Anthem : MCA 225
2-channel power amplifier; 225 watts per channel continuous power into 8 ohms.
Designed to match, engineered for power.
New MCA multi-channel amplifiers are Crafted in Canada and perfectly match the new AVM 60 processor & MRX receivers.
To complement the NEW AVM 60 A/V Processor, Anthem introduces the new MCA 525, 325 and 225 power amplifiers. Available in 5, 3 and 2-channel configurations, these new MCA amplifiers feature more robust and efficient power and heavy-duty reliability. The new MCA Series delivers lower THD (total harmonic distortion) for more clean, pure sound and lower noise for a supremely quiet background.
Like all Anthem products the MCA 525, MCA 325 and MCA 225, designed and Crafted in Canada, are like no other amplifiers in the world: custom low noise high-power toroidal transformers; high-current bipolar output transistors; high-quality filter capacitors; advanced power supply regulators; oversized aluminum heatsinks; custom-designed dual binding posts; and patented auto-on/off circuitry. Superior craftsmanship that is reflected in clean, clear, audiophile-quality sound from top to bottom of the frequency spectrum.
