EMX Software Setup Guide


Before you start, make sure you have these equipments ready:




Step one: install sound card, driver, and test with the speakers


First of all, follow sound card manufacturer instructions to install the sound card and its driver to your PC.

Start simple, turn off all virtual surround, and sound enhancement effects provided by sound card manufacturers, e.g. Sound Blaster ® SBX ®, CMSS, Scout Mode ™, concert hall reverb effect etc. You can turn them back on after EMX installation.

Next, follow these steps to test the sound card with your speakers:
  1. Connect your speakers, and position them correctly. You may find speaker positioning guideline on our website. (Video Step 1.1)
  2. Open the Windows Sound Control Panel. (Tips 1), select the “Speaker” device of your 5.1 sound card, and click the “Configure” button to test and to ensure these speakers make clear and loudness balanced sound, loudness balance means you should adjust speaker volumes to make same loudness for all speakers (Tips 2). Click cancel to exit. (Video Step 1.2)
  3. Select the same “Speaker” device, click the “Properties” button, select “Advanced” tab, choose a 48000 Hz item, and press “OK” to save the configuration. Click Ok to exit the Sound Control Panel. (Video Step 1.3)

Step two: install a virtual cable software


Download and install free software Virtual Audio Cable (VAC) Lite from software.muzychenko.net, or simply click here to download VAC Lite v4.64. This is the latest version which works well with EMX.

VAC will creates two virtual devices, playback device name "Line 1", and recording device also name "Line 1". And this playback device should set as Windows default, so that all PC sound signal will be captured and being sent to the recording device. Follow these instructions:

  1. Save the zip file inside a file folder. Extract the zip file, and double click the file setup64.exe to run the installation program.
  2. At the end of installation, it ask whether you want to "Open System Audio Properties window now?", say Yes. And the Windows Sound Control Panel will open, new playback device "Line 1" is already set as Windows default for you. Now click OK to save and close it. (Tips 1)
  3. Finally, to configure VAC run VAC Control Panel (Tips 2), select the one and only one cable, check the box "Volume control", and press "Set" button to save the setting. By default VAC does not response to keyboard volume control, now the problem is fixed. Exit the VAC Control Panel.
You had just installed VAC Lite, in the next step you will install and configure EMX so it can takes the sound signal from this recording device for further processing.

Step three: install and configure the EMX software


Download EMX, install it, and get a user account. If you do not have a user account, click here to get one month free trial.
  1. Run the EMX software and make sure you are signed out. (Video Step 3.1)
  2. Show the Internal Connections page. (Video Step 3.2)
  3. Play some music and configure the EMX software. (Video Step 3.3)
  4. To turn-on and test the sound system, adjust volume using the volume control on your sound card (Tips 1), log in to your EMX user account, and you should instantly hear sound come out of all speakers. (Last Video)

At first you may notice Endpoint Mixing makes different sound at each speaker, and the two front speakers make sharper sound than the two back speakers.

Troubleshooting



No you don’t need it. The only instance is unstable PC suffering memory constraint would works slightly better with the full featured version bit perfect 1 millisecond configuration, but this is highly unlikely for most users.

Use physical volume control on top of your sound card, on the first row of your keyboard, or use soft control at the lower right corner of your screen.

Increase/decrease volume at the front speaker to increase/decrease high frequency range response, increase/decrease volume at the back speaker to increase/decrease low frequency range response. For 3D applications, loudness lean towards the front enable stronger sense of closer objects and verbal conversations, whereas loudness lean towards the back enable stronger sense of ambient and low frequency objects.

You may use speakers from an integrated 5.1 sound system with component analog input (i.e. 6 separate analog audio RCA inputs), both front and back stereo speakers are being purchased from the same manufacturer with the same model number, or try to match similar power level, sound characters (warmth vs precision and etc.) and design between front and back stereo speakers as much as you can. Another consideration is audible time delay difference, this should rarely happens. But if this is the case, replace one of the two stereo speaker to close the gap. Finally, make sure you place your speakers according to the speaker positioning guideline and do not erroneously patches front sound to back speaker and back sound to the front speaker. Finally, since input signal is providing to the Endpoint Mixing Subwoofer output without alteration (signal is provided this way so active subwoofer could have more freedom to perform own low-pass signal processing), another possible problem is that user erroneously patches subwoofer sound to front and/or back speaker.

