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.
