Thank you!

Thanks for your investment in the Controller. We worked
hard to make the Controller easy and intuitive to use and
ultra-flexible to fit a variety of applications with state-of­the-art performance and features. In addition, the
Controller can offer performance beyond any component
of its type when used with NHT speakers and amplifiers.
The reason for this is all the NHT speaker details have
been programmed into the Controller. The nuances of
this and levels of integration is better left for technical
papers that you'll find on our website nhthifi.com, and no
doubt reviews in enthusiast magazines.

Should you be using the Controller with non-NHT speak­er and amplifier systems, don't worry, you'll still realize a
level of performance, sophistication and control
previously unavailable. Please enjoy.

Since the Controller will have regular software updates
available, this user guide will be updated as well. Please
visit www.nhthifi.com for current updates of this user
guide.

Introduction

The Controller is a very sophisticated home theater
controller and it is the center and the heart of a high-end
audio/video system.

When NHT speakers and amplifiers are used with the
Controller, the system's performance is further optimized
and automated. For example, all NHT speaker parame­ters for bass management (high pass, low pass filters, eq
and phase) are programmed into the Controller. This fea­ture also eliminates as many as 20 setup screens.

All NHT components also feature the NHTBus which
allows smart control, communication, and status monitor­ing between components. This exclusive bus performs
tasks like switching the components in or out of standby
together and can even turn off any unused amplifier
channels, saving energy, reducing heat and improving
the performance of the active amplifier channels. The
Controller also features three 12VDC trigger outputs and
an RS-232 interface for compatibility with wide range of
home automation systems.

The Controller decodes Dolby Digital, DTS and DTS-ES
digital audio formats and has the latest audio processing
features like Dolby Pro Logic IIx. Naturally, the Controller
can also function as a High-End stereo preamplifier. In
addition, a 7.1 channel input is provided with compre­hensive volume and bass management facilities. This
ensures that the Controller will remain compatible with
new multi-channel formats to appear in the future.

For two channel audio sources the Controller can per­form mono downmixing, Pro Logic IIx and DTS Neo:6
decoding and add ambience with music modes. For
multi-channel analog sources the Controller can gener­ate the surround channels utilizing Dolby Digital EX or
DTS-ES Matrix processing. If desired, the discriminating
audiophile can bypass the digital section of the
Controller completely by connecting, for example, a
stereo source to the Left and Right channels of the 7.1
analog channel input.

For the quick setup, Auto Calibration automatically
calculates the correct speaker distances and level
settings.

(tape decks, VHS recorder, phono preamp, etc) here.

2. Analog audio outputs: In addition to the main 7.1
channel outputs, Controller has the following analog out­puts:



REC output: this mirrors the signal of the currently

selected analog input



Zone REC: this mirrors the currently selected

ZONE input.



ZONE output: is the signal currently selected by
the ZONE input. This output has separate volume con­trol capability from the main outputs.

3. 7.1 Channel input: This is multi-channel analog input,
where you can connect your multi-channel source, such
as an SACD or DVD-A player.

4. 7.1 Channel output: This is the main output section.
Use these terminals to connect to your amplifiers inputs.

5. Digital audio connections: Connect your digital
sources (DVD-players, CD-players) here. Coaxial and
optical type input terminals are available. One output
terminal is available, which mirrors the optical incoming
digital input stream.

Video Connections

The Controller supports four different video format types:
composite video, S-Video, component video and HDMI,
listed in order of increasing video quality. The basic rule
of thumb is to use always the best available connection
type to transport signals between devices.

To mix 'n' match different sources and display devices
with different input and output types, Controller supports
video format conversions. The following video format
conversions are available in the Controller unit:



Composite and S-Video inputs are available on

component and HDMI video outputs



S-Video inputs are available on HDMI, composite

and component video outputs



Component video inputs are only available on com-

ponent video outputs



HDMI inputs are only available on the HDMI output

Note: No scaling or de-interlacing are performed on any
incoming video input signal.

The Controller has the following video connectors:

6. Composite video inputs: Connect your video source
with composite output to these jacks.

7. Composite video outputs: Connect your display or
video recorder with composite video input to these jacks.

8. S-Video inputs: Connect your video source with S­Video output to these jacks.

9. S-Video outputs: Connect your display or video
recorder with S-Video input to these jacks.

10. Component video inputs: Connect your video
source with component video outputs to one of the com­ponent video inputs.

Note: Viewing any device connected to the component
video inputs requires you to connect the component
video output on the Controller to your video display
device.

8

11. Component video output: Connect your video dis­play device with component inputs to these jacks.

Note: One component video connection consists of three
RCA type jacks, as each one of the RCA jacks carries
one "component" of video signal.

