Niles Audio MSA-10A

The MSA-10A allows you to connect up to ten pairs of speakers to your stereo receiver or amplifier and play any or all pairs simultaneously. You don’t have to worry about overloading your amplifier. The MSA-10A uses a special autoformer matching system that keeps your amplifier running safely – even if you have all ten pairs of speakers playing at the same time. The autoformers maintain a nominal 8 ohm load on the amplifier, making it safe for use with most quality amplifiers. Each of the ten speaker pairs can have a nominal impedance of anywhere between 4 and 16 ohms. Isolated left and right channel ground returns make the MSA-10A compatible with all types of amplifiers including those with “isolated” or “floating” output grounds. The removable rear panel connector blocks accept speaker wire up to 14 gauge in size.
