Functional Specifications
Powerful, efficient Class-D Amplifier
Number of zones: 6 for the Juke-6 (12 channels), and 8 for the Juke-8 (16 channels)
For applications requiring more than 8 zones, multiple Jukes work together automatically (e.g. a Juke-6 and a Juke-8 will appear on the network as if they were a single device with 4 sources and 14 zones)
Number of devices that can play simultaneously: 4
Number of users: unlimited
Wireless input types: Airplay (e.g. from iPhones, iPods, iPads and Macs) and Spotify Connect, implemented using robust open-source libraries
Easy-to-use Web interface that behaves just like an app but without the need to install anything
Stream audio to any combination of zones simultaneously
Analog inputs: up to two line-level analog stereo sources using optional USB interfaces (sold separately)
Can be connected to surround-sound amplifiers, also using an optional USB interface (sold separately)
Installation Overview
Once ceiling, wall or other speakers are installed in your home or building, simply connect the wires to Juke’s terminals and connect Juke to your network
Installation typically takes 30 minutes or less and requires no special knowledge or training
Administrator login allows naming of your zones (e.g. kitchen, living room, master bedroom, etc.), setting relative zone volumes, etc.
If you have a room with a surround-sound system, Juke can work with it: follow our instructions so that both systems can play the same audio
User Interface
Play audio directly from any app (e.g. Apple Music, Spotify, SoundCloud, Amazon Music, Pandora, Podcasts, YouTube, Spectrum TV, DirecTV, web pages, etc.)
Stream to Juke via Wi-Fi
Click the locations you want
Control the volume with the volume controls on your device just like you always do

Protective Functions
Output current limiting, output short-circuit protection, over-temperature, under-voltage and over-voltage
Amplifier Power Output:
40W peak per channel (80 W peak per zone). RMS power: 20W per channel (40W per zone)
Aggregate output power of zones operated simultaneously: ~400W peak
Network connections
Ethernet via an RJ-45 connector, or
Wi-Fi using WPA2. Note: Juke should be within 10 to 15 feet of an access point, otherwise we recommend using a TP-Link N300 and connecting Juke to its Ethernet port

Lots of horsepower for future firmware feature additions
Processor: Quad Core, 1.2 GHz
1 GB of RAM
Firmware
FLASH based
Upgrades are provided OTA (over the air)
LIMITATIONS
We designed Juke to do one thing really well and really inexpensively: provide great audio throughout a home or building primarily from Apple or Spotify-Connect devices that stream wirelessly
Except for Spotify, support for Android and other operating systems currently requires third-party software applications (e.g. DoubleTwist Pro, AirMusic) or third-party hardware piece (audiocast) that allow these devices to stream from popular platforms like iHeartRadio, Pandora, Amazon Music, etc.
Juke has no analog inputs, although it does support inexpensive third-party USB interfaces that provide them
It is not a surround-sound amplifier, although it can be configured to work with them to provide simultaneous audio in theater rooms and any combination of other rooms
Juke doesn’t control home automation or lighting control systems, but does have a protocol available to developers so it can be controlled by third-party home automation systems
Bottom line: our philosophy is “Sound Made Simple.” Ease of use is more important than bells and whistles. We think you’ll love it!
