5Russound Collage System Installation Manual

Collage System

Collage is a Powerline Carrier (PLC) based whole-house audio system

for retrot applications. Its two components are the CAK1 amplied

keypad and the CMM1 media manager. A system requires one CMM1

and at least one (up to 10) CAK1.

Collage uses Gridcast® protocol to operate its internal communications.

This protocol rides on top of the Powerline communication. The Collage

uses HomePlug 1.0 Extended to deliver the audio streams, as well as the

control signals from the keypad to the sources.

Collage Keypad (CAK1)

The CAK1 is an in-wall amplied keypad with amplication for speakers.

It is powered by and communicates over the home’s electrical system.

The front of the keypad has a capacitive touchpad, click wheel and color

quarter VGA display. It also has a built-in intercom system with room-to-

room or whole house communication.

The keypad's amplier supports a minimum 4-ohm load (two pair of

8-ohm speakers using 16 AWG). The keypad's internal FM tuner uses

either the included monopole antenna (attaches behind the bezel) or

an optional 75-ohm coaxial external antenna.

The keypad is installed in a back box that is divided into two parts: a

high voltage power pocket with connection for the power supply, and a

low voltage control connection. These two installation and connection

areas are kept apart by a trade separator plate.

The power pocket and power supply are to be installed and connected

by licensed and qualied electricians ONLY. All wiring must be done in

accordance with the National Electric Code and all local electrical codes.

All back box and power pocket installation must comply with all local re

codes.

PRODUCT OVERVIEW

Media Manager (CMM1)

The Media Manager is the bridge between the Collage system keypads,

the internal home network (LAN) and the outside world (WAN). Its

job is to manage up to three streams from external services (such as

Rhapsody® Direct and internet radio services) and internal streams from

computers, NAS drives, Windows Media Connect, and the like (via DLNA

[Digital Living Network Alliance] and UPnP [Universal Plug and Play]).

The Media Manager also hosts the system's rmware and controls other

system functions.

The Media Manager is connected to the home's network via a port

on the network router/switch. In turn, the CMM1 communicates

bidirectionally with the keypads using Gridcast via the electrical wiring

by using HomePlug Powerline Carrier (PLC) technology.

Installation and conguration constraints

A broadband internet connection is required for proper operation of •

the Collage system.

Surge protectors, power strips and uninterruptible power supplies •

must be PLC-friendly and/or HomePlug approved. Other models will

compromise powerline communication.

GFCI and AFCI (arc fault) outlets may hinder the PLC performance if •

they employ ltering and surge suppression as well. Check with the

manufacturer.

Surge duplex outlets may hinder the PLC performance if they employ •

certain types of ltering. Check with the manufacturer.

The PLC protocol used in the Collage system (HomePlug) does •

not function properly when the alternate protocol DS2™ is already

being used within the home. Removing the competing devices,

or switching the competing device to the HomePlug protocol will

resolve this issue.
