General Topics

What is the HEMC?

The HEMC is D-Box's latest motion controller.  It uses Shazam-like technology to work with any audio source (i.e.- satellite/cable, Apple TV, Blu-ray, etc.).  As long as the movie has been coded by D-Box, it will sync.  With 3,100+ titles coded so far, that's a lot to work with.  This device also boots up and is ready to go much quicker (just a few seconds) than previous motion controllers and takes up a much smaller footprint on your equipment rack.


What else do I need to purchase with the HEMC?

 1. You need to purchase a KAI-1P to convert the Cat 5e cable coming from your chair to a USB signal that feeds into one of the HEMC's four ports.

2. Unless your receiver can convert incoming audio signals to a digital 3.5mm output*, you probably need an optical to 3.5mm converter.  I recommend the Panlong Digital to Analog Audio Converter - Optical SPDIF Toslink Coaxial to RCA L/R Adapter with 3.5mm Jack.  You can get in cheap on Amazon here.**

*My receiver, an Onkyo TX-SR707 does not offer this conversion, so currently I'm limited to only using my Oppo player as a source to the HEMC.

**There are other methods to get a 3.5mm signal to the HEMC, like using RCA outputs connected to a 3.5mm conversion cable, but I do not recommend this method as the results are not dependable.  If you really want to go down the path of converting RCA outputs to 3.5mm, D-Box says you really need a signal sent to the HEMC that includes a FL+FR+Center.

3.  (Alternative to #2) If you do not have an optical output on your receiver or video processor, but you have a free HDMI output, you'll need to get an HDMI-to-Optical converter.  This device is recommended: http://www.atlona.com/HD-M2C.html


How fast is it compared to the older controllers?

When using the Panlong converter, it usually takes anywhere between 5 - 10 seconds to sync.  Compared to my old 340C, it seems to sync much faster, even when doing "trick" play (i.e.- fast forwarding, rewinding, etc.).


Are any features missing from previous controllers?

The only feature currently missing is the Audio Mode, wherein the box would attempt to rumble based upon the LFE or bass signal.  However, at CEDIA 2014, D-Box displayed a version of the HEMC app that had an "Audio Selector" feature that would attempt to create motion on-the-fly for films that had not yet been coded.  As of this writing (January 11, 2015), this feature has not been included in any public release of the HEMC app for iPad or Windows.

 

How do you update the HEMC with new codes?

You visit the official HEMC site at http://hemc.d-box.com/ and download the updates as they are released to the USB thumbdrive included with purchase of the HEMC.  Future updates to the HEMC app will likely include the ability to download the updates directly to the device.

 

How many titles can it remember for fast syncing?

The HEMC is able to "remember" up to ten recently synced films at a time for very fast syncing (~5 seconds or less).

 

What are the recommended settings for an Oppo Blu-ray Player when used with the HEMC?

Set the player's optical/coaxial output to LPCM, as this will force a down-mixed 2 channel digital signal which is what the HEMC ideally needs.

 

How do you control the HEMC? Will it work with a programmable remote control?

The HEMC is controlled by the official HEMC iPad app (iPhone version is not currently available) or the HEMC Windows program.

 

What does the tolerance control do?

Tolerance allows a locked on coding to continue for X seconds (X being the tolerance value) after the signal and/or sync is lost. D-Box recommends starting with the tolerance set to 4-5 seconds initially and adjusting as necessary from that point for non-English language tracks.

 

What is that HDMI input for?

It's not for connecting to your receiver or Blu-ray player like you would think.  Instead it is used as a way to connect the HEMC to a video monitor to access the device for troubleshooting.

 

Where can I find further information?

You can read about my initial thoughts on the HEMC here and here.