HDMI Connections

12. HDMI audio/video inputs: Connect any video

sources equipped with HDMI outputs to these jacks.

13. HDMI audio/video output: Connect your display
device to this jack if so equipped.

Note: The Controller’s HDMI inputs and output support
standard, enhanced, or high-definition video, and Dolby
Digital, DTS and 2 channel PCM digital audio formats on
a single cable.

Note: To view any device connected to the HDMI video
inputs requires you to connect the HDMI video output on
the Controller to your video display device.

Note: The Controller’s "On Screen Display - OSD" is
available on the HDMI output! Y our display must be com­patible with 480i and 576i resolutions (standard NTSC
and PAL resolutions).

Note: Component video is NOT available on HDMI out­put at this time.

WARNING: HDMI capable displays should
only be connected to one of the HDMI out
connections. Connecting the display to the
HDMI In connection will cause serious dam­age to both the Controller and the display.

Control Connections

14. RS-232 serial port: This is a standard RS-232 com-

patible serial port. This port can be used to link Controller
in a home automation system or for software upgrades
and system setup with proprietary PC software.

15. IR inputs: Connect your infrared sensors here.
Controller supports Xantech and compatible infrared
repeaters with 1/8” mono connectors. An external power
supply is required for most IR sensors.

16. Trigger outputs: Triggers are 12V control lines,
which can be used to control and trigger other appliances
in your home theater setup (like screens and shades).
Usually these control power amplifier channels and turn
them off, when Controller is in standby mode. For more
details on this feature, see Trigger setup, page 28.

17. NHTBus: The NHTBus is the communication line
for NHT components. When connected together, such
functions as auto turn on, standby, muting of unused
amplifier channels and error reporting to the controller
happen automatically. Please note that this totally elimi­nates the need for the Trigger connectors when hooking
the Controller to any NHTBus component. If there is not
a sufficient number of NHTBus connectors available to
hook all the NHT components together, you can pur­chase a standard network (Ethernet) hub and use that as
the central connection point for all components.

The NHTBus uses a standard Ethernet network protocol.
When connected to your home network, DHCP capable
server or router, DHCP will automatically assign an IP
address to each component connected by the NHTBus.
More information about the NHTBus can be found on the
NHT web site www.nhthifi.com.

Tuner

18. Tuner antenna: Connect the FM (75 ohm) or AM

(300 ohm) antenna here to receive radio broadcasts with
your Controller’s built in AM/FM stereo tuner.

Power

19. Power inlet: Connect the supplied power cable to

this connector. The unit has a switch mode power supply
and accepts input voltages between 100 - 250 VAC.

Note: Do not turn main power off from the back of the
unit before switching into Standby mode from the front
panel or remote control. Failing to do so might cause loss
of the latest settings.

Front Panel

Front Panel Features

1. Standby switch: Use this switch to turn the unit ON

from STANDBY and vice versa.

2. Headphone output / calibration microphone input:

This jack has a dual purpose. Headphone jack accepts
any standard headphone with a 1/8-inch/3.5mm jack.
The jack also is used to connect the included calibration
micro-phone during level and distance calibration (see
section Speaker Setup, page 19).

3. 6 Function Select Touch Buttons: Functions of
these buttons appear as markings on the display window.
A light touch with your finger onto the button marking on
the surface is all that is required.

4. Mute: Turns on and off mute relays. If the unit is
muted, no audio signal passes to the main output
terminals.

5. Display: 2 x 20-character display provides informa­tion on the current system status. In normal operating
mode, information about current source, incoming signal
type, processing mode and volume level is available
simultaneously.

6. Touch Wheel: Volume control and navigation con­trol. To control volume, brush your finger around the
matte textured “donut” lightly and slowly . Moving your fin­ger clockwise increases volume and turning it counter­clockwise decreases volume. This control also is used as
a standard navigation control when in setup mode. Touch
the blue arrows for up / down / left / right and/or use the
"wheel" to select values.

Note: Unlike conventional electronics which use
electro-mechanical switches, the Controller uses soft
touch controls. In other words, don’t expect to hear a click
when you press buttons.

Note: Please be aware that the touch wheel is very
sensitive and can easily go to full volume very quickly
possibly damaging your speakers, amplifiers and ears
and startling your loved ones. Alight touch, with conser­vative movements is all that is required.

Proximity Feature

The Controller features proximity detection sensors. As
you move your hand towards the display window the
display wakes up and changes from the current status
(source, volume, listening mode and input type) to the
start screen (first three sources plus mode and setup)
When you move your hand have away, it returns to sta­tus mode (and after a few seconds the display goes
dark). The front panel display has two settings, “always
on” and “auto off”. When set to “auto off” the display will
go dark after 10 seconds (see Misc Setup / Display on
page 28).

