6 BRIDGE MODE
The M33 amplier can be congured to be MONO (Bridge Mode),
more than doubling its output power. This way, the M33 can be used
as part of a high power stereo or home-theatre system, by connecting
additional power ampliers.
• In BRIDGED MODE (switch at ON (MONO) setting), the M33 will
produce approximately 640W into an 8 ohm loudspeaker. In this
mode, the amplier sections will react as though the speaker
impedance has been halved. Low impedance speakers (under 8
ohms) are not recommended when using Bridge Mode as these
may cause the amplier’s thermal cut-out to operate if played at
high levels.
• Set the BRIDGE MODE switch to the “ON (MONO)” position and
connect the speaker to the terminals marked “L +” and “R-” ensuring
that the “L+” is connected to the “+” terminal of your speaker and
the “R-” is connected to the speaker’s “ - ” terminal.
• Connect the source to the Left input sockets only. Do not connect
anything to the Right Input socket when Bridge Mode is selected.
7 RS 232

are connected to coaxial or optical input ports.
7 A/V Mode: By connecting your TV or other video sources to your
M33 through coaxial, optical or HDMI input ports, you can listen to
your favorite shows or movies through your BluOS system. Grouping
multiple BluOS devices from one of these inputs can require
an abundance of network trac. A/V mode creates a short and
unobtrusive buer to your audio to ensure your BluOS system stays in
sync with your video even with slower or cluttered networks.
Enabled: With A/V Mode enabled on your input source, audio delay
will be automatically adjusted to keep your grouped BluOS devices
in sync with the video source connected. Use the Lip-sync delay
option below the A/V Mode setting to manually select the delay
time to better suit the speed of your network.
Disabled: When your M33 is connected to an audio source without
video, such as a turntable or CD player, the A/V Mode setting
should be disabled.
8 Lip-sync delay: With A/V Mode enabled, “Lip-sync delay” can be
adjusted to ensure your audio is staying in sync over your network
with the original video source. By varying “Lip-sync delay” from 50ms to
150ms, one can delay the audio output to synchronize it with the video
image of the corresponding source.
9 Hide Source: Activate or deactivate selected Source
10 ADC Sample Rate (applies to Analog Sources only)
An analog audio input is converted to digital signal by making use of
M33’s superb circuitry called analog-to-digital converter (ADC).
Using this ADC Rate feature, the sampling rate of the resulting digital
audio signal ((available when using BluOS multi-room streaming)) can
be converted into three levels - 48K, 96K and 192K. Make sure that the
associated equipment will be able to handle the applicable digital
audio signal level.
11 Analog Gain (applies to Analog Sources only)
Gain adjustment allows all sources to play back at the same volume
level so you don’t need to adjust the volume every time a new source
is selected. It is generally preferable to reduce the level of the loudest
source rather than making louder the softer sources.
12 Phono Type (applies to Phono Sources only)
Select either MM (moving magnet) or MC (moving coil) depending
upon the connected turntable’s phono cartridge.

The NAD HTRM 2 is ready to operate the M33 right out of the box, but it is really eight remotes in one.
Each of the 8 Device Selector keys at the top of the handset can call up a new “page” of remote control
codes to be transmitted by the remaining keys. You may “teach” codes from any infrared-remote
controlled component, regardless of brand, to any or all of these.
Obviously, the most logical system is that you teach the codes from your BD player to the [BD] Device
Selector “page,” your television’s codes to the [TV] “page,” and so on, but there is no required scheme:
You may load any commands to any key on any page (see“Learning Codes From Other Remotes,”
below).
The HTRM 2 is already preprogrammed with a full complement of commands for the M33 on its
[AMP] Device Selector page, and as well as with library commands to operate most NAD-brand CD,
BD or DAC components on the corresponding Device Selector “pages.”These default commands are
permanent: Even if you teach the HTRM 2 new commands to take their place, the underlying library
commands remain in place and can easily be recalled should you add an NAD component to your
system later (see “Delete Mode”, below).
Note: For use with the M33, it should not be necessary to re-program any keys on the HTRM 2 [AMP]
page. However, in order for the HTRM 2 to control your specic NAD-brand components you may
need to load one or more dierent code-libraries (see “Loading Code Libraries,” below).
CONTROLLING THE M33
The HTRM 2 is divided into two main sections. Eight Device Selector keys at the top—[AMP], [MP,]
[TV,] and so on—set the handset’s remaining keys to a “page” of commands to control a particular
component. A Device Select key determines only what component the HTRM 2 will command; it
does not perform any function on the M33. All of the remaining keys are function keys that can “learn”
control codes from virtually any infrared remote controller, allowing you to teach the codes of your
equipment, regardless of brand, to the HTRM 2.
