Introduction
The RVL-6 is a modular multi-room control system. It combines the benefits of a remote controlled speaker selection/vol-
ume control/infrared repeater system into one low-profile chassis. The RVL-6’s unique modular design enables you to
design your system to suit your needs. Each RVL-6 can be configured for up to six rooms, and four RVL-6s can be linked
in a single system to control up to 24 rooms. Each room is assigned an insertable room control module (sold separate-
ly). Choose between a volume control module (includes room on/off control) and a basic room on/off module. You pur-
chase only the room control modules required for your system.
The RVL-6 can be integrated with Niles keypads, programmable IR keypads (the Niles IntelliPad™), IR sensors and pow-
erline carrier controls to deliver the optimum level of control for each room.Additionally, the RVL-6 interfaces with Niles
automation products for total convenience.
You’ll never have to worry about overloading an amplifier powering an RVL-6. The RVL-6 constantly monitors which
speakers are playing and selects exactly the right amount of impedance protection for your amplifier.

Features and Benefits
High-Power Handling
The RVL-6 is designed for amplifiers rated at 150 watts per channel continuous (RMS) power. Massive copper
traces on the printed circuit-board handle large amounts of amplifier current, ensuring high dynamic-range and
clarity. Isolated left and right channel ground returns make the RVL-6 compatible with virtually any amplifier.
Independent Control for Room ON/OFF, VOLUME UP and VOLUME DOWN Commands
The RVL-6 ROOM ON/OFF and VOLUME UP/DOWN commands enable you to control the room you are in
without affecting the rest of the system.You can fine tune your listening area without disturbing others in anoth-
er room.
Global ALL ON and ALL OFF Command
DIP switches on the rear panel of the RVL-6 enable you to individually choose which speakers turn on when
the ALL ON command is received. Every room in the system enabled via the ALL ON DIP switches can be
turned on instantaneously by issuing the ALL ON command. The entire system can be turned off from any
location by issuing the ALL OFF command.
Total Front-Panel Control
The front panel buttons of the RVL-6 enable you to control ROOM ON/OFF and VOLUME UP/DOWN (pro-
viding that the correct control module has been installed. When entertaining family and friends, whole-house
speaker volume changes are easy and convenient.
Keypad and Hand-Held Remote Control
The RVL-6 can be operated by optional Niles wall-mount keypads (RP-6, RP-7, or the IntelliPad) and/or via
Niles IR sensors with hand-held remote controls. The front panel IR sensor of the RVL-6 enables you to con-
trol virtually every aspect of your components using a hand-held remote control.
Teaches Learning Remote Controls its IR Commands
All IR commands required to control the RVL-6 can be taught to a learning remote control via the the RVL-6’s
teaching IR flasher. This conveniently integrates control of your source components with control of your RVL-6.
IntelliPad-Ready with Power Status Feedback
The RVL-6 communicates the status of each room module to a corresponding IntelliPad, Niles’award-winning
programmable IR keypad system. Each IntelliPad in the system displays and controls whether its room is on or
off. The IntelliPad’s power synchronization circuitry enables you to create one-touch synchronized sequences
to automate your system.
Powerline Carrier Control
Using an optional powerline carrier controller (X-10®or Leviton Decora®Home Control) you can control the
RVL-6 through the existing 120V AC electrical wires in your home. An optional NilesTW-523 interface mod-
ule (Niles stock# FG00256) is required.
4

