effects) refers to the Dolby Digital or DTS sound channel dedicated to sound effects (such as explosions) and is usually reproduced by the Subwoofer.
5.When discarding the unit, comply with local rules
or regulations. Batteries should never be thrown away or incinerated but disposed of in accordance with the local regulations concerning battery disposal.
6. For additional information on the MX151 and other McIntosh Products please visit the McIntosh Web Site at www.mcintoshlabs.com.
7.Zone A accepts, unbalanced/balanced Analog Signals and Digital Audio Signals. Zone B only accepts Analog Signals. When connecting source devices with audio ouputs to the MX151, make sure to also connect the unbalanced/balanced outputs for each source connected to Zone A Digitally.
8.MX151 is a two Zone Product (Zone A and Zone B). This allows two different Audio/Video Sources to be available simultaneously for two separate rooms. Zone B may be used to provide an Audio/ Video Output Signal for recording purposes, instead of a A/V signal to a second room. For more information contact your McIntosh Dealer or McIntosh Technical Support.
9.The MX151 Input Source Name “DVD” is equivalent to “V-Aux” on some Classic McIntosh Keypads and Remote Controls.
10.Up to two McIntosh Sensors or Classic Keypads can be wired in parallel for both Zones A and B.
11.The Zone A and Zone B IR Inputs, with 1/8
inch mini phone jacks, are configured for nonMcIntosh IR sensors such as a Xantech Model HL85BK Kit. Use a Connection Block such as a Xantech Model ZC21 when two or more IR sensors need to be connected to the MX151. To avoid possible interaction, disable the MX151
Front Panel Sensor. Refer to Setup Mode on page 34.
12.Setup Mode operations should be performed in the order they appear in the first Setup Menu presented, as they are interactive.
13.In order to hear bass frequencies below 80Hz, your system must include either a Subwoofer or Large Front Loudspeakers.
14.The MX151 has built-in HDMI Digital Video Selection and Digital Video Processing Circuitry to convert any Composite Video, S-Video, and Component Video Signals to Digital Video with the same resolution.
15.When there is a connection between the ZA HDMI output and a TV/Monitor the Component
Video 2 Ouput, ZA Video Outputs and ZA S- Video Outputs will be muted.
16.HDMI Cable lengths between source components and the MX151 also between the MX151 and the TV/Monitor, should not exceed 25ft (8.3meters). If there is need to use HDMI Cables longer than 25ft (8.3m) a high quality in line HDMI Buffer/Converter would be required for reliable digital signal transmission via the HDMI Connections.
17.The MX151 is designed to pass through a 3D Digital Video Signal from a source component to a 3D TV/Monitor via the HDMI Connections. It is extremely important the HDMI cables used for connections meet or exceed the HDMI High Speed Cable Standards for proper 3D Video Playback.
18.The Remote Control Supplied with the MX151 A/V Control Center is capable of operating other components. For additional information go to www.mcintoshlabs.com.
19.When the MX151 and a PC Computer are connected to the same ethernet network, the Web Interface built into the MX151 becomes available. This allows Operational Control and Setup Mode Functions, for the MX151, to be available on the PC Computer for changes and adjustments. It requires the latest version of the Internet Browser (Internet Explorer, Firefox, etc.) to be installed on the PC. For additional information refer to “Network Setup” on page 32 and “Advanced Setup and Operation” on page 46 in this Owner’s Manual.

Installation
Installation
The MX151 can be placed upright on a table or shelf, standing on its four feet. It also can be custom installed in a piece of furniture or cabinet of your
choice. The four feet may be removed from the bottom of the MX151 when it is custom installed as outlined below. The four feet together with the mounting screws should be retained for possible future use if the MX151 is removed from the custom installation and used free standing. The required panel cutout, ventilation cutout and unit dimensions are shown.
Always provide adequate ventilation for your MX151. Cool operation ensures the longest possible operating life for any electronic instrument. Do not install the MX151 directly above a heat generating component such as a high powered amplifier. If all the components are installed in a single cabinet, a quiet running ventilation fan can be a definite asset in maintaining all the system components at the coolest possible operating temperature.
When the MX151 is placed free-standing on a flat surface, allow at least 2 inches (5.08cm) above the top and 2 inches (5.08cm) on each side, so airflow is not obstructed. Allow 19-1/2 inches (49.53cm) depth behind the front panel. Allow 1-7/16 inch (3.66cm) in front of the mounting panel for knob clearance.
A custom cabinet installation should provide the minimum spacing dimensions for cool operation. Allow at least 2 inches (5.08cm) above the top, 2 inches (5.08cm) below the bottom and 2 inches (5.08cm) on each side, so airflow is not obstructed. The Custom Cabinet should be open backed and at least 12 inches (30.48cm) away from any surface such as a wall. Be sure to cut out a ventilation hole in the mounting shelf according to the dimensions in the drawing. Allow 1-7/16 inch (3.66cm) in front of the mounting panel for knob clearance.
