Requirements
A laptop or desktop personal computer, along with a calibrated microphone (not included), are required
to perform a Dirac calibration of the HTP-1. A smartphone cannot be used to perform a Dirac calibration.
Other advanced features can be configured via a personal computer, tablet or smartphone using a web
browser.
The HTP-1 must be connected to a home network, either wired or wireless. The computers, tablets and
smartphones that are used to control the HTP-1 must be on the same network as the HTP-1.
A separate amplifier or powered speakers are required. The outputs of the HTP-1 must be amplified in
order to drive speakers.
Basic Setup
The best way to become familiar with the HTP-1 is to start using it. Let’s start simple. For this exercise,
you will connect one HDMI source, a TV, your amplifier and get some sound to come out. Follow the
steps below to get you started.
Step 1 : HTP-1 Network Connection
You will be using a personal computer, tablet or smartphone to setup the HTP-1. The initial setup will be
easier using a device with a larger screen such as a tablet or laptop.
The HTP-1 supports both wireless and wired ethernet. For the initial setup it is recommended that you
use a wired ethernet connection to the HTP-1. That will help to avoid some possible initial complications
with WiFi.
Bluetooth and wireless ethernet use the same antenna on the back of the unit. This is a good time to
check that the wireless antenna is attached to the back of the unit.
Connect your ethernet router or switch to the ethernet port on the back of the unit. The ethernet port
on the HTP-1 supports Gigabit (1000Mbps) data rates. If you prefer to have the HTP-1 connect to your
home network over WiFi then follow the WiFi set up instructions later in this document.
Step 2 : Amplifier
Connect the output of the HTP-1 to your amplifier(s). You can start off by simply connecting the
amplifier to the ‘LEFT’ and ‘RIGHT’ (front left and front right channels) XLR outputs on the back of the
HTP-1. For information on connecting the rest of the channels refer to the “Advanced Setup Topics,
Page 7

HTP-1 Installation and User Guide Version 0.5
Speaker Setup” section. For the best audio performance, the HTP-1 should be paired with an amplifier
that has balanced inputs. An adapter cable can be used to connect to an amplifier with unbalanced
(RCA) inputs with some loss of dynamic range. The adapter cable should leave the extra, unused signal
output disconnected.
Step 3 : HDMI Source and TV
Connect a reliable HDMI source (cable box, Blu-ray player, AppleTV, etc). Plug the HDMI source into the
HDMI Input 1 port.
Tip: using a Blu-ray setup disk with channel ID tracks will be quite helpful for troubleshooting and
verifying the speaker setup.
Connect the primary television to the HDMI 1 output port. Only the HDMI output that is labeled, “ARC /
eARC” is ARC / eARC-enabled; HDMI output 2 does not support it. ARC / eARC allows a digital audio
signal to be sent from the TV to the HTP-1. This is essential if you plan on streaming video from the
internet by using an application that runs on the television or if you plan on receiving over-the-air
television broadcasts via an HD antenna that is connected to the television. Both HDMI outputs have the
same video resolution capabilities.
Step 4 : Power on the Unit
Connect the provided power cable to the 120V/240V wall socket. Flip the switch on the back of the unit
to the ON position; this will cause the unit to boot up. The HTP-1 has a slow boot/ eco mode and a fast
boot mode. By default, the unit is set for slow boot, which takes a minute. Slow boot mode uses a lower
power standby mode; below 500mW. Once the unit has finished booting the LCD will look as described
in the following section. The unit can be setup for fast boot on the “System” tab in the web server. The
power button on the front of the unit should be used to power on and off the unit during normal usage.