Endpoint Mixing Layer 1 sound technology is a 2.2.1 (or 4.1) sound system, meaning 2 front 2 back and 1 subwoofer channels. There is no center channel. Center/SubWoofer (CEN/SubW) port of a 5.1 / 7.1 sound card is being used as subwoofer left and right output. If your active subwoofer has one input channel, usually a single RCA, then either one of these channels can be used to connect with the subwoofer.

First, make sure speakers is working properly, you may isolate the speaker and test with a direct audio input. Next, make sure audio cable used between sound card and speaker is good and finally make sure the correct output port is being used, usually sound card port will be labelled as L/R (or FL/FR) which means stereo left/right (or Front left/right in surround terms) which is what you look for with Endpoint Mixing front speaker, a user manual provided by sound card manufacturer will gives you which label to look for, carefully count the position for the ports you look for. If after all these had done and still no sound, check the volume, you need to make sure volume control on the speaker/amplifier, and soft volume control which includes master Windows volume and the Levels tab for the devices you are testing at the Windows Sound Control Panel are loud enough. Please make sure you always starts with lowest audible level to avoid high volume suddenly comes out of your sound system.

If the devices is not found, make sure your sound card and driver are both installed properly, use test interface provided by sound card manufacturer to confirm. If the device is found on the Windows Sound Control Panel but not functioning properly please contact Microsoft and sound card manufacturer for further assistance.

Check your EMX device settings (Options > Change the audio device settings) and remember the names of your input device and output device. Goes to Windows Sound Control Panel (Click the Windows icon on the taskbar type “mmsys.cpl”) look for the sample rate settings under Advanced tabs of the devices you’ve just identified. Make sure they are both working at 48 KHz and the output devices has at least 6 channels.

If the devices is not found, make sure your sound card and driver are both installed properly, use test interface provided by sound card manufacturer to confirm. If the device is found on the Windows Sound Control Panel but not functioning properly please contact Microsoft and sound card manufacturer for further assistance.

A standard music CD produces 44.1 KHz at 16 bits bit-width for each channel, as it is designed for stereo sound reproduction it means 2 x 44.1 KHz / 16 bits. Endpoint Mixing used its algorithm convert input source to four channels at real-time which means 4 x 48 KHz / 16 bits with 44.1 to 48 resampling. With the help of two layers of speakers (front and back layers) it means it is an order of magnitude increase in sound quality. However, as we are already testing the premium services in our lab, 96 KHz, 192K Hz and 384 KHz increases in sound quality at another levels on scale.

First double check to make sure your Windows ® default playback device is set to VAC “Line 1” playback device. If during EMX sign-in you see an error message, follow the instructions, there are two type of errors, error related to your account and subscription, error related to your PC and speakers. Common problems includes inactive account, when this happens you need to make sure your account is back to active state, you may need to check your PayPal automatic payment too. Another common problem is Sample Rate problem, the EMX software would not work without setting your input and output devices both at 48 KHz. Finally, check your speakers to ensure they are working properly. Make sure you consult Windows user manual in particular Windows sound system and seek support from your sound card manufacturer if you think there is other hardware/software problem.

Make sure the operating system is updated to the latest version. For Windows ® 10 and and Windows ® 8.1, please update to at least after January 2021. Make sure all configurations goes correctly according to the installation guide. If problem persist, try disable useless playback devices at Windows ® Sound Control Panel. If problem persist, try use different EMX buffer size which the setting is located inside the advanced configuration of EMX. If problem persist and you are using internal add-on sound card such as Sound Blaster Z, then there is possible hardware incompatibility issue, change to onboard 5.1 sound card or use an external sound card e.g. Sound Blaster OMNI 5.1, Logilink which are certified as “EM Ready” and these sound cards has no reported error after extensive testing. Please read the “EM Ready Product Guide” available on our product page for more information.

EMX should be able to operate non-stop for months, but if you notice EMX is not working, for example the Frequency Response Graph is not moving, then just restart EMX and try again, the problem will be fixed.

Just restart EMX and try again, the problem will be fixed.