If you have a door on your equipment rack which inter­feres with the proximity feature, the proximity feature can
be turned on and off (see Misc Setup / Proximity Mode,
page 28).

Setup and Menus

The Controller is very flexible and can be customized in
almost every aspect. In this chapter we go through the
Controller's menu system and look at how you can setup
your system to best suit your needs.

To get the most out of your audio-video system, carefully
read through this chapter. Even if someone else sets up
your system, it is good to know all the possibilities the
Controller can accommodate.

What can be done through the Menus?

The Main menu system is divided into the following
submenus:

NHT speaker wizard - If you own NHT speakers, the
Wizard automatically sets all the crossover frequencies
and assigns EQ (as needed) to any combination of NHT
speakers.

Speaker setup - Changes the Controller's speaker set­tings. You can also let Controller auto calibrate the set­tings. Both manual and automatic speaker calibration is
available.

Source setup - Changes the parameters of the ten pre­set Sources and the AM/FM Tuner.

Audio setup - Changes the processing mode parame­ters and tone controls.

Tuner setup - Lets you set the tuner presets and modes
like Auto or Manual tuning.

Trigger setup - There are three trigger jacks (i.e. exter­nal device controllers) on the back of the Controller and
this menu changes the setting of the triggers. Two of
them are programmable using this menu.

Misc setup - Lets you change things such as TV system
format, proximity mode and setup lock.

NOTE: By far, the easiest way to use the Controller's
menu is to connect a video monitor or TV to one of the
Video Out jacks on the unit (for more on connections, see
Video connections, page 8) and use the Controller’s
remote control to navigate the menus.

How to use the Menus with the Front Panel Controls
and On Screen Displays

As previously mentioned, using the remote control and
the OSD is the fastest and most intuitive way to use and
setup the Controller and thus highly recommended.

Note: Analog level indicators are not shown on the front
panel display and OSD is required for auto calibration
and the naming of sources. All other settings can be
accessed from the front panel.

Navigating the menus using the front panel controls

1. Wave hand near front panel or press any key adjacent

to the MENU text on the front panel display to start. The
text "Main menu" should now appear on the screen and
OSD.

2. Enter the Menu by pressing the right arrow key.

3. In the selected menu, do as before - select the desired

menu or submenu item by scrolling up and down with the
touch wheel’s up and down arrows (select with the right
arrow).

4. When all changes are made, press the menu button
again. Press the touch button adjacent to the EXIT on the
display if you want to exit without saving changes.

Navigating the menus with the remote control

1. Press MENU button to start. The text "Main menu"

should now appear on the Controller's front panel display
and OSD will additionally display the seven menu setup
options plus "Exit".

Note: Press ESC button on the remote at any time if you
want to exit without saving changes.

2. Select the menu you want to edit using the Up or Down
arrow button on the remote. The front panel display will
show the menu name on the top row and selected item
on the bottom row one at a time, while the OSD will show
a small arrow in front of the menu item. Press the OK
button to select the menu item.

3. In the selected menu do as before - go to the wanted
menu item or submenus with the Up and Down arrow
buttons and edit it with the remote control's Left and Right
arrow buttons.

14

4. When all of the changes are made, exit the menu by
navigating through the exit links. Pressing the MENU
button on the remote directly exits and saves the settings
from any menu level.

On Screen Display - Status

Pressing the STATUS button on the remote during
normal operation will display the status of the Controller's
Audio and Video assignments on the OSD.

The STATUS screen shows the currently selected
Source in the upper right corner (shown in our example
as DVD). The volume is displayed with a number range
from -90 to +20 (depending on the presets, levels and
tone controls as well as input signals) and a horizontal
line with a volume-tracking indicator that shows the
current volume relative position to the entire volume
range.

Audio Settings show the Signal type (examples: analog
or digital), selected Input jacks used (examples: Analog
1, Coax 2, HDMI) and Mode (examples: Stereo, Pro
Logic IIx Movie). Video Settings show the Input location
and type (examples: Component 1, HDMI 3, Analog 1).

NHT Speaker Wizard

The Controller has every current NHT speaker and
subwoofer model (and some older models too) factory
pre-programmed. This will allow your system to perform
at its very best while eliminating as many as 20 setup
screens and your need to perform the role of speaker
expert. The Wizard automatically sets all the crossover
frequencies and assigns EQ (as needed) to any combi­nation of NHT speakers!

If you have NHT speakers for some or all of your home
theater setup, your life just got a lot simpler. Answer Yes
to the Wizard's first question and away you go. If you
aren't using any NHT speakers in your speaker setup,
obviously answer No…you will be told to select the
speaker sizes/distances/levels manually. Instructions for
this immediately follow this Speaker Wizard section.

