SYSTEM PLANNING
The Audioaccess W.H.E.N. System is made up of three main system components, (AVR21EN
Processor/Controller, AVH21 A/V Hub, WPS21 Power Hub) and three user interfaces
(AVR21ENR1 Main Room Remote, KP21 Keypad, KP21R Remote Room Remote). When
designing a whole house system, careful planning must be made to be sure the system has been
designed properly, gets installed and configured properly and most important, works the way the
homeowner wants the system to work.
There are two main sections to be considered when designing and installing a W.H.E.N. System:
the Home Theater, or ‘Main Room’ and the Remote Rooms that will be referred to here as ‘Zones’.
Main Room
The Main Room component in a W.H.E.N. System is the AVR21EN Processor/Controller. At its
core, it is a highly evolved Audio/Video Surround Receiver. All source components that will be
played in the Main and Remote Rooms will be located near and connected to the AVR21EN. The
Home Theater speakers also connect directly to the AVR21EN.
Typically, the AVR21EN and source components would be installed in the Main Room in a wall
unit, an equipment rack or possibly in an equipment closet. Where ever they get installed, always
leave adequate space between components for free airflow to keep components from
overheating. Use cooling fans when necessary if the components are confined to a tight enclosed
area. Always leave extra space for wiring and whenever possible, when working with a
homeowner on new construction, work with the architect to provide space for the W.H.E.N.
system components that has rear access to system connections for installation and service when
necessary. If a rear access is not possible, a pullout equipment rack is recommended to provide
easy access to system connections. (If rack mounting, an optional rack-shelf is available from
Middle Atlantic Products for the AVR21EN.)
Always position components like DVD/CD players, VCRs, iPod interfaces, etc., to provide access
to the user for loading discs, tapes or connecting an iPod or other portable media player.
In some cases the Home Theater components will be at the front of the room near the screen or
video display. In designing the room layout, leave enough space between the system
components and the screen so the components do not distract the eye while theater system is in
play. (The AVR21EN has Front Panel Timeout and Brightness options that allow dimming or
turning off the front panel display.)
Key to designing the Home Theater is knowing how it will be used. What are the homeowners
habits? Are they critical movie buffs that want the full big theater effect or are they just casual
viewers that want something better than just watching TV? Will they be playing CDs or music
from a server frequently in the main room? Knowing this, along with considerations for room
dimensions and layout, will help determine the configuration and placement of the theater
speaker system. The AVR21EN is fully capable of supporting any audio mode from mono to 7.1
Surround. When planning the speaker section of the main room, pull sufficient wire from the
AVR21EN to all appropriate locations for accommodating 5.1 and 7.1 speaker systems, so that
once the walls are sealed, the necessary wires will be in place for upgrading or changing the
speaker configuration at a future date should the homeowner decide to upgrade.
The same considerations should be given to the video section of the Home Theater. The
homeowner may start out with an OK 32” TV, but at some point may want to upgrade to a wall-
mount LCD or plasma display. They may also consider hanging a projector and drop screen once
they get more familiar with the true Home Theater experience. Plan ahead. Have the homeowner
consider these possibilities and suggest they incorporate the additional wiring during construction,
so future upgrades can be accommodated without ripping the room apart.
