To connect speakers to your ANTHEM MRX 1140, follow these steps. Ensure the receiver is powered off before making any connections.

1. Prepare Speaker Wire: Carefully remove the insulation from the end of your speaker wire using a wire stripper. Tightly twist the loose strands of wire together. Ensure no loose strands can touch other cables or the receiver’s case.

2. Connect to the Receiver: On the back of the ANTHEM MRX 1140, locate the appropriate speaker terminals (e.g., FRONT L, CENTER, etc.). Loosen a binding post by twisting it counterclockwise. Insert the positive (+) wire into the red (+) terminal and the negative (-) wire into the black (-) terminal.

3. Tighten the Connection: Tighten the binding post by turning it clockwise. Do not over-tighten. Gently tug on the cable to ensure it is secure.

4. Connect to the Speaker: Connect the other end of the wire to the corresponding speaker, ensuring the positive (+) wire from the receiver goes to the positive (+) terminal on the speaker, and the negative (-) wire goes to the negative (-) terminal.

5. Banana Connectors (US models): If using banana connectors, first ensure the binding post on the receiver is fully tightened (closed). Then, insert the banana plug fully into the back of the binding post.

Do not connect more than one speaker to each amplifier output. Only use speakers rated for use with the ANTHEM MRX 1140.

A network connection is required for features like Anthem Room Correction, streaming, and IP control on your ANTHEM MRX 1140. You can connect via a wired or wireless connection.

Wired Connection:

Connect a standard CAT Ethernet cable from your network router to the ETHERNET port on the rear panel of the receiver.

Wireless Connection:

1. Attach the two included wireless network antennas to the designated connectors on the rear panel.

2. Follow the setup instructions for connecting to a wireless network, which can be found in the AirPlay or Chromecast setup sections of the manual.

Note: Wireless antennas are also required for a Bluetooth connection. If mounting the ANTHEM MRX 1140 in a metal rack, a wired connection is recommended for better signal stability.

The ANTHEM MRX 1140 allows for up to four unique speaker profiles, each with its own speaker selections, bass management, listening position, level calibration, and ARC equalization values. This is useful for different room conditions (e.g., screen up vs. down) or listening preferences (e.g., stereo music vs. home theater).

To configure a profile, navigate to the Speaker Setup menu. Here you can access and edit each of the four profiles.

• Profile Name: Rename each profile (up to 16 characters). Note that ARC will overwrite this name when you upload a file.

• Subwoofer / Center / Surround / Etcetera: For each speaker in your system, set it to “On”. If you do not have a particular speaker (e.g., back surrounds), set it to “Off”. This is crucial for correctly rerouting sound to the available speakers. Front speakers are always required and cannot be turned off.

While profiles can be set up manually via the front display, it is easier to configure them using Anthem’s ARC Genesis software.

The Bass Management menu on your ANTHEM MRX 1140 allows you to configure how low-frequency sounds are distributed between your speakers and subwoofer(s). The bass manager is a crossover that divides audio into two frequency bands, sending less bass to your main speakers and more to the subwoofer, preventing distortion.

Key settings in the Bass Management menu include:

• Subwoofer Phase: Adds electronic delay to the subwoofer signal to better integrate it with the main speakers.

• Phase Frequency: Sets the frequency at which the phase shift is applied (generally the same as the crossover).

• Subwoofer Polarity: Can be set to Normal or Inverted to help achieve balance. Inverting the polarity makes the subwoofer’s driver move in the opposite direction of your main speakers’ drivers.

• Crossover Frequency: Sets the point at which bass is redirected from a speaker to the subwoofer. The range is 40 to 200 Hz. Setting a channel’s crossover to “Off” is not recommended.

• Super Sub Fronts: When set to “Yes”, full-range stereo is fed to the front left/right channels, and bass is also sent to the subwoofer. This effectively doubles low-frequency information and is not recommended for accurate reproduction.

For best results, these settings are set automatically when you run Anthem Room Correction (ARC).

Setting the listener position on your ANTHEM MRX 1140 ensures proper sound imaging by coordinating the audio from all speakers to reach your ears at the same time. The receiver adds a slight delay to the channels with shorter distances.

1. Navigate to the Listener Position menu in the setup options.

2. Select the speaker profile you wish to configure.

3. For each speaker in your system, enter the distance from that speaker to your primary listening area.

4. You can set the measurement units to “feet” or “metres” in the Preferences menu.

The range is 0-30 ft (in 2-inch increments) or 0-9 m (in 5 cm increments). Note that Anthem Room Correction (ARC) does not set these distances, so they must be entered manually.

The Level Calibration menu on the ANTHEM MRX 1140 uses internal test noises to match the output level of each speaker at the listening position. While Anthem Room Correction (ARC) performs this automatically, you can do it manually.

1. Navigate to the Level Calibration menu and select a speaker profile.

2. In the calibration menu, set Test Noise to “On”.

3. Use the up/down buttons on the remote to move the test noise from speaker to speaker.

4. While seated in the listening position, adjust each channel’s level until they all sound equally loud. If using a Sound Pressure Level (SPL) meter (with C-weighting), adjust each speaker until the meter reads 75dB SPL.

5. The Calibration Level setting adjusts the master volume for the test noises.

Level adjustment is limited to +12dB. If a speaker requires more adjustment, consider moving the speaker or the listening position.

The ANTHEM MRX 1140 allows you to create up to 30 “virtual” inputs, giving you full control over how your sources are configured. To do this, go to the Input Setup menu.

• To add an input: Highlight “Insert Input” at the bottom of the list and press SELECT.

• To delete an input: Highlight “Delete Input”, press SELECT, then highlight the input you wish to remove and press SELECT again.

For each input, you can configure the following settings:

• Input Name: Rename the input (e.g., “Blu-ray”).

• Video Input: Assign an HDMI input (1-7) or None.

• Audio Input: Assign an audio source (HDMI, HDMI eARC, Coaxial, Optical, Analog, Streaming, Bluetooth).

• Speaker Profile: Choose which of your four speaker profiles this input will use.

• Anthem Room Correction: Turn ARC on or off for this input.

• Dolby Audio Post Processing: Select Music, Movie, Night, or Off.

• Mode Presets: Set default listening modes for Mono, Stereo, and Multi-Channel sources for this input, or select “Last Used” to remember your last choice.

• Lip Sync: Set a permanent audio delay for this input.

• Input Trim: Adjust the input volume level to match it with other sources.