Run the Speaker Wizard again when you decide to
upgrade any speakers in your setup to NHT.

Here is the Back speaker menu progression and sec­ondary screens for each specific NHT product family for
the Speaker Wizard. After selecting one of the NHT
speaker family options on the left screen - Xd, Evolution,
Super Audio, Classic or Architectural, you will be pre­sented with the Back speaker screen asking if you have
1 or 2 back speakers.

You will be then be presented with the various model
choices within the product family you selected(except Xd
needs no further options). If you select Non-NHT
Speaker, you will be taken to the Subwoofer menu (re­turn and set the non-NHT Back speaker manually - later
in this chapter). If you select None, you will also be taken
to the Subwoofer speaker menu and any further
configuring for the Back speaker is unnecessary.

Here is the Subwoofer speaker menu progression and
secondary screens for each specific NHT product family
for the Speaker Wizard. Notice Xd is missing from this
list*! After selecting one of the NHT speaker family
options on the left screen - Evolution, Super Audio,
Classic or Architectural, you will be presented with the
various model choices within that product family. If you
select Architectural the Controller will need to know if you
have purchased it with or without an X1. Return and set
the non-NHT Subwoofer manually (later in this chapter).
If you select None, you will also be presented with the
Automated setup screen. No further configuring for the
Subwoofer is necessary.

* The Xd subwoofer should always and ONLY be con­nected to the XdAdigital integrated amplifier. Consult the
Xd manual for more information or just take our word for
it.

Congratulations, you're almost done with speaker setup.
If you selected Non-NHT speakers for any of your avail­able speakers, Exit to save your changes and proceed to
configure your Non-NHT speakers manually using
Speaker Setup from the Main menu. If you have all NHT
speakers, thanks and proceed to the Speaker setup
menu and run Auto Calibrate after that. Skip to the Auto
Calibrate section and get ready to enjoy your system.

Speaker Setup

Auto distance setup

To avoid difficult and not very precise manual calibration,
the Controller's speaker levels and distances can be
automatically set using the auto calibration feature (Auto
distance setup /Auto level setup). For this, you will need
the room to be quiet, as well as the included microphone
and cord provided with the Controller.

To auto calibrate the system, do the following:

1. Make sure a fresh battery is inserted into the micro­phone and connect it to the Controller front panel combo
headphone/microphone jack. Turn the microphone on
from its switch (small dot indicates "On" position).

2. Please connect the microphone to the combination
headphone/microphone jack ONLY when prompted by
the OSD.

3. Sit in your normal listening position and hold the
microphone in your hand or use a microphone stand of
some kind. Hold the microphone pointing straight up in
front of you.

4. With the cursor arrow on "Auto dist. setup" and press
the OK button.

The auto dist(ance) setup will run 3 tests per speaker
while measuring the distance. The screen shot here
shows the auto calibration has just completed 1 of 3 tests
on the Left main speaker. The next pass will show 2/3
and finally 3/3 and then move on to the next speaker until
completed.

When Auto distance setup is successfully completed,
readings in the Auto distance setup are changed. If not,
make sure calibration was successfully completed.

Auto distance setup works the same way as the Auto
level setup. Sound signals are sent to each speaker and
the response time is measured.

Note: If left and right speakers' distance (response time)
varies more than 2 ms, you will be notified. This variation
can often be balanced with right delay, but to reach opti­mal surround sound, consider moving your speakers into
a more symmetrical position.

19

Note: Auto calibrated distances may appear different
from measured ones. This is no error, because time for
sound to reach the listener varies depending on the room
and its atmospheric pressure.

Note: It is typical that the delay calibration for the sub­woofer shows higher values than you would expect (or
what your tape measurement actually shows). Auto cali­brate compensates not just for the physical distance
between speakers, but also for the "acoustical delay".
Typically, subwoofers have what is called "long group
delay" at lower frequencies. This is automatically com­pensated for when performing Auto distance setup.

Auto level setup

1. After Distance auto calibration is finished it will go

back to the Speaker setup submenu, move the cursor
arrow to "Auto level setup" and press OK button.

2. Auto level setup sends a test signal through all
speakers, measures their level with the microphone, and
increases volume to the right level. It starts from the left
speaker and continues clockwise to the other speakers.

3. When Auto level setup is done, turn the microphone
off and remove the battery from the microphone.

Note: Follow instructions on the OSD (highly recom­mended in Auto level setup!). If ambient noise from kids,
cars, air conditioning, people yippy-yapping, etc. is too
loud, the calibration will restart. Keep quiet and try to
eliminate external noises during setup, or reschedule for
late night when all is calm and quiet for best results!

