Important Information

1. The C1000 System consists of two or three separate chassis. The C1000 Controller Chassis will be referred to as the C1000C throughout this Owner’s Manual. In a similar manner, the C1000 Preamplifier (Solid State) Chassis will be referred to as the C1000P and the C1000 Tube Preamplifier Chassis will be referred to as the C1000T throughout this Owner’s Manual.

2. For additional information on Audio Connections, refer to the Owner’s Manual(s) for the component(s).

3. Connecting Cables and Connectors are available from the McIntosh Parts Department:

Data, Power Control and Trigger Cable Part No. 170-202

Six foot, shielded 2 conductor, with 1/8 inch stereo mini phone plug on each end.

Controller to Preamplifier Cable Part No. 171-611

Three foot, shielded 24 conductor, male-to-male custom cable, two required between Controller and Preamplifier.

4. The Main AC Power Cable going to the C1000C and any other McIntosh Component(s) should not be connected to an AC Power Outlet until all the system components are connected together. When the C1000C 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. Failure to do so could result in malfunctioning of some or all of the system’s normal operations.

5. Up to four sensors can be wired in parallel for Remote Control of the C1000 from other rooms.

6. 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.

7. A McIntosh Power Controller may be added to the C1000 to provide AC Power Switching to components that do not have Power Control Connections. See your McIntosh Dealer for additional information.

8. When the C1000P and C1000T Preamplifiers are both connected to the same C1000C Controller ( refer to pages 20 and 21):

A. The Record Link Inputs on both preamplifiers need

to be connected together, thus allowing sharing of their inputs for recording purposes.

B. The McIntosh MDA1000 D/A Converter may be

connected to either the C1000P or C1000T Preamplifier.

9. Sound Intensity is measured in units called Decibels and “dB” is the abbreviation.

10. If the C1000P and/or C1000T Preamplifiers 21 conductor custom interconnect cable(s) become temporarily disconnected from the C1000C when it is On or in Stand-by Mode, a cable error message will appear on the C1000C. Remove the AC Power Cord from the C1000C, connect the

disconnected 21 conductor custom interconnect cable(s) and then reconnected the AC Power Cord. The C1000 System will automatically reset itself to the previous configuration.

11. When a C1000P or C1000T Preamplifier is added to an already existing C1000 System, the C1000C will automatically recognize the need to re-configure the C1000 System, refer to page 41 for additional information.

Introduction

The C1000 Preamplifiers with a Controller are the finest audio preamplifiers McIntosh has ever created. No design compromises were allowed in the quest for a preamplifier, both Solid State and Tube with absolute accuracy, total sonic purity and virtual elimination of distortion and audible noise. For those who have been searching for the “Best in Preamplifiers”, your wait is over.

Performance Features

Introduction and 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. The C1000 incorporates two identical power supplies one for each channel, to help assure total channel isolation.

••

• Balanced and Unbalanced Inputs/Outputs

••

Four balanced high level inputs and three balanced main outputs are provided. Four high level unbalanced inputs, two unbalanced outputs as well as listen and record processor loops are included.

••

• Moving Coil and Moving Magnet Phono Inputs

••

The C1000 contains two different shielded precision Phono Preamplifier Circuits. One is designed for low output Moving Coil Phono Cartridges and has selectable resistance loading. The second Phono Preamplifier is for Moving Magnet Cartridges and has selectable capacitive loading. Both circuits use the latest designs to provide the lowest possible noise and distortion. The RIAA Correction Equalization Circuitry utilizies 0.5% tolerance resistors and 1% capacitors for an extremely flat frequency response.

••

• Precision Parts

••

All resistors are precision metal film type. Low dielectric absorption film capacitors are used in all critical circuit locations.

••

Passthru Mode

•

••

The Automatic Passthru Mode allows the C1000 to become part of a Multichannel Sound System for DVD-Audio, SACD and Home Theater Movies.

