It is McIntosh 's all-in-one power amplifier solution for powering seven channels of an advanced traditional home theatre system or one that provides a basic setup for object-based surround sound or 3D.
In these coordinates, MC257 is a power amplifier that immediately stands out for its striking new TripleView analogue display, which shows in real time the power supplied by its three front channels, while increasing the plastic beauty of the set. In addition to TripleView, there are notable improvements over the very high-end multi-channel power amplifiers previously marketed by McIntosh, such as a 20% increase in filtering capacity, resulting in a substantial increase in perceived dynamic range and response at the lower frequencies of the spectrum.
Also, when using only the front left, centre and right channels, the output power increases by 25% from 200 watts continuous to 250 watts continuous per channel. When all seven channels are used, the available power for each channel is 200 watts continuous, providing more than enough 'muscle' to power the most demanding home theatre systems.
Furthermore, McIntosh 's unique Dynamic Power Manager technology ensures full delivery of the available power whether the speaker impedance is 8 or 4 ohms, while five Monogrammed Heatsinks ensure effective evacuation of excess calories generated by the output transistors.
