INTRODUCTION
Thank you for purchasing the Audioaccess W.H.E.N. Whole House Entertainment Network. This
system utilizes the vast technological resources of the Harman International Companies to create
a whole new approach to multi-room audio/video entertainment.
With most whole house systems, Home Theater is a secondary aspect of system design and
application. Typically, whole-house source components can be shared with the home theater, but
properly distributing A/V signals and managing source power can become burdensome in system
design and installation. W.H.E.N. resolves these issues by making the Home Theater the main
room, and component, of the system. The AVR21EN High Performance Audio/Video
Multichannel Processor/Amplifier & Multiroom System Controller is the central component for
both the Home Theater and Multiroom Systems. All Sources shared by the Home Theater and
Whole House systems connect directly to the AVR21EN. Source control and power management
are configured and managed centrally with the AVR21EN.
The AVR21EN features the latest technologies for Home Theater signal processing. All levels of
audio and video signals from line level audio, with composite or ‘S’ video to digital audio and
component video routing in addition to an HDMI output provide seamless switching from any A/V
source to numerous options of speaker configurations and video displays. Additionally, there are
endless options for audio signal processing modes including: Dolby Digital EX, Dolby Pro Logic 2,
Dolby Pro Logic IIx, Dolby Headphone, DTS, DTS Neo 6, Logic 7 and more. A Faroudja DCDi
video up-converter scales all inputs to 1080i via HDMI or component video outputs. The
AVR21EN also incorporates EzSet/EQ Home Theater calibration that automatically sets system
audio output parameters, based upon speaker configuration and room characteristics, creating
the ultimate home theater experience.
The Home Theater is controlled with the full-featured AVR21ENR1 Main Room hand-held remote
control that provides complete control of the Home Theater and provides interfacing with W.H.E.N.
Paging and Door Lock Systems.
The whole-house components include the AVH21 Audio/Video Distribution Hub, KP21 in-wall
keypad/audio amplifier and KP21R Remote Zone hand-held remote control.
The AVH21 A/V Distribution Hubs provide a scalable option for distributing whole house A/V and
control signals. Digital audio and control signals are linked to the AVH21 via an IEEE1394
network connection over CAT5e cable. Composite video signals are fed directly to the AVH21’s
via RG6 coaxial cable. Each hub can distribute the six ‘whole-house’ A/V sources from the
AVR21EN to up to seven remote rooms or ‘zones’. Additionally, up to seven video cameras can
be connected for security surveillance or incorporated with the KP21 Keypad microphones for
whole-house A/V paging and monitoring.
The KP21 Keypads provide simple, intuitive control of remote zone functions including: zone
power, source selection, source control, monitoring, paging and timers. The wall-mount keypads
fit most standard 2-gang new construction and retrofit J-boxes. The 2.5” LCD and 14 function
keys provide menu-driven control and setup functions for simple source, zone and system
operation.
The KP21’s also feature an on-board ultra-efficient 50 Watts per channel stereo digital audio
amplifier. Placing the amplifier in the local room, creates crisp, clear and powerful audio
reproduction by reducing the distance between the amplifier and the local speakers. Each keypad
has a local variable line level output allowing incorporation of local high-power amplifiers or
powered sub-woofers Line level audio from a local source can be run through the keypad
amplifier and zone speakers using the keypad’s stereo line level input. Each keypad features a
built-in microphone for whole-house paging and an IR sensor allowing control from the KP21R
hand-held zone remote control or other properly configured programmable remote. An external IR
sensor can be added to provide additional control flexibility.
The KP21R Hand-Held Zone Remote Control provides easy chair control of zone functions,
common and local source control and paging and door lock control.
