Know before you buy
Yes. The amplifier is specifically engineered to remain stable and deliver high power into demanding 4-ohm and 2-ohm loads, making it an excellent choice for complex speaker setups.
While it is designed to cosmetically and sonically complement the Anthem AVM 60 processor and MRX receivers, it is a standard power amplifier and can be used with any pre-amplifier or processor that features RCA or XLR outputs.
ALM technology protects the amplifier from short circuits or overheating by monitoring internal temperature, current, and voltage. Crucially, it does this without sitting in the signal path, so it never compromises your audio quality.
No, the MCA 525 is not bridgeable. It is designed as a dedicated 5-channel amplifier, and attempting to bridge the channels could damage the unit.
By removing output relays from the signal path, the amplifier reduces potential points of failure and minimizes signal degradation. This contributes to the unit's exceptionally low distortion and cleaner, more transparent audio performance.
Yes, the MCA 525 is designed for efficiency and consumes less than 2 watts of power when in standby mode.
