With the exception of added placement convenience, design for single or Multi-Zone distributed Audio systems should follow along the same guidelines as those of a conventional system.
Master Bedroom Suites should have separate Amp/Source capability. Upstairs Recreation rooms can often provide a separate Audio/Video source to power themselves and the Upstairs Bedrooms. In this respect, just think of the Audio Transducer in the same vein as you would a conventional speaker. Amplifiers used in multi-room distribution systems which provide an output of at least 100 watts RMS per zone are more than adequate for such applications. We recommend that ALL rooms have some type of 'at hand' Volume Control capability, either wall mounted or by remote control.
