Firmware and Version History
Latest Version: 1.1.1 (1/13/2019)
Release Notes:
Spoiler!



Issue Tracker
A list of known open issues with the HTP-1 will be tracked here. Only issues confirmed by multiple users or issues acknowledged by Monoprice will be listed.

#Summary of IssueSteps to ReproduceReproduced by UsersReproduced by Monoprice
4One or more subwoofers are sometimes lost and do not receive any signal when they should. Restarting the HTP-1 fixes the issue (changing Dirac slots back and forth does not).To reproduce, open Dirac and connecting to the HTP-1 while no calibration mic is connected to the computer, dismiss the error and close Dirac. This will result in the HTP-1 bass manager being disabled. To fix it, reboot the HTP-1 after closing Dirac Live.@pink soda, @tyson1749 Yes
6Audio dropouts or static can occur in rare situations with default settingsThere are a few different situations where users have reported this. One is, when the audio of a movie goes completely silent, the HTP-1 briefly loses signal before it comes back, which can cause the first few seconds to be cut off when the audio returns. Another occurred for one user when playing 4K blu-rays with Atmos tracks, where the audio worked for the main menu of the blu-ray, but played static when actually starting the movie. Both of these issues can be worked around by enabling Advanced Input Settings on the System tab and then setting PCM Detect Sensitivity to Indicated for any inputs which have the issues.@pink soda, @ronin22, @matty1137 Yes
7In Dirac software, channel sliders have no effectStart a new Dirac calibration, try adjusting channel sliders within Dirac software. Dirac will preview the adjusted channel level, but if you test it by playing pink noise, the actual level does not match the previewed level because the channel sliders have no effect.@pink soda, @ronin22Yes
8Setting static IP in the HTP-1 does not workWhen choosing a static IP in the HTP-1 config, it does not get that IP address after rebooting the router. Workaround: reserve a static IP for the HTP-1's MAC address in router settings.@pink soda, @wilbur_the_gooseNo
Here is an archive of issues that have been fixed and which version they were fixed in:

FAQs and Tips
Requirements for Dirac Live Calibration
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.

Currently, Dirac calibration requires a PC or Mac Laptop running Dirac Live with an external mic attached to the laptop. Dirac recommends using the MiniDSP UMIK-1.

Tips for Ensuring a Successful Dirac Calibration
Quick Start Guide from Dirac: https://live.dirac.com/content/uploa...nt-version.pdf

While Dirac is generally not too sensitive to small differences between calibrations, it is very important to make sure all of Dirac's calibration guidelines are followed as closely as possible to get the best result. Here's a summary of those I feel are most important to ensure a proper calibration:
  • Take the first measurement in the desired sweet spot position, which should be equidistant to and exactly between the front left and front right speakers, even if there is no seat exactly between these two speakers. After performing the calibration, this can be verified by checking the Dirac Calibration Delay (ms) values for the front left and front right speakers in the Calibration tab of the HTP-1 configuration, which should be equal to or very close to each other.
  • For the first measurement only, the mic should be at ear height when sitting down in the main seat. For the UMIK-1, the mic should be pointing straight up, the tip of the mic should be at ear level, and the 90 degree calibration file should be used.
  • While taking a single measurement for the Dirac calibration can be useful for testing purposes, it will not give Dirac enough information to produce a calibration result that sounds good (it may sound dry and dull). The more data Dirac is given, the better the results end up being.
  • All measurement types involve mic positions at three different heights -- ear level, above ear level, and below ear level. All above ear level positions and below ear level positions should be several inches above or below the ear level position. For example, my ear height when sitting down at the main seat is 41 inches. So when doing a couch calibration, I take the first measurement in the sweet spot with the mic tip 41 inches high, the next 8 measurements with the mic tip at around 49 inches high, and the remaining 8 measurements with the mic tip around 33 inches high. While it's not necessary to be this precise with mic heights besides the first position, it helps me to have a quick and simple process to follow with every calibration.
  • No two mic positions should be too close to each other (specifically, Dirac recommends a distance of 40-60cm between measurement points), and no mic positions should be reused to take multiple measurements in the same position.
  • No mic positions should be too close to any reflective boundary (~1ft) if possible. If seat backs are very close to any mic position, it can help to fully recline all seats while performing the calibration. This made a big difference on my particular setup and I always recline my seats when performing Dirac calibrations now.
  • For every mic position, the mic tip should have an unobstructed line of sight to every speaker (besides subwoofers) if possible. Reclining my seats helped me achieve this with some of my rear speakers.
Additional comments from @AustinJerry :
  • First, it is extremely important to establish the proper levels for all speakers, including the sub channel, at the beginning of the Dirac calibration. The final speaker output levels are closely influenced by which speaker has the lowest level at the beginning of the calibration. If any speaker, or speaker group, has a level that is too low, all final output levels will be low, requiring a higher master volume setting to reach normal listening levels, which can be frustrating.
  • Finally, while it is essential that enough measuring points be used, and that as long as the guidelines mentioned above are followed, I have found that Dirac results are highly repeatable. I remember from my days in the Audyssey support threads, users would be obsessed with experimenting with different mic measurement patterns, claiming that the “magic” placement would result in significantly better results. I have not found this to be the case. Over the many calibrations I have performed following good practices, the results have always been consistent, and consistently good, measured by REW and by my listening tests.

