The Audioplex Master Series of selectors incorporates amplifier protection that does not waste amplifier power. All of the total power of your stereo is delivered globally to your multiroom speaker system. MS series selectors allow you to play any or all of your speakers at the same time. Regardless of the size of your system, the MS 6/8/10/12 selectors simply distribute everything your amplifier sends, safely and without loss. As you change the number of rooms/speakers playing, absolutely no change in volume or sound quality occurs. The secret to wastefree power distribution is the Master Series massive trifilar wound autoformers. Autoformers that are capable of distributing a 750 watt musical peak without distortion.

The MS series is designed and engineered to have a ruler-flat frequency response and ultra-low distortion. Audioplex delivers 20 to 20,000 Hz plus or minus .5dB.

Only Audioplex MS series selectors deliver all of your amplifier's power globally. This means that when the entire system is active, the power of your amplifier is perfectly distributed to each speaker. Of course, the system directs exactly the same amount of power to each speaker pair regardless of how many speakers are playing; so there are never any variations of volume when rooms are turned on and off.
