Making Connections

Bluetooth/Wi-Fi Antenna

Attach the two Bluetooth/Wi-Fi antennas that are included in the MX123 accessory package. Each antenna screws into a connector labeled

BLUETOOTH/WI-FI ANT located in the top right and left corners of the rear panel. After attaching the antennas, point them upward.

10baseT LAN

Use an Ethernet cable to connect the MX123 to a network router. The network connector is located on the top left rear of the MX123. It is labeled NETWORK. By default, the MX123 has DHCP set to ON and will automatically receive an IP address from the router. This setting can be changed. (See “Network” on page 24.)

8

HDMI

The MX123 has 7 HDMI Inputs. A highperformance HDMI cable is recommended to take advantage of the 18 Gbps speed capabilities of all 7 HDMI Inputs. The HDMI cables should support 4K@60Hz, HDR and YCbCr 4:2:2 (4:4:4/RGB) as well as Ethernet and ARC. Cables designed for

HDMI 2.0 are fine. Though, HDMI is backward compatible, older cables my have issues with the higher bandwidth.

Use HDMI OUT MONITOR 1 when connecting to an ARC (Audio Return Channel) enabled television. ARC can provide two-way communication between units allowing for volume control and lip-syncing functions to ensure audio and video are perfectly matched. This allows for more intelligent operation between components as well as less cable clutter. Make sure the ARC is enabled in your TV’s setup menu.

USB

There are two type-A ports on the rear of the MX123. The port labeled POWER SUPPLY is used to supply power (5 volts / 1.5 amps) via a USB cable. The second port, labeled USB, is for USB memory devices. Use this second port for accessing music from USB storage devices. Plug the USB memory device directly into the port. USB hubs will not work. Because of the vast array of USB memory devices available from countless manufacturers, McIntosh does not guarantee that all USB memory devices will operate or receive power.

Microphone

The microphone Input is for connecting the supplied MX123 Microphone using the microphone’s attached cable and an 1/8 inch connector. The microphone is used in the Audyssey® calibration for

tuning the system to your room. For instructions see “Audyssey®” on page 28.

RS232

The RS232 jack is used to connect the MX123 to automation controller devices with RS232

connectors. To utilize this feature, you will need an appropriate RS232 Data Cable. The RS232 Data Cable should be an 1/8 inch (3.5mm) stereo mini phone plug to a subminiature DB9 connector.

Typical RS232 settings are:

•8 data bits, no parity and one stop bit

•Baud rate fixed at 115,200 bits per second

Wired IR Inputs

The IR Input allows an external IR receiver to be attached to the MX123. The Input is labeled IR IN. By attaching an IR receiver using a 3.5mm cable

(See Figure 07), the MX123’s Remote Control can be used in another location without a line-of-sight to the MX123’s front IR sensor. In this way, if ZONE 2 is another room, a Remote Control can be used to adjust the MX123.

If using an external IR receiver for the MAIN ZONE in the same room as the MX123, you may wish to disable the front IR sensor, which also controls the MAIN ZONE. This will avoid potential timing issues of receiving the Remote Control’s commands from two different Inputs. The front IR can be turned on/off by doing the following:

•Put the MX123 in STANDBY mode

•While pressing and holding the front panel ENTER and RETURN buttons, press the STANDBY button (a 3-button push)

•Use the Down Arrow on the Front Panel or Remote Control to navigate to the RC LOCK Off option to enable the front panel IR sensor or choose RC LOCK On to disable the front panel IR sensor. See Figure 08

•Pushing ENTER will make the selection and reboot the MX123

Figure 08–  Setting the Remote Control Lock

Digital Inputs

There are four digital Inputs in the MX123:

•Two Toslink Optical Inputs

•Two Coaxial Digital audio Inputs The two Coaxial Inputs are labeled:

•1 (CBL/SAT)

•2 (DVD)

The two Optical Inputs are labeled:

•1 (TV AUDIO)

•2 (CD)

The default names and assignments can be changed in setup.

The Optical Inputs require a Digital Optical Audio Cable Toslink Cable. The Coaxial Inputs use Digital Audio Coaxial Cables with male RCA type connectors.

Analog Audio Inputs

There are eight pairs of gold-plated RCA jacks. The left jack of the stereo pair is on top, and the right jack is below it. They are labeled as follows:

1.PHONO

2.TUNER

3.CBL/SAT

4.DVD

5.BLU-RAY

6.GAME

7.CD

8.MP

To the left of the PHONO jacks is a ground connection labeled GND for connecting a turntable’s ground wire. The PHONO section of the MX123 is designed to work with Moving Magnet cartridges.

There is one pair of Balanced XLR Inputs. It is

labeled XLR BALANCED Input. Looking at the back of the unit, the Right Input is on the left and the Left Input is on the right.

There are eight gold plated RCA jacks designed for 7.1 Channel Input. They are located under the heading 7.1 CH Input. They are labeled:

•FL (Front Left)

•FR (Front Right)

•C (Center)

•SUB (Subwoofer)

•SL (Surround Left)

•SR (Surround Right)

•SBL (Surround Back left)

•SBR (Surround Back Right)

All the Input names can be customized in the SETUP program, as well as hidden and restored. Hiding Inputs spares you from scrolling through unused Inputs.

AC Power

This connection is essential. Plug the female end of the supplied AC Power Cord into the AC connector located in the rear right corner of the MX123. Plug the male end of the AC Power Cord into a grounded and functioning AC outlet.

Balanced Audio Outputs

There are 15 male balanced XLR connections on the back of the MX123 to accommodate a wide variety of speaker configurations. Connect balanced XLR cables to the corresponding powered speakers or amplifiers. Here are the possible connections:

•FL (Front Left)

•FR (Front Right)

•C (Center)

•SW1 (Subwoofer 1)

•SW2 (Subwoofer 2)

•SR (Surround Right)

•SL (Surround Left)

•SBR (Surround Back Right)

•SBL (Surround Back left)

•HR1 (Height Right 1)

•HL1 (Height Left 1)

•HR2 (Height Right 2)

•HL2 (Height Left 2)

•HR3 (Height Right 3)

•HL3 (Height Left 3)

This is all easier said than done. Setting up speakers for a surround setup takes planning, measuring and installation. Depending on your level of expertise and available time, you may wish to employ the services of your McIntosh dealer for expert setup of your system. Professional installation of in-ceiling speakers is particularly important due to gravity and the location above your head.

The number, types and locations of speakers are key elements in setting up the system. There is a multitude of possible configurations, and the

MX123 is very flexible in its setup to adapt to many of these configurations.

Often surround setups are referred to by numbers for example 7.1.4 or 9.1.2. The first number refers to the number of traditional surround speakers (front, center and surround). The second number is the number of subwoofers that can be connected, and the third number refers to the number of in-ceiling or upward firing speakers in the setup.

The type of speaker (size and location) will be entered later during Speaker setup. The distance of the speaker from the listening location will be entered in the Audyssey® setup. Make note of this information.

10

At this stage, the connection from the MX123 to the various amplifiers and powered speakers should be made using quality balanced XLR cables.

Power Control (Trigger) Outputs

The MX123 has two Power Control Outputs or Triggers. Power Control enables power on/off signals to go to connected components so that other components can automatically power on (or off) as called for by the MX123. For example, you may want a DVD player and a certain monitor to power on when HDMI 1 Input is selected, or you may want all components to power off when powering off the MX123. For Setup instructions see “General Setup” on page 24.

Connect components using a 3.5mm stereo mini plug. See Figure 09.

Analog Audio Output

Two additional Zones labeled ZONE2 and ZONE3 can be fed analog signals using a pair of RCA cables for each Zone. The jacks are located under ANALOG AUDIO OUT on the right side of the rear of the MX123.

Data Out

The MX123 will convert IR Remote Control data to share with McIntosh components connected to the Data Ports. This will allow units that are out of range of an IR signal to receive commands.

To connect a McIntosh unit to a Data Port, use a 3.5mm stereo mini phone plug cable. See Figure 10.
