System 2 - Russound A-Bus

SYSTEM 2
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 world’s oldest architectural speaker company and invented the “in-wall” speaker. All Speakercraft speakers are fully UV treated and come with a lifetime guarantee.