••

• Remote Controls

••

The two Remote Controls included with the C1000 allow remote operation of the Preamplifier along with controlling various other McIntosh Source Components and Processors.

••

• Optional External Sensor Input

••

There are provisions for connecting external sensors, which allow for enjoying your McIntosh System from other room(s) in your home via the remote control.

••

• Power Control Output

••

A Power Control connection for convenient turn-on of McIntosh Source Components, McIntosh Power Amplifiers and accessories is included.

••

• Input Level Trim Adjustment

••

All the C1000 Inputs can be matched in level, so there are no abrupt changes in volume levels between the different inputs.

••

• Precision Tracking Variable Rate Volume Control

••

Volume levels are controlled by a Multi-Stage Precision Digitally Controlled Attenuator System with an Optical Encoder Rotary Control. This helps to assure a tracking accuracy between channels of 0.1dB, while providing 214 individual 0.5dB steps of change in the volume level and all of this with no noise as the volume level is changed.

••

• Balance Control

••

The Balance Control Circuitry allows for precise and repeatable change in channel balance in 1dB steps.

••

• Alphanumeric Fluorescent Display

••

The Multifunction Front Panel Display indicates the Listen and Record Source Selection, with Volume indicated in dB or percentage and Balance Levels in dB. Setup Mode Selections and Adjustments are also displayed.

••

• Glass Front Panel with Fiber Optic Illumination

••

The famous McIntosh Illuminated Glass Front Panel, with 1/2 inch thick sections, has a three dimensional look helping to ensure the pristine beauty of the C1000 will be retained for many years.The Illumination of the Front Panel is accomplished by the combination of custom designed Fiber Optic Light Diffusers and Light Emitting Diodes (LEDs). This provides even Front Panel Illumination, together with the extra long life LEDs.

••

• Machined Top and Side Panels

••

The Top and Sides of the C1000 are machined from thick aluminum panels with a smooth black anodized finish. In the recessed area of the Top Panel is a screened glass panel with a block diagram of the C1000 Circuitry.

••

• Special Power Supply

••

Fully regulated Power Supplies, one for each channel, utilize special R-Core Power Transformers helping to ensure stable noise free operation even though the power line varies.

The C1000C, C1000P and C1000T can be placed upright on a table or shelf, standing on their four feet. The four feet, may be removed from the bottom of the C1000C, C1000P and C1000T when they are custom installed as outlined below. The four feet, together with the mounting screws should be retained for possible future use if the C1000C, C1000P and C1000T are removed from the custom installation and used free standing. They also can be custom installed in a piece of furniture or cabinet of your choice. The required panel cutout, ventilation cutout and unit dimensions are shown.

Always provide adequate ventilation for the C1000C, C1000P and C1000T. Cool operation ensures the longest possible operating life for any electronic instrument. Do not install the units 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 2 inches (5.08 cm) above the top of the C1000C, C1000P and C1000T, 2 inches (5.08cm) below the bottom and 1 inch (2.54 cm) on each side of the Controller/Preamplifier, so that airflow is not obstructed. Allow 24 inches (61.0cm) depth behind the front panel1 for Interconnect Cables. Allow 1 inch (2.54 cm) in front of the mounting panel for clearance. When the C1000C, C1000P and C1000T are to be installed in custom cabinets refer to illustrations to the right. Be sure to cut out a ventilation hole in the mounting shelf according to the dimensions in the drawing.

Interconnect Cables are supplied with the C1000P and C1000T Preamplifiers and connect to the C1000C Controller.

Volume Display returns to the Volume reading. To verify the balance setting without changing it, move the control one detent in either direction. The display will indicate the selected balance changes for approximately 3 seconds and then return to the volume display.

The “L” or “R” will illuminate to indicate which channel has been emphasized by the BALANCE control. It is perfectly natural for the BALANCE control to be off the center to achieve the correct listening volume from each loudspeaker in many listening rooms. Listening balance can also vary with different program sources, room acoustics and listening positions relative to the loudspeakers.

