Promotion for DSP device
« on: 14 Dec 2019, 10:38 am »
I am doing marketing for a new car audio DSP device but it can be configured for home stereo use (my product manager has tested it with NuPrime DACs).  The reason for posting here is that Nuprime might consider offering it as a home product, so we are interested in your feedback.
So here's the incredible deal:
Use coupon code "SE_HD8_50Off" for a 50% discount at either one of these participating dealers:
https://sonicunity.com/collections/signal-emotion/products/signal-emotion-hd-8-digital-signal-processor

https://coyote-sound.com/collections/signal-emotion/products/hd-8


To learn more, visit https://signalemotion.com/products/hd-8/
The coupon code only works once for each user, and this early adaptor promotion will end Dec 31, 2019.
*** When ordering, please provide the model of your car just in case you want to install it ***
If NuPrime ever introduce such a device for home use, or integrate it in a DAC, you will receive a 15% discount (please keep your sales receipt of HD-8). This offer is only available to this intro promotion.

The product manual explains in detail the extensive DSP features: https://signalemotion.com/wp-content/uploads/2019/12/HD-8_manual_V1.0.pdf

This is how the car device is configured for home use: https://signalemotion.com/diy-home-stereo/
(we can pre-configure the 12V AC adapter for a small additional cost of $15)

The SignalEmotion (one word) app runs on iOS and Android smartphones and it configures the DSP device via Bluetooth BLE.  The device configuration and all DSP settings can be downloaded as a file.  Signal Emotion website will provide a place for custom installers and users to upload their configurations.  We foresee an ecosystem of professionals and expert users offering preconfigure settings and systems for home and automotive use.

I think this product is geared for a multi-channel setup, not two channel. For the price of that device ($599) I would rather buy a receiver with DSP included. I have never tried Yamaha which specializes in DSP but the ones in Onkyo/Integra are pretty good:

"We actually astonish ourselves a bit that we still find the Music sound modes useful. Usually we leave DSP presets on the left because the result sounds way too artificial, but this is not the case here. The Orchestra mode effectively adds value to classical, for example. Beethoven’s Symphony n ° 9 in DSD 2.0 format via an Deutsche Grammophon SACD is in this mode very well upgraded to enveloping view in a large concert hall. A nice upgrade for a beautiful recording anyway."- From a review of the Onkyo 830:

BTW, I love Nuprime but since we are talking DSP I just wanted to give feedback  :thumb:

I think you are confusing surround sound decoding and sound effects with full DSP, take a look at the DSP settings here:

I suppose this type of full DSP is mainly useful for active crossover for home stereo, which are not used by most audiophiles.

If the manual illustrates how much can be done, it is sorely lacking in features. Have a look to see what miniDSP offers for instance.

How do we power it for home stereo use?  We need a 12 Volt wall wart and you provide an adapter for that 10 pin port?

The multi-pin port at the back of HD-8 has power and ground wires and we can configure it and connect it to the 12V AC (from 12 to 16V ok) adapter. The DIY page explain how it is done: https://signalemotion.com/diy-home-stereo/  (the adapter cable will be provided)
Many people have extra 12V adapter left over from various devices, but if you want the vendor to configure and provide it out of the box, it cost $15 extra.

  For bass mgmt. a VG thing. For the rest of the frequency range a good idea if it has ZERO sonic character. My 2 cents.

I'm always happy to see another reputable vendor, like Nuprime, come up with a DSP device for audio. After using DSP for about 15 years, it seems to me it's coming into its own now, as it's become more transparent and thus more acceptable to audiophiles.

I looked at the linked page, and it told all about the product, except what it does. What is it for?  It's nice that it's a one-box solution, an upgrade, easy to control, and can store multiple profiles. But what does it do?

The Signal Emotion HD-8 is primarily a Car DSP so it mainly deals with setting the X-over, Equalizer, Gain controls and Time alignment typically required for Car Audio. What may be interesting is that all these setups are done through a mobile app and the settings are saved in the mobile device (as config files that can be shared). When the mobile app is connected to the HD-8 via Bluetooth, changes in any parameter can be heard in real time. One can also import any of the saved settings to the HD-8, allowing a limitless number of presets. Hence, there is no longer a need to tune the setup via laptops, nor installing additional controllers to select the presets.

We do understand that a DSP meant for home use would require other tuning parameters and features and are aware of what miniDSP offers. I don't imagine we can offer the same extensive range of DSP products as they have within a short period. We need to learn from the audience what matters most. Like what Jason has mentioned, the current possible usage of the HD-8 in the home environment would be as an active X-over.

So what tick your boxes for a home DSP? It would be probably all of the below (and perhaps the kitchen sink), but we would like to understand what is most needed.

1. Myriad of tuning parameters. (This is likely where we are focused now, as x-over filter types, variable EQ freq, Q factor would be required for Car Audio as well)
2. No. of channels?
3. Room EQ and Correction?
4. Mic based auto tuning?
5. Any other?

Thanks for your questions and comment, please keep them coming. We believe integrating DSP with digital amp can create amazing result (so far, if you haven't already noticed, all NuPrime amps are ANALOG).  It is something we want to explore.

Here's what my ideal unit would have:
  • Automatic adjustment (calibration) with manual tweaking, based on mic measurements around the main listening position, not at a single point.
  • Manual control could be either by adjusting parameters of the target curve (as in Anthem's ARC) or by adding/deleting/moving points in the curve (as in Dirac). I like the Anthem approach, except that it would benefit by addition of a few user-settable PEQ points (mostly boost/cut, but maybe shelving also).
  • Number of channels: 2.2 (stereo with stereo subs).
  • Auto adjustment of sub xover parameters, sub levels, and sub phase, all with manual tweaking available.
  • Ability to store at least 6 correction profiles for different speaker configurations and/or music types.
  • On-the-fly adjustable balance control, bass and treble controls with selectable turnover frequencies, and midrange control with selectable f and Q.
  • Adjustable upper and lower limits of DSP.
  • Everything visible, able to accept user labels, and able to be stored in a file, so that old configurations could be brought back.
  • And of course, DSP done with the most advanced and transparent techniques available.

A few comments:  (1) I have tried both single- and multiple-point methods and been much happier with the latter. However, the method needs to account for both wide and narrow listening areas. (2) Automatic correction gets better, yet still we need the ability to fine-tune it. (3) Being able to adjust broad tone controls while listening is a godsend, given the variability in recordings; it is complementary to configurable DSP, as neither replaces the other.

I bit the bullet and ordered one today.  Gonna build open baffle speakers and use active crossover too :)
