selection, and various other system statuses. See the Front Panel LCD Display
section below for details.
2. Power Button: If the Master Power Switch on the rear panel is in the ON position,
the front panel Power Button turns the unit on or puts it into standby. While the
unit is booting, the button flashes blue. When fully powered on, the button
illuminates blue.
IMPORTANT! If you switch the unit off using the Master Power Switch on the rear
panel, wait at least 15 seconds before flipping the Master Power Switch to the ON
position, again.
3. Volume Knob: Rotate the Volume Knob counterclockwise to decrease the volume
level or clockwise to increase the volume level.
4. IR Receiver: The IR Receiver accepts infrared signals from the included IR Remote
Control.

Rear Panel
1. HDMI INPUTS: Eight HDMI® inputs for connecting HDMI source devices. Each input
supports the 4K resolution and the HDMI 2.0 and HDCP™ 2.3 standards.
2. ANALOG INPUTS: Two pairs of RCA analog stereo jacks for connecting up to two
analog stereo audio sources.
3. COAXIAL/OPTICAL DIGITAL INPUTS: Three digital coaxial and three digital optical
S/PDIF audio connectors for connecting digital audio inputs. All six inputs are active
and can be independently selected.
4. AES/EBU DIGITAL INPUT: Three-pin XLR jack for connecting an audio device that
outputs an AES/EBU (aka AES3) digital audio signal.
5. MIX OUT: One pair of RCA analog stereo jacks for connecting a stereo amplifier or
powered speakers. The input signal is mixed down to a stereo signal.
6. TRIGGER INPUT: This 3.5mm trigger input turns the HTP-1 on when a 12V signal is
applied. The HTP-1 will go into standby mode when the trigger signal is removed.
Note that the Master Power Switch on the rear panel must be in the ON position for
the trigger signal to turn the HTP-1 on.
7. TRIGGER OUTPUTS: These four 3.5mm jacks send a 12V 50mA trigger signal when the

BASIC SETUP
The best way to become familiar with the HTP-1 is to simply start using it! Before delving
into more advanced topics, we will connect one HDMI® source, an HDMI display, and a
power amplifier in stereo 2.0.0 mode. Perform the following steps connect these devices.
1. Place the HTP-1 in its desired location. Ensure that it is not in an enclosed cabinet,
that it has at least 3" of space around and above the unit, and that it is in a well-
ventilated area to ensure sufficient cooling airflow.
2. Ensure that all equipment to be connected is powered off and unplugged from its
power source.
3. Connect the included Bluetooth®/Wi-Fi® Antenna to the antenna jack on the rear
panel.
4. Using a Cat5e or Cat6 Ethernet cable (not included), plug one end into the
ETHERNET jack on the rear panel, then plug the other end into your Wi-Fi® router or
Ethernet switch. Note that the HTP-1 supports Gigabit (1000Mbps) data rates.
5. Using a Premium High Speed HDMI Cable (not included), plug one end into the
input on your HDMI® display, then plug the other end into HDMI OUTPUT 1 on the
rear panel.
Note that HDMI OUTPUT 1 supports the Audio Return Channel (ARC) and Enhanced
Audio Return Channel (eARC) HDMI features, which send audio from the connected
display back to the amplifier. The ARC/eARC feature is necessary if you plan on
streaming content from the internet using an application on your TV or if you plan
on receiving over-the-air TV broadcasts using an HD antenna connected to the TV.
6. Using an appropriate gauge of speaker wire (not included), connect your left and
right speakers to the left and right speaker outputs on your power amplifier. Ensure
that there are no stray wires and that polarity is properly maintained.
7. If your power amplifier has XLR inputs, plug a 3-pin XLR cable (not included) into
the left channel input on your power amplifier, then plug the other end into the
LEFT MAIN OUTPUT on the rear panel. If your power amplifier only has RCA inputs,
use an XLR to RCA cable (not included) instead. Repeat for the right channel.

18
8. Using a Premium High Speed HDMI® Cable (not included), plug one end into HDMI
INPUT 1 on the rear panel, then plug the other end into the HDMI output on a video
source device (e.g., DVD player, Blu-ray Disc™ player, satellite receiver, cable box,
etc.).
9. Ensure that the Master Power Switch on the rear panel is in the OFF position (Oside
depressed).
10. Plug the included AC Power Cord into the C14 Power Connector on the rear panel,
then plug the other end into a nearby AC power outlet.
11. Plug in and power on all connected devices. Start video playback on your video
source device.
12. Flip the Master Power Switch on the rear panel to the ON position (Iside
depressed) to boot the system. The Monolith™ logo will be shown on the LCD
Display and the Power Button on the front panel will flash blue while the HTP-1 is
booting up.
Once the unit has finished booting, the LCD Display will look similar to the display in
the PRODUCT OVERVIEW section and the Power Button on the front panel will
illuminate solid blue to indicate that the unit is fully powered on. For normal
operation, use the Power Button on the front panel or on the included remote
control to turn the unit on or put it into standby mode, rather than using the Master
Power Switch on the rear panel. The initial volume level shown on the LCD Display
should be -50dB.
Note that the HTP-1 has a Slow Start/Eco mode and a Fast Start mode. By default,
the unit is configured for Slow Start, which takes about a minute. The Slow Start
mode uses a lower power standby mode (below 500mW). You can configure the
HTP-1 for Fast Start on the SYSTEM tab on the System Configuration screen in the
Web GUI.
13. Slowly turn the Volume Knob on the front panel clockwise until the volume is at a
comfortable level. Verify that both the left and right audio channels are playing
audio properly and that there is video on your display.
14. Note the Wired IP Address in the bottom left corner of the LCD Display.

19
15. Open a web browser on your computer, then type http:// followed by the IP
Address on the display into the address bar and hit Enter to display the Web GUI
Home Page. Note that some browsers default to using https:// on the address,
which will not work. To be safe, it is best to explicitly type http:// before the
address. Create a bookmark in your browser, so you can quickly access the Web GUI
Home Page.
Note that the system has been tested and works well with the Chrome™, Firefox®,
and Safari® browsers, but has had some problems with Microsoft Edge®.
Congratulations! You have finished the Basic Setup and are ready to learn more
about the advanced features and functionality of the HTP-1.
SYSTEM CONFIGURATION
Click the gear icon in the upper right corner of the Web GUI Home Page to display the
System Configuration screen, as shown below. The specific functionalities and options on
each tab are described in following sections. The ?icon displays help information for the
current page.

SPEAKERS
About Speaker Configurations
A speaker configuration (also known as a Listening Mode) is described using 3 numbers
separated by dots and an optional letter suffix.
The first number is the number of speakers on the main listening level, with the speakers
arranged at the ear level of a seated listener. The second number is the number of
subwoofers in the system. The third is the number of speakers that are above the seated
listener, which are known as Upper or Height speakers. The hsuffix indicates that the
Upper speakers are arranged High on the walls, as opposed to in the ceiling, which are
known as Top speakers. Note that it is common to only use two digits rather than all three
(e.g., 5.1 rather than 5.1.0) when there are no height speakers.
For example, 5.1.4h indicates that there are 5 main level speakers, 1 subwoofer, and 4 High
speakers. A 7.1.4h configuration adds two additional Surround speakers at the back of the
listening area. A 9.1.4h configuration adds two additional Wide Surround speakers.
Speaker Location Diagrams
The following diagrams illustrate the ideal placement of the main level and upper level
speakers. Real world conditions may not allow for ideal placement, so this is just a guide to
the ideal. The upper level speakers should be mounted high on the wall or in the ceiling. All
speakers should be aimed toward the listener, if possible.
