IMPORTANT SAFETY INSTRUCTIONS 12 Grounding or Polarization - This product may be equipped with a polarized alternating-current line plug (a plug having one blade wider than the other). This plug will fit into the power outlet only one way. This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit, contact your electrician to replace your obsolete outlet. -

PRESENCE OF IMPORTANT OPERATING AND MAINTENANCE (SERVICING) INSTRUCTIONS IN THE LITERATURE ACCOMPANYING THE APPLIANCE CAUTION Changes or modifications to this equipment not expressly approved by NAD Electronics for compliance could void the user’s authority to operate this equipment. CAUTION REGARDING PLACEMENT To maintain proper ventilation, be sure to leave a space around the unit (from the largest outer dimensions including projections) equal to, or greater than, shown below. - Page 5 About the M3 Dual Mono Integrated Amplifier: ANALOG SOUND, DIGITAL CONTROL The M3 is NAD's concept of the ideal musical companion, capable of transporting the listener to that place where the music simply exists in its own perfect space. For this task we have pushed classical analog circuit design to unprecedented levels of performance.
- Page 6 NAD's patented current amp output stage starts with < 0.02 % static and dynamic distortion open loop (before feedback); even into 3 ohms at 20-20k at all levels. By utilizing small amounts of feedback the circuit returns distortion levels at all audible frequencies that are at limit of measurement - less than 0.002%!

- Page 13 Setup About the M3 Dual Mono Integrated Amplifier 8. REC/Z2: This output is a steady state line-level output. Connect this output to recording equipment such as an audio tape deck or an A/D Converter recorder. One may also connect this output to an auxiliary piece of audio equipment such as an integrated amplifier for multi-zone operation.
- Page 14 +12V TRIGGER OUT interface. 14. RS-232: Using a Windows® operating system personal computer, one can remotely control the M3 with NAD's proprietary interface control software. This remote control facility employs a functional image of the M3's front panel as the GUI (graphical user interface).

Page 15: Operation
The Remote Control handset handles all the key functions of the M3 and has additional controls to remotely operate both NAD DVD and CD machines (see CD/DVD Switch below). It will operate up to a distance of 16ft (5m). Alkaline batteries are recommended for maximum operating life. - Page 16 11. DVD/CD Switch: Inside the battery compartment is a selection switch for the M3 remote control (see figure 4). Position 1-setting controls the NAD DVD-players while position 2- setting controls NAD CD-players. Using a paper clip, select either position 1 or 2 taking care not to damage the switch with excessive force.
