Multi-zone/Multi-sourceThe A4.6Ci MultiZone Preamplifier incorporates matrix preamplifier technology to provide as many as foursource components to six listening zones simultaneously. Finally, Dad can relax to the sound of his favoritemusic in the den while the kids are listening to their favorite music by the pool.Central IntelligenceThe design approach of the A4.6Ci MultiZone Preamplifier is a radical departure from that of traditional pro-grammable keypad-controlled multi-zone systems. Instead of redundantly programming each of the individualkeypads with IR commands, all IR commands are programmed and stored in the A4.6Ci. The Solo™ and Select™Master Keypad Modules, Numeric™ and Transport™ Accessory Keypad Modules, and Niles IR Sensors connectto the A4.6Ci for complete system control.Total system cost can be dramatically reduced due to shorter programming time and the low cost of the modularkeypads located in each zone.Quick and Easy Programming with PC ArchivingManual programming is quick and easy, with push buttons and LED visual prompts that lead you step by stepthrough the programming process. Additionally, with Niles Ci Archiving software, all system programming canbe archived on your PC for back-up and for use with pre-designed systems.One-Touch Operation Including System and Component Power SynchronizationOne touch of a Master Key on an IntelliPad® Ci Solo™ or Select™ Master Keypad Module tells the A4.6Ci Preamplifierto perform an intelligent sequence of IR commands for complete control of your distributed A/V system.Sync Inputs provided by the A4.6Ci sense wether the connected source components are ON or OFF. Powercommands for these source components are issued only if the source components are actually OFF, turningthem on correctly, every time. The proper input for the source component is then selected and a programmedsequence of IR commands is issued (i.e., play or favorite station).A complex mix of various brand audio/video components can be operated with ease and simplicity when usingthe A4.6Ci.Elegant and Intuitive User InterfacesThe Solo™ Master Keypad Module - The Solo Master Keypad Module is an elegant, single-gang, complete-controlsolution for the A4.6Ci.
