HTP-1 Release Notes, version 1.3
February 10, 2020
Welcome to version 1.3. 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.
The HTP-1 software team expects to continue updating this product for some time. The team expects to address the list of open issues.
523: Glitches in the audio stream from BlueTooth and Roon. This is most easily observed using a sine wave as a test source.
556: When no subwoofer is provided, the signal provided to the large speakers seem like a mono feed. This is because a bass redirection filter is not running. As a work around, declare a subwoofer and make all speakers small with the minimum 40Hz cutoff.
These issues are easily worked around:
558: On startup, the loaded Dirac filter may not be restored. This seems to happen at cold start, but we have had trouble duplicating it. When this happens, clicking Dirac on and off has no effect on the sound because no Dirac calibration is loaded. Go to the calibration page and select a Dirac calibration and everything will be fine.
564: Wides with no center not supported. Requesting this (8.1) will silently result in a 6.1 configuration without wide channels. There is no immediate plan to support wides with no center.
These features are not yet ready. The are to be enabled by software updates.
USB Audio (USB DAC function) not yet supported.
The secondary “downmix” output remains disabled in v1.3 pending a fix to mute transition noise.
Alexa Smart Home Skill has not yet been certified by Amazon so you cannot find it in the Alexa stores.
You cannot yet configure WiFi connectivity from the front panel: You must configure it through the wired Ethernet.
Roon compliance not complete.
WiFi causes dropouts on BlueTooth. Turn off WiFi to use BlueTooth.
Bluetooth audio can have (subtle) glitches. This is a software issue.
Some infrared remote keys (color, ABCD, 1234, BT Pair) are not implemented.
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:
Selects HDMI 2, Direct upmix mode, mute:
