M3 10262005.qxd 1/3/2006 2:49 PM Page 2 IMPORTANT SAFETY INSTRUCTIONS IMPORTANT SAFETY INSTRUCTIONS • Save these instructions for later use. • Follow all warnings and instructions marked on the audio equipment. ENGLISH 1 Read instructions - All the safety and operating instructions should be read before the product is operated. 2 Retain instructions - The safety and operating instructions should be retained for future reference.
M3 10262005.qxd 1/3/2006 2:49 PM Page 3 IMPORTANT SAFETY INSTRUCTIONS ENGLISH 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.

THE LIGHTNING FLASH WITH ARROWHEAD SYMBOL, 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.
M3 10262005.qxd 1/3/2006 2:49 PM Page 5 Introduction About the M3 Dual Mono Integrated Amplifier: ENGLISH 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.
M3 10262005.qxd 1/3/2006 2:49 PM Page 6 Introduction About the M3 Dual Mono Integrated Amplifier: ENGLISH The volume attenuator is very unique in that it uses discrete 1% precision resistors that keep impedance (and noise) very low. It is arrayed in 3 stages to reduce the residual noise in each amplifying stage and prevent the 'cascade effect' of noise that is present in most preamp designs.
M3 10262005.qxd 1/3/2006 2:49 PM Page 7 Introduction About the M3 Dual Mono Integrated Amplifier: MAIN FEATURES: • Discrete high input impedance balanced input amp with greater than 70dB Common Mode rejection ratio across the entire frequency range. ENGLISH • High input impedance class-A amplifiers in the main signal path. • Proprietary stepped-distributed low impedance volume control for ultra low noise/distortion at all volume levels.

Standby Button: The Standby Button turns on and to standby the M3. This button will only function when the Status Condition LED is either blue representing the on-state, or amber representing the standby state. FRANÇAIS 2. Status Condition L.E.D.: Standby: When this L.E.D. is amber the M3 is in the standby state. On: When this L.E.D.
M3 10262005.qxd 1/3/2006 2:49 PM Page 11 Identification of controls About the M3 Dual Mono Integrated Amplifier 6. mode: The mode selector function is a convenient way to test the set up of the M3. For example, use the Mono mode to check the speakers phase. Setting the mode to Left or Right allows one to easily balance left signal inputs with right signal inputs. 7. balance: Adjust LEFT and RIGHT balance simultaneously using the volume (set up) control.

M3 10262005.qxd 1/3/2006 2:49 PM Page 13 Setup About the M3 Dual Mono Integrated Amplifier ENGLISH 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. In such a case, use this output in conjunction with the ZR3 remote control and IR IN.
M3 10262005.qxd 1/3/2006 2:49 PM Page 14 Setup About the M3 Dual Mono Integrated Amplifier: ENGLISH 12. IR OUT 1: The IR OUT 1 is hard-wired to the M3's IR (infrared) sensor. Use this 3.5 mm mini-jack connector to pass commands form the M3's front panel IR sensor to other units with similar IR connectors. Daisy-chain the M3's IR OUT 1 to other hi-fi system components' IR inputs to other IR outputs so that control of a whole system is via the M3's front panel IR sensor.