You can also listen (monitor) to the recorded signal off the recording media, a fraction of a second later. You can also listen to the signal at the record outputs by pressing the REC MONITOR push-button.

1. Select the desired program source to record with the Front Panel RECORD Control.

2. Adjust the record level using the recorders volume con-

trol.

3. To listen to the signal at the record outputs going to the recorder, press the REC (Record) MONITOR pushbutton.

4. To listen to the playback of the program source just recorded, rotate the LISTEN Control to the desired input.

Note: The C1000 RECORD OUTPUTS are not affected by

the VOLUME or BALANCE Controls. To listen to a different program source while recording, turn the LISTEN Control to the desired source. The recording process will not be affected and will continue.

Output Meters

The C1000’s Output Meters indicate the Output Voltage available at the MAIN and SPKR OUTPUT 1 & 2 Jacks to drive Power Amplifiers. Refer to figure 70. The Meters are calibrated in dB (decibels) and respond to all the peaks contained in the musical information. They indicate to an accuracy

Figure 70

of at least 95% of a single cycle from a 2000Hz tone burst.

The Meter Electronic Circuitry “Time Stretches” the Meter Drive Signal so the Meter Pointer pauses just long enough for the human eye to see it and is followed by a moderate decay rate.

On, the left and right stereo signals will be combined to a mono signal at all Outputs except the Record Outputs. Refer to figures 71 and 72.

How to use the Passthru Mode

When the C1000 is connected together with a McIntosh Multichannel A/V Control Center or Surround Decoder and has the PASSTHRU MODE activated it will automatically turn-on when ever the A/V Control Center or Surround Decoder is turned On. It will indicate on the Front Panel Alphanumeric Display “PASSTHRU”. Refer to figure 84.

Figure 84

In the Passthru Mode, the LISTEN and RECORD Processor and OUTPUTS 1&2 Push-buttons remain active. The remaining C1000C Front Panel Controls and Push-buttons are deactivated as long as the C1000 is in the Passthru Mode. The C1000 will also remember the settings of the LISTEN and RECORD Processor and OUTPUTS 1&2 Push-buttons for the Passthru Mode; it stores these settings separately, from the settings when only the C1000 is On.

Reset of Microprocessors

In the event that the controls of the C1000 stop functioning press and hold in the STANDBY/ON Push-button. Three to four seconds latter the Front Panel Alphanumeric Display will indicate “DETECT SYSTEM”, at this point release the STANDBY/ON Push-button. This will reset the C1000 microprocessors.

Technical Description

McIntosh Laboratory, the company who introduced the world’s first amplifier that could be called “High Fidelity”, has done it again. The McIntosh Engineering Staff has created a Preamplifier without compromise, using the most advanced McIntosh circuit design concepts.

The C1000 is the third generation of a two chassis design with fully balanced circuitry that started with the introduction of the C100 in 1997. In the two chassis design, the power supplies and digital control circuitry are contained in the Controller Chassis and the second chassis contains the Preamplifier Circuitry. This prevents the possible introduction of hum and noise into the audio signal. In the C1000, an additional refinement has been added to help assure total channel isolation, dual mono design. There are two independent power supplies, one for each channel, and the Preamplifier also contains two totally independent preamplifier circuits. Refer to figures 93, 95 and 96.

Creating an Preamplifier with this level of performance did not come easily. Many months of design, testing and measuring were required. Extensive controlled listening tests, the ultimate form of measuring, were made before the final design was accepted.

Figure 93 - Top Inside View of the C1000C

Silent Audio Switching

All of the Audio Signal Switching in the C1000 is performed by 50 Electro-Magnetic devices. This includes the selection of the desired Audio Input Source for Listening, for Recording Outputs, External Signal Processing Loop, Final Audio Output Selection and the Audio Muting Function. These Electro-Magnetic devices switch silently, without adding noise to the Audio Signal for the lifetime of the C1000 Preamplifier. The Balanced Input Switching Printed Circuit Boards for one channel of the C1000 are shown in figure 92.

