EAW UXA4401
The EAW UXA4401 is a Multipurpose 4channel Installation Amplifier with On-Board DSP and EAW Greybox Loudspeaker Presets.
Integrated sound, simplified
With the large catalogue of EAW loudspeakers, it’s often times difficult to find the right amp pairing. With the introduction of UXA installation amplifiers, there is now a model and configuration readily available to make accurately specifying projects both timely and straightforward. EAW UXA4401 “D” models support DANTE digital audio and networking.
Proven Reliability
UXA Installation amplifiers are based on Pascal technology. With robust electronics and support, these amps are built to last for years while providing high quality coverage for a variety of applications.

Greybox technology
Greybox technology is at the heart of the processing power that delivers control and power through the UXA/UX Series. A Greybox is an electronic file that includes everything you need to get optimal performance from an EAW loudspeaker.
The name derives from the inputs that go to make-up the file. The ‘White’ component is the user input – what the user requires. The ‘Black’ component is EAW-provided data and is locked down. Mix the two together and you get the ‘Grey’ in Greybox.
The file includes:
- Crossover settings.
- Focusing – advanced digital signal processing is used to perfect impulse response of a loudspeaker in the time domain. This eliminates horn “honk” and splashiness, creating a sound more like a studio monitor than a “PA” speaker.
- DynO – (where applicable) and limiters. Dynamic Optimization actively tracks input spectrum and power delivery, continually maximizing output and fidelity at any drive level.
- Easy configuration.
Focusing – Cleaner sound, easily achieved
On the left we have two slides. On slide one we have two graphs. Both are spectrograms, graphs showing frequency (up and down), time (left to right) and level (color, red is hotter).
In an ideal world we want a straight, thin line. This represents a perfect impulse response. However what we usually get with loudspeakers is time smear from midrange (reflections off of surrounds of midrange cone) as indicated in the top graph. In the bottom graph we get reflections from throw of horn-loaded compression driver.
Click on the forward arrow to the second slide and you will see the processed response graph (spectrogram). The graph is now clean with no artifacts. The processing has also corrected the phase (straightness of the line) so it is close to perfect.
DynO – achieve max
DynO, or Dynamic Optimization, maximizes the output of every passband. This tangibly increases output over what would otherwise be possible. DynO ensures that setup is extremely easy – just enter simple amplifier information and you’re done. The Greybox will automatically apply the correct limiting and gain adjustments given the amplifier information you’ve provided.
Software tools
Each UXA installation series amplifier may be configured by utilizing the feature rich web interface. this can be accessed either through the network control port or wirelessly. For detailed instructions on how to do so, please read through the UXA quick start guides. Greybox settings for all current EAW products come preloaded in the amp, and can be recalled once a connection is established.
APPLICATIONS
- Bars & Cafes: The combination of small size and high power per channel flexibility makes UXA4401 especially good for installing in Bars, Cafés, and restaurants.
- Restaurants: Restaurant’s use sound as part of the dining experience, and many have dynamic needs for the sound level. Some have bar areas where they need more sound pressure, and then have cosy eating areas where they need less.
- Retail stores: Retail stores have background sound (or sound branding) where music is matched to the profile of store. This leads to a wide range of sound demand – a furniture store with cool background sound, a stylish clothes shop with medium pressure or a trendy juice bar with need for more power!
- Fitness Centres: Fitness locations demand excellent sound with great system flexibility. Background tracks play in a gym & workout area, soft sounds in yoga classes – then heart racing power in the spinning & CrossFit classes!
- Hotels & Education Sites: For hotels and education sites that have auditoriums, theatres, large dining spaces, and multiple large meeting rooms – complete flexibility of available power is needed.
- Corporate: The corporate space has many different applications – open office spaces, sound for board & conference rooms, meeting areas of any size – plus warehouses, cafeteria & break areas. IP an ideal choice as one amplifier can cover all these needs.
- House of Worship: House of Worship needs reliable, high-quality amplification of voice, and at the same time the amplifier should cover a large distribution area with many specialized speakers. Due to the high quality of amplification at medium power levels and delivery superior speech intelligibility it is perfect for house of worship installations.
