Installation

WARNING: The MA9500 is heavy (approx. 101 lbs). Please get help when moving the unit, and make sure your furniture or cabinetry is sturdy enough to hold it.

The MA9500 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 MA9500 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 MA9500 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 MA9500. Cool operation ensures the longest possible operating life for any electronic instrument. Do not install the MA9500 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.

A custom cabinet installation should provide the following minimum spacing dimensions for cool operation.
Allow at least 6 inches (15.24cm) above the top, 2 inches (5.08cm) below the bottom and 2 inches (5.1cm) on each side of the Integrated Amplifier, so that airflow is not obstructed.

Allow 20 inches (50.8cm) depth behind the front panel. Allow 1-7/6 inch (3.66cm) in front of the mounting panel for knob clearance. Be sure to cut out a ventilation hole in the mounting shelf according to the dimensions in the drawing.

Notes:

If you remove the feet from your unit, be sure not to lose them, as they will need to be reattached if you need to send the unit back for service.
Use an appropriately-sized Phillips drill bit, or you may cause damage to the screw heads, making the feet impossible to remove.

Connecting Loudspeakers

WARNING: To avoid injury due to electrical shock or damage to your unit, do not attempt to attach loudspeakers while the MA9500 is plugged into a power outlet.

Preparing the Output Terminal Posts:
Notes:

When attaching loudspeakers, make sure the wires you used for positive (+) polarity is connected between the matching positive connectors on both the speakers and the unit. Do the same for the wires you used for negative (-) polarity. Do not make a connection between the separate channels (left and right).
Refer to your speakers’ documentation to determine the correct Output Terminal Post to connect them to based on their ohm impedance. If your speaker ohm impedance falls between the MA9500s labeled Output Terminal Posts, used the nearest lower connection. Example: If your speakers have a 6-ohm impedance, connect them to the 4-ohm Output Terminal Post.
If you’re using banana plugs, loosening the Output Terminal Posts is not necessary. Make sure the posts are tight before you attach the banana plugs.

To prepare the Output Terminal Posts for wires, unscrew them with your fingers counterclockwise until the opening on the post is exposed. When wires are set inside, tighten by turning the posts clockwise until they stop, making sure not to overtighten*. Finally, to secure the wires in place, use the included McIntosh Wrench and turn the posts one quarter turn (90°) clockwise.

WARNING: Overtightening can cause damage.

Connecting Loudspeakers 1

Preparing Your Speaker Wire:
Your speaker cord will have two sections, each with a set of wires in casing – one for each polarity (positive and negative). Using your choice of tool (such as pliers or clippers), take one cord section from one end and gently cut away and remove about ½ inch of the outer casing, making sure not to cut the internal wires. Once the casing is removed and the wires are exposed, use your fingers to twist the wires together until they are as narrow as possible, resembling a screw. Repeat this process for the remaining sections on both ends of the speaker cord.

Connecting Loudspeakers 2

Connecting Speakers (Bare Wire):
After loosening the Output Terminal Posts, you will see an opening. Place your narrowed wires you previously exposed through the opening and tighten the posts using the method described in “Preparing the Output Terminal Posts”.

Connecting Loudspeakers 3

Connecting Speakers (Banana Plug):
Make sure the Output Terminal Posts are tightened via the method described in “Preparing the Output Terminal Posts” (if necessary) and connect the banana plugs into the holes of the appropriate posts.

Connecting Loudspeakers 4

Connecting Speakers (Spade Lug):
While the Output Terminal Posts are unscrewed, slip the openings of the forks of the spade lugs around the inner part of the posts. and tighten the posts using the method described in “Preparing and Tightening the Output Terminal Posts”.

Rotate the Volume Knob or use the Volume Buttons on the Remote Control to adjust the Volume. The current Volume level is represented by a percentage on the Display. Note: The Volume control does not affect audio through the Fixed Outputs.

Adjusting Trim Functions:
See Page 13 for instructions on entering, navigating, and adjusting Settings in the Trim Function Menu. The Remote Control will also adjust these Settings.

Note: The Balance, Input Trim, and Equalizer Settings in this Menu will only be adjusted and affect the currently selected Input and their configurations will be independently saved.

The following is a list of descriptions of the various options in the Trim Functions Menu.

Adjusting Audio Balance:
You may want one loudspeaker to be louder than the other. While on the Balance Setting, use the Volume Knob to adjust the meter to whichever channel you wish to be louder. The more filled the meter is under a channel, the louder that channel will get, while the opposite channel will get quieter.

Enabling/Disabling the Equalizer:
Turning On the Equalizer will allow you to adjust the sound frequency for the selected Input using the Frequency Adjustment Knobs. Sound will adjust for each Input that has it activated. Note: The Equalizer does not affect audio through the Fixed Outputs..

