Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.


Construction: The chassis is durable black metal with padded feet.

Speaker Switches: Each set of speaker outputs has an on/off switch (pressed in for on; pressed out for off) so any combination of connected speakers can be played at any given time.

Built-in Impedance Protection: The MSA-10A is equipped with premium quality autoformers to ensure efficient impedance matching without power loss or heat generation. The autoformers maintain a nominal 8 ohm load on the amplifier, even if all ten pairs of speakers are playing at the same time.

Removable Speaker Terminals: There are 10 removable speaker output terminal blocks and one removable speaker input terminal block, each of which can accept up to 14-gauge wire. This makes it easier to wire the speaker selector into your system.

AC Adapter: The speaker selector operates on 16 volts AC power. A separate AC adapter is included.

Labels: Included are 72 pre-printed and 6 blank label stickers for easy identification of the front panel controls.

Power Handling: The MSA-10A can handle an amplifier with an output of 200 watts per channel RMS, and 300 watts per channel peak music power.
