[. . . ] D/A Converter MDA1000 Owner's Manual McIntosh Laboratory, Inc. 2 Chambers Street Binghamton, New York 13903-2699 Phone: 607-723-3512 FAX: 607-724-0549 The lightning flash with arrowhead, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. 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. There is also a Volume Control Bypass Mode for a fixed output level. Alphanumeric Fluorescent Display The Multifunction Front Panel Display indicates the Source Selection, Volume Levels and the Setup Mode Selections. The displays intensity is fully adjustable. 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. Refer to information on the back panel to determine the correct voltage DATA PORTs send signals to compatible source components to allow remote control operation BALANCED AUDIO OUTPUTS contain analog stereo signals to connect to Balanced inputs of other components IR INPUT for connecting an IR Receiver DATA IN receives operating data from a McIntosh Control Center OPTICAL DIGITAL AUDIO INPUTS receive digital audio signals from source components UNBALANCED AUDIO OUTPUTs contain analog stereo signals to connect to Unbalanced inputs of other components POWER CONTROL IN receives turn-On signals from a McIntosh Component and POWER CONTROL OUT sends turn-On signals on to another McIntosh Component COAXIAL DIGITAL AUDIO INPUTS receive digital audio signals from source components Balanced DIGITAL AUDIO INPUT receives digital audio signals from the McIntosh MCD1000 CD Transport 8 How to Connect for Power Control and Data How to Connect for Power Control and Data The Power Control Connections facilitate the ability to switch power On and Off to the McIntosh Source Components automatically with the McIntosh Control Center/ Preamplifier. 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. [. . . ] If the BYPASS OFF Mode has been selected, the Front Panel Alphanumeric Display will also indicate "LEVEL __" between indications of "BYPASS OFF" and title of the Input selected. Refer to figures 13 and 14. Figure 13 Figure 14 Figure 10 Input Selection Select the desired Source with the Front Panel INPUT Control or using the appropriate the Push-buttons on the Remote Control. Volume Control When the BYPASS OFF Mode of operation has been selected, the Front Panel Level Control is active allowing for changes in the volume level. The remote control supplied with the MDA1000 will also allow for volume level changes by using the LEVEL Up (+) / Down (-) Push-buttons. [. . . ]
