Evolution Wireless Digital breaks the boundaries by providing more dynamic range than any wireless system currently on the market. Automatically securing the most reliable signal in a matter of seconds and scalable up 90 channels thanks to 56 MHz of tuning bandwidth, it’s easy to see why this wireless system is in a class of its own.

Evolution Wireless Digital

Equidistant spacing – simpler than it sounds

Evolution Wireless Digital features an equidistant tuning grid previously only found in our flagship Digital 6000 and Digital 9000 wireless systems. Quality components with exceptional linearity eliminate intermodulation between EW-D transmitters, allowing frequencies to be equally spaced every 600 kHz alongside each other. This simplifies frequency coordination for wireless beginners and seasoned professionals alike, and also contributes to the system’s scalability and impressively high channel count.

    While the microphone appears to be functioning well, the packaging arrived in poor condition. The box was covered in tape all over, and the contents inside were disorganized and covered in dust, giving the impression that it had been opened and handled multiple times, resembling used items in a disorderly state.

    鶹 Vine Customer Review of Free Product( What's this? )
    Requested this because the included 835-S handheld mic has a great reputation as an SM58 alternative, plus having a wireless mic in your arsenal can be very handy.

    That being said, this is way beyond a simple receiver/transmitter kit.

    Build quality is up to Sennheiser standard, I’m a huge fan of their headphones (which have lasted me the better part of a decade). The microphone is very sturdy, with a decent weight that is still comfortable to hold. Feels slightly wider, perhaps due to being large enough for the 2xAA batteries inside. Nice having a standard battery type, and they seem to last a while. Sennheiser states 8 hours, which sounds about right (battery level was at 78% after about 90 minutes).

    The receiver is compact but sturdy and there’s a rack mount kit in the box. Included power supply is pretty ordinary but they include adapters for pretty much every country’s outlets. Display is bright and CRISP. You can read it from pretty far away.

    I jumped into this without the manual and had the mic paired up in seconds. Power on the receiver, power on the mic, tap sync in the receiver then sync on the mic. Done.

    Luckily I DID read the manual too because that’s how I found out about the smartphone app. The receiver can connect to your iPhone via Bluetooth and the app lets you manage the receiver, help add new transmitters, and also update firmware for both receiver and transmitter units. Updating the mic took about a minute, the receiver took closer to 2 minutes.

    Recordings from the mic are clear. The mic comes with a clip but even handheld the handling noise was effectively zero. Very impressive. The 835-S isn’t an SM58 but I found it suited my voice well when singing through it, with the recordings sounding pretty darn good (connected the receiver to an Audient iD44 via XLR, recording into Logic on an M1 Mac). I also did some testing to see how well the receiver could track the mic while I walked around, recording myself as I went between rooms in the house, downstairs, outside, etc. Solid performance, although walls and floors are (understandably) problematic and cause drop outs. The manual even mentions the use of external antennas to help work around issues relating to walls at venues etc.

    Transmitter packs for your guitar / instrument are available too, which can also be paired to the same receiver and managed through the app (which shows you the battery level, neat). Scalability is pretty impressive.. if I’m reading it right, you could pair up to 16 transmitters.

    Overall, complete overkill for my current needs (especially during a pandemic) but being able to gig with a pro level wireless system is a blessing.

    No complaints. Sennheiser gear is solid. 5 stars.