Adjusting Input Trim Levels:
Devices connected to the various inputs may be sending audio at varying volumes to the MA9500. This could result in uneven playback Volume when changing sources. To correct this, you can raise or lower the Volume of an Input as it enters the MA9500 by adjusting its Trim level with this Setting.

Adjusting Phono Resistance (Turntables):
With the MC Phono source Input selected, the option to change the phono resistance becomes available in the Trim Functions Menu. Make sure to match this number to your turntable’s recommended phono resistance level.

Toggling Stereo/Mono:
Stereo allows the left and right channels to have separate independent audio signals. Mono sends the same signal through both channels. You can toggle between the two with this Setting.

Toggling the Meter Backlights:
You can turn On/Off the illumination of the power meters here.

Adjusting Display Brightness:
Use the Volume Knob to adjust the Brightness level of the Display.

Enabling/Disabling HXD:
This option will become available if headphones are plugged in. Enable this option to experience McIntosh’s patented Headphone Crossfeed Director (HXD) or disable it to have unaltered audio playback through the headphones.

Muting the Audio:
Use the mute button on the front panel or the Remote Control to mute the audio coming from the MA9500.

Getting the Most Out of Your MA9500

Using the Autoformer:
Your MA9500 comes equipped with independent connectors specifically allocated for loudspeakers of 2-, 4-, and 8-ohm impedance. Separating these connections allows McIntosh to use its patented Autoformer to provide the full 200 watts of power regardless of your speakers’ specifications.

Using the Eight-Band Equalizer:
As with all McIntosh products, your MA9500 produces the clearest, most accurate form possible of any audio that pumps through it. If the audio sent from the source is suboptimal, however, then the “clearest, most accurate form” might not be ideal for every situation. If you find yourself wanting to adjust the audio frequencies, enable the Equalizer (with the button on the front panel or in the Trim Functions Menu) to activate the functionality of the eight Frequency Adjustment Knobs. Turning the Knobs will adjust from the low frequencies (25Hz) up to the high frequencies (10,000Hz). Experiment with different rotations of the knobs to produce your desired sound. The Equalizer will affect the sound for any Input that has it on, and its On/Off status will be saved per Input.

Using Bi-Amplification on Loudspeakers:

WARNING: If the loudspeakers you are attempting to connect for bi- amplification have Jumper Plugs connecting the mid/high and low frequencies, they must be removed before making the connections to the amplifier(s). Failure to do so may result in damage to your equipment.

The MA9500’s onboard power amplifier may be used in conjunction with a separate external power amplifier to connect a loudspeaker for bi- amplification, allowing more flexible power control to the separate mid/high and low frequencies of the loudspeaker. You will do this by first removing the McIntosh Jumper Plugs from the Output 1 ports and the PWR AMP ports on the MA9500. In their place, bridge each of the left and right channels of the Output 1 and PWR AMP ports with a shielded RCA Y splitter. Connect the open ends of each of the Y splitters to your separate external power amplifier.

Using the HXD with Headphones:
Enable Headphone Crossfeed Director (HXD) to improve the sound localization for your headphones. HXD restores the directionality component of the spatial sound stage, giving you the quality and immersion of a loudspeaker paired with the privacy of headphones.

Listening Worry-Free (Auto Protection):
The internal McIntosh Power Guard monitors and adjusts sound waves at the speed of light, preventing harsh sounding distortion and clipping that could damage your speakers. The Power Guard LED lights on the front panel will be lit when it automatically activates. The MA9500 also includes an internal Sentry Monitor, which guages the amount of incoming electricity and will automatically protect your unit in the event of improper current flow, allowing you to listen while knowing your unit is safe.

Using the Onboard Power Amplifier:
To use the internal preamplifier and power amplifier simultaneously, connect the Output 1 ports and the PWR AMP ports using the included Jumper Plugs. This audio will be produced through Output 1.

Using External Power Amplifiers:
While your MA9500 comes fully equipped with a preamplifier and a power amplifier with the capability of playing the crystal-clear audio you’d expect from McIntosh amps through your loudspeakers, you have the option to attach separate power amplifiers if you so choose. You can do this while using the onboard power amplifier, or you can disable the onboard power amplifier and only use separate ones.

Using MA9500 with External Amp:
Connect your loudspeakers to the MA9500 and use the Output 2 ports to send a signal to an external amplifier, leaving the McIntosh Jumper Plugs that are bridging the Output 1 ports and the PWR AMP ports right where they are.

Using Only External Amps:
To disable the functionality of the onboard power amplifier, disconnect any loudspeakers from the MA9500 and remove the McIntosh Jumper Plugs bridging the Output 1 ports and the PWR AMP ports. This will turn your MA9500 into a dedicated preamplifier, allowing you to send signals from Output 1 and Output 2 to external power amplifiers.

