1. For additional connection information, refer to the
owner’s manual(s) for any component(s) connect-
ed 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 Deci-
bels 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 repro-
duced 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 regula-
tions 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.
General Information
8. MX151 is a two Zone Product (Zone A and Zone
B). This allows two different Audio/Video Sourc-
es 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 equiva-
lent to “V-Aux” on some Classic McIntosh Key-
pads 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 non-
McIntosh 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
General Information
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/Con-
verter 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 con-
nected 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 “Net-
work Setup” on page 32 and “Advanced Setup and
Operation” on page 46 in this Owner’s Manual.