Modular Construction
The RVL-6 uses insertable room control modules for each room you wish to control giving you optimum flex-
ibility when designing your system. With a single RVL-6 chassis you can control up to six rooms by installing
either an RVC-1 VOLUME CONTROL module (Niles stock# FG00247) or a simple RSS-1 ROOM ON/OFF
module (Niles stock# FG00248) for each room. You purchase only the number and type of modules you need.
Easy System Expansion
Up to four RVL-6’s can be linked to control systems with up to 24 rooms. When linked, GlobalALL ON or ALL
OFF commands affect the entire system. In addition, IR commands can be routed to common source equip-
ment from any of the 24 rooms.
Computerized Amplifier Protection
The RVL-6’s programmable microcontroller constantly monitors which room modules are on (you specify each
speaker’s impedance, see page 15) and their volume level, then calculates the total impedance and provides
the minimum impedance protection your amplifier requires (you specify your amplifier’s requirements, see
page 15). This extremely accurate handling of impedance protection maximizes the power for your speakers
at all times, while protecting your amplifier from overloading.
Automatic Audiophile Bypass
When only one pair of speakers is playing, the RVL-6 bypasses the impedance protection circuit. This creates
the purest possible circuit between the amplifier inputs and the speaker outputs.
Control Output
The 12V DC CONTROL OUT and an optional NilesAC-3 voltage-activated AC power switching system (Niles
stock# FG00242) enable your amplifier/receiver to turn on automatically when any of the RVL-6’s room mod-
ules are turned on (the amplifier must have a “latching” power switch and non-volatile memory, see page 21).
When all of the room modules are turned off, the AC-3 and the amplifier/receiver will be turned off automati-
cally after a 30 second delay. This delay enables the equipment to remain on if an ALL OFF command was
inadvertently issued.
Confirm and Status LEDs
The CONFIRM LED flashes green when the RVL-6 receives any IR command. The ROOM STATUS LEDs light
green when a room module is turned on. When a green ROOM STATUS LED blinks the corresponding room
module is “selected” and ready to be controlled.
Room Identification Labels
Recessed areas above the ROOM STATUS LEDs and buttons accommodate room identification labels enabling
you to custom label each room. Seventy-two adhesive-backed room labels are included with your RVL-6.
Proudly Made in the USA
The RVL-6 is made in Miami, Florida and comes with a limited two year parts and labor warranty.

Getting To Know Your RVL-6
Because the RVL-6 presents an extensive amount of configuration possibilities it is important to become familiar with all the
features and options that are available. A good understanding of the anatomy of the unit will enable you to optimally create,
configure and install your system (see Figure 2).

The Room Control Modules
Overview
For each pair of speakers you wish to control you need to a install a room control module (sold separately).
The RVL-6 accommodates two kinds of room control modules—an RVC-1 module which controls volume and
room on/off and an RSS-1 which only controls room on/off.
RVC-1 Volume Control Module
Provides room on/off and volume control. It utilizes Niles premium quality autoformers that have twelve pop-
free steps and 42dB range of attenuation. Use an RVC-1 module for any area where you would like to adjust
the volume level independently without affecting other rooms throughout the home.
RSS-1 On/Off Module
Provides room on/off control. This module is useful for areas where a Niles in-wall volume control has been
installed or volume adjustment is considered unnecessary.
Step by Step Installation
• CAUTION: Power to the RVL-6 must be disconnected.
• Remove the four screws located on each side panel of the RVL-6. Then remove the two screws located on the
top cover of the RVL-6. Carefully lift the top cover straight up. Place the cover and the screws in a safe location.
• Insert the multi-pin connector of the control module into its assigned socket. There are six sockets total, one
for each room module. Viewed from the front of the RVL-6, the first slot on the left is for Room 1, the sec-
ond slot is for Room 2, and so on (See Figure 3).
• Secure the room control module to the unit using the supplied screws. This guarantees proper alignment of
the connectors.
• Repeat the previous two steps until all of your room control modules are installed.
• Carefully place the top cover back onto the RVL-6 and replace the top and side panel screws.

