Software- and app-based control for user-friendly operation

With SpeakerCraft's mobile app or software downloaded to your device, you can browse and choose playlists, albums, artists, and song titles with any compatible source component from anywhere in your home. The MRA-664 makes it possible to listen to any source, in any room, at any time — even if someone is already listening to something different in another room. This means mom and dad can relax with smooth jazz in the kitchen while guests enjoy classic rock in the living room and the kids sing along to top 40 hits in the backyard, and each group can change their own volume and skip tracks right from their smartphones.

More control options

Along with using your existing mobile devices and PCs, SpeakerCraft offers additional wired and wireless remote interface options for the MRA-664. Their simple, CAT-5-connected sKP7 in-wall keypad provides basic, easy-to-use playback control. For a more interactive experience, use the sophisticated sTP7. This beautiful, in-wall 7" touchscreen panel provides full system control and displays metadata with compatible sources, like a network music streamer. It can even connect to the MRA-664 controller/amp via Wi-Fi for simplified installation. Or choose the sHR200 wireless handheld remote with its combination of tactile, backlit buttons and LCD touchscreen that lets you view track titles, and makes it easy to scroll through long lists of songs, albums, and playlists. 

Simplified tablet- or PC-based configuration

Thanks to SpeakerCraft's intuitive setup software, the MRA-664 is simple and convenient to connect and program. Simply connect it to an open Ethernet port on your network router, connect your sources, IR emitters, and speakers, then follow the step-by-step programming instructions on your tablet or PC to configure your system.

Expansion possibilities

To add more zones to your SpeakerCraft audio system, connect an additional MRA-664 controller/amplifier. You'll be able to distribute music to as many as 12 different rooms.

Features

Multi-Room Audio Controller: The SpeakerCraft MRA-664 is a whole home audio controller that delivers up to six unique music sources for amazing sound in six rooms of the house. This MRA-664 integrates multi-room audio along with home theater control in a way that is simple to set up and easy to use. And, for larger homes, two MRA-664s can be paired to create a six-source, 12-zone system. Additionally, all zones are equipped with fixed or variable pre-outs, making it simple to add power and volume with one of SpeakerCraft's Amplifiers (SC2-50, SC2-100, SC2-150, SC12-30, or SC16-50 - all sold separately).

6 Source/6 Zone (Expandable): The MRA-664 provides six audio source inputs (RCA) and provides four amplified zone along with two pre-out zones (separate amplifiers required for Zones 5 & 6). You can simply add another SpeakerCraft MRA-664 audio controller through system's Loop Outputs to create a more robust multi-room system with twelve zones (a maximum of two MRA-664s can be daisy-chained).

Network Connection: The MRA-664 is fitted with a Ethernet RJ-45 port for connection to your home's local area network (LAN). Use a category 5 (or higher) cable to make a connection between the Ethernet port on the MRA-664 and an open Ethernet port on your network router. Connecting the MRA-664 to your home's network allows it to communicate with SpeakerCraft controllers, Apple iOS & Android devices, as well as other 3rd party controllers (all sold separately).

Note: The MRA-664 is an IP based system and as such has no keypad connections on the rear. All user interfaces use internet protocol to communicate with the MRA-664 system through the local area network (LAN), either hard-wired or via WiFi. The MRA-664 and all user interfaces must be connected to the same local area network (LAN).

SpeakerCraft Controllers: The SpeakerCraft MRA-664 multi-room audio controller delivers amazing sound throughout the home using a simple, intuitive user interface with options that include a handheld remote, a seven-button keypad pre-programmed for zones, and a choice of touch panel devices (all sold separately). The intuitive interface renders identically across devices enabling simple and convenient control by all.

8-Channel Amplifier: The MRA-664's advanced Class-D amplifiers deliver 30 watts per channel to each of the 4 powered zones(240 watt total system power).

The terminals accept speaker wires up to 14 AWG in size.

Inputs/Loop Outputs: The MRA-664 is fitted with six stereo RCA analog audio inputs to connect your external sources. Each source input also features a stereo RCA Loop Output to connect to another MRA-644 for expanded Zone control (up to 12 zone).

Pre-Outs: If you need more power, each of the four powered zones also feature RCA pre-out connections to support the connection of higher powered amplifiers, like one of the SpeakerCraft's Amplifiers (SC2-50, SC2-100, SC2-150, SC12-30, or SC16-50 - all sold separately). A separate amplifier is recommended if you are power outdoor speakers. The MRA-664 preamp outputs can be set for fixed or variable output depending on system design. You can even use the  speaker outputs and pre-amp outputs can be used at the same time if you need more than just a single pair of speakers in one zone.

Whole House Mode: In addition to sending a different audio source signal to each Zone, you can set the MRA-664 to "Whole House Mode" so all zones playback the same audio source.

Custom Tailored Sound: Independent bass, treble, and loudness controls enable the customization of each zone to optimize performance.

Home Theater Integration: The MRA-664 can be integrated into a home theater system. All sources connected to your AV home theater receiver can be shared with the Whole House Music capability of the MRA-664 using the Zone 2 output of your AV receiver. Also, any of the MRA-664's Whole House sources can be shared with your AV home theater receiver by using the Loop Output line-level jacks of the MRA-664 connected to a source input on your AV receiver. In addition, your home theater system can be a zone on the MRA-664 by utilizing a Zone pre-amp output of the MRA-664.

Assignable IR Outputs: The MRA-664 has an IR output (3.5mm) for each source input (IR emitters sold separately). has a built-in IR database of codes to control sources from around the world. The IR database is cloud-based and is updated frequently. IR controllable sources are items like Cable or Satellite set-top boxes, Outboard AM/FM tuners, CD\DVD or Bluray Players, Media players like Apple TV and Roku, Game Systems and iPod docks.

IP Control: The MRA-664 has built-in drivers for controlling sources via Internet Protocol (IP). These drivers are built-in, tested and allow two way feedback and control of sources like Tuners\Internet Tuners built into AVR receivers from many third-party manufacturers. There are also two-way feedback drivers built-in to control media player sources such as Sonos, Autonomics, Yamaha Aventage and Logitech Music Service (LMS) based media players such as Fusion Research and S1Digital. The two-way feedback include various levels of Metadata and album art to be shown on the SpeakerCraft based user interfaces. The level of Metadata feedback is limited to the media player and music service.

Paging: This feature allows paging from a phone system, to be heard through the speakers in pre-configured zones. The zones of the MRA-664 that are on will mute so the page can be heard. The zones that were off will turn on so the page can be heard. When the page is completed, zones that were on will automatically begin playing music again and the zones that were off will again turn off.

Q
can i put one In-wall keypad controller in each room and control each room separely?

I forwarded your question to an Advisor and they responded with the following: Yes, you certainly can use a keypad in each of the 6 zones and control each room separately. You will need to connect the keypads to a PoE (Power Over Ethernet) router (soled at computer stores) and connect the router to your network. The keypads communicate to the main unit over the network, there is no physical connection between the keypad and the main system amplifier. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat.