However, the HTRM 2 is already preprogrammed to operate the M33. All of the function keys on the
[AMP] Device Selector “page” perform M33 functions. (The HTRM 2 can also command many other
NAD components, from its [CD], [BD], [DAC] and [CUSTOM] pages.)
It is important to note that certain HTRM 2 keys perform dierent functions depending on the selected
Device Selector “page.”

LEARNING CODES FROM OTHER REMOTES
Begin by positioning the HTRM 2 “nose-to-nose”with the source remote so
the two devices’infrared windows are about 2 inches apart.
1 Enter Learning Mode: On the HTRM 2, simultaneously press-and-hold
for 3 seconds both a Device Selector key and the [RES] key until the
Learn LED (located between HTRM 2’s ON and OFF buttons) turns
steady green.
2 Press the HTRM 2’s function key you wish to teach a command; the
Learn LED will turn amber.
3 Press-and-hold the function key on the source remote: The HTRM 2’s
Learn LED will icker amber for a second or two, then turn solid green.
The command is learned.
4 Press the HTRM 2’s Device Selector key again to exit the learning mode.
If the Learn LED does not icker amber you may need to vary the distance
between the remotes. If the Learn LED turns red instead of green, the
source remote command could not be learned on that attempt.
Example: Learning “BD Pause”
Position the HTRM 2 and your BD player’s remote as described above.
1 On the HTRM 2, simultaneously press-and-hold [BD] and [RES]; the
Learn LED turns steady green.
2 Press the HTRM 2’s Pause [ j ] key; the Learn LED turns amber.
3 Press-and-hold the corresponding Pause key of your BD player’s remote
control; the HTRM 2’s Learn LED ickers amber and then turns solid
green. The command is learned.
4 Press [BD] again to exit the learning mode.
NOTES
• The DEVICE SELECTOR keys can themselves be congured to learn commands.
• Press and hold a congured DEVICE SELECTOR for at least 2 seconds to
execute a function assigned to the particular DEVICE SELECTOR key.
• A short press of a congured DEVICE SELECTOR will just switch the active device.
CANCEL OPERATION
You can cancel conguring a key, by pressing the active Device Selector
key before the learn process is complete; the Learn LED will turn red.
PUNCH THROUGH
The HTRM 2’s “punch-through” function allows you to retain a function key
from one Device Select “page”to another, so that, for example, the AMP
[SURR MODE] function might still control the M33 when the BD Device
Selector page is active.
NOTE
The HTRM 2’s [VOL R/T] keys are pre-programmed as “punched-
through” for all Device Selector pages: [VOL R/T] will operate the
M33’s master-volume regardless of the currently selected device. The
[SURR] [CENT] and [SUB] Channel Volume controls similarly are pre-
programmed as punched-through.
SET A PUNCH THROUGH
1 Enter Learning Mode and press the desired button to be punched
through.
2 Press twice the Device Selector button of the destination device. The
status LED will turn green.
3 Press the Device Selector button again to exit Learning Mode.
Example: Punch-through AMP [SURR MODE] key to the BD “page”
1 On the HTRM 2, simultaneously press-and-hold [BD] and [RES]; the
Learn LED turns steady green.
2 Press [SURR MODE]; the Learn LED turns amber.
3 Press [AMP] twice; the Learn LED turns green.
4 Press [BD] again to exit the learning mode.
COPY A COMMAND FROM ANOTHER KEY
You may copy a command from any HTRM 2 key to any other key.
COPY A KEY FUNCTION
1 Enter Learning Mode.
2 Press the key that will contain the copied key. The Learn LED turns
steady amber.
3 If the key to be copied resides on another “page”, press rst the
corresponding Device Selector key and then press the desired key to
be copied. The Learn LED turns steady green.
4 Press the Device Selector key again to exit Learning Mode.
Example: Copy the Pause command from the CD page to the AMP [ j]
button:
1 On the HTRM 2, simultaneously press-and-hold [AMP] and [RES]; the
Learn LED turns steady green.
2 Press Pause [ j] ; the Learn LED turns amber.
3 Press [CD]; press Pause [ j] ; the Learn LED turns green.
4 Press [AMP] again to exit the learning mode.
NOTE
The copy and punch-through functions are similar. However, if you
copy a command and then subsequently delete, or over-write the
original (source-key) command , the copied-to key’s command remains
unchanged. If you punch-through to a command and then delete or
over-write the original key, the punched-through functions also change
accordingly.
MACRO COMMANDS
A “macro”command is a series of two or more remote codes issued
automatically from a single keypress. You might use a macro to automate a
simple command sequence, such as,“Turn on the BD player and then press
PLAY”. Or you might compose an elaborate macro to power up an entire
system, select a source, choose a Listening Mode, and begin playback—
again, all from a single keypress. Each DEVICE SELECTOR and function keys
of the HTRM 2 can be stored into one macro.