Note: Once again, if satisfactory sound levels are not
reached in level calibration - if amplifier volume is too low,
for example - you will be informed on the OSD and front
panel display. Increase channel levels (see Speaker

setup / Manual level setup, page 21)

Note: If the Auto level setup is aborted, calibration level

changes will not be saved.

20

Manual distance setup

Note! If you use the Auto distance setup (highly recom­mended), you can skip the manual setup.

Sound coming from each speaker in the system takes a
certain time to reach the listener. The farther away the
speaker is, the longer the sound takes to reach your ear.
The Manual distance setup uses time delay as needed to
ensure sound from all the speakers reaches the listener
at the exact same time.

To make things easy, settings are displayed in feet or
meters and not in milliseconds (this option is set in the
Misc setup). As before, if some speaker is "missing" from
your system, it should say "None" on its line in the
Display setup submenu.

To set speaker distances manually, do the following:

1. Sit in your listening position and estimate or measure
the distance from your ears to each speaker.

2. Input the measured distances to each speaker using
the Left and Right arrow buttons.

3. To change unit from feet to meters or meters to feet, go
to the Display setup submenu (fourth item on the Main
menu).

4. Save setting by going to "Exit".

Manual level setup

Note! If you use Auto level setup (highly recommended),
you can skip this manual level setup.

The idea is to set all speakers in the system to the same
perceived or measured output level or volume at the lis­tening position. To achieve this, smaller or further away
set speakers must have their level increased and vice
versa. All the level settings indicated to the right of each
channel may have different numbers, or not…that's ok.
Again, speaker levels can be set manually or automati­cally with the Auto level setup function. To set manually,
select the Manual level setup and follow along:

1. Check to ensure that all your system's speakers are
shown on the OSD as set in the Size setup. If your sys­tem does not have a certain speaker, for example back
speakers or a subwoofer, it should read "None" after the
speaker's name.

2. Press the OK button on the remote control. Y ou should
now hear a short test signal circling around your speaker
setup (the active noise channel is indicated with a # on
the OSD). If not, make sure all speakers, and amplifier(s)
powering them, are turned on. The "Test" is turned off by
pressing the OK button again.

3. Listen or measure with a SPL meter to ensure that all
speakers have equal volume from the listening position.
When adjusting the level of a channel, the noise
sequencer stops on that channel. You can start the
sequencer again by pushing the OK button on the
remote. If not, use the remote's Left and Right arrow
buttons to go to the corresponding speaker's line and
adjust its level up or down and test levels again. Repeat
until you are satisfied that each speaker's level is the
same volume.

21

Manual size setup

Always start your speaker setup from the "Manual size
setup" sub menu because every other setting depends
on this information. The on screen display shows the
available speaker channels on the left side of the picture
and their respective size settings on the right of each.

If you select Large from this menu the Controller will
pass a full range signal (all audio frequencies present on
recordings) to only the speakers connected to that
channel.

If you select Medium, all frequencies below the Medium
crossover (Medium X-over) frequency will be sent to your
subwoofer.

If you select Small, all frequencies below the Small
crossover (Small X-over) frequency (just below in the
same submenu) will be sent to the subwoofer. This will
eliminate unwanted distortion in small speakers that do
not have the ability to properly playback lower
frequencies.

If you are not sure whether your speakers are "large",
"medium" or "small", consult an expert or try each of the
settings and listen which setting produces the best
sound.

Main speakers are the left and right front speakers of
your system. You can set them Small, Medium or Large.

The Center speaker can be set to Small, Medium or
Large or No. Setting it to "No" means that sound normal­ly sent to the center channel will be sent equally to the left
and right front speakers. The front two speakers will
create a "phantom" effect of the center speaker, assum­ing correct speaker and listener positions.

Surround speakers are located on the back or sides of a

5.1 system or at the sides of a 7.1 channel system (see
surround setup diagrams). Don't confuse these with
"back" speakers. Surround speakers can be set to
Small, Medium, Large or No. If you have no surround
speakers, you cannot have back speakers either. Sur­round first, back second or none at all.

Back speakers are either a single speaker in the middle
back of the room (mirroring the front three) used in so
called 6.1 channel systems or two equally spaced "back"
speakers in 7.1 systems. Dolby EX, DTS ES and of
course any 7.1 analog sources use the additional "back"
speakers. Back speakers can be set to none at all, 1
Small or 1 Large (6.1 systems), 2 Small, 2 Medium and 2
Large (for 7.1 systems). Back speaker signals are usual­ly "derived" from surround speaker signals. If you don't
have any back speakers, the Controller will direct any
signal meant for the back speakers to the surround
speakers.

22

The Subwoofer is the speaker playing the lowest fre­quencies in your system plus the low bass from any
speaker channel you may have set as "Small" and the
LFE signal (again, also called the subwoofer or .1 chan­nel). It can be set to Yes (you have one in your setup) or
No. If you select No, the Controller will direct the LFE
signal and bass from any other channel set to medium or
small to the front speaker channels if are set to Large.