HTP-1 Installation and User Guide Version 0.5
Step 5 : Get to Know the Front Panel
The LCD front panel provides a summary of the critical HTP-1 settings. Currently, the LCD touch screen interface is
only used for WiFi setup and to mute the unit. See the WiFi setup section for more details. The user controls the
HTP-1 with the remote control and through the web interface via a tablet, PC, laptop or smartphone.
1. The current input is displayed in the upper left corner. Here it says “HDMI 1." This text is configured on the Input
Setup Tab detailed later in this document.
2. This section describes the format of the source. In this example, the “Program Format” is Dolby Digital 5.1.0. An
appropriate icon is displayed. The “channel” format of the stream is described with three numbers and sometimes
with a modifying letter. This is described in more detail in the subsequent section “About Speaker Layouts."
3. The volume is prominently displayed in the center of the screen. The “dB” value is relative to the amplifier input
sensitivity setting that is configured on the “System Configuration” setup tab. When the system is muted the volume
is displayed in red. The system can be muted by tapping the volume display area on the front panel, by pressing the
mute button on the remote, or by clicking on the volume display area on the web page.
4. This is the current upmix setting. The upmix or “surround mode” is selected via the web page interface or the remote
control. The selected mode only reflects the desired/requested upmix mode. The system will perform the requested
upmix only if is supported. The listening format (number 8 in the illustration) displays which upmix mode algorithm is
being utilized, which may not always match the requested mode. This is discussed in more depth in the subsequent
section on “Using Surround Modes.”
5. This is the current setting of the special listening modes. In this illustration, the Dirac room correction filter is
disabled, night mode is off, loudness is off and dialog enhancement is off.
6. This is the current IP address of the HTP-1. To configure/control the HTP-1, navigate to this address using a web
browser on a PC, tablet or smartphone. It may be necessary to enter “http://” before the IP address. For this example,
the IP address of the unit is 192.168.97.126. The user would therefore enter either 192.168.97.126 or
http://192.168.97.126 into the navigation window of the browser. Some browsers default to https. This will not work.
7. Touching the blue “gear” in the upper right corner brings up a display designed to help you connect the HTP-1 to your
home WiFi network. Refer to the WiFi setup section later in this document. If the gear is yellow that means that there
is an update available for the unit.
8. The right hand describes the format of the presentation. In this example, the “Listening Format” is configured for a
“2.0.0” channel arrangement. An appropriate icon is displayed. No icon is displayed for “Direct” presentation.
9. When the HTP-1 is connected to a wireless network the IP address will be displayed in the lower right hand corner of
the front panel. The HTP-1 will favor the wired connection if available.
Page 9

HTP-1 Installation and User Guide Version 0.5
Step 6 : Connect to the HTP-1 Web Server
If you connected the HTP-1 to your home network via a wired ethernet connection, after booting up the
HTP-1, it will have acquired a local IP address, which will be displayed on the front panel of the unit, in
the lower left hand corner.
Open a web browser on a tablet, laptop or PC that is connected to the same network as the HTP-1. In
the web browser type the IP address that is displayed on the LCD panel of the HTP-1:
http://xxx.xxx.x.x
Note: do not use “https.”
Some browsers use http by default. If this is the case then you can simply type the IP address and not
“http://.”
Create a bookmark on your browser so that you can quickly access the unit.
The homepage of the HTP-1 should open up and look something like this:
Page 10

HTP-1 Installation and User Guide Version 0.5
Step 7 : Get to Know the Homepage
The homepage is the primary control and configuration interface for the HTP-1.
1. The current active input is displayed in the upper left corner. Here it says “Sony DTS." This text is configured on the
Input Setup Tab detailed later in this document. Clicking on the active input in the upper left corner brings up a quick
select to choose any input. Click on it and choose HDMI 1. If you have connected an HDMI source to input 1, and the
source and TV are powered on, you should see video displayed on the television at this point.
2. The left hand side describes the format of the source. In this example, the “Program Format” is “5.1.0 DTS MA.” An
appropriate icon is displayed. The “channel” format of the stream is described with three numbers and sometimes
with a modifying letter. This is described in more detail in the subsequent section “About Speaker Layouts."
3. The volume is displayed in the center of the screen. The “dB” value is relative to the amplifier input sensitivity setting
that is configured on the “System Configuration” setup tab. When the system is muted the volume is displayed in red.
The system can be muted by tapping the volume display area.
4. This is the volume slider. There is an option in the “System” tab to select either a slider or buttons for volume control.
5. This is the quick “Input Select” area. Up to 8 inputs can be configured to display in this area. Clicking on these buttons
changes inputs. The inputs can also be named. Which inputs are displayed and how they are named are configured on
the “Inputs” tab described later in this document.
6. The upmix or “surround mode” is selected here or via the remote control. The selected mode only reflects the
desired/requested upmix mode. The system will perform the requested upmix only if is supported. The listening
format (number 8 in the illustration) displays which upmix mode algorithm is being utilized, which may not always
match the requested mode. This is discussed in more depth in the subsequent section on “Using Surround Modes.”
7. This is the current setting of the special listening modes. In this illustration, the Dirac room correction filter is enabled,
night mode is off, loudness is off and dialog enhancement is off. The Dirac button is disabled unless a Dirac
calibration has been performed.
8. The blue Gear button provides access to the setup tabs - “Speakers, Calibration, EQ, Inputs, Sound Enhancement,
Connectivity and System.”
9. Clicking on the blue Information button will bring up detailed status as well as access to in-field updates and the
ability to roll-back the current software installation. If the button is yellow that means that there is an update
available for the unit.
10. This is the Help button. Each section of the web interface (homepage or configuration tabs) will have a help button
that provides useful information about the current tab or page. The user guide is also accessible via the Help button.
Page 11

