IR IN Terminal: One three-position plug-in terminal connects
to the included KP21/IR pigtail connector for connection of an
external IR sensor. Provides line-of-sight control from an IR remote
when the KP21 is positioned behind the user’s seating location.
AVH Hub Terminal: One RJ45 jack connects to a KP21 Keypad
Terminal
on an AVH21 A/V hub. This connection provides
two-way communication between the keypad and AVH21 hub
for zone/system control. It also receives digital audio data at
the keypad from the AVH21 for audio from common-source
components, as selected by the zone keypad or a local IR remote.
Speaker Terminal: One four-position screw terminal provides
connection to local zone speakers.
Keypad Address DIP Switch (side): One six-position DIP
switch allows configuration of a unique keypad address (zone
number) for up to 20 KP21’s in a single system.
Zone Right Channel Preamp Output: One two-position screw
terminal for connection of the keypad’s right channel, line-level
audio output to a local high-power amplifier, surround receiver or
subwoofer.
Zone Left Channel Preamp Output: One two-position screw
terminal for connection of the keypad’s left channel, line-level
audio output, to a local high-power amplifier, surround receiver
or subwoofer.
Zone/Keypad Amplifier: The 50-watt-per-channel digital
amplifier provides clean, high-power audio of a selected source
to connected zone speakers by reducing the distance from the
amplifier to the speakers.
Local Source Right Channel Input: One two-position screw
terminal, for connection of the right channel, line-level audio
output from a local source such as a DVD/CD player, MP3 player,
local TV or a video game. This allows the local-source audio to
be played through the KP21 amplifier and zone speakers.
Local Source Left Channel Input: One two-position screw
terminal, for connection of the left channel, line-level audio signal
from a local source such as a DVD/CD player, MP3 player, local TV
or a video game. This allows the local-source audio to be played
through the KP21 amplifier and zone speakers.
Power Terminal: One four-position screw terminal connects a
specific KP21
Keypad Power Terminal on an associated WPS21
power hub to provide power to the KP21 keypad and amplifier.
Keypad Bezel: Snap-on cover for KP21.
KP21 Rear-Panel Features
The SPF (Source Power Flag) is used in conjunction with the
REMOTE CONTROL SETUP/ON-OFF COMMAND configurations
to keep common sources in sync with system ON/OFF Status. The
SPF is an active device that can sense the presence of composite
video or coaxial digital audio from a common-source component.
When no signal is detected, the source is off and the SPF is waiting
for a change of status. When a composite video or coaxial digital
audio signal is detected, the SPF sends a 12V control voltage to
an
AVR21EN SPF Flag-In to let the AVR know the component
is on.
When the AVR21EN is in “Standby” and receives the power On
command, one of the turn-on routines that the AVR runs through
is to power up the common-source components. There is a table in
the AVR’s operating system that is configured with the
REMOTE
CONTROL SETUP/ON-OFF COMMAND settings that gives the
AVR three options for turning source components On.
SPF: When a given source is set to have its On/Off status
referenced by SPF, at turn-on the AVR will “look” at the
Flag-In
Jack
for that component to see whether the 12V control volt-
age is present. If not (and it shouldn’t be), the AVR will output the
power command for that source through the appropriate
IR Emitter
Control Out
. The device will turn On.
DON’T SEND: When a given source is set to DON’T SEND, the AVR
will never send power commands to that device. This device is one
that either is left on all the time (cable box or satellite receiver) or
is, for whatever reason, turned on and off manually.
SEND: When a given source is set to SEND, the AVR will always
send a power command when it is turned On. This is the option to
use when discrete IR On/Off commands are available for a particular
component.
NOTE 1: The AVR runs the same routine in reverse when the AVR
OFF command is received. If in SPF Mode, the AVR will look for 12V
on a
Flag-In Jack . If 12V is present, the power command for
that device will be sent. If in DON’T SEND, no command will be
sent for that device, and if a source is configured for SEND – a
power command – typically an Off command will be sent.
NOTE 2: If a source has somehow turned off, and is being sensed
via SPF, if a source function command is sent from a keypad or
remote (DVD play, etc.), the AVR and SPF will “see” the function
command and know that the source is off and then turn the
source on automatically.
