  • The MM7055 power amplifier produces 140 watts of high current output from each of its five channels, making it capable of long-term power delivery into low impedance speakers. The MM7055 is ideal for a “5.1” home theater system, whether based on a moderately powered receiver or a surround sound processor. You can also use it to power speakers in different areas of your home; stereo reproduction in two rooms plus a mono channel for secondary areas such as a den or kitchen. For more complex home theater systems, the MM7055 pairs with one or several MM7025s to help create a totally immersive “7.1” or “9.1” audio experience.
