It is McIntosh 's all-in-one power amplification solution to power seven channels of an advanced traditional home theater system or one that includes a basic configuration for object-based or 3D surround sound.
In these coordinates, MC257 is a power amplifier that immediately stands out for its new and impressive TripleView analog indicator, which shows in real time the power supplied by its three front channels, while increasing the plastic beauty of the set. To the aforementioned TripleView we must add notable improvements introduced with respect to very high-level multichannel power amplifiers previously marketed by McIntosh , such as a 20% increase in filtering capacity, which results in a substantial increase in the perceived dynamic range. and the response to the lower frequencies of the spectrum.
Additionally, when using only the front left, center and right channels, the power output increases by 25%, going from 200 watts continuous to 250 watts continuous per channel. When using all seven channels, the power available for each channel is 200 watts continuous, providing more than enough muscle to power the most demanding home theater systems.
On the other hand, McIntosh 's exclusive Dynamic Power Manager technology guarantees full delivery of the available power whether the speaker impedance is 8 or 4 ohms, while five Monogrammed Heatsinks heatsinks ensure effective heat evacuation. the excess calories generated by the output transistors.
