The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. WARNING - TO REDUCE RISK OF FIRE OR ELECTRICAL SHOCK, DO NOT EXPOSE THIS EQUIPMENT TO RAIN OR MOISTURE. NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED PERSONNEL. To prevent the risk of electric shock, do not remove cover or back. No user serviceable parts inside. IMPORTANT SAFETY INSTRUCTIONS! PLEASE READ THEM BEFORE OPERATING THIS EQUIPMENT. 1. [. . . ] The Data Port Input allows Remote Control Operation from another McIntosh Component. The IR Input allows for the connection of an IR Receiver. · Remote Control Operation · Special Analog Filter and Output Amplifier The third order Butterworth gentle slope analog filter removes any remaining digital artifacts from the output signal. The low impedance Output Amplifer drives both the Balanced and Unbalanced Output Connections. Balanced and Unbalanced Outputs Balanced connections guard against induced noise and allow long cable runs without compromising sound quality. There are also Unbalanced connections for components without Balanced Inputs. Precision Tracking Volume Control Volume levels are controlled by a Precision Digitally Controlled Attenuator System with a tracking accuracy of 0. 1dB. Alphanumeric Fluorescent Display The Multifunction Front Panel Display indicates the Source Selection, Volume Levels and the Setup Mode Selections. Digital Inputs with Title Reassignment The MDA1000 has provisions for three Coaxial Digital In- A Remote Control is included that allows for complete control of major functions. · · Glass Front Panel The famous McIntosh Illuminated Glass Front Panel with a three dimensional look ensures the pristine beauty of the MDA1000 will be retained for many years. Fiber Optic Solid State Front Panel Illumination 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 Side of the MDA1000 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 MDA1000's circuitry. Special Power Supply A fully regulated Power Supply with a special R-Core Power Transformer, ensures stable noise free operation even though the power line varies. 5 · · · · · · Dimensions Dimensions The following dimensions can assist in determining the best location for your MDA1000.

Data Control Connections facilitate the ability to remotely operate McIntosh Source Components using the supplied MDA1000 D/A Converter Remote Control or the McIntosh Control Center/Preamplifier Remote Control. Connect a Power Control Cable from the MDA1000 POWER CONTROL IN Jack to the appropriate Power Control Out Jack on the McIntosh Control Center/ Preamplifier. Note: If the MDA1000 is connected to a McIntosh MCD1000 CD Transport in a system without a McIntosh Control Center or Preamplifier, the MDA1000's Power Control In should be connected to the MCD1000 Power Control Out Jack. McIntosh Controller 2. Connect a Power Control Cable from the MDA1000 POWER CONTROL OUT Jack to the McIntosh MCD1000 CD Transport Power Control In Jack. Optionally, connect a Power Control Cable from the MCD1000 Power Control Out Jack to the McIntosh CD Player Power Control In Jack. Connect a Data Control Cable from the MDA1000 DATA IN Jack to the LINE 1 Data Port on the McIntosh Control Center/Preamplifier. Connect a Data Control Cable from the MDA1000 DATA SWITCHED DATA OUTPUTS Jack 1 to the McIntosh MCD1000 CD Transport Data In Jack. Connect a Data Control Cable from the MDA1000 DATA SWITCHED DATA OUTPUTS Jack 4 to the McIntosh CD Player Data In Jack. McIntosh CD Player McIntosh MCD1000 CD Transport 9 How to Connect for Audio How to Connect for Audio 1. Connect Audio Cables from the McIntosh MDA1000 Left and Right BALANCED AUDIO OUTPUTS to the McIntosh Audio Control Center/Preamplifier Line 1 Balanced Inputs. Note: The MDA1000's UNBALANCED Left and Right AUDIO OUTPUTS may be used instead of the BALANCED Connections. [. . . ] If the variable volume level has been selected in the Setup Mode (refer to page 12), use the LEVEL UP (+) or DOWN (-) Push-button on the remote control to adjust the MDA1000 Volume level. 15 How to Operate the MDA1000 The McIntosh MDA1000 D/A Converter has been factory configured for operating settings that allow immediate enjoyment of superb high fidelity audio without the need for further adjustments. If you wish to make changes to the factory default settings, refer to the SETUP Section of this Owner's Manual starting on page 12. Press the POWER Switch to ON, the Red LED above the STANDBY/ON Push-button lights to indicate the MDA1000 is in Standby Mode.