Making the Connections
Speaker-Level Connections
The AMP input
• The AMP input connects to the speaker level output of your receiver or amplifier (see Figure 4).
• The amplifier or receiver must be capable of driving a 4 Ohm load.
• Some receivers or amplifiers may have multiple speaker outputs (i.e. speaker A and speaker B. The RVL-6
replaces the internal switch of the amplifier, it does not augment it.). Only one output should be used
when connecting to an RVL-6.
• Most tube-type amplifiers require that they be connected to a load at all times. If using this type of amplifi-
er with the RVL-6 you must add an external dummy load by inserting a 150 Ohm five watt resistor across
each output of the amplifier (see Figure 5).
Figure 4
Connecting an amplifier to the RVL-6
8
Figure 5
Connecting a tube-type
amplifier to the RVL-6

Room SPEAKER Outputs
• The SPEAKER outputs connect to the room speakers (see Figure 6).
• Each room pair of speakers must be home run (wired directly) to its assigned SPEAKER output connector.
• When installing an IntelliPad do not use the IntelliPad’s internal speaker relay (place the speaker relay
jumper in the disable position). The RVL-6 will locally mute the speakers.
• The RVL-6 can handle a total combined power of 150 watts per channel.
Avoiding Interference
• Wires can act as an "antenna" for electrical noise. Locating RVL-6 wires too close to a light dimmer or switch
may cause a buzzing or popping sound to be heard through the speakers. If you must locate the RVL-6 wiring
near electrical devices, route the wires several feet away from the electrical wiring.
Recommended Speaker Wire
• For most applications, it is recommended you use 16 or 18 gauge, stranded copper speaker wire. For wiring
runs longer than 80 feet, 14 gauge wire is recommended. Using speaker wire larger than 14 gauge is not rec-
ommended—the wire may not fit into the RVL-6 connectors.
• Never use solid-core, aluminum, or "Romex" type wire with the RVL-6.
• When running speaker wires inside walls, most states and municipalities in the U.S. specify that you must
use a special type of speaker wire. Usually, the requirement is that the wire has a specific "CL" fire rating,
such as "CL-2" or "CL-3". Consult your Niles dealer, building contractor, or local building and inspection
department if unsure about which type of wire is best for your application.

Making the Room SPEAKER Connections
• CAUTION: Disconnect power to the RVL-6 and the amplifier.
• For your convenience, the AMP input connector and all SPEAKER output connectors on the RVL-6
are removable.
• Strip 3/8” of insulation from the end of each wire.
• Tightly twist each wire end until there are no frayed ends.
• Insert each wire into the appropriate hole on the connector terminals following the Speaker wiring
convention (see Figure 7).
• Tighten the screws which lock the wire into place.
Connecting to Room IR Sensor/Keypads Using the SENSOR Inputs
There are many ways to control your RVL-6 system. Each location may have a different method depending upon the
level of control desired. You can choose from Niles hard-wired push-button keypads (RP-6 stock# FG00267 and RP-7
stock# FG00281), Niles IR programmable keypad (IntelliPad stock# FG00634), or Niles IR sensors. One keypad can be
combined with one IR sensor within the same room (see Figure 8). If a particular room requires two or more IR sensors
or two or more keypads you must install a Niles XRP6+ IR Expansion Unit (Niles stock# FG00638)
Avoiding Interference
• Avoid locating any of the cables, sensors, keypads or the RVL-6 near any potential sources of Electro-Mag-
netic Interference (EMI) such as light dimmers, speed controls for ceiling fans, electrical ballasts, television
sets, large motors, heaters or air conditioners.
Room Status Feedback Signal
• When a particular room control module is on, the RVL-6 outputs a status signal on the corresponding
SENSOR input.
• The Niles IntelliPad utilizes this status signal to automate room turn-on and room turn-off.
• Some Niles IR sensors (IRR4D+, IRR4S+, and TIR1+) utilize the signal to indicate the room’s on/off status.
Recommended IR Sensor/Keypad Cable
• Each room must be home run (wired directly) to its assigned SENSOR input (see Figure 8).
• The RVL-6 connects to IR sensors and keypads using 2-conductor shielded cable with a drain wire.
Recommended cables are “data grade” cables made of two 22 gauge (or larger) conductors surrounded by
a foil shield and a bare drain (ground) wire. Data grade cable provides the capability for runs of up to 500
feet to each sensor. Examples are West Penn D291, Belden 8761 or Carol C2516. Any 22 to16 gauge 2-con-
ductor shielded cable with a drain wire will accommodate 150 foot runs to each sensor and is available at
your local hardware store.

Distributing IR Commands Between Units Using the IR DATA IN and IR DATA OUT
The IR DATA IN and IR DATA OUT are used to cascade IR data (TTL level, active high) from one unit into the next.
IR DATA IN
• The IR DATA IN routes an IR command to four locations within the RVL-6— the IR DATA OUT, the COMMON
FLASHER outputs, the DEDICATED FLASHER output, and the Room 1 control module (see Figure 10).
• MODE DIP switches on the rear panel of the RVL-6 enable the blocking of an IR command to two of the
locations—the DEDICATED FLASHER output and the Room 1 control module (for more information see
Setting the MODE DIP Switches on pages 16 and 17).
IR DATA OUT
• The IR DATA OUT is an outlet for IR commands received from any of the RVL-6’s SENSOR inputs, built-in
IR sensor, and the IR DATA IN (see Figure 11).
• DIP Switches on the rear panel of the RVL-6 enable the blocking of an IR command from the RVL-6’s built-in
IR sensor and IR DATA IN (for more information see Setting the MODE DIP Switches on pages 16 and 17).
Controlling Components Using the IR FLASHER Outputs
The IR flasher outputs on the RVL-6 are used to drive Niles IR flashers which retransmit the IR commands that control
your remote controllable components. The RVL-6 is equipped with two types of flasher outputs, a DEDICATED
FLASHER output and a COMMON FLASHER output. Niles makes two types of IR flashers; the IRC-1 Flooding Flasher
and the IRC-2 MicroFlasher™
.
DEDICATED FLASHER Output
• The DEDICATED FLASHER output is an outlet for IR commands received from any of the RVL-6’s SENSOR
inputs, built-in IR sensor, and the IR DATA IN used generally for control of a receiver or pre-amp (see
Figure 12).

• DIP switches on the rear panel of the RVL-6 enable the blocking of an IR command received from the
RVL-6’s IR DATA IN (for more information see Setting the MODE DIP switches on pages 16 and 17). The
RVL-6’s built in IR sensor can be disabled (for more information see page 18).
COMMON FLASHER Output
• The COMMON FLASHER output is an outlet for IR commands received from any of the RVL-6’s SENSOR
inputs, built-in IR sensor, and the IR DATA IN used for source control (see Figure 12).
• None of the IR commands received via the RVL-6’s sensor inputs or DATA IN can be blocked. The RVL-6’s
built-in IR sensor can be disabled (for more information see page 18).
Recommended IR Flasher Cable
• Niles infrared flashers come supplied with a ten foot two-conductor 22 gauge cable.
• To extend the flasher cable, use un-shielded, two-conductor 16 gauge cable (“zip-cord”). Flasher cable can
be extended up to 200 feet.
Making the IR Flasher Connections
• CAUTION: Power to the RVL-6 and amplifier must be disconnected.
• For your convenience, all FLASHER output connectors on the RVL-6 are removable.
• Observe proper polarity when connecting or extending the IR flasher wire (see Figure 13).
• Strip 3/8” of insulation from the end of each wire.
• Tightly twist each wire end until there are no frayed ends.
• Insert each wire into the appropriate hole on the connector terminals following the IR flasher wire conven-
tion (see Figure 13).
• Tighten the screws which lock the wire into place. Be certain that the polarity labels on the rear of the RVL-6
are precisely followed.

