Q I am moving to a new home and plan to transfer my AV receiver and speakers to the new location but don’t want to have to run new wiring. Is there a system available that will let me attach a wireless transmitter to my AV receiver and wireless receivers to my speakers and avoid running wires?—Michael DeWaters / via e-mail

A Yes—but only if your AV receiver has line-level preamp outputs. Products such as Monoprice’s Wireless Speaker transmitter ($89) let you send wireless CD-quality audio signals over the 2.4-gigahertz band. You simply run audio cables to the transmitter’s RCA jack inputs and speaker cables from the wireless receiver’s outputs to your speakers. However, such solutions tend to have limited power output on the wireless receiver end—20 watts per channel with Monoprice’s system, for example—and they’re stereo only. And since the 2.4-GHz band is the same one used for Wi-Fi, you could also run into interference problems.
