9
8 AES/EBU IN
• Digital audio stream from professional audio sources can be
connected to this XLR connector. For high-end sources with higher
sampling rates like 176kHz and 192kHz, it is highly recommended
that such sources be interfaced with the AES/EBU IN connector. The
AES/EBU IN is well suited to handle such sources with high sampling
rate.
• The source will appear as “AES/EBU” in the navigation drawer of the
BluOS App.
9 SUBWOOFER OUTPUT – SINGLE-ENDED 1-4
• Connect SUBWOOFER OUTPUT SINGLE-ENDED 1, SINGLE-ENDED
2, SINGLE-ENDED 3 and SINGLE-ENDED 4 to the low level input of
corresponding powered subwoofers.
• Low frequency information below the selected crossover setting is
sent to the connected subwoofer.
10 RS 232
· NAD is an integration partner with several smart control and
automation systems like Control4, Crestron, LUTRON among others.
Check out NAD website for a list of NAD’s integration partners. See
your NAD audio specialist for more information.
• Connect this interface using RS-232 serial cable (not supplied) to
any Windows compatible PC to allow remote control of M66 via
compatible external controllers.
• Refer to NAD website for information about RS232 Protocol
documents and PC interface program.
11 IR IN
· This input is connected to the output of an IR (infrared) repeater
(Xantech or similar) or IR output of another compatible device to
allow control of the M66 from a remote location.
12 +12V TRIGGER IN 1, IN 2, OUT
+12V TRIGGER OUT
• The +12V TRIGGER OUT is used for controlling external equipment
equipped with a +12V trigger input.
• Connect this +12V TRIGGER OUT to the other equipment’s
corresponding +12V DC input jack using a cable with 3.5mm male
plug.
• This output will be 12V when the M66 is ON and 0V when it is either
OFF or in standby mode.
13 SUBWOOFER OUTPUT – BALANCED 1-4
• Connect SUBWOOFER OUT BALANCED 1, BALANCED 2, BALANCED
3 and/or BALANCED 4 to the low level input of corresponding
powered subwoofers.
• Low frequency information below the selected crossover setting is
sent to the connected subwoofer.
14 POWER
• Supplies the AC mains power to the M66.
• When the rear panel POWER switch is switched ON, the unit will
automatically turn ON (operating mode) - Status Indicator (NAD
logo) will turn red, touch panel display will activate and then Status
Indicator (NAD logo) will turn white. It is not necessary to press the
front panel o(Standby) button.
• If you do not intend to use the M66 for long periods of time (such as
when on vacation), switch off the POWER switch.
• With rear panel POWER switched off, neither the front panel
o (Standby) button nor SRM1 remote control’s [ON] button can
activate the M66.
15 PHONO MC
• Input for a Moving Coil phono cartridge. Connect the twin RCA
lead from your turntable to this input if you are using a Moving Coil
cartridge.
16 PHONO GROUND CONNECTOR
• Turntables normally includes a single wire earth lead. Use the M66
phono ground connector to connect this lead.
• Unscrew the terminal to expose the hole, which will accept the lead.
After insertion, tighten the terminal to secure the lead.
17 PHONO MM
• Input for a Moving Magnet phono cartridge. Connect the twin RCA
lead from your turntable to this input if you are using a Moving
Magnet cartridge.
18 LINE IN 1, IN 2
• Input for line level sources such as CD player, tuner or any
compatible devices. Use dual RCA-to-RCA cable to connect the
source device’s left and right “Audio Output” to these line input
ports.
• The sources will appear as “Line 1” and “Line 2” in the navigation
drawer of the BluOS App.
19 BALANCED IN
• Connect XLR audio source to these connectors. Ensure that proper
pin configurations are followed – Pin 1: Ground, Pin 2: Positive
(signal live) and Pin 3: Negative (signal return).
• Digital audio stream from professional audio sources can be
connected to this XLR connector. For high-end sources with higher
sampling rates like 176kHz and 192kHz, it is highly recommended
that such sources be interfaced with the AES/EBU IN connector. The
AES/EBU IN is well suited to handle such sources with high sampling
rate.
• The source will appear as “Balanced In” in the navigation drawer of
the BluOS App.
20 ANALOG AUDIO OUTPUT (BALANCED)
• Use the ANALOG AUDIO OUTPUT (BALANCED) if the external source
to be connected has BALANCED audio input.
• Superior audio quality is ensured with the distinctive noise
reduction capability of BALANCED connection with XLR jacks.
21 ANALOG AUDIO OUTPUT (SINGLE-ENDED)
• Use single-ended ANALOG AUDIO OUTPUT (SINGLE-ENDED) for
sources that are not equipped with BALANCED analog audio input.
• Use a twin RCA-to-RCA lead to connect ANALOG AUDIO OUTPUT
(SINGLE-ENDED) to the corresponding analog audio input of
compatible devices such as amplifiers, receivers or other applicable
devices.
IMPORTANT
There is no audio output at ANALOG AUDIO OUTPUT (BALANCED and
SINGLE-ENDED) if
• Headphone is connected to HEADPHONES jack in the front panel.
• M66 is at Bluetooth Headphones mode.
22 FUSE HOLDER
• Only qualified NAD service technicians can have access to this fuse
holder. Opening this fuse holder may cause damage thus voiding
the warranty of your M66.