NOTE
Macros are independent of the currently selected device.
RECORDING MACROS
1 Simultaneously press-and-hold the [MACRO] key and the HTRM 2
function key to be assigned the macro until the status LED turns green.
The macro button will also light up.
2 Press the sequence of function keys to be recorded into the macro.
3 Be sure to press rst the required Device Selector key for each function
(you may switch devices while recording the macro as many times as
necessary), allowing you to create macro containing commands from
more than one Device Selector “page.”
4 After entering the desired command sequence, press [MACRO] again to
store the macro; the Learn LED and [MACRO] key illumination will turn
o.
OPERATION
USING THE HTRM 2 REMOTE CONTROL

ENGLISH
21
Example: Record a Macro to the [0] key to Turn on the M33.
1 Select “Input 1” (Source 1), and commence playback of connected
Source 1 device (as in BD player).
2 On the HTRM 2, simultaneously press-and-hold [MACRO] and [0]
(numeric zero); the Learn LED turns steady green.
3 Press [AMP]; press [ON]; press [1] (“Input or Source 1”); press [BD]; press
[4] (Play) - the Learn LED blinks as each step is added.
4 Press [MACRO] again to exit the macro-record mode.
To clear a macro, perform the above steps without entering any functions.
NOTE
Each macro can store a maximum of 64 command steps. If you exceed
this number, the macro will be stored automatically after the 64th
command is added.
EXECUTING MACROS
1 Press and release [MACRO]; its key lights for 5 seconds. While it remains
lit, press an HTRM 2 key where a macro has been stored.
2 The corresponding macro will run; as each step executes, its “parent”
Device Selector’s key ashes briey.
3 When nished, the [MACRO] key illumination goes out.
Pressing any other HTRM 2 key while a macro is executing will abort the
macro. Remember that you must hold the HTRM 2 so that its infrared
emitter can activate the target components.
NOTE
When a macro executes, a 1 second delay is automatically inserted
between its commands. If you need more than a 1 second delay
between particular commands—for example, to permit a component
to power up completely—you can record “empty” steps into the macro
by changing Device Selector “pages” without entering actual command
functions.
KEY ILLUMINATION TIMEOUT
The HTRM 2’s key-illumination can be set to remain lit for 0-9 seconds. The
default value is 2 seconds.
SET THE ILLUMINATION TIMEOUT
1 Simultaneously press and hold the HTRM 2’s [DISP] and the [0-9] key
corresponding to the desired timeout duration.
2 The Learn LED will ash twice to conrm the new setting.
3 When set to zero, the illumination will not turn on at all.
NOTES
• Key illumination is activated when one presses any HTRM 2 key.
• If HTRM 2 senses movement, key illumination is activated without
having to press a key. If HTRM 2 is shaken, key illumination is also
activated.
• Key illumination is the biggest drain on the HTRM 2’s batteries. A short
key illumination timeout will extend battery life appreciably; turning it
o altogether (set it to 0 seconds) will lengthen it still further.
CONFIGURING KEY ILLUMINATION
Keys to Press (for 3 seconds) Mode
DISP + Digit Key (0-9) Set key illumination timeout to number of
seconds corresponding to digit key. Zero turns o
the key illumination entirely.
DISP + OFF Disable light sensor. Key illumination will turn on
with any key press.
DISP + ON Enable light sensor.
DISP + ENTER Set the light sensor threshold to the current
light level.
DISP + RTN Restore all key illumination settings to the
defaults.
FACTORY RESET
The HTRM 2 can be reset to its factory state, deleting all learned
commands, copied and punched-through keys, macros, and other setup
information, reverting all keys to their pre-programmed library commands.
PERFORM A FACTORY RESET
1 Simultaneously press-and-hold the HTRM 2’s [ON] and [RTN] keys for 10
seconds. The Learn LED will start to ash green.
2 Release [ON] and [RTN] before the second ash is complete; the Learn
LED will turn red, indicating the remote has been reset.
NOTE
Release [ON] and [RTN] before the second ash goes out; otherwise, the
unit will not reset. Should this occur, repeat the full procedure.
DELETE MODE
The HTRM 2 can store learned, copied, and “default library” commands on
any single key. The default library commands are the pre-programmed
NAD codes, such as the native M33 commands on the [AMP] page.
You can delete commands by layers back“down”to the default library
command on any key, removing learned commands, punched-through
functions, and copied keys.
NOTE
The default library commands cannot be deleted.
ENTER DELETE MODE
1 Simultaneously press-and-hold the desired key’s Device Selector key
and the [RTN] key for 3 seconds, until the Learn LED turns green.
2 Press the function key whose command you wish to delete; the Learn
LED ashes; the number of times indicates which type of function has
become active - see the table below.
3 Press the active Device Selector key again to exit Delete Mode.