Figure 92

Electro-Magnetic Switching is a proven technology that uses the latest in materials and manufacturing methods.

Each switch consists of a glass tube filled with an inert oxygen-free atmosphere and sealed with tiny leads protruding from either end. These leads extend into the tube and overlap one another with a separation of a few thousandths of an inch. The leads are made from a ferrous material that is influenced by a magnetic field.

Figure 94

They are first plated with gold as a base material, then with rhodium and finally ruthenium. Ruthenium is the best contact material known. Refer to figure 94.

The glass assembly is then placed in the center of a multilayer coil of copper wire. The entire assembly is molded together in a tough shock absorbing material. The switch and coil connectors extend from the bottom in the form of printed circuit board terminals. When a DC voltage is applied to the coil, current flows and creates a magnetic field. The force of the field causes the leads to bend and contact one another inside the sealed glass tube. The inert gas eliminates corrosion of the contacts and insures a low resistance, distortion free switch.

Volume Adjustments

The most frequently operated control on a Preamplifier is the Volume Control. The desired volume level can vary by the type of music, size of our listening room and even the time of day with which we listen. So it is no surprise that McIntosh has devoted a substantial amount of time in pursuit of the “Perfect Volume Control System”.

A conventional Mechanical Potentiometer for a volume control is totally unacceptable for use in the C1000 Preamplifier. Mechanical Controls have poor tracking especially when it comes to maintaining channel balance and after a period of time they tend to introduce noise into the audio signal, as they are rotated. The one desirable thing they have is the rate of change in volume for degrees of rotation, known as the audio taper. Using Electronic Circuitry for controlling the volume can be designed to be free from noise and maintain channel balance, however the audio taper produced by the typical Electronical Volume Control Circuit is unacceptable for use in the C1000, as it does not match the classic McIntosh Volume Control Audio Taper. The C1000 incorporates electronic circuitry together with sophisticated firmware to produce electronically the classic McIntosh Volume Control Audio Taper, while maintaining the channel balance and freedom from control noise.

The Volume Control on the Front Panel of the C1000 is actually a special digital optical encoder. As the Volume Control is rotated, a beam of Infra Red Light is picked up

Figure 96 - Top Inside View of the C1000T

by two internal sensors as a series of digital pulses. Refer to figure 97. The number of and time between pulses are counted by a Microprocessor which in turn controls the McIntosh designed Precision Electronic Attenuator that provides 213 steps in 0.5dB increments and maintains the channel balance to within +

0.1dB. With most Preampli-

fiers the Volume Control is placed ahead of the Amplifying Circuitry, refer to figure 98 on the next page, example No.1. This design provides a great dynamic range and freedom from input overload, but the back-

Figure 97

ground noise level is higher especially at lower settings of the volume control. In example No. 2, by placing the Volume Control after the Amplifying Circuitry there is a reduction in dynamic range and input overload of the Preamplifier, but has the benefit of lower background noise levels. The only correct way to design a high performance Preamplifier is with two volume controls, refer to example No.3. This provides the benefits of wide dynamic range, freedom from Input overload and a background noise level that actu-

ally goes down as the volume control setting is reduced. The actual improvements in this McIntosh design achieve a noise floor of 118 dB, refer to figure

99. The special controlling circuitry for this dual volume control design is known as the McIntosh “Dynamic Control Multiplexer”.

Fully Balanced Circuitry

To compliment the level of performance achieved in one of McIntosh’s famous Power Amplifiers with Quad Balanced Circuitry, the C1000 Preamplifier also utilizes fully balanced circuitry. This design topology allows for the virtual cancelation of all forms of distortion, both audible and measurable, along with extremely low background noise levels.

