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 airf low 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.

The RoomPerfect Measure and Adjustment Process uses multiple measurement locations in the listening room to achieve the best possible acoustical results. The Focus Position (location in the room) is typically where one would be during serious viewing and listening. The Room Positions are other locations in the room where non critical viewing and listening occurs.

Notes: 1. Assemble the supplied Microphone Holder/

Stand/Boom Adapter and connect the Microphone to the MX151 MICROPHONE Connector on the Rear Panel using the supplied cable.

2. Set the trim controls on the MX151 to the flat setting position and the volume control to the normal listening volume level.

3. It might be advisable to temporarily switch off the room/house heating/cooling system while the Room Perfect measurement process is occurring. If there are open windows, they should be closed. All of these steps will allow lower testing volume levels and more accurate measurements.

Enhanced Remote Control Operation

The McIntosh MX151 has been factory configured for operating in a standard McIntosh Home Theater System. This consists of McIntosh Source Components connected via data ports to the MX151. Using the McIntosh Remote Control supplied with the MX151 it becomes possible to operate the basic functions of the McIntosh Source Components with one remote control.

In those Home Theater Systems where a nonMcIntosh Remote Control will be used controlling other types of equipment (such as a drop down projector screen, room lighting, etc.), the MX151 has an optional remote control operating mode known as Enhanced Mode. This optional mode may also be used when it is desirable to use the remote controls supplied with each of the McIntosh Source Components for complete operational functionality.

Note: If the Enhanced Mode of Remote Control oper-

ation is to be used, it is advisable to disconnect any Data Control Cables between the MX151 and McIntosh Source Components to prevent any unintended operation of those components.

To switch the Enhanced Remote Mode On, enter the MX151 Setup Mode, select the System Setup Menu, followed by the General Setup Menu and then “Enhanced RC ctrl” menu item. Refer to page 34 in this Owner’s Manual and page 7 of the MX151 Setup separate sheet.

With the Enhanced Remote Control feature active press the MENU Push-button on the Remote Control and the User Menu will appear On-Screen. Refer to figures 80 and 81. Also refer to the MX151 “User Menu-1” separate folded sheet contained in the Owner’s Manual Packet.

Introduction

The MX151 offers additional Zone A Left Front Channel and Right Front Channel Outputs, two balanced outputs and two unbalanced outputs. These Auxiliary Outputs (1 thru 4) may be used for additional subwoofer outputs or for using the MX151 built-in electronic crossover circuitry. In this guide, the example will illustrate connections along with Setup Mode Settings for using the MX151 Electronic Crossover Circuitry.

Almost all Loudspeakers incorporate acoustic

drivers and a passive crossover network. The passive crossover network channels the various audio frequencies to the appropriate acoustic driver taking into account the amplitude and phases of the audio signals the Loudspeaker reproduces. When an electronic crossover circuitry in the MX151 is used together with multiple Power Amplifiers and Loudspeakers, it is very important to maintain the correct amplitude and phases of the audio signals for accurate sound reproduction.

McIntosh’s Acoustics Laboratory has measured

McIntosh Loudspeakers (with separate Low Frequency/High Frequency connections) when used with the MX151 and has arrived at the optimum settings. There are two different settings. The first setting is for use with McIntosh Loudspeakers with a Low Frequency (Woofer) to High Frequency (Midrange/Tweeter) crossover frequency of 250Hz. The second setting is when the McIntosh Loudspeaker has a crossover of 80Hz. It is suggested to use these settings.

When the MX151 is used with non-McIntosh

Loudspeakers it is highly recommended to contact your Dealer for assistance. Your Dealer has the necessary measurement equipment and knowledge to properly set up the electronic crossover in the MX151 for your Loudspeakers.

Connecting the MX151 when using the Electronic Crossover

The following connection instructions and illustration on the next page are a supplement to the MX151 Zone A Output Connection instructions on page 11 of the Owner’s Manual and the separate folded sheet “Mc2B” Diagram. It is an example of a typical Home Theater System. Your system may vary from this, however the actual components would be connected in a similar manner. For additional information refer to “Connector and Cable Information” on page 5 of the MX151 Owner’s Manual.

Power Control Connections:

1. Connect a Control Cable from the MX151 ZA PC (Power Control) OUT Jack to the Power Control In on Zone A Power Amplifier One.

2. Connect a Control Cable from Zone A Power Amplifier One Power Control Out to Zone A Power Amplifier Two Power Control In Jack.

Perform additional Power Control Connections starting with step 3 on page 11 of the MX151 Owner’s Manual.

Analog Audio Connections:

3. Connect Balanced Audio Cables from the MX151

Zone A - L (Front Left Channel) and R (Front Right Channel) to Zone A Power Amplifier One (High Frequencies) Inputs 1 and 3 respectively.

