IDENTIFICATION OF CONTROLSFRONT PANEL1 STANDBY LED: This indicator will light up amber when M2 is instandby state. When M2 is at ON state, this indicator will illuminate blue.2 STANDBY BUTTON: Press this button to switch ON the M2. TheStandby LED indicator will turn from amber to blue and illuminate theVFD. Pressing the STANDBY button again turns the unit back to standbymode.IMPORTANT NOTICEThe rear panel POWER switch must be set to ON position for theSTANDBY button to activate. After pressing the STANDBY button, therewill be a delay before the M2 will be completely enabled. Please waituntil the initial “NAD M2” display in the VFD is extinguished before youselect any of the source input or features of your M2.3 VACUUM FLUORESCENT DISPLAY (VFD): Display visual informationabout the selected source input, menu options, volume level and otherrelated information and settings.4 VOLUME: Use this control to adjust M2’s overall amplification or volumelevel. Turn clockwise to increase the volume setting; counter clockwiseto lower it. The M2 features a “velocity sensing” volume control; rapidmovement changes the volume in large steps, slow movement incrementsthe volume in 0.5dB steps. The VOLUME knob is also used to select optionsor adjust settings when MENU button is activated.5 COAX 1: Select the source connected to the COAX 1 rear panelterminal as the active input.6 COAX 2: Select the source connected to the COAX 2 rear panelterminal as the active input.7 OPTICAL 1: Select the source connected to the OPTICAL 1 rear panelterminal as the active input.8 OPTICAL 2: Select source connected to the OPTICAL 2 rear panelterminal as the active input.9 AES/EBU: Select the source connected to the AES/EBU IN rear panelconnector as the active input.10 BALANCED: Select the source connected to the BALANCED L andBALANCED R rear panel connectors as the active input.11 SINGLE-ENDED: Select the source connected to the SINGLE-ENDED Land SINGLE-ENDED R rear panel terminals as the active input.12 LOOP (DIGITAL PROCESSOR LOOP): Allow the insertion of externaldigital filters into the signal path. This is the digital equivalent of theanalog “Tape Monitor Loop”. An example on how to take advantage ofthis feature is illustrated below.a Connect a digital input to the rear panel’s OPTICAL 1 TosLink opticalterminal.b Connect the rear panel’s OPTICAL LOOP OUT to a compatibleOPTICAL IN of a Mac or any processor where the signal can besubjected to a wide library of crossover filters, equalization or roomcorrection programs (Check if your Mac or processor has thesefeature capabilities).c Send out the processed signal from your Mac or processor’scorresponding Optical Out port into M2’s OPTICAL LOOP IN therebycompleting the signal loop path.d Press front panel’s “loop” button to select your OPTICAL 1’s“processed” input signal. When “loop” feature is engaged, “LOOP” willbe continuously displayed at the lower left corner of the VFD after abrief display of sample rate setting of the source.IMPORTANT NOTICEWith “loop” button enabled, there will be no audio output if anyconnection from the above “loop” setup example is “broken” (i.e., noconnection to OPTICAL OUT, not looped to “OPTICAL LOOP IN”, etc). Press“loop” button again to deactivate or turn off the “loop” feature (“LOOP”is extinguished in the VFD) thus returning to normal audio listening of aselected source input.NOTEThis digital processor loop feature can be applied to all analog anddigital audio input signal sources (Optical 1-2, Coax 1-2, AES/EBU,BALANCED and SINGLE-ENDED).1765 84329 10 11 12 136ENGLISH FRANÇAIS ESPAÑOL ITALIANO DEUTSCH NEDERLANDS SVENSKA РУССКИЙ
