Sennheiser AVX MKE-2 Pro System Review

The Sennheiser AVX MKE-2 Pro System is a new digital wireless sound system, that takes over from the trusty EW100-G3 wireless sound package which is used by many producers, sound engineers and in television across the globe. The transmitter and receiver packs have been re-designed, removing the cable aerial and making the receiver much smaller; more practical for on camera use or smaller setups (using a DSLR for example).

SennyAVX_1Sennheiser have also seen the increased use of these small cameras, and adapted the systems output to be a hardwired male XLR, but also includes an XLR to TRS (mini-jack) adapter so that you can go straight into the cameras microphone input rather than using an external recording device.


At BVE I used the system for some show floor interviews with exhibitors as a trial run for the setup. The receiver is much more compact, and includes a hot shoe adapter so it can sit comfortably on camera or on a cage, with the output going straight into the camera. You can check out these videos here, and it gives you a good idea of the system and microphones capabilities in a noisy and busy environment. Sony PXW-Z150 interview example and Samyang XEEN interview example.

The mic capsule build, and clarity of the subjects voice is a big improvement with the MKE 2 lavalier on the previous ‘kit’ microphone in the old EW100-G3 package, making it more versatile than having to use another microphone.SennyAVX_2

The ‘audio for video’ seems paramount in this new system with smaller hardware and simpler connectivity which makes using the kit straight out of the box really easy. With up to 4 hours battery life in the receiver, and up to 15 in the transmitter, you also don’t have to worry about switching AA batteries mid shoot or running out of charge. Although if you’re using the kit for a while it can be charged via USB on the go with a power pack.

It is a simple audio setup, monitoring the sound in camera, and certainly while filming interviews at events this little kit packs a punch, but it is more versatile than that. The transmitter automatically switches between mic and line input depending on the connection, so you can remotely capture audio from a mixing desk or other outputs too.

We are currently also working on a short video review of the product. The Sennheiser AVX definitely has become a standard tool in our news video toolkit for various cinema5D teams due to its easy setup and configuration, and the small footprint that makes it a great companion to shooting with small cameras like the Sony a7S II.

You missed the most important benefit of this system: the fact that it operates much like a DECT phone, free from any disturbance by 4G or 5G mobile neteork rollout.

We used this systeem a few times and had a wired shotgun als a back-up. In post we noticed the AVX system to be a few milliseconds late, giving us an echo and not 100% synced audio. This is likely due to the D/A conversions it needs for the transmission so I guess there’s no possible fix. Except in post…

Boris can you say anything more about this? Does it appear to be a linear, that is constant discrepancy, or is there drift, that is it become shorter and longer discrepancies? A linear discrepancy that is a constant unchanging difference can easily be accounted for either if sending it to an external recorder like the ATOMOS or in post with say Plural Eyes, which can even fix changing drift if necessary.

Joris Rens March 8, 2016

Hi Evan. It is a lineair discrepancy. You don’t need a special plugin or so, just your regular NLE to get it fixed. Move the audio about 18 or 19ms to the left, done. Still, annoying. As you can read in the other comments below.

Hi guys, yes I’ve also experienced a very small delay when using the AVX system with a recorder, which after syncing I simply adjust in the timeline. A small inconvenience. However, when using the system straight into camera I haven’t experienced any sync issues.
I can’t confirm what causes the delay though..

I made the mistake of running a standard G3 system and a AVX at the same time. Editor was not happy about the echo and having to adjust everything.

One important thing left out: The AVX system has a delay of 1-1,5 frames. Can cause echo effect when monitoring on headphones with camera. The delay is not significant when editing, but can be annoying when capturing.

Can you charge the transceiver with USB power while you continue to use it?

Yes. I have run a USB cable into it out of my v-locks while using.

19 ms latency – not very well

I rented this 3x. 1 time I had a major issue with bad, bad distortion and generic G3 wireless interference. It scared me enough to return this as “not yet ready”

No Pro here who doesn’t like the volume-pumping because of the automatic gain?

Anonymous March 10, 2016

Yes I wonder about that also.

Tobias Hiti March 12, 2016

Actually im working with this system since a few month and the latency is really a pain in the ass ! in my opinion it`s significant in post…i`ve always to sync audio and video. so far – good idea with some problems i`m okay with it.

One note, you can’t use other lavs like countryman. when the wire touches the back of the bodypack you get frequency feedback.

can someone explain the delay? I just ordered this and am now worried. Safer to match in post? Or is the delay only during shooting?
