INTRODUCTION

Congratulations!

You’ve just taken the first step in entering the new world of audio technology by purchasing the NetStreams’ Musica Audio Distribution System. We’d like to take this opportunity to thank you for your purchase and provide you with an introduction of Musica followed by some important installation notes.

Overview:

A standard Musica system is a fully self contained 4 source, 6 room audio distribution system that can be expanded to 18 rooms of audio. NetStreams combined an LCD based keypad controller with compact but powerful internal amplifiers designed to wall-mount in a standard two gang footprint. By locating the amplifiers in the room, close to the speakers, Musica’s internal amplifiers greatly reduces power loss. The LCD display on the Musica keypad gives you instant visual feedback every time you press a button. Even when controlling sources located in another room, the display provides a clear indication of the action performed. For example, most of the sources to be controlled don’t feedback information. If you can’t see the front panel display, you don’t know if the CD player received the ‘Play’ command from the remote control. With Musica, if you press the ‘Play’ button on the keypad, you will see a ‘Play’ icon right on the LCD confirming the IR message was sent.

The design goals for NetStream's Musica system were deceptively simple. Create a system that makes it easy to listen to music anywhere in a home or building, with exceptional musical fidelity. The Musica Audio Distribution system is:

 Easy to Install  Easy to Operate  Capable of playing up to four different sources independently and distributed to as many as six rooms  Keypad with the latest Texas Instruments’ “Pure-Path” Digitally controlled amplifier  Burr-Brown  Handheld IR remote control which emulates the keypad  Audio Port (EIM) allows local sound sources to be played at local room level  Expandable to 18 rooms with additional ADC’s  Web enabled with the R2E (6 zone system only)  Remote Digital Amplifiers

Analog to Digital Converter for audiophile sound quality.

Information on RS-232 protocol and advanced integration with products such as; AMX, Crestron, and Vantage can be obtained on the NetStreams website at www.netstreams.com.

Once again, thank you!

This manual assumes that the installer has completed training such as CEDIA Boot Camp and knows how to install audio keypads, connect audio components and utilize basic installation tools such as a punch down tool to terminate Cat 5e wire. It also assumes the installer has pulled all necessary wire to the locations where the ADC, keypads and speakers are to be installed. If this is not the case we highly recommend that the installer attend training prior to attempting the installation or that the installation is referred to a qualified installer. Please contact NetStreams Technical Support at (512) 977-9393 for further information or assistance.

FEATURES

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 www.netstreams.com

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.

MUSICA KEYPAD AMPLIFIER OVERVIEW

The interactive wall-mounted keypad/amplifier features a wide-screen graphic LCD that aids in easy operation of the system by providing feedback to the user on the status of the system. It responds visually to any press of any button confirming the action to the user. The menu screen uses a “look-and-follow” window-style menu and adds aesthetic value to the user’s living environment. The keypad also features an IR sensor that receives the system’s remote control as well as the original remote controls of the audio sources. This IR sensor also allows for the pass-through of other IR.

Please Note: If connecting 4602 keypad with 4601 system please see App. Note note109 at www.netstreams.com.

Wide-screen High Resolution Graphic LCD

The wall-mounted Keypad uses a large (Active View Area: 1.41" x 0.78") graphic LCD that displays the state of all sources and rooms and provides instant visual feedback for all commands.

Remote Digital Amplifier in each Room

The digitally controlled amplifiers are integrated to each keypad and are located within the rooms to ensure superior sound quality. Minimizing the lengths of amplifier-to-speaker cables minimizes the distortions and sound deterioration that can be attributed to the length of the cable in conventional designs. Musica’s architecture places the amplifier in the room where the audio will be played – close to the speaker, achieving maximum wattage, with minimal noise and distortion. The high quality pre-amplifier in the system provides the controls for fine adjustments of bass, treble, balance, loudness and volume in each individual room.

Simple Source Selection

Using a button labeled SRCE, the sources can be browsed and selected.

Easy Volume Control

Pressing the UP and DOWN button provides very fine control over the volume with a resolution of 35 steps. When the UP or DOWN buttons are pressed the LCD automatically switches to the volume level view for 1.5 seconds for confirmation of the button presses and then switches back to the previous view.

Menu-Driven Design

Below is a list of the available pop-up style menus:

SOUND Adjusts the bass, treble, balance and loudness contour of the sound.

•

• STORE Stores the name of the audio source by user’s selection (CD, Tape, DVD, Classic, Pop, etc.)

SRC (Source Remote Control) registers the buttons of the source’s remote controls to the SRC keypad.

•

B.L (Back Light) Selects the color (green or amber), adjusts the brightness, timer and the on/off mode of the

• backlight.

R.OFF (Room Off) Accesses other rooms in the system to turn them off.

•

• EXT (External Audio) Controls direction of the audio signal (input/output) of an external component such as a

local room audio source when the room is expanded utilizing the Audio Port (EIM).

MUSICA KEYPAD AMPLIFIER OVERVIEW

Source Functions

The wall-mounted keypads come with a group of buttons designated as a direct user interface to the audio sources. It functions as a control for the 4 different home-wide audio sources. Once the buttons have been programmed, these buttons control the audio source currently selected from that room. When the settings for each source have been learned at any wall-mounted keypad, they are then stored in non-volatile memory in the ADC. All settings are then available across all rooms without any additional programming.

Room Control and System Status

One room can monitor the state of all other rooms and cut off the power of other rooms remotely. The at-a-glance display allows easy operation of all rooms from any location in the home. The menu functions of any keypad can be locked out by pressing the sequence 1, 9, 2, 3 at any keypad to prevent unwanted changes being made to the settings for that keypad. To reactivate the menu function, from the remote control press the

Plug & Play Expansion

Using the optional Audio Port, users can easily add external sound sources and output devices to expand the system at the local room level. When the Audio Port is connected, the keypad detects it automatically and displays it in the menu view. The user can now select it using the source button. The sources can now be browsed and selected in the following sequence as an example: TAPE, CD, AUX, TUNER,