Connecting Multiple Flashers to a Single Flasher Output
• Using crimp caps, wire nuts or solder, connect the negative of one flasher to
the positive of the next flasher (see Figure 14). This creates a “series” circuit.
The IRC-1 Flooding IR Flasher allows a maximum of two in series to be con-
nected to a single FLASHER output. The IRC-2 MicroFlasher allows a maxi-
mum of four in series to be connected to a single FLASHER output.
Automating Your System Using the CONTROL OUT
• The CONTROL OUT supplies a constant 12V DC (maximum of a 200mA draw ) when any of the room
modules are on (see Figure 15).
• When all the room modules are turned off the 12V DC is turned off after a 30 second delay.
Distributing System-Wide Commands Using the UART Connector
• The UART connector distributes the ALLON and ALLOFF com-
mands to all RVL-6’s in the system by connecting in parallel
using two-conductor 20 gauge cable (see Figure 16). Connect
pin one to pin one and pin two to pin two. Wiring runs should
not exceed three feet in length.
Controlling the RVL-6 with X-10®
• The X-10 input enables the RVL-6 to be controlled by X-10
compatible controllers using your existing AC home wiring.
• A TW-523 X-10 Interface Module (sold separately, Niles
stock# FG00256) is required to interface with the RVL-6.
• See the Setting the X-10 DIP Switches section on page 16 for
details on X-10 control options.
Powering Your RVL-6
• The RVL-6 is powered by plugging the 12V DC, 1.2 amp wall adapter (included) into the POWER jack.

Setting the DIP Switches
Setting the Minimum Impedance The Amplifier Can Safely Drive
Setting the IMPEDANCE DIP switches enables the RVL-6 to constantly monitor which pairs of speakers are playing
and select the minimum impedance the amplifier can safely drive. This feature not only protects the amplifier, but
optimizes the amount of power delivered to each speaker.
Setting the AMP DIP Switches
• The AMP DIP switches identify the minimum impedance an amplifier can safely drive (see Figure 17).
• The amplifier must be capable of safely driving a 4 Ohm load.
Setting the SPEAKER DIP Switches
• The SPEAKER DIP switches identify the impedance of each pair of speakers connected to the RVL-6.
Choose between a 4 Ohm setting and an 8 Ohm setting (see Figure 18).
• If a room has two pairs of speakers connected in parallel the total impedance decreases. For example, two
pairs of 8 Ohm speakers connected in parallel is effectively the same as a single pair of 4 Ohm speakers.

Setting the X-10 Operation Parameters
X-10 can control the RVL-6 over your existing AC home wiring. The X-10 commands are comprised of two basic parts,
the address and the command. The address consists of a house code (A-P) and a unit code (1-16). The command is the
function you wish to execute. For more information see Powerline Carrier Controls on page 33.
• The RVL-6 implements the X-10 protocol by assigning a house code and unit code to Room 1 (see Figure 19).
• After room 1 is assigned either the house code or unit code is incremented and assigned to Room 2, and
then is reincremented and assigned to Room 3, and so on. The increment method is configured using the

ZONE DIP Switches
The ZONE DIP switches enable you to control the routing of the IR commands from the IR DATA IN. Your
two routing options include:
• The left ZONE DIP switch controls the routing of IR DATA IN to the Room 1 control module. In the up
position this routing is enabled and Room 1 can be controlled from the IR DATA IN. In the down position
this routing is disabled and Room 1 cannot be controlled by the IR DATA IN (see Figure 21).
• The right ZONE DIP switch controls the routing of IR DATA IN to the DEDICATED FLASHER output. In
the up position this routing is enabled and the dedicated flasher can be controlled from the IR DATA IN. In
the down position this routing is disabled and the dedicated flasher cannot be controlled by the IR DATA
IN (see Figure 21).
Setting the DEFAULTS DIP Switches
The DEFAULTS DIP switches are used to configure various features of the RVL-6.
Choosing Rooms That Respond To An ALL ON Command
The DIP switches labeled ALL ON enable you to individually configure which rooms will respond to the ALL
ON command (see Figure 22). Each room has a corresponding DIP switch (1-6 starting from the left).
• Setting the ALL ON DIP switch in the up position will enable the corresponding room control module to
respond to an ALL ON command.
• Setting the ALL ON DIP switch in the down position will disable the corresponding room control module
from responding to an ALL ON command.
Setting the Turn-On Volume Level
The DIP switch labeled V enables you configure the volume level when a room is turned on (see Figure 23).
• Setting the V DIP switch in the up position will enable all rooms (only one switch), when turned on, to
automatically revert to its previous volume setting.

