Plug and Play Expansion
Using the optional Audio Port, users can plug in local sound sources such as CD players or MP3 players to expand
the system at the local room level. You can also add a powered subwoofer in any room, synchronized with the
speakers connected to the keypad/amplifier or use the Musica keypad/amplifier to control a large power amp driving
large floor standing speakers or many in-ceiling/in-wall speakers installed in a very large space.
4- Sources/ 6 – Rooms
A Musica system distributes 4 home-wide sources and up to 6 additional separate local room sources (CD player,
Cassette tape player, tuner, etc.) to 6 rooms and is expandable to 18 rooms of audio. The system is programmed to
select any available audio sources, and then distribute them to any of the 6 rooms selected. Users can listen to any
of the different sources, at the same time, in each separate room. Compensating automatic gain adjustments at the
inputs insure that all sources are distributed at equal levels.
Remote Integrated Digital Amps
Digitally controlled stereo digital amplifiers are integrated into the keypads and are located within the rooms. With this
design, minimizing the lengths of the amplifier-to-speaker cables creates better sound quality. This reduces the distortions
and sound deterioration, which are attributed to the length of the cable run. This design also keeps heat away from delicate
source components in the main equipment rack or location.
Simplified Programming – No Laptops Required
When the settings for each source have been learned into any keypad in any room, they are stored on the Audio
Distribution Center (ADC). The ADC then “teaches” all the other keypads connected to it. This prevents having to program
all the keypads in the system individually, significantly reducing the programming time required to complete the installation.
You can also upload all learned IR codes into a laptop to easily download them for your next installation. To achieve this
you must use the Musica Tools software offered by NetStreams. To download this software, please visit the Dealer
Resources area on our website at

Intelligent Power Control
When all the rooms are switched off, the main system enters into a power-saving mode. In the power-saving mode,
20 minutes after the last keypad/amplifier in the system has been shut off, the sources connected to the outlet are
also switched off. The 2-color LED of the front panel indicates the status of the system (Red: Standby Mode, Green:
Operating Mode). The Audio Distribution Center controls the power of the sources by means of relay, which offers a
dry contact output. A power strip with a dry contact trigger or a home control system with inputs will be needed in
order to use this feature effectively.
Automatic Muting
External signals such as doorbell, door phone, telephone, etc. can be detected. When these signals are detected,
the main system will enter into the mute mode for 20 seconds so that the doorbell or telephone can be heard when
an optional doorbell/phone ring detector is used. (We recommend the use of an ELK 930 doorbell and ring detector
from ELK Industries. For more information see
www.elkproducts.com or call 828-397-4200).
Musica Network
The data communication between the ADC and the room is performed via Musica’s network, which is a proprietary
modified RS-485 protocol. This RS-232 protocol offers more than 1,200 commands for the Musica system.
IP Controllable
With the R2E web interface, a 6 room system can be controlled via a flash-enabled web browser. This will allow the
user more features from one device, such as controlling all rooms individually or all rooms simultaneously.