List of Suitable XLR to RCA Cables/Adapters
Note that this list is for connecting XLR to RCA, which is only required when connecting to amplifiers that do not have XLR inputs. For amps that do, any XLR male to female connectors will work.

List of adapters/cables will be added as they are tested and confirmed to work.

Troubleshooting any issues with the HTP-1
If the HTP-1 is having any sort of issues at all, see if any of the following resolve the issue:
  1. Change input and change back. This usually resolves issues if a source is playing static noise.
  2. Power cycle, with Fast Boot mode enabled. This resets the DSP and can resolve issues related to the DSP.
  3. Power cycle, by flipping the power switch on the back of the unit and leaving it off for a minute. This can resolve issues such as Dirac not being able to find the HTP-1 on the network.

Is there away to use PRO level microphones like earthworks M30?

Any USB microphone can work. A small capsule calibrated omnidirectional mic is preferred.

To utilize an XLR mic like an Earthworks you must connect a USB interface/preamp. Most common are the Focusrite Scarlett series (I use Roland Quad/Octa Capture).

The UMIK-1 mic sold by miniDSP comes with calibration file down to 10Hz and up to 20000KHz. The one calibrated and sold by CSL goes down to 5Hz (mine down to 4.33Hz actually) and up to 25000KHz. The big advantage of the UMIK-1 mic sold and calibrated by CSL is that each calibration (0 degrees, 45 degrees and 90 degrees) is actually taken. However, the UMIK-1 sold by miniDSP is calibrated only Standard (0 degrees) and the 90 degrees data is extrapolated or "automatically generated" from the 0 degrees calibration data.

Can you explain why the UMIK is not capable of measuring SPL? I used to use my Radio Shack Analog SPL meter to equalize my channels with pink noise and map my frequency response.

I think you are miss reading Marc's recommendation as the UMIK-1 is more than capable of measuring SPLs. In fact, it's the one I use for serious SPL reading and gain match my subwoofers. I think what Marc is saying is that for $14.50 you can have a very good mic for SPL reading if you don't have a UMIK-1 already or want something more compact so you don't need to take your laptop, USB cable and UMIK-1 mic out. Just plug the Dayton IMM-6 into your iOS or Android device and you are done

I'm 99% sure the miniDSP and Dayton provided calibrations are only down to 20Hz.

Just double checked two of my UMIK-1 calibration files from miniDSP and they do go down to 10hz. Can't speak for the Dayton.

Excellent!

My UMIK-1 is from CSL. I'll compare it to the miniDSP CAL file. Purchasing from CSL is preferred but probably unnecessary (CSL has a history of going out of stock for long periods… perhaps they have resolved this?). Absolutely precision is not necessary for REQ in the bass region.

I just noticed that PE stocks the UMIK-1 now. PE is always offering promotional discounts and free shipping.

I just noticed that PE stocks the UMIK-1 now. PE is always offering promotional discounts and free shipping.

Here's a plot of my CSL cal file vs factory miniDSP cal at 90 degrees. Take note of the y-axis scale, which makes the differences easier to see, but also exaggerates them if you don't realize how much zoom there is.

While the miniDSP does go down to 10 Hz, it's off by 2 dB by that point. From 20 Hz to around 6 kHz, miniDSP is off by up to only 0.5 dB which should be negligible. After 6 kHz, the error is mostly around 1 dB which I do feel can be slightly audible for those sensitive to higher frequencies. Of course, this is just for my particular mic; others may have greater or smaller differences. For me personally this difference justifies the small premium of the CSL mic (considering the cost relative to the processor we're talking about), but I think it's fair if anyone considers these differences minor enough to not worry about.

Can anyone comment yet on CEC & ARC stability?
How about general HDMI stability?
Mine is on the way but this is my single biggest concern.

Marc Alexander said, during his beta testing, that HDMI stability was pretty much rock solid. And I believe he stated that for his setup CEC worked near flawlessly.

He responded to me just recently that HDMI switching was very good/acceptable as well.

@pink soda it might be helpful to add a list of suitable xlr to rca cables/adapters in the FAQ & Tips section since I suspect there will be a good percentage of us using one or more of them and there seems to be a fair amount of adapters in the marketplace that aren't wired per page 8 of the manual. The correct xlr to rca cables will have pin 1 of the xlr wired to the outer contact of the RCA, pin 2 wired to the center contact, and pin 3 should be floating.

Does special wiring apply to xlr to xlr connectors? I had ordered 8 sets from Monoprice.

The Monoprice XLR-RCA cables I bought a couple of years ago had pin 3 grounded; I opened the XLR ends and snipped wires connected to pin 3.

Wonder where I would find xlrs that are already properly wired. I won’t be modifying anything myself.

Unless I’m just completely out of my mind, any XLR/XLR cable will do just fine.

What’s in question are the wiring from XLR/RCA setups, since the HTP-1 lacks any RCA pre-outs.

Cables with XLR to RCA ends need to be wired a certain way for the HTP-1.

If you’re not converting any ins/outs and you have XLR inputs on your amp - any XLR male/female cable will work.

That’s great news. That’s what I had thought from what I read previously.

Thanks, good idea. Added your description to the FAQs for now, will add specific cables/adapters as people test them out and confirm what works for them.

Maybe I missed it but has this always been dual voltage. I thought last time I checked it was 120V only as I was looking at step down transformers.

Hope it is as that will make life easier and puts it back on the radar.