HTP-1 Installation and User Guide Version 0.5
11. The top-right text describes the format of the presentation. The “Listening Format” is configured for a “5.1.4
AuroMatic” channel arrangement. An appropriate icon is displayed.
7a : Input Selection Alternative
Clicking on the active input in the upper left corner brings up the input selection buttons, which lists all
possible inputs. The custom names of the inputs are not displayed here.
7b : System Configuration Tabs
Clicking on the blue Gear button brings up the “System Configuration” tabs, shown below. Details about
each tab are addressed further down in this document.
Step 8 : Listen to Audio
At this point, if the HDMI source device is playing, the amplifier is on, the volume is up, the HTP-1 is
configured for the correct input, and the TV is set to the input that the HTP-1 is connected to, you
should then be able to hear audio. If not, check the setup. Revisit the previous sections.

Advanced Setup Topics
If you followed the Basic Connections instructions above you should be ready to use some of the more
advanced features.
About Speaker Configurations
A speaker configuration (also called a listening mode) is described by three numbers and an optional
letter. The first field is the number of speakers in the main listening level. These speakers would be
arranged at the ear level of a seated listener. The second field describes the number of subwoofers. The
third field describes the speakers above the listener. These are referred to as height speakers. For
example, 5.1.4h indicates that there are 5 main level speakers (front left, front right, center, and left and
right side surround) with 1 subwoofer, and 4 height (Atmos) speakers. The ‘h’ indicates that the height
speakers are mounted high on the wall, as opposed to on the ceiling. A 7.1.4h system would add two
additional surround speakers at the back of the listening area. A 9.1.4h system would have two
additional “wide” surround sound speakers. See the following sections for examples of various speaker
configurations.
It’s common to describe speaker configurations with no upper speakers using only two fields. For
example, 5.1 is the same as 5.1.0.
The speaker configuration tab, which is accessed by clicking on the blue Gear symbol on the homepage,
is a great reference for understanding various speaker layouts.
Page 14

HTP-1 Installation and User Guide Version 0.5
Speaker Location Diagrams
These two diagrams illustrate the ideal placement of main level and upper level speakers. Real world
rooms may not allow for ideal placement. This is just a guide. Do the best you can. The main level
speakers should be placed at the ear level of the listener. The upper level speakers should be mounted
high on the wall or on the ceiling. All speakers should be aimed in the direction of the listener.
Page 15

HTP-1 Installation and User Guide Version 0.5
Valid Speaker Configurations
The HTP-1 can support up to 16 output channels. There can be up to 9 main level channels, 6
upper/height channels, and up to 3 subwoofers. These can be allocated in various ways. Some of the
more complex ways are discussed in the following sections.
The speakers in the main and upper levels are restricted to the following configurations:
Main Level Speaker Count/Configuration
Upper Level Options*
2 Speakers: L/R Front
0 or 2 Speakers
3 Speakers: L/R Front + Center
0 or 2 Speakers
4 Speakers: L/R Front +L/R Surround
0, 2, or 4 Speakers
5 Speakers: L/R Front + Center + L/R
Surround
0, 2, 4, or 6 Speakers
6 Speakers: L/R Front + L/R Surround + L/R
Rear
0, 2, 4, or 6 Speakers
7 Speakers: L/R Front + Center + L/R
Surround + L/R Rear/Back
0, 2, 4, or 6 Speakers
8 Speakers: Not Supported
0, 2, 4, or 6 Speakers
9 Speakers: L/R Front + Center + L/R
Surround + L/R Rear + L/R Wide
0, 2, 4, or 6 Speakers
*Refer to the table below regarding upper level options.
Page 16