• Setting the V DIP switch in the down position will enable a room, when turned on, to automatically play
at 25% of the maximum volume level.
Enabling/Disabling the RVL-6’s Built-In IR Sensor
In some installations, having the built-in IR sensor enabled will cause a feedback loop. The DIP switch
labeled E disables the RVL-6 sensor (see Figure 24).
• Setting the E DIP switch in the up position enables the IR sensor.
• Setting the E DIP switch in the down position disables the IR sensor.
Operating Your RVL-6 System
Controlling The RVL-6 Using Its Front Panel
Turning a Room On and Off
• Press the ROOM SELECT button(s) of the room(s) you wish to control. Its corresponding ROOM LED(s) begins
to blink, indicating the room(s) has been selected and is ready to be controlled.
• Press the ON/OFF button to toggle between the room’s on/off status. This command will affect all rooms that
are selected (blinking). If multiple rooms with varying on/off status are selected, the first room selected will
determine if all selected rooms will toggle on or off.
• When a room is turned on, the ROOM STATUS LED stays on. When a room is turned off the LED turns off.
• When a room is turned on, the initial volume level is determined by the V DIP switch setting on the rear
panel of the RVL-6 (for more information see page 17).
Using the ALL ON Command
• Pressing the ALL ON command will turn on all rooms that have been enabled by the ALL ON DIP switches
on the rear panel of the RVL-6 (for more information see page 17).
• The ALL ON command can be linked to other RVL-6’s via the UART connector to turn on enabled rooms
system-wide (for more information see page 14).
Using the ALL OFF Command
• Pressing the ALL OFF command will turn off all rooms.
• The ALL OFF command can be linked to other RVL-6’s via the UART connector to turn off all rooms system-
wide (for more information see page 14).

Controlling a Room’s Volume
• Press the ROOM SELECT button(s) of the room(s) you wish to control. Its corresponding ROOM LED(s) begins
to blink. This indicates the room(s) has be selected and is ready to be controlled.
• Pressing the VOLUME UP or VOLUME DOWN button adjusts all selected rooms.
• If a selected room is off, pressing the VOLUME UP button will first turn the room on to its lowest volume set-
ting and then incrementally raise the volume.
Controlling The RVL-6 Using IR Commands
• The RVL-6 responds to five Niles IR commands: ON/OFF, VOLUME UP, VOLUME DOWN, ALL ON, and
ALL OFF. The optional Niles HC-2 hand-held remote provides those IR commands, but will not learn any
additional commands. It is ideal for rooms where only basic control is desired.
• An IR command received by one of the six IR SENSOR inputs is routed to its corresponding room control
module. The RVL-6 processes the command and takes the appropriate action.
• If the RVL-6 front-panel IR sensor is enabled, the IR command it receives is routed to the Room 1control mod-
ule. The front panel IR sensor is enabled by the DIP switch labeled E on rear panel of the RVL-6 (see page 18).
USING THE RVL-6 MULTI-ROOM CONTROL SYSTEM WITH A NILES INTELLIPAD IR PROGRAMMABLE KEYPAD
IR Commands
• The Intellipad operates as a wall-mount, learning infrared remote control. IR commands for the RVL-6,
the system’s AM/FM receiver, integrated amplifier or preamplifier, and source components are taught to
the IntelliPad. The IR commands that control the RVL-6 are ROOM ON/OFF, VOLUME UP, VOLUME
DOWN, ALL ON, and ALL OFF.
IntelliPad Power Status and the RVL-6
• Due to the unique way the RVL-6 is designed to work with the IntelliPad’s Power Status feature, the
RVL-6’s ROOM ON/OFF command is taught to the IntelliPad’s Power key on the System page of mem-
ory. The Status Feedback jumper must be set to the Enable position, and the Speaker Mute Relay jumper
set to the Disable position. In a standard IntelliPad/IR repeater system configuration, the IntelliPad keeps
track of the system’s AM/FM receiver, integrated amplifier or preamplifier’s Power On/Off status. When
used with the RVL-6, the IntelliPad’s status LED displays the individual room’s On/Off state for the spe-
cific speaker selection it is controlling. This enables the room to be turned on automatically when any
Source Key on the IntelliPad is pressed. If a room is already on and a Source Key is pressed simply to
change what the user is listening to, the room will not turn off. Pressing the Power button turns the room
on when it’s off and the room off when it’s on.
System Power Management
• The system’s AM/FM receiver, integrated amplifier or preamplifier is turned on and off via the switched
AC outlet of a Niles AC-3, triggered by the RVL-6’s control voltage output (12V). The control voltage out
put activates when the first room is turned on, and deactivates thirty seconds after the last room turns
off. This keeps the system power’s on/off status “in sync” with the RVL-6 room, thereby maintaining
“one touch operation.”
Individual Room Muting
• When using a RVL-6 with an Intellipad, the Speaker Muting Relay on the keypad is not used. Room mut-
ing is accomplished in either of two ways.