In the typical Preamplifier, one set of circuits have to amplify the positive and negative going parts of the audio sound wave form. In the C1000, the implementa-

Signal to Noise (dB)

tion of fully balanced circuitry has the positive going

audio sound waves amplified by one set of circuits. In a similar manner the negative going audio sound waves are amplified by another set of circuits. Refer to figure 100. Audio signals connected to the unbalanced Inputs of the C1000 are first converted to a balanced signal before they are amplified. In a similar manner the balanced audio signals are converted to unbalanced signals before they are available to the unbalanced outputs jacks.

Moving Coil Preamplifier

One of the popular types of Phono Cartridges for Turntables used today are “Moving Coil”. Due to their design, the Moving Coil Cartridge’s output voltage is typically in the range of 300 to 500 microvolts (millionth of a volt) and thus requires additional amplification in order to match the output voltage of a “Moving Magnet/Induced Moving Magnet” cartridge type with 2.5 to 10 millivolts (thousandths of a volt). The lower the output voltage of the cartridge, the greater the level of amplification required and thus the greater potential for higher noise levels being generated by the circuitry.

McIntosh has designed a new Totally Shielded Moving Coil Preamplifier Module using special ultra low noise circuitry with out the need for a step-up transformer. Refer to figure 101. The C1000 utilizies a double filtered power supply design, just for the Moving Coil Preamplifier Module. It offers the ability to change the input impedance from 25

Technical Description, con’t

ohms to 1000 ohms in six steps to match a wide variety of Moving Coil Cartridges.

Logic Controlled Circuitry

All Inputs, Outputs, Data Ports, Power Control Outputs and Trigger Outputs are controlled by Logic Circuits in the C1000C. The microprocessor is the heart of the Logic Circuits and is controlled by McIntosh developed software. It implements all commands received from the Front Panel Controls or the supplied Re-

mote Controls and indicates them on the Alphanumeric Display. Refer to figure 102. When McIntosh Source Components are connected to C1000C Data Ports, basic command functions from the C1000 Remote Control are passed on to those components, thus allowing one Remote Control to operate an entire McIntosh Audio System. The Logic Circuits sense when both the C1000P and C1000T Preamplifiers are connected to the C1000C, at which time the C1000 functions as if it was one Preamplifier with 18 Inputs.

Figure 102

Meter and Circuitry

The lack of accurate performance in ordinary meters has presented difficult and complex problems. Ordinary meters are incapable of indicating the short interval information in a sound wave. Refer to figure 103 on the next page. The mass of the meter movement is too great to respond to the nearly instantaneous changes in music program material. That short interval information can have a duration less than as one-half of one thousandth of a second. Even if the

Figure 101

Technical Description, con’t

meter were capable of such high velocity movement, the human eye could not perceive the displayed information. McIntosh solved both problems electrically. By developing electronic circuits the meters are

Figure 103

made to respond to short intervals with an accuracy of 95%! To permit the eye to see such high speed motion, the electronic circuits that drive the meter pointer are time stretched. Special logarithmic circuitry allows the meter to indicate a 60dB plus range, without resorting to a Meter Range Switch.

Most owners desire one power switch for the whole audio system. The C1000 Controller is equipped with circuits providing remote Power Control On/Off signals to McIntosh Source Components and Power Amplifiers. When the C1000C is switched On, a digital “1” (+5V) signal changes the operational state of digital control circuitry and a DC voltage is sent to the Power Control Main Jacks. There are also special Power Control Jacks (Triggers and Passthru) and together with options in SETUP allow for the customizing of the Power Control Control Signals In for specific functions.

Power Supply Circuits

To compliment the design of the C1000, there are two indentical fully regulated power supplies, one for each channel. The Power Supply is designed to allow both the C1000P and C1000T Preamplifiers to be connected to the C1000C simultaneously. The C1000 Contoller contains the low and high voltage regulated power supplies for each channel. The special “R” core transformers, one for each channel, supply the necessary voltage/current for the low and high voltage regulated circuitry and are housed in shielded enclosures. Refer to figure 104.
