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 or carefully count for the position number for the port you look for on the interface. The same is true for back speaker. If after all these had done and confirmed and still no sound, check the volume, you need to make sure volume on the active speaker, volume you use with an intermediate amplifier (if any), 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 but always starts with lowest audible level to avoid high volume suddenly comes out of your sound system.

Control volume on an input sound device, active speaker, intermediate amplifier (if any), volume controller on sound card, and soft volume controller e.g. EarTrumpt software.  Please make sure you always starts with lowest audible level to avoid high volume suddenly comes out of your sound system.

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.

If 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 in active state check your PayPal automatic payment. Another common problem is Sample Rate problem, the system would not work without setting your input and output devices both at 48 KHz. Finally, make sure your speakers and input devices passed all test to ensure they are working properly. And 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 hardware problem with the sound card.

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.

This is a known problem with a few sound cards we use with WindowsⓇ and PC sound card, as far as we know the electrostatic charge causes current spike that make the highly sensitive EMX real-time audio signal processor fail. Restart EMX and try again this will usually fix this problem.

This can happens to PC with heavy loading, incomplete WindowsⓇ sound system setup, external USB sound card, or two many active audio devices. Restart EMX usually resolved this problem, otherwise stop all PC sound such as music or online video you are watching make sure no App is producing any sound, close the EMX WindowsⓇ App, open WindowsⓇ Sound Control Panel to disable the EMX output device and re-enable it for reset, and start EMX. If that still does not fix the problem restart the PC and the problem should be fixed. To avoid future problems, make sure unnecessary background programs are disabled and do not runs as WindowsⓇ startup, complete the WindowsⓇ sound system setup particularly follow the instructions to disable all sound devices not used, avoid using USB sound card, and if USB sound card must be used make sure your computer is fast not heavily loaded and unnecessary programs are being closed. Another method is to split input and output devices on two different sound cards each taking a unique role so to ensure the uneven delay time problem commonly found on USB sound cards are being buffered out on two separate sound cards. For advanced user, follow the recommended system tuning guide for digital audio workstation, e.g. SteinbergⓇ CuBaseⓇ will be helpful too. Finally, change EMX to increase audio buffer size, go to Options > Change the audio device settings > click “Show advanced settings” button and choose a larger “Audio buffer size”.

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.

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.

Change the EMX input configuration to the line-in device you want to use, and log-in to EMX.

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.

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.