HTP-1 Installation and User Guide Version 0.5
The HTP-1 can support many different configurations of upper speakers. The upper speakers can be
“high,” which are mounted on the wall, or “top,” which are on the ceiling firing down. “Dolby Enabled”
speakers are also supported. Dolby Enabled speakers act like top speakers by bouncing the sound off of
the ceiling. Dolby Enabled speakers are convenient in that they are integrated with typical front firing
(front left and right) speakers. They work well when the ceiling is flat and reflective to sound.
Dolby content is typically authored with upper level speakers on the ceiling. DTS and Auro-3D content
are typically authored with speakers high on the wall. The HTP-1 system “remaps” the source material to
match the user-defined speaker configuration. The upper speakers are configured as follows:
Upper Level Speaker
Count/Configuration
Details, Suggestions, and Restrictions
2 Top: middle or top front
pair only
Dolby content is often authored assuming only the top middle
speaker pair. If only two upper speakers are available, top
middle is the best bet.
2 High: front pair only
If your speakers are here, then use this setting. But this is not
a preferred speaker arrangement.
4 Top: 4 ceiling mounted
(down firing speakers,
front and rear left and
right)
A Dolby-preferred speaker layout. Other formats also support
this.
4 High: 4 wall mounted
high speakers, front and
rear, left and right
The DTS-preferred configuration.
4 Mixed: front high, rear
top or front top and rear
high
If your speakers are most easily set in such a mixed
arrangement, HTP 1 can be configured to map the signal to
these configurations.
6 Top: front, middle and
rear
Best of both worlds.
6 High: front and rear are
high on the wall
The signal for the upper middle pair is actually the “top
middle." The Auro-3D “Voice of God” signal is routed to the
top middle pair.
6 Mixed: top middle plus
front high, rear top or
front top and rear high
Not an ideal layout, but use it if this matches your system
best.
Note: All top speakers can be “Dolby Enabled.”
Page 17

HTP-1 Installation and User Guide Version 0.5
The status display will differentiate between “top” and “high” by appending an “h” when the uppers are
high. The modifiers “/” and “\” are used to indicate the mixed configurations. “Top” is higher than “high”
so “/” implies top in the rear and high in front.
The setup allows many choices so you can configure the decoders to drive the speakers that you have.
But a few configurations are preferred:
- The HTP-1 supports up to 3 subwoofers depending on main and upper level channel allocation.
- 5.1.2 is a “minimum object audio” recommendation.
- 7.1.4 is a “normal object audio” configuration.
- Six upper speakers gives a clear advantage to match common source material exactly without
remapping.
- More than one subwoofer can minimize dead spots in the low frequency material.
Mapping Channels to Speakers
There can be cases in which the channels found in the program material do not exactly match the
speakers in the room. The various decoders apply “remap” algorithms to pan the source signal to the
best available set of speakers. This is best illustrated with a set of examples:
1) DTS material is typically constructed with “high” channels, but a room may have only “top”
speakers. DTS applies a “remapping” feature in this case and the resulting signal is heard both
from the top speaker as well as from the matching main level speaker. The sound from the front
left high speaker is hence panned between the top left high and the top left speaker so that it
sounds like it is coming from the high speaker location between these two.
2) A 5.1 DTS stream is usually authored with the surround speakers at 110 degrees from the
listening position (see the Speaker Location Diagrams on previous page). A 7.1 speaker setup
places surrounds (sides) at 90 degrees and rear speakers at 135 degrees. Hence a 5.1 DTS signal
is typically presented with the surround signal split between the side and rear speakers.
3) The full Auro-3D channel set includes the “Voice of God” (VoG) speaker located directly
overhead and the “Front Center High” or “Center Vertical High” (CVH) speaker on the wall above
the screen. These signals are not directly supported as they are not generated by the other
decoders. Like all of the higher speaker modes, the available signals are mapped to the available
speakers. The VoG signal is routed equally to the two “top middle” speakers, if available. In a
“.4” configuration, the VoG signal will be routed to all 4 upper speakers. The CVH signal is split
between the upper front signals.
4) The Auro-3D speaker set is in fact “high” channels, not top channels. If you choose to install top
speakers, the Auro-3D high channels are mapped directly to the top speakers.
Dolby Atmos and DTS-X are object audio systems. This means that sound “objects” do not have to be
located in a fixed channel but instead are decoded to match the available set of speakers. This makes it
possible to move sounds around a room reliably with various speaker configurations. Auro-3D on the
other hand is a channel-based system. The fixed speaker locations need to be rendered to the available
speakers. This is also apparent when a stream is constructed with a mix of channels and objects.