Using Audio Passthru:
When using the MA9500 as part of a home theater system, you will likely want to enable audio Passthru to ensure proper flexibility with your audio signals. To do this, connect a cable from one of your A/V processor’s trigger ports to the MA9500’s Passthru Input port. Then, connect left and right audio signals from the A/V processor to a left and right Input port, respectively, on the MA9500. Finally, enable that Input for Passthru in the Setup Menu (see Page 14).

Viewing Coax/Optical Inputs Sample Rate:
When coaxial or optical inputs are selected and producing a signal, the Display will show the sample rate of the signal under the input name. If no signal is being received through the inputs, the Display will show a dotted line under the input name.

Using USB Playback:
You can play audio from your computer through the MA9500 while it’s connected via USB. You can see the sample rate of the playback on the second line of the Display while the USB Input is selected. The sample rate is affected by the audio source, the software used for playback, and the Settings set in the McIntosh HD Control Panel software.

Installing the Software:

Note: The software must be installed before connecting the MA9500 to a Windows computer via USB. If you are using an Apple computer, installing the software drivers are not necessary; however, if you’d like to install the McIntosh HD Control Panel software, you can follow the same steps.

To control and play audio through the MA9500 from a Windows computer, you will need to download and install the software drivers to your computer first. You can find all the software at the following webpage: https://www.mcintoshlabs.com/products/integrated-amplifiers/MA9500

The download package includes the software drivers as well as the McIntosh HD Control Panel software. Under the “Downloads” section near the bottom of the product page, click the down arrow to expand, locate the software download link appropriate for your system, and click it to start the download. Navigate to the download location on your computer, find the .zip file containing the software, and extract it to a new folder. In the new folder with the extracted contents, find the install file, open it, and follow the on-screen prompts to install the software. Once installed, reboot your computer, and the drivers and the McIntosh HD Control Software will be installed. You are now free to connect your computer to the MA9500 via the USB Audio port on the rear panel and control it using the installed software.

If you are experiencing trouble getting audio from the MA9500 via USB, check your Output Settings on your computer to make sure the MA9500 is recognized and ready for playback.

Frequently Asked Questions

Q: What are the Jumper Plugs for? Why use them?
A: The MA9500 is an all-in-one integrated amplifier, equipped with the capabilities of both a preampli-fier and a power amplifier. With the Jumper Plugs connecting the Output 1 and PWR AMP ports, your device will preamplify and amplify your sound through Output 1. To allow greater flexibility with a wide variety of sound systems, we enabled the ability to remove the Jumper Plugs to use the MA9500 as a dedicated preamplifier without the power amplifier functionality. See “Using External Power Amplifiers” on Page 16 for details.

Q: What is the difference between Fixed Output and a regular Output?
A: A regular Output is designed to be used for listening. Sound from regular Outputs will behave as anticipated — adjusting the Equalizer or Volume, for example, will affect it appropriately. A Fixed Output is designed for recording devices. No adjustments can be made to sound coming from the Fixed Outputs, allowing you to listen to and adjust sound coming from the regular Outputs while knowing sound coming from your Fixed Outputs (and into a recording device) remains unaltered, meaning your recording source will be consistent.

Q: When I press the Input Control Knob, it isn’t doing what I expect. What’s wrong?
A: The Input Control Knob is designed to be pressed or held to activate various functions. To prevent unintended or incorrect Knob presses, we have implemented several ways a press can be read by the unit:

Deliberate Press: This is a press that is longer than a “Tap,” but not long enough to be considered a “Hold.” Pushing in deliberately will open the Trim Functions Menu and act as a “back” function while inside of most menus.

Press and Hold: Push the Knob in delibrately and hold it down for a couple of seconds to initiate a “Hold.” This will open the Trim Functions Menu or navigate further down into Submenu when a “Hold Input” prompt is displayed. Be sure not to hold down for too long or you may initiate service features. If you do, do a Deliberate Press to back out.

Tap: An extremely brief press of the Knob is considered a “Tap.” To prevent accidental commands from being registered, a “Tap” serves no function for the MA9500 and will not do anything.
Try altering the way you are pressing the Knob to see if that helps. If you feel that Knob presses are not working as intended, try resetting the microprocessors using the method described in the Note section under “Using Your MA9500” on Page 15.

Q: What is the difference between a Balanced and Unbalanced signal?
A: Balanced signals are able to split and replicate an audio source’s signal, which allows it to travel a large distance without any noise or distortion. You will use these Inputs when you need to run a very long cord to another location. Unbalanced signals are used for short distances, so they do not require this functionality. Use Unbalanced Inputs to run short cords between devices that are close together and you won’t run into any noise or distortion issues.
