Impedence match allows use of multiple speakers. This in-wall IR sensor is combined with a 72W RMS stereo volume control. Allows you to locally attenuate the speaker signal as well as receive IR commands.
Impedance match allows use of multiple speakers with one amplifier. .
Be sure to get Class 2 or higher speaker wire. Regular speaker wire is unacceptable for in-wall use. The Volume Stabilizer detects fluctuation in audio and video volume level and corrects it before it bothers you. This device will do it for you automatically. To connect more than one set of speakers to an amplifier in parallel, you need to adjust for the impedance drop.
