Welcome
Congratulations on your purchase of the HTP-1 and welcome to software release version 1.7.1. Version 1.7.0 was a major update. Version 1.7.1 is a minor improvement on V1.7.0.
The HTP-1 is easily updated via its network connection and also easily reverted back to any previous releases so you are not stuck with an update that you don’t like.
This release note describes the state of the current software release.
The basic audio and video handling of the HTP-1 is quite stable. You should not expect crashes. You should be able to play any audio source that can arrive over HDMI. Control over a wired network is very stable. A detailed
user guide is available via the help buttons on the device as well as on the Monoprice web site. Goto the
HTP-1 product page and search for “User’s Manual”. The version of the user guide updated to match the current software release is accessed via the help menu on the HTP-1, or from this direct link: Monolith HTP-1 User Guide.pdf

HTP-1 Release Notes, version 1.7.1
August 13, 2020 Version 1.7.1 is created to clean up a few minor issues noted by early adopters of v1.7.0
New Features and Updates:
- Dirac filters from V1.5 and previous are now loaded and executed correctly.
- Exiting the Dirac Live program at various points does a better job of restoring the entire state.
- The Dirac button state now stays in sync with the processing even when loading a new filter.
- When a Dirac filter is active and you edit the user delay, the result is now accurate. Previously it was wrong until you reloaded the filter.
- The Tone Control now applies cleanly to all channels.
- A sine wave source is added to the signal generator.
- If the DNS server is not set, the update system uses a default and warns the user. This case previously blocked updating.
HTP-1 Release Notes, version 1.7.0
August 5, 2020
New Features and Updates:
- This version introduces support for Dirac Live Bass Control (DLBC). The Dirac handling code is extensively updated.
Users who have a Dirac license for DLBC can try it out. Without the updated Dirac license you should still be able to choose between the Dirac bass manager and the Monoprice bass manager.
- Dirac Bypass: The Dirac button now toggles between three states. On and Off work as expected. The new “bypass” state applies the delay and trim but not the filter. One of our power users has suggested arranging preset buttons with the preset recorder to switch directly between on and bypass.
- The signal generator page is active and described in the updated user guide. Choices include band limited pink noise and external inputs.
- Roon update: Roon now turns on and off correctly when navigating to or away from the Roon input. It also displays the signal processing chain.
- The “input sensitivity” control is renamed to “Maximum Output Level” and the user guide is updated to reflect this definition.
- The “Wide Synth” control button is moved from its association with DTS Neural-X to apply to all modes except “direct”. The user guide is updated to better describe its action. The level of the mix is reduced from -3dB to -6dB.
- The range of the tone control corner frequencies are increased.
- The user interface to “user trim” is updated to match the system’s half dB resolution. Previously you could adjust the UI by .1dB, but the system only changed at half dBs.
- Neural-X malfunction update: Using Neural-X, it was possible to get the system into a state of silent output with Neural-X and DTS-ES 6.1 tracks. This is corrected.
New Known Issues:
- Note that Dirac presets saved in HTP-1 using v1.7 will not be recognized and will be overwritten by v1.5 and earlier HTP-1 versions. Take care to ensure that your new Dirac work is saved in the Dirac Live tool before reverting.
Existing Issues:
- Play a truly mono movie (Casablanca) on a system with no center channel. Turn on Dolby Surround. There is no sound, as it is improperly beinh directed to the missing center speaker. This has always been the case.
- It has been noticed that the Chrome browser on Android phones can get in a state where the setup dialog box won’t close. Restarting the Chrome browser with the latest updates seems to resolve the issue.
HTP-1 Release Notes, version 1.5.1
May 7, 2020
This version contains a small number of updates to the video system. The audio system is unchanged.
- With the HTP-1 on and rendering audio from a source, disconnecting a TV or powering off some TVs would result in the loss of audio from the HTP-1 (assuming the source is still provided audio content). This behavior has been improved so there should only be a short loss of audio and then audio will continue to be rendered as long as the source continues to provide audio.
- There has been a minor adjustment to the eARC link startup message exchange which should improve eARC compatibility with some systems.
- The order of audio descriptors in the EDID has been changed to list the most preferred formats first. This also applies to the list of audio descriptors provided to a TV over eARC.
- The EDID block is adjusted so that PC sticks will boot while connected.
HTP-1 Release Notes, version 1.5
April 22, 2020
The changes in this version are:
- Updated kernel and drivers to prevent buffer underrun that causes audible artifacts when listening through Roon and Bluetooth.
HTP-1 Release Notes, version 1.4.3 HTP-1 Release Notes, version 1.4.2
April 7, 2020 Release version 1.4.3 rolls a collection of changes that have been tested in recent weeks.
Summary of changes in V1.4.3:
In addition to the changed described below in V1.4, this version is characterized by the significant changes:
- EQ page includes selection of shelf filters supporting the third party “BEQ” application.
- The network interface is enhanced to be friendly to a third party “macro recorder” that can be used to make presets.
- The EQ page includes a control to adjust the calibration of Loudness.
- The user guide is updated to describe the calibration of loudness.
- Improved muting to silence “pops” when changing inputs or stream status.
- Correctly restore volume with some DTS streams after muting.
- Ensure that 5.1 PCM streams remain identified as 5.1.
- Remove red (mute) color from volume display when volume is changed.
- Turn off wide synth in direct mode.