The Subwoofer filter can be set On or Off. This is a low­pass filter (passes the lows - cuts the highs). Many
subwoofers have a built-in low pass filter, but it is best to
use the digital low-pass filter in the Controller; do not use
both at the same time. If you cannot turn the subwoofer’s
built-in filter off, turn it to as high a frequency setting as
possible.

Medium X-over allows you to select the frequency at
which you want to set the high and low pass filters (called
crossover point) for any speakers you set to medium in
the size setting. The filter value can be selected
between 20 Hz and 200 Hz in 5 Hz steps. Ideal setting
depends on your medium speaker's low frequency cut­off, room acoustics and/or personal preference. A little
experimenting with this setting will greatly improve your
overall frequency balance.

Small X-over allows you to select the frequency at which
you want to set the high and low pass filters for any
speakers you set to Small in the size setting. The filter
value can be selected between 20 Hz and 200 Hz in 5 Hz
steps. Ideal setting depends on your small speaker's low
frequency cutoff, room acoustics and/or personal prefer­ence. A little experimenting with this setting will greatly
improve your overall frequency balance.

Setup Example: Let's assume that you have the follow­ing setup:



very large or capable left and right main speakers

which can produce full bass (down to 30 Hz)



a center speaker which can produce some bass but

not as low as left and right (bass response to about
60Hz)



surround and back speakers that are small (bass
response to about 100Hz)

In this example, the following settings should be used:



Main = Large



Center = Medium (the medium x-over should be set
to 60)



Surround = Small (small x-over to 100Hz)



Back = small (small x-over to 100Hz)

We hate to harp but if you have NHT speakers this
process would be completely unnecessary and the set­tings would be made automatically in the speaker
Wizard!

Note: Save your settings by going to "Exit" and press the
"ok" button on the remote. Press Esc on the re-mote or
front panel to go back without saving your settings.

23

7.1 Channel in

An analog direct signal with up to 7.1 channels can be
connected to the "7.1 Channel in" connectors on
Controller's back panel. This is usually a DVD Audio or
Multi-channel SACD player or even a high quality stereo
source like a high-end phono pre-amplifier.

The 7.1 Ch in allows you to configure the 7.1 channel
analog inputs to best match your speaker setup for prop­er bass management. Your choices are All Small, L & R
Large or All Large.

The bass management for the 7.1 channel analog inputs
is done in the "analog" domain without any unnecessary
A-D (analog to digital) or D-A (digital to analog) conver­sions to preserve the audio quality even with SACD
sources. The crossover frequency is fixed at 80Hz.

Source setup

The "Source setup" consists of 10 preprogrammed mem­ory settings that assign a meaningful title like “DVD” or
“Game” to specific audio and video inputs along with any
sound profile Preset. This process is also called map­ping and allows simplified everyday operation of your
Controller.

The Controller has 10 programmable Sources. Sources
are not bound to specific audio video inputs - they can be
freely mixed. For example, if you have a DVD/CD-player
combo, you can connect it to one optical or HDMI input,
but have two Sources ("DVD" and "CD" for example)
deriving from that one input route, again to make opera­tion more intuitive.

In the Source setup menu, the first item, Source, selects
the Source to be edited. Use Left and Right arrows to
select.

Title of the Source can be changed to best describe the
content of the Source. Names can have up to seven
characters.

To rename a Source, go to the Title line and press OK in
the remote or scroll with the touch wheel on the front
panel. Adifferent view appears in which a small arrow (or
underlining in the display) indicates the character to be
changed. On the remote control, use Up and Down
arrows to select a letter, number or punctuation mark.
Use Left and Right arrows to move to the next character.
When renaming is completed, move the small arrow to
far right or far left and the OSD or display view is
restored.

24

Digital input selects one of the digital sound input sources
(HDMI, optical 1-3 or coaxial 1-3) to be used with the
Source.

Video In: selects the video input to be used with the
Source. Selections are Composite 1-6, S Video 1-4,
component 1-3, HDMI 1-3 and "Off".

Input monitor is used to adjust the gain of an analog
sound source and prevent the controller’s analog preamp
stage from clipping. Use the Input monitor after selecting
an analog sound source to be adjusted. When setting,
select an analog sound input playing something with a
loud signal, like an AC/DC recording, to adjust.

When adjusting the Input monitor, you should see lef t and
right channel level meters jumping up and down with the
sound volume. Set the input gain with Up and Down
arrows (remote) or by using the front panel touch wheel’s
up and down arrows. If volume is very low and indicators
stay very low, increase the gain setting. If you hear dis­tortion or "clipping" in the sound and indicators are raised
very high, decrease the gain setting.

