General Information

Ground

The C12000 System consists of two separate chassis; a “Controller” and a “Preamplifier”. When specific clarification is necessary for instruction, the separate chassis will be referenced individually with their corresponding names. Otherwise, “C12000” will be used to reference the unit as a whole.

2. For additional connection information, refer to the

owner’s manual(s) for any component(s) connected to

the C12000 Audio Preamplifier.

3. The Main AC Power going to the C12000 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 C12000 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.

4. Balanced and Unbalanced Inputs and Outputs can be mixed. For example, you may connect signal sources to Unbalanced Inputs and send signals from the Balanced Outputs. You can also use Balanced and Unbalanced Outputs simultaneously, connected to different Power Amplifiers.

5. Sound Intensity is measured in units called Decibels

and “dB” is the abbreviation.

6. The McIntosh C12000 is factory configured for

immediate use. It can also be customized to complement the components making up your system. Refer to the C12000 “Setup Mode” starting on Page 20 for additional information.

7. The Remote Control Supplied with the C12000 is capable of operating other components. For additional information go to www.mcintoshlabs.com.

8. The IR Input, with a 3.5mm mini phone jack, is 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 C12000. The signal from a connected External IR Sensor will have priority over the signal from the Front Panel IR Sensor.

9. Controller to Preamplier Cable Part No. 171872 is

three foot, shielded 23 conductor, male-to-female custom cable. Two cables are required between Controller and Preamplier.

Do not use any other cable when connecting the

C12000 Controller to the C12000 Preamplier.

Introduction

The McIntosh C12000 Preamplifier is one of the finest ever created. The Outputs have the ability to drive multiple Power Amplifiers with the versatility of choosing between any combination of Solid State and Tube amplification. The C12000 Audio Reproduction is sonically transparent and absolutely accurate. The McIntosh Sound is “The Sound of the Music Itself.”

Performance Features

Dual Chassis with Dual Mono Design - The Dual

Chassis design completely separates all power supply, microprocessor and control circuits from the pure audio circuits for total noise isolation. To further aid in channel isolation, the circuitry for both channels is totally separate, physically isolated and shielded; and incorporates two identical power supplies one for each channel, to help assure total channel isolation.

Vacuum Tube Phono Amplification - The C12000 utilizes Vacuum Tube Amplification Circuitry for the Phono Inputs. The circuits use the latest designs providing the lowest possible noise and distortion.

Selectable High-Level Amplification - The C12000 has the Output 1 and Output 2 ports dedicated to Solid State Amplification and Tube Amplification respectively. Combined with the ability to assign the Main Output to either use Solid State or Tube via the Trim

Menu (refer to Page 29), the C12000 is equipped to

deliver high perfromance in any environment for any preference.

Fully Balanced Circuitry - The C12000 utilizes the very latest in Fully Balanced Circuitry from the Input Connectors all the way to the Output Connectors for the lowest possible noise and distortion.

Phono Inputs - The C12000 has two precision Phono Preamplifier Circuits. They have the ability to be configured for Moving Coil or Moving Magnet Cartridges. The close tolerance resistors and

capacitors used in the RIAA Correction Equalization Circuitry provide an extremely flat frequency response.

Selectable Phono Cartridge Loading - Adjustable Capacitance and Resistance Loading are available for both Moving Coil and Moving Magnet Phono Cartridges. Resistance Loading is selectable from values of 25 ohms to 47,000 ohms. Capacitance Loading is selectable from values of 50 picofarads to 400 picofarads.

Adjustable Gain for Phono Inputs - The C12000’s Phono Inputs have a wide range of gain settings to

accommodate a variety of Phono Cartridges.

Illuminated Output Meters - The Illuminated Output Meters are peak responding, and indicate the output of the C12000 Phono Preamplifier.

Electromagnetic Input Switching with Level Trim Adjustment - Digital Logic integrated circuits drive

Electromagnetic Switches on all Inputs and operating functions for reliable, noiseless, distortion free switching. All the Inputs on the C12000 can be matched in level, so there are no abrupt changes in volume levels between the different Inputs.

Balanced Inputs - The Balanced Inputs allow the connection of a source component using long cable lengths without a loss in sound quality.

Precision Tracking Volume Control - Volume levels are controlled by a Precision Balanced Digitally Controlled Attenuator System with an Optical Encoder Rotary Control. This assures a 0.1dB tracking accuracy between channels. There are 214 individual

0.5dB volume level steps with no noise as the volume level is changed.

Variable Rate Volume and Balance Controls - The C12000’s Volume and Balance Control Circuitry provides an ideal rate of change with control rotation.

HXD® for Headphones - The C12000 Headphone Crossfeed Director Circuitry (HXD® ) improves the

sound localization for Headphone Listening. HXD

restores the directionality component of the spatial sound stage normally heard with Loudspeaker listening. HXD® is a registered trademark of McIntosh Laboratory, Inc.

Alphanumeric Fluorescent Display - The Front Panel Information Display indicates the Source Selection, Volume/Balance Levels and Setup Mode Selections. The display intensity is adjustable.

PASSTHRU Mode - The Automatic PASSTHRU Mode allows the C12000 to become part of a Home Theater Multichannel Sound System.

Remote Control with External Sensor Input - The Remote Control provides control of the C12000 operating functions and McIntosh Source Components connected to it. Enjoy your McIntosh System from another room in your home by connecting an external sensor.

Installation - C12000 Controller

The C12000 Controller 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 unit 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 C12000 Controller 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 C12000 Controller. Cool operation ensures the longest possible operating life for any electronic instrument. Do not install the Controller directly above a heat generating component such as a high powered amplifier. Also do not stack the C12000 Preamplifier on top of the C12000 Controller. 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 (15.2cm) above the top, 2 inches (5.1cm) below the bottom and 1 inch (2.5cm)

on each side of the Controller, so that airf low is not

obstructed. Allow 20 inches (50.8cm) depth behind the front panel. Allow 1-7/16 inch (3.7cm) 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.

Connecting Components

The C12000 has the ability to automatically switch power On/Off to Source Components via the Power Control connections. The Data Port Connections allow for the remote operation of basic functions using the included HR085 Remote Control. With an external sensor connected to the C12000, remote control operation of the system is possible from another room and/or when the C12000 is located in a cabinet with the doors closed.

The Connection Diagrams (Pages 16-19) are

examples of a typical audio 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 4.

Note: The C12000 Controller allows re-naming of

the Audio Input Names as indicated on the Front Panel Information Display. Example, “UNBAL 1” may be changed to “TUNER” or your own personal preference. Refer to Input Settings on Page 20.
