RUSSOUND A-BUS
Our most popular distributed sound system
makes use of the ingenious Russound A-bus system. Traditional
volume control based systems use a single amplifier that is
split amongst half a dozen or more rooms with a volume control
installed in line between the amplifier and the speakers. A-bus
instead puts a tiny, light-switch sized amplifier in each room
that is fed from the Zone 2 output or tape output of your existing
sound system. The use of multiple amplifiers installed in the
wall mounted keypads reduces the signal loss through the speaker
wire and the inherent losses introduced by speaker level volume
controls.
The remarkable A-bus keypad offers a variety
of advantages over traditional volume control based systems.
They are first of all very attractive and intuitive to use
with an LED bar graph showing your system volume and whether
the system is on. The in-room amplifiers are remote controllable,
so rather than having to get out of your seat and cross the
room to turn down the volume when the phone rings, you can
simply turn it down with the supplied remote control. In addition
to controlling the volume in the room, the A-bus keypad also
has remote control pass-through capabilities. This means that
from any room you can control your CD player, satellite receiver
or any other device that works with an infrared remote control.
The A-bus system has additional flexibility
by allowing you to break away from listening to the whole
house sound by installing local input jacks in any room of
your choice. This way, if you wish to connect the output of
your bedroom TV, office computer or a portable MP3 player
in a given room, it is quick and easy and the system will
even switch over for you automatically. We normally provide
one local source input. More can be added of course.
You may choose either in-wall or in-ceiling
speakers manufactured by Speakercraft. Speakercraft is the
worlds oldest architectural speaker company and invented
the in-wall speaker. All Speakercraft speakers
are fully UV treated and come with a lifetime guarantee.
