TROUBLESHOOTING
Issue: I have connected the IEX-16L to the direct outputs of my mixing console, but every time the front of house mixer makes a change to the faders, it affect the level of that channel on the myMix system.
Resolution: Check the specifications of the mixing console you are using and make sure that the direct outputs on every channel are configured as pre-fader. If they are post-fader, the level coming out of the direct output will be affected by any level changes the front of house mix engineer makes. If there are available insert points, you may want to use those instead as they are normally pre-fader and pre-EQ.
Issue: I connected the IEX-16L to the direct outputs of my mixing console, but the signals are lacking low frequency, and the levels in the myMix system are low, even though I am clipping the IEX-16L input meters.
Resolution: Check the specifications of the mixing console you are using and make sure that the direct outputs are balanced. If they are unbalanced, you may be experiencing what is referred to as an asymmetrical signal – the symptoms being virtually no low frequencies and a severe lack of level. You may need to use a converter to go from unbalanced to balanced to rectify the problem. If there are available insert points, you may want to use those instead as they are normally pre-fader and pre-EQ.
Issue: I connected myMix units to an IEX-16L but do not see the channels coming from the IEX-16L on the screen
Resolution: Make sure all devices are on the most current firmware version. This typically happens when a myMix in on a firmware version less than 1.33 as these versions were developed before the existence of the IEX-16L.
Issue: I updated the firmware of the myMix and rebooted. It is stuck on the myMix logo screen.
Resolution: We have had random reports of this issue which is resolved by downloading the Cleaner file from the Firmware Updates section of www.mymixaudio.com. Place the two .blob files on a freshly formatted SD card and perform another firmware update on the affected units. This should take much less time than a normal firmware update. Reboot the myMix. You should see the firmware version that you installed prior to running the Cleaner file.
Issue: When I first connect the IEX-16L to myMix, I only see eight odd numbered channels on the myMix screen.
Resolution: The IEX-16L has a factory default channel configuration of all pairs being in stereo. As the stereo pairs in an IEX-16L take the name of the left channel, you will see only odd numbered channels on the screen. Additionally, stereo channels only appear as one “fader” on myMix units even though the audio is split left and right in the system, which is why you see eight instead of sixteen. To change the channel configuration in the IEX-16L, follow the procedure in the manual.
Issue: I recorded to an SD card, but on playback the audio skips and is sometimes distorted.
Resolution: If you record to an unformatted SD card you will experience these symptoms. Make sure you format new SD cards before recording. If you have been using the SD card in another type of system (camera, printer, computer, etc.) we suggest you format the card as well.
Issue: I have a myMix system with an IEX-16L and several myMix. The channel signal levels are very low in every unit.
Resolution: The signals coming into an IEX-16L should be set just below clipping on the unit. If signals being fed into the unit are low, then the result will be low channel levels in the system.
Issue: I bought one of the Cisco switches you recommend from a third party. I plugged it into the system and while I can see all of the channels, I don’t hear any audio.
Resolution: If you decide to source and configure your own Cisco switches, make sure you closely follow the instructions we provide on our website. On a myMix system, the audio travels on the second VLAN. The symptoms described indicate that second VLAN hasn’t been configured properly.
Issue: I plugged in a condenser microphone to the local inputs of myMix, but there is no audio.
Resolution: Condenser microphones require phantom power. Make sure you have enabled phantom power on your myMix under Settings – Inputs.
Issue: Phantom power worked very briefly, but now it isn’t working.
Resolution: On very early production units we became aware of a capacitor that was out of tolerance in the phantom power circuit. We modified most of the units that had the issue before they made it to the market, but you must have received one that we missed. Contact us and we will replace the capacitor under warranty.
Issue: I have several myMix in a system, and everyone is using different headphones or in-ear monitors. The overall level in my headphones is very low compared to others.
Resolution: Check the specifications of the impedance and sensitivity of your headphones with the manufacturer. As virtually all headphones have different specifications, everyone will have different results. We recommend headphones with an impedance of 50 ohms or less and a sensitivity of 100dB of more.

Issue: We’re using an inexpensive, unmanaged switch with our myMix system. We have 16 channels coming from an IEX-16L, and we are also using the two local inputs from one of our myMix units (for a total of 18 channels on the network). We are getting random distortion on some myMix units.
Resolution: Any more than 16 channels of audio on an inexpensive unmanaged switch can overwhelm the limited network resources the switch has available. A common symptom of an overwhelmed switch is distortion appearing randomly on the system. To adequately accommodate more than 16 channels on a myMix network you will need to use a managed switch with IGMP snooping enabled.