To save settings in the Analog monitor, press OK in the
remote (or Menu button in the front panel). To exit with­out saving changes, press Esc in the remote (or any but­ton on the front panel).

Analog input: selects one of the analog input sources
(analog 1-6, Tuner or 7.1). If input is digital and not ana­log, the Analog monitor does not adjust input gain. In the
"Gain" line there is a text "Digital input".

Preset selects one of the five preprogrammed settings or
No change. They override global sound settings. Note: A
flat trim (i.e. no boost or cut or lipsync at all) or No change
(whatever was set is not altered including temp trims).
For more on Presets, see "Audio setup".

Audio setup

These settings control the audio of all sources and
modes if no overriding settings are made from other
menus.

The Audio setup menu lets you select Favorite mode
setup, Dolby/DTS setup, Preset setup as well as "gener­al" tone controls for treble, bass, LFE level, and Reverb.

Favorite mode setup

Favorite modes are shortcuts accesses from the remote
control’s 4 mode buttons: Direct, Movie, Music, Games.
You can assign different post processing modes (audio
processing features like Dolby Pro Logic IIx, and "non­processed" modes like Stereo and Mono) for Movie,
Music and Games. This can be done independently for 2
channel sources and multi-channel sources. The
Favorite mode setup is done once and then you can use
just "movie, music and games" buttons. If you want to
watch movies just press "Movie" etc. No need to remem­ber difficult post processing names like "Pro Logic IIx" or
"Neo:6"! The same shortcuts are also available on the
Controller’s front panel by pressing the first mode button.
Unit automatically knows if it is a 2ch (2 channel) or MCh
(multichannel) signal and will apply the correct post-pro­cessing mode. This makes every day operation much

25

easier to use than typical A/V receivers. The 6 choices
can be assigned to any or all of the 6 Source memories
or recalled by pressing the Mode key on the remote or
front panel. To assign modes, simply select one of the
favorite mode presets on the left and use arrow keys on
the touch wheel or remote to change preset to the
desired mode.

Dolby/DTS setup

These parameters are used with two-channel sources
like cd players or MP3 players that are listened to using
Dolby Pro Logic II Music or DTS Neo:6 modes. Both of
these modes turn any two-channel source, using the
Controller's digital or analog inputs, into "matrixed" multi­channel outputs, in which a multi-speaker, surround
effect is created from the (two speaker) stereo source.

PLII Panorama sends some of the main channel sound
to the surround speakers to create a wraparound effect.
Panorama can be switched on or off.

PLII Center Width blends the center channel output to the
left and right speakers. It creates a more spacious effect.
V alue can be set in eight positions (Min, 1-6 and Max). At
Max all center speaker sound is sent to left and right
channels. If you want more center channel separation,
use low values; if you want smooth blend between the
three front channels, use higher values.

PLII Dimension effect controls the front/rear balance of
the multi-channel audio. It can be set to values from -3 to

3. Zero value does not change the signal at all. Positive
values send more sound to the front speakers and
decrease spatial effect. Negative values send more
sound to surround speakers and increase spatial effect.

Neo:6 Center Image works like PLII Panorama: it sends
some front channel sound to surround speakers. The
effect can be set to six different positions (Min, 1-4 and
Max).

Preset setup

The Controller has five sound profile presets, which can
be assigned to individual sources in the Source setup.
Each profile preset can have its unique combination of
Treble, Bass, Center level, Surround level and
Subwoofer levels, plus a setting for Lipsync (delays the
audio output and allows you to adjust for better audio
and video sync) which is usually used with digital cable,
satellite receiver boxes and outboard video processors or
scalers.

When applied or assigned to a particular source, the
sound settings made using the Audio setup / Preset
setup override the sound settings made in the general
Audio setup. Apreset can be used to compensate the dif­ferent qualities and properties of different sound sources,
for example analog VCRs or even old phonographic
records.

Preset in the top line selects the preset (1-5) to be edit­ed. Treble, Bass, Center, Surround and Subwoofer levels
can be set from -12 dB (cut) to -12 dB (boost). Lipsync
can be set from Off to 150 ms (milliseconds) with 1 ms
intervals.

Treble and Bass: These levers control the boost of
Treble (high sound frequencies) and Bass (low sound fre­quencies). Bass and Treble boosts can be set from -12
dB to +12 dB.

LFE level: LFE or Low Frequency Effects are the lowest
noises, thumps and ka-booms, encoded to the digital sur­round signal. They are the ".1" in 5.1. LFE level control
sets their level between -10 dB and 0 dB.