- Disabled false indication of wides in Dolby Surround so that “wide synth” can apply.
Known Issus in V1.4.3:
The HTP-1 software team expects to continue updating this product for some time. The team expects to address the list of open issues.
- #602: The Dirac Live tool does not reliably receive a description of the slots in use on the HTP-1.
- #523: Glitches remain in the audio stream from BlueTooth and Roon. A fix for this has been tested in house and rollout will begin soon.
- #598: Noises when changing volume with loudness on. Most notable when heavy bass content is played with much boost.
- #540: USB Audio (USB DAC function) not yet supported.
- #548: Roon compliance not complete.
- #518: WiFi causes dropouts on BlueTooth. Turn off WiFi to use BlueTooth.
- #538: Dirac Live may not find HTP if both WiFi and wired connections are active.
- Work continues on DTS-X Pro and Dirac Bass Control.
- Alexa Smart Home Skill has not yet been certified by Amazon so you cannot find it in the Alexa stores.
Earlier HTP-1 Release Notes
V1.4
March 10, 2020
The changes in this version were:
- Support up to 5 subwoofers. Note that Dirac v2.4.1 erroneously says it only supports one sub. Tests with the Dirac team show that this error message can be ignored. The User Guide is updated to give more information on managing multiple subs.
- The speaker configuration page now limits the number of speakers to 16 and reports when more speakers are attempted.
- The volume control responds more quickly.
- The limit of -30 is removed from the power on volume setting. Set it where you like.
- Bug 526 (no sub leads to mono L/R/C) is fixed.
- A power down button is added on the main page.
- The secondary output is enabled.
- A factory reset forces a browser reload.
- The “feedback” form is enhanced.
- Added more options for volume control. Both the volume buttons and the volume slider can now be enabled at the same time. There are also options to show 4 volume buttons with 1 dB and 4 dB step sizes.
- APM updated to v96 to solve a problem noticed on newer Auro disks.
- Corrected an issue in which the Dirac filter failed to load on startup.
- If a failure to fetch new updates has occurred, an nslookup to the server will be performed for diagnostic purposes.
- The User Guide reached form the help pages is updated to describe some of these changes. See the “Revision History”.
V1.3.2
February 24, 2020
- The maximum amplifier sensitivity is now limited to 4V to match the hardware capability.
- Clarify the use of the feedback form by suggesting contact with customer support:
- The ‘info’ icon on the Home page changes to yellow and a statement appears on the Detailed Status page if the development team has sent you a message in response to your feedback suggestions. However, please note that this channel is intended for the development team to clarify any of your improvement suggestions. It is not a replacement for the technical support channels provided above.
For the fastest technical support response please use one of the channels provided above.
The following bugs have been tested and found to have been fixed by the developers:
- 541: Static IP assignment not working. The procedure to select a static IP address was broken in v1.2. It is restored here.
- 557: Dirac trim sliders not consistent or remembered. When adjusting the channel trims in the Dirac Live tool, the trim settings were not remembered and applied for the calibration. This is corrected.
- 355: Limit precision of displayed Dirac trim. The UI is updated to show the correct amount of precision.
- 561: Subwoofer redirect level doesn’t scale with sub number. Now the redirected signal is scaled just like the LFE signal when the number of subs changes.
- 560: PEQ parser doesn’t accept decimal point frequency. In previous versions, specifying a non-integer frequency to PEQ would result in a bad filter setup.
- 463: Blasting volume slider. When the volume slider was selected it was possible to get the volume “stuck” at full volume. The volume slider is reworked and this no longer happens. (new volume config?)
- 553: Update the master volume when the amp sense is changed. In previous versions, changing the amplifier sensitivity did not immediately change the output volume. Now it does.
- DTS:X to DTS 192k transition: Playing a DTS:X stream and switching to a DTS-MA 192k stream with the sample rate converter engaged (Dirac or upmix) would not play correctly. Fixed.
- Do not turn off bass management on exiting Dirac early: Previously exiting the Dirac Live tool before completing the calibration would turn off the bass manager.
- User Guide updates. Download version 1.3 from the help page and see the Revision History for what has changed.
- IR remote code over HTTP support has been added. See below.
- The ‘Speaker Map’ link on the ‘System Configuration/SPEAKERS’ page links to a picture of the back panel overlaid with the speaker mappings. This shows the correct XLR connectors for the particular channels if they were enabled. If the speaker is not enabled, no sound will be produced.
IR Remote Code Feature:
The URL is
http://192.168.1.100/ircmd?code=XXXX where XXXX is the ‘NEC Code’ from the ‘IR Code Table’ in the User Guide. You should replace 192.168.1.100 with the actual IP address of your unit. More than one NEC Code may be sent by separating them with comma. Note that the code must be sent exactly as described in the User Guide: 4 hexidecimal digits, lower case, and without 0x prefix. The following example uses the ‘wget’ and the ‘curl’ command:
- Selects HDMI 1, Native upmix mode, unmute:
wget "http://192.168.1.100/ircmd?code=0ff0,1ee1,4cb3"
curl "http://192.168.1.100/ircmd?code=0ff0,1ee1,4cb3"
- Selects HDMI 2, Direct upmix mode, mute:
wget "http://192.168.1.100/ircmd?code=10ef,4bb4,1be4"
curl "http://192.168.1.100/ircmd?code=10ef,4bb4,1be4"