Option 1: Programming a sequence consisting of ten RVL-6 VOLUME DOWN commands triggered from the
Mute key on the System page of memory.
• The IntelliPad automatically lowers its individual room’s volume while still allowing the user to change
sources or utilize other keypad functions. Keep in mind that this is not a toggle-type function, volume
can only be restored in the room by pressing and holding the Volume Up key until reaching the desired
volume.
Option 2: Teaching the individual ROOM ON/OFF command to the Mute key on the System page of memory.
• This option gives the user the ability to deactivate the individual room from either the IntelliPad’s Power
key or the Mute key. Please note that this is not a true mute function. If the chosen room is the only
room common to the RVL-6 that is active when this MUTE command is issued, the entire system will
be powered off via the AC-3 as explained above.
Teaching the IR commands of the RVL-6 to an IntelliPad
1. The ROOM ON/OFF command of the RVL-6 is taught to the IntelliPad’s Power key on the System page
of memory.
2. The VOLUME UP and the VOLUME DOWN commands of the RVL-6 are taught to the IntelliPad’s
Volume Up and Volume Down keys on the system page of memory.
3. The ALL OFF command of the RVL-6 is taught to the IntelliPad’s Power key on the Press and Hold page
of memory (this enables the user to turn all rooms off by pressing and holding the power button for more
than one second).
4. The ALL ON command of the RVL-6 is taught to an unused Source Key on the IntelliPad that has been
labeled All On (the labels included with the IntelliPad have All On as one of the preprinted choices).
• Programming instructions for the IntelliPad are located on Page 18 of the IntelliPad Installation and
Operation Guide.
Teaching Learning Remotes and IntelliPads the RVL-6 IR Commands
All IR commands required to control the RVL-6 can be taught to a learning remote control via the the RVL-6’s
teaching IR flasher. This integrates control of your source components with control of your RVL-6.
• Press and hold the Room 6 SELECT button.
• As you hold it down, press the Room 1 SELECT button.
• Release both buttons. All the SELECTLEDs flash in a scrolling pattern indicating that your are in teaching mode.
• Put the learning remote in learning mode and select the button on the remote you wish to teach (follow the
manufacturer’s instructions).
• Place the IR sensor on the learning remote one inch from the teaching IR flasher on the front panel of
the RVL-6 (see Figure 25).
• Press the front panel button corresponding to the command
(ON/OFF, VOLUME UP, VOLUME DOWN, ALL ON, and
ALL OFF) you want to teach.
• Repeat the previous three steps for all of the RVL-6 commands
you wish to teach.
• Upon completion, exit programming mode and return to nor-
mal operating mode by pressing ROOM 6 SELECT button.
All the SELECT LEDs go back to their previous state.
