System 1 Block Diagram
Block Diagram One describes both direct connection of the PX-600/603 for adding a single
room to a zone and adding multiple rooms to a zone. It also contains examples for determining
how much amplification is necessary in each area.
Zones 1 through 3 have the straight-forward configuration of standard PX-600 systems.
Each uses one stereo pair of the PX-612 amplifier and has independent source and volume
control via a KPS keypad. Each area is an isolated room used for different purposes. While
the library doesn’t necessarily require high levels of amplification, the homeowners have
determined that they will want separate control in that room; the turn-on volume level will
be set low, as music in this space will generally be background sound. The Guest Room will
be a lockout zone, since the homeowners don’t want curious guests to interrupt their control
of source equipment.
In Zone 4, the master bedroom and bath, source control is only necessary in the PX-600 main
room, the bedroom. A KPS keypad will be mounted on the wall within easy IR range of the
bed, so the homeowners can also use an RT-A or URC-8090 remote. Only limited control is
necessary in the master bath, which they have via a KP3. The homeowners have determined
that their preference is to listen to the default source, the tuner, while in the bath, and that it is
not too much effort to go into the bedroom to change sources.
Zone 5, which includes the formal living room, the formal dining room and the reception
foyer, is an open airspace. The foyer is in the center, flanked by the living and dining rooms.
There are large archways defining the rooms, but no doorways to block sound between the
areas. Thus, it makes sense that each area would share a single source so as not to have an
annoying conflict of sound. During social events, the homeowners have determined that
they would like to have low-level music playing in the foyer for warm background sound as
they welcome their guests, as well as low-level background music in the dining room that
won’t interfere with dinnertable conversation. Because the music is used for ambient effect in
these areas, simple on/off and volume control is all that is necessary, and is accomplished via
KP3s conveniently mounted at the entrance to each area. Should source selection become
desirable, especially in the dining room, an RT-A IR remote controller may also be stored in
this area. The living room, being both a larger space and more likely to require higher listening
levels, is the PX-600 main room, while the dining room and foyer are perfect applications for
PX-603 rooms.
Zone 6, the family room, is the heart of the home’s entertainment center. It is a multi-use
room, with the home theater system and source equipment located in an easily accessible
built-in cabinet. The homeowners will access all source components via the wall mounted
KPS or a URC-8090.