HTP-1 Installation and User Guide Version 0.5
Speaker Setup
Click on theGear icon in the lower left of the homepage to access speaker setup. Then choose the
“Speakers” tab. The HTP speaker configuration is set by clicking on the toggle switches in the left-most
column. Blue indicates that the speaker is enabled. When you have enabled a speaker, or set of
speakers, they will appear in the illustration on the right hand side of the pane, which will help you place
the speakers in the correct position in the room. In the graphic, squares represent subwoofers and
circles represent height/upper speakers.
The speaker setup page guides you to enable speakers in supported configurations. This is discussed
below.
The “Small” button in the second column enables a high pass filter with a user-selectable corner
frequency. Blue indicates which option is chosen--“Large” or “Small” or “Dolby.” The following sections
contain some examples of speaker configurations.
Setting Speaker Size
Most speaker setups will use small speakers. If you are not sure if the speakers are small or large then
they are probably small. A large, full-range speaker does not need a subwoofer to produce the lowest
frequencies. Selecting the “Small” toggle switch means that the lowest frequencies are redirected to the
subwoofer. This protects the small speaker and allows it to operate more efficiently. Many speaker
manufacturers will provide the frequency response of their speakers. For example “60Hz to 18KHz”
indicates that the speaker is not designed to produce sounds below 60Hz, or so. In this case you would
want to set the corner frequency of the high pass filter to 60Hz or maybe 10Hz above the cutoff.
Choosing a cutoff that is clearly in the linear region of the speaker ensures that the crossover operates
as designed and is not affected by the natural filtering of the speaker. The HTP-1 uses a fourth-order
Linkwitz-Riley crossover.
The settings of the speaker sizes do not affect the Dirac calibration. The bass manager runs before the
Dirac filter. The Dirac calibration ensures that the signal sent to the speakers is reproduced as intended.
After doing the Dirac calibration you can see the cutoff frequencies measured on your speakers and
then complete the configuration of the “Speakers” page by filling the corner frequency for each pair of
speakers. Ideally the corner frequency chosen on the speaker setup page is 5 or 10 hertz above the
frequency at which the speaker begins to roll off. That way you use the fourth-order Linkwitz-Riley
electronic crossover provided by the HTP-1 and don’t rely on the less predictable behavior of the
speakers.
A Dolby Enabled speaker behaves like a “small” speaker except when a Dirac calibration is performed.
The calibration preserves the special filters used in Dolby Enabled speakers.
Page 19

HTP-1 Installation and User Guide Version 0.5
Enabling Speakers
When you first open the speakers configuration pane only the front left and right speakers are enabled.
The sliders will not allow you to select an unsupported speaker configuration. Refer to the tables above
for supported speaker configurations. HTP-1 follows rules set by the Dolby and DTS decoders. Some of
the rules are:
- The L/R rear surround speakers cannot be enabled until the L/R surround speakers are enabled.
- The L/R wide speakers cannot be enabled until the L/R rear surround speakers are enabled.
- Subwoofer 3 cannot be enabled until subwoofer 2 is enabled.
- There is no “side middle high" configuration. You must first choose top front speakers to select
the top middle.
- You cannot have only rear upper speakers. The first pair must be front or middle.
- There is no “high” middle speaker. If you want to have six upper speakers they must be
configured as “top."
If you have only two upper speakers it is a good idea to choose the top middle pair. Many Dolby tracks
are authored to favor this upper pair. The “5.1.2” Atmos configuration uses the top-middle pair. DTS-X
streams are likely authored using four high speakers. The HTP-1 carefully “remaps” any source
arrangement to match the speaker setup you choose. This is why you should describe/configure your
speaker setup as accurately as possible, though few people will be able to tell the difference if a pair of
speakers labeled “top front” are actually high on the wall in front.
Dolby Enabled Speakers
Dolby Enabled Speakers have two independent drivers with two independent inputs. One of them points
up so that the sound will reflect off the ceiling and appear to be a speaker on top. A Dolby Enabled
speaker must also include a filter to enhance the illusion of the sound coming from above.
