Great-sounding Wireless for Guitar or Bass

Achieve the ultimate in wireless freedom with Sennheiser's ew 172 G4. Using a combination of a compact bodypack transmitter and a reliable rackmountable receiver, the ew 172 G4 system it easy to "plug in" without the hassle of onstage cable tangles. And it sounds great — you get 1,680 tunable UHF frequencies across a 42MHz bandwidth for interference-free reception. This system is highly expandable — you can link up to twelve receivers for simultaneous setup. And you'll benefit from a 330-foot transmission range and up to eight hours of operation. Beyond that, the ew 172 G4 is backwards-compatible with previous evolution systems, ensuring that your past investment continues to pay off into the future.

A transmitter made to perform with you

Sennheiser has packed many useful features into the lightweight SK 100 G4 bodypack transmitter. The SK 100 G4 has an easy-to-read graphic display, infrared sync, charging contacts, cable emulation, RF mute, an intuitive menu and much more. As features alone are no substitute for audio quality, the AF frequency response was expanded to 25Hz–18kHz for incredibly clear sound.

You can rely on this receiver

The rugged EM 100 G4 rack receiver is ready for the road with its proven transmission reliability and inspiring flexibility. A sound check mode allows you to check the audio and RF signal at any time during setup. Twenty frequency banks with 12 preset frequencies each — plus a user-programmable bank — mean you can easily run multiple channels of G4 wireless simultaneously. Beyond that, you get an easy-to-read LCD display with blue sync LED and dedicated Escape button.

Great sound from a wireless package

The ew 172 G4's cable emulator feature allows you adjust virtual cable lengths to get sound response just like a cable would provide. Another great feature for guitarists is the onboard tuner right on the display. A built-in 5-band EQ allows you to fine tune your sound even further. Bass players will be pleased with the enhanced AF frequency response; it starts at a thundering 25Hz, which will especially please players with 5-string bass guitars. Sennheiser included all the accessories you need, including a power supply unit, a rackmount kit, linking cable, an instrument cable, two antennas, two stacking elements, and AA batteries. Sweetwater knows you want a hassle-free wireless experience, with pro performance and ease of use. With the Sennheiser ew 172 G4, you get it

FANTASTIC wireless for bass

As a cable user since 1995, I was very skeptical of going wireless for carrying bass signals. I initially bought an AKG Perception 420 system, which is garbage (sadly didn't return in time). I had a pricier Sennheiser system before that, but returned because of being way more than I needed. Well, I went back to Sennheiser, as a long-time IEM user of the brand. As the more-expensive system before, this scaled-dowm version sounds just as good. It's really just less bandwith, frequencies, and a few convenience features not on board.

I honestly can't tell a difference in sound quality (compared to a cable). You know how nice it is to not be tethered to a cable, while also not knocking over and snagging things on stage? I, for the first time, jumped into the crowd, interacted, and ran around the club with ZERO dropouts. That, and the metal construction, especially on the body pack, should last a long time, just like my first IEM system did (15 years of LOTS of gigging).

I highly recommend Sennheiser...if I could, I'd endorse them.

Excellent unit

This is an excellent unit and I am very happy with the way it is working!

Great wireless mic setup

The Sennheiser wireless unit we just replaced was easily 12 yrs old. And we only needed to replace it because the antenna on the belt pack broke and you can't get replacementwith in that frequency range anymore. I ordered this new unit on a Wednesday and had it by Saturday. Took it out to church and in about 5 min had it up and running. We have 6 wireless Sennheiser units, all working flawlessly. Thanks to the guys at Sweetwater for great cust service. My new unit was missing, of all things, an antenna for the receiver. Only one in the box. I called them and in about 3 days had an entire new system sitting in my living room. They don't stock just the antenna. I sent the other one back and all is good. I've dealt with Sweetwater for many years. Not one complaint. Except for the occasional stale bit-o-honey.

From their studio-standard MD 421 II drum mic to their trusty headphones and ultra-reliable wireless systems, there are countless good reasons why the artists and engineers here at Sweetwater are quick to recommend Sennheiser products. In our personal studios, you'll find plenty of HD 280 Pro headphones, e609 Silver cab mics, and other staples, while many of us rely on EW wireless in-ear systems onstage.
