12 Source Buttons A quick tap of any of these buttons turns on the zone and selects a source component. Pressing and holding these buttons for longer than three seconds turns on causes all enabled zones. Also, all zones are selected to the same source component.
This is the simplest of the A4.6Ci configurations (see Figure 7). It depicts one Niles A4.6Ci MultiZone Preamplifier installed to provide sound to six listening zones. Each zone consists of one room with one pair of speakers. One Solo ™ Master Keypad Module or one Select ™ Master Keypad Module is included in each zone for user control.
Keypads and IR Sensors Keypads and IR sensors enable the user to control the Niles A4.6Ci MultiZone Preamplifier and its connected source components. The sour ce components’ IR commands are programmed into the Niles A4.
CONFIGURA TION 2 – ADDING ZONES USING MUL TIPLE A4.6Ci’s More than one A4.6Ci MultiZone Preamplifier can be used if the system requires more than six zones. A max- imum of four A4.6Ci’ s (providing up to 24 zones) can be combined to create a larger multi-zone/multi-source system.

Distributing Audio Signals Audio signals for the shared source components are connected to both the A4.
18 CONFIGURA TION 5 – MUL TIPLE MASTER KEYP AD MODULES IN A ZONE The single zone of a Niles A4.6Ci MultiZone Preamplifier can be expanded to contain multiple Solo ™ and Select ™ Master Keypad Modules, providing control from many locations within the zone.
CONFIGURA TION 6 – MUL TIPLE LISTENING AREAS IN A ZONE A single zone of the A4.6Ci MultiZone Preamplifier can be set up to contain more than one listening area (i.
20 CONFIGURA TION 7 – MORE THAN ONE ROOM IN A ZONE A zone can be divided up into as many as five individual rooms with separate On/Off and V olume controls. A Niles Silencer V olume Control located along with the Master Keypad in each room is required in addition to Niles Expanders.
CONFIGURA TION 8 – SYSTEM P AGING WITH AN EXTERNAL TELEPHONE SYSTEM A Paging Input connection is provided on the rear panel of the A4.6Ci. It provides a connection for the paging output signal of popular telephone systems for voice paging through the speakers located in the listening zones (see Figure 1 4).
22 CONFIGURA TION 9 – IR REPEA TING FOR CONTROL OF LOCAL COMPONENTS An IR Repeating System can be integrated into a room connected to the Niles A4.6Ci (see Figure 16). This enables a single IR Sensor (installed in that room) to control local components with a hand-held IR remote control.
INFRARED COMMAND COMP A TIBILITY IR control testing was conducted on many equipment brands to determine their compatibility with the A4.6Ci. T ypical A/V source components (i.e., CD, DVD, DSS, Cable Boxes, etc.) from each brand were chosen for the test.
24 WHA T IS SOURCE-POWER SYNCHRONIZA TION? The A4.6Ci has been designed to keep track of the ON/OFF condition of the three sour ce components connected to the system. This allows you to automate source components that utilize the same IR command for ON and OFF .
CHOOSING A SYNCHRONIZA TION METHOD Once you establish that all source components in the system have compatible IR commands, the next step is to choose the appropriate sync method for each component. There are two ways to detect when a component is ON or OFF: V ideo or V oltage Sync.
26 V oltage Sync V oltage sync is also a reliable method of synchronization if chosen and implemented correctly . The sync inputs can detect the control out voltage from a Niles signal-sensing product interfaced to the source component.
Light Sensing Using a light sensor (LS-1) to synchronize your components is usually your last choice, simply because the other choices are more reliable. The Niles LS-1 Light Sensor can synchronize a component by sensing changes in light. The 1 2V output of the LS-1 is then connected to the A4.
28 MASTER KEYS/SOURCE BUTTONS The Master Keys available on the Solo ™ and Select ™ Master Keypad Module and the Source Buttons on the hand-held R-4 Remote accessory (Figure 21) provide "one-touch activation" of the A4.6Ci and its connected source components.
MASTER KEY/SOURCE BUTTON EVENTS When you press a Master Key on a Solo ™ or Select ™ Master Keypad Module, or a Source Button on the hand- held R-4 Remote accessory , up to six events may occur . Event 1 This event turns the appropriate Zone ON when a Master Key is pressed.
30 MASTER KEY/SOURCE BUTTON OPERA TION The Master Key/Source Buttons have two methods for operating the system. Single-Zone Operation The first method, a quick tap of a Master Key/Source Button in a zone (holding the key/button for less than three seconds), causes only that zone to turn ON.