26

NOTE: The LFE level is not the same thing as subwoofer
level. LFE is usually sent to the subwoofer, but if you
don't have one, the LFE is sent to the main speakers.

Reverb: Adds reverb, making your room potentially
sound like a different environment. Possible choices are
Dry 1, 2, 3 and wet. This affects the amount of reverber­ation or room size of the "Concert and "Club" music
modes.

Note: When applied or assigned to a particular source,
the sound settings made using the Preset setup over-ride
the "general" sound settings made in the Audio setup
menu.

Tuner setup

This menu allows you to setup the tuner presets, tuning
mode, TV system type and unit of measure for the speak­er setup menus.

There is a built in radio tuner in the Controller, which can
be used to listen to amplitude modulated (AM) or fre­quency modulated (FM) broadcasts.

Tuning Mode: Options are Auto(matic), Preset or
Manual.

Frequency: Displays the frequency selected for the
tuner preset.

Store to preset: Selects the tuner’s 20 presets, P1 ­P20. Press ‘OK’ on the remote to store.

Using the Am / FM tuner

The Controller's radio tuner can be used to listen to AM
(amplitude modulated) or FM (frequency modulated)
broadcasts. To listen, do the following:

1. Connect an antenna to the back panel of Controller.
Use right kind of antennas for both AM and/or FM broad­casts.

2. The Tuner is now selected by selecting the Source
where the tuner has been assigned. There is no Tuner
specific key on the remote.

3. Use band to select between AM and FM.

4. Use Tune + and - buttons to seek the wanted radio

channel.

5. Tuning can be set to automatic (auto seek) or manual
from the Tuner setup menu.

NOTE: automatic only works for FM.

27

Trigger setup

The Controller has two programmable (and 1 fixed) DC
trigger output jacks on the rear panel that are used to
control external devices. The triggers will send a DC sig­nal through the trigger output jacks and can be used to
turn power on and off from an amplifier, video display, or
motorized screen, for example.

Trigger sense sets the event that launches triggering.
There are several options, including power on/off of the
Controller, different kinds of inputs to the Controller and
activated Zone B.

Trigger polarity sets the mutual position of plus and
minus on the signal. See what works correctly on
receiving unit, or refer to the user’s manual of the device
to be triggered. Delay sets the time between trigger
activating event and triggering signal. Duration sets how
long a triggering signal is sent from Controller. Infinite
means that triggering signal stops only when the trigger
activating event stops. Other options are times; signal will
be sent at the chosen time in the beginning and end of
the trigger-activating event.

The third trigger is not programmable. It is active (on)
whenever the unit is NOT in the standby mode. Its polar­ity is positive and there is no turn on delay. The third trig­ger is optimal for power amplifiers used with Controller.

Note: If you are using the Controller with any NHT ampli­fiers with the NHTBus connected, you will not need to
connect the trigger cables to them as the trigger feature
is built into the system.

Misc Setup

TV System

This lets you change output format of the on screen dis­play to PAL or NTSC.

Warning: If you change this to a format your TV doesn’t
accept, the OSD will no longer work and you will only be
able to make changes via the front panel display.

Distance units

This lets you change the measured distance from feet to
meters.

Proximity mode
This lets you turn this feature on and off (see Proximity

Feature page 10). You may press any front panel button

or remote to get to the start screen.

Display

The front panel display has two settings, “always on” and
“auto off”. When set to “auto off” the display will go dark
after 10 seconds and can be turned back on by pressing
any remote control button or waving hand near the front
panel (when proximity mode is set to “on” - page 10).

Setup lock

This allows you to lock out the Controller’s setup mode
so no accidental setup changes can be made. To regain
access to the setup mode, press and hold the mute but­ton for five seconds when Setup lock dialog is shown on
the screen.

28

Reset all settings

If you should change your setup drastically because you
moved or added a number of new components to your
system or are unsure that you have set anything in the
menus right, you can start over. The Reset all settings
restores all the Controller’s setup parameters to the orig­inal factory default settings. This includes all speaker
settings, level and distant settings, trigger settings, TV
type, etc. In short, everything (except TV System set­tings, and source names)

The menu is simple to navigate. You will be asked on the
OSD if you are sure you want to reset the Controller.
Pressing the OK on the remote completes the process.
You will then be presented with a confirmation on the
OSD assuring you the task has been completed.

Care and Maintenance

You may need to dust or clean the Controller every once
in a while to maintain its beautiful finish.

WARNING: Make sure the power cable is
unplugged before cleaning.

Never use solvents, they will damage the surface. Only
use very soft cloth and very mild soapy water (1/2 ounce
of dish soap per gallon of water) on the top, sides and
front. Never clean the rear panel this way, this may dam­age the connectors. Simply dust the rear panel. Let the
Controller dry for an hour before returning it to operation.