Note: Unbalanced Audio Connections may be used

in place of the Balanced Connections.

4. Connect Balanced Audio Cables from the MX151

Zone A - AUX 1 (Left Front Channel) and AUX 2 (Right Front Channel) to Zone A Power Amplifier Two (Low Frequencies) Inputs Left and Right

respectively. Perform additional Analog Audio Connections for the remaining channels, HDMI Connections and AC Power Cords by refering to steps (6 thru 11) on page 11 of the MX151 Owner’s Manual.

Output Settings

Operation and Installer Menu:

In order to use the AUXiliary Audio Output in the MX151, for either additional Subwoofer Outputs or the Electronic Crossover Circuitry, the settings in the “Installer Speaker Configuration Menu” need to be changed from their default setting.

The following steps are based on having operated the MX151 A/V Control Center, including the Setup Mode. Refer to the MX151 Owner’s Manual - pages 17 thru 45 and the MX151 Installer and User Menu separate fold out sheets (supplied in the MX151 Owner’s Manual Package) for additional information.

In the following example, the Crossover Setting will be set up for a Bi-Amplified System using McIntosh Loudspeakers with an internal 250Hz crossover point between the Low Frequency Section and the Midrange/High Frequency Section. If your Loudspeakers are not McIntosh, contact your Dealer for assistance. The MX151 Electronic Crossover Circuitry will be activated with a crossover setting of 250Hz using the LinkwitzRiley 4th order filter.

Notes: 1. It is advisable to employ a Real Time Spectrum

Analyzer, with at least one third octave resolution, to verify correct levels and overall performance. RoomPerfectTM Circuitry in the MX151 is designed to correct for Room Acoustics and Room/Loudspeaker interactions. It is not intended to correct for Power Amplifiers with different amplifying gains or Loudspeakers with inherent irregular frequency responses.

2. When using the MX151 AUX Outputs to drive multiple Subwoofers instead of using the MX151 Electronic Crossover Feature for BiAmplifing a Full Range Loudspeaker, select one of the “Sub _ _ _” crossover point setting” instead of the “Custom” setting” for “AUX perform”. Refer to step 6.

1. Switch power On to the MX151 and TV/Monitor.

2. Press the SETUP Push-Button.

3. Select the “Speaker and Room Setup” from the Installer Menu. Then select “Speaker Configuration” from the Speaker and Room Setup Menu. Refer to figures 1 and 2.

4. To makes changes use the p (up) or q (down) Push-buttons to highlight the “EDIT/SELECT” menu item, then press the SELECT Push-button.

5. Change the “Speaker Configuration” Front Left and Right settings to either “XL” or XXL” if that is not the current setting. Refer to figures 3 and

4. Also refer to page 22 of the MX151 Owner’s Manual for additional information on the “XL” and XXL” settings.

6. Refering to figures 3, 5 and 6, select “AUX1/2 (L/R)” listed in the Speaker Configuration menu and change the settings as follows:

AUX perform - Custom AUX cutoff - 250Hz AUX order - 4th LiRi

Note: The “Gain Offset” Adjustments for the LEFT

and RIGHT Front Loudspeakers and AUX Outputs may be used to compensate for the differences in Power Amplifier gains.

7. Select “Save Change”, followed by Confirm Selection by selecting “Yes”. Refer to MX151 separate sheet “Setup 2”.

8. Then select “Verify Current Setup” and step thru all the settings using the SELECT Push-button. Refer to figures 7 and 8.

Using the previously mentioned acoustic analyzing equipment, measure and adjust if necessary the gains of the two Power Amplifiers (unless they have the same amplification gain) for the same relative levels across the broad range of frequencies in the Low and High Pass regions. Then perform RoomPerfect Room Correction procedures starting on page 24 of the MX151 Owner’s Manual.

Notes: 1. The analyzing circuitry in the MX151 is

designed to prevent voids in the frequency response curve. This could occur if the Low Frequency Output AUX1/2 (L/R) had a cutoff setting of 125Hz and the the High Frequency Output (Front L/R) had a cutoff setting of

Page 57

Auxiliary Output and Elecrtonic Crossover, con’t

500Hz. In such a case the MX151 would set the crossover point for both the Low and High Frequency Outputs to 125Hz.

2. When using both AUX1/2 (Balanced Outputs) and AUX3/4 (Unbalanced Outputs) at the same time, it is important to make sure the settings (AUX perform, AUX cutoff and AUX order) are set the same. This assures matching of the crossover curves Low Pass and High Pass, as there is only one set of Front Left and Front Right Channel Outputs. Refer to figure 6.

3. When the Electronic Crossover or Multiple Sub-woofer Mode of operation is active, the signal normally present at the Subwoofer Output is now available at the AUX Outputs only.