OFF KEY EVENTS When you press the OFF Key/Button, up to four events may occur . The first event is the Zone OFF sequence programmed by the installer for the zone that is turning OFF . The second event is factory programmed and turns the zone or all zones OFF every time the OFF Key/Button is pressed.
32 OPERA TIONAL OVERVIEW Multiple Rooms in a Zone Using an Expander and Silencers Individual-Room Operation - Multiple rooms within a zone using silencers require two short taps of the OFF Key to turn OFF that zone individually .
MUTE KEY/MUTE BUTTON The Mute Key/Button provides a method of turning the sound ONOFF for a brief moment in an individual zone without turning the zone OFF . (This also prevents the source components from being turned OFF .) MUTE KEY/MUTE BUTTON OPERA TION In a single-room zone, the Mute Key mutes and unmutes the preamplifier for that zone only .
FUNCTION KEYS/BUTTONS The Solo ™ Master Keypad Module, the T ransport ™ Accessory Keypad Module and the R-4 Remote include var- ious function keys for control of the connected source components. Figure 23 illustrates the available function keys for all of the control devices.
Important Note: Operation of identical source components is not possible using the sour ce components’ actual IR commands in a zone installed with an IR sensor . (i.e., using the source component’ s original remote control or a learning remote control programmed with these IR commands).
OPERA TING A SYSTEM INTEGRA TED WITH A HOME THEA TER Operation from the Stereo Zones Provided by the A4.6Ci User operation from the zones provided by A4.6Ci’ s, are not affected when integrating a Home Theater to share source components (see System Configurations 3 and 4).
When the Home Theater turns ON, it provides a 1 2V status signal that is connected to the Home Theater sync input on the rear panel of the A4.6Ci. This 1 2V status signal provides the ON/OFF status of the Home Theater to the A4.6Ci. The moment a valid Home Theater sync signal is present at the A4.
PLACEMENT Place the A4.6Ci on a flat, level surface such as a table or shelf, with its weight equally distributed on each of its four feet. Like any high-fidelity component, the A4.6Ci will last much longer if it receives adequate ventilation for proper cooling (see Figure 28).
TERMINA TING FOUR-P AIR TWISTED CABLE The Solo ™ and Select ™ Master Keypad Modules, the expander , and the A4.6Ci’ s system-expansion connections require a four -pair twisted cable with a one-to-one wiring configuration.
40 CONNECTIONS CONNECTING IR SENSORS An IR sensor can be connected to a Solo ™ and Select ™ Master Keypad Module in one of two ways, directly with a four -pair twisted cable (see Figure 34 and 35), or with a three-wire to RJ-45 adapter available from Niles for IR sen- sors installed with two-conductor shielded cable.
41 CONNECTIONS SOURCE-COMPONENT AUDIO SIGNALS 1. Audio Output of Source Components to the A4.6Ci Male-to-male RCA audio cables connect the four exter- nal audio sources. 2. Buffered-Cascade Audio Output of Source Components to Slave A4.6Ci’ s or a Home Theater Male-to-male RCA audio cables connect Slave A4.

43 CONNECTIONS CONNECTING AN IR SENSOR FOR LOCAL SYSTEM CONTROL IR Sensors installed in zones for hand-held IR remote control of the A4.6Ci and its connected sour ce compo- nents can also be used to control local components (i.e., a TV , DSS, DVD, and a surround-sound system locat- ed in the master bedroom zone as shown in Figure 38).
44 CONNECTIONS CONNECTING AN A/B AMPLIFIER SWITCH FOR LOCAL SYSTEM SELECTION A Niles SPK-1 V oltage-Activated Speaker Level A/B Switcher connects to both the A4.6Ci and a local system to provide sound from each system to the same speakers located in a single zone.
PROGRAMMING P ANEL IR commands needed for control of connected external source components are programmed into the A4.6Ci’ s program memory using the hidden programming controls on the front panel (see Figure 42).
INST ALLA TION AND PROGRAMMING DOCUMENT A TION Why Document? There are three important reasons why you should keep thorough documentation of the installation and the programming procedure: • It enables you to program the system properly .
Each A4.6Ci has six zones to document. Fill out one Master Preamplifier Schematic for the Master A4.6Ci, and one Slave Preamplifier Schematic for each Slave A4.6Ci in the system. Doing so determines how many zones will be installed, the name of the room in a zone, and what keypads each room contains.
W orksheets keep a detailed record of where individual IR commands are programmed, which of these IR com- mands are used in sequences (along with their page and key address), and all pertinent information regarding the Master Keys, and the OFF Key .
SYSTEM-INST ALLA TION SCHEMA TICS The first information to document is the makeup of your system. Establish how many zones are involved, and the number of preamplifiers in your system. Next, determine how many zones have more than one room, requir- ing the use of an expander .

The Expander Schematic sheet (Figure 44) enables you to document each of those additional keypads. Multi-Area Zone 51 PROGRAMMING OVERVIEW 1 JOB TITLE 2 SYSTEM DESIGNER Document the customer ’s name.
Multi-Room Zone In a multi-room zone, the information to document in the Expander Schematic Multi-Room sheet (Figure 44) is the same as in a Multi-Area Zone. The only difference is that you need silencers in all rooms for individual vol- ume control. 52 PROGRAMMING OVERVIEW 1 JOB TITLE 2 SYSTEM DESIGNER Document the customer ’s name.
Slave Preamplifier Installation Schematic After filling out the Master Preamp Schematic and any necessary Expander Schematics for the Master , you are ready for the Slave Preamp Schematic sheet (Figure 43) if the system has more than six zones. Fill out one sheet per Slave A4.

SYSTEM PROGRAMMING WORKSHEETS After documenting what is being installed (every keypad, every expander , every zone, every preamp), you can now document all IR programming used in the system. Following are detailed descriptions of the six Programming W orksheets.
W orksheets #2 and #3, Function-Keys Programming W orksheets W orksheets #2 and #3 document the IR commands stored in each of the available function keys for all 1 0 Pages (i.
W orksheet #3, Slave A4.6Ci Function-Keys Planning W orksheet W orksheet #3 (Figure 47) documents IR commands programmed into the Slave A4.6Ci’ s. Because any IR com- mand programmed into a Slave is transparent to the system during normal operation, these commands cannot be used to operate the sources.
W orksheet #4, Master-Key Sequence Programming W orksheet #4 documents the Master Key Sequences that will be performed whenever a Master Key is pressed. Indicate each step of the sequences, identifying where the IR commands were programmed by using their page and key address.
W orksheet #5, Zone On/Off and System On/Of f Sequence Programming W orksheet #5 documents the steps of the sequences that occur whenever a zone first turns on and when the zone turns off. Identify where the IR commands were programmed by using their page and key address.
W orksheet #6, Function-Key Sequence Programming W orksheet #6 documents the steps of the sequences that have been programmed into any of the available Function Keys for the Master A4.6Ci only . Identify where the IR commands were programmed by using their page and key address.
PROGRAMMING A LEARNING REMOTE FOR ZONE OPERA TION USING KEYP AD MODULES Learning remote controls can be taught the IR commands to provide individual zone operation. These IR com- mands operate the A4.6Ci and its associated sour ce components from any zone equipped with an IR sensor .
PROGRAMMING A LEARNING REMOTE FOR ZONE OPERA TION USING THE NILES R-4 REMOTE Learning remote controls can be taught the IR commands of the hand-held Niles R-4 Remote to provide indi- vidual zone operation. These IR commands operate the A4.6Ci and its associated sour ce components from any zone equipped with an IR sensor .
Method #1 – Controlling Shared Source Components with IR Repeating and 12V Home Theater Status When using IR repeating, IR programming for the source components can be accomplished by program- ming the actual IR commands from the source compo- nent’ s included remote control into the Home Theater learning remote control.
Important Note: There is no need to teach the Niles OFF command to the Home Theater learning remote control when using Method #2. As in Method #1, when the Home Theater turns off, the 1 2V signal is removed from the A4.6Ci and it now “knows” that the Home Theater turned off.
65 SETTING ALL ON/P AGE MODE There are six All ON/P AGE switches located on the hidden program- ming panel of the A4.6Ci. Each of the A4.6Ci's zones has a corre- sponding numbered switch (see Figure 40). The switches enable (up) or disable (down) the individual zones from responding to ALL ON commands and incoming audio pages.
66 INST ALLA TION SETTINGS ALL ON V olume Level When a system-wide ON command is issued, zones that are turned OFF turn ON to the ALL ON volume level set by the factory in the A4.6Ci. (Volume levels in zones that are already turned ON do not change during a system wide ON command.
