Anthem MCA 225 Gen 2 Power Amplifier

Reference 2-Channel Power Amplification Meets State-of-the-Art Canadian Engineering

Inspiration drawn from uncompromising cinematic and audiophile performance meets ultra-modern multi-channel audio innovation. The Anthem MCA 225 Gen 2 is a high-performance 2-channel Class AB power amplifier, designed to deliver high-current power for demanding 2-channel stereo systems or to drive the main channels in reference home theater configurations.

Housed in a sleek black chassis featuring a modernized front panel designed to aesthetically match Anthem’s AVM series processors, the MCA 225 Gen 2 pairs refined Canadian craftsmanship with Anthem's most advanced amplifier topology.

Engineering Marvel: Unprecedented Signal Purity, Massive Current Reserves

Don't let its clean exterior deceive you. Under the hood, the MCA 225 Gen 2 features 8 high-current bipolar output devices per channel powered by a custom low-noise, low-flux toroidal transformer. Re-engineered to eliminate excess internal cabling, it provides a direct signal path with an ultra-quiet 120 dB signal-to-noise ratio and exceptional dynamic headroom.

Key Performance & Technological Innovations

2-Channel High-Current Output: Delivers 225 Watts continuous per channel into 8 Ohms, 400 Watts into 4 Ohms, and up to 600 Watts into demanding 2 Ohm loads.

8 Bipolar Devices Per Channel: Spreads thermal and electrical load across multiple devices to drastically reduce stress, yielding lower distortion and improved long-term reliability.

Next-Gen ALM™ (Advanced Load Monitoring): Actively monitors internal temperature, current, and voltage without placing fuses directly in the signal path, keeping your amplifier and speakers protected without altering sound quality.

Massive Low-Flux Toroidal Transformer: Features high rail voltages and minimal stray magnetic field radiation for an ultra-quiet noise floor and rapid transient response.

Seamless Turn-On Modes: Flexible trigger-in/out, signal sensing, or manual power options with eco-friendly 1–2W standby power consumption.

Custom Oversized Binding Posts: Heavy-duty audiophile binding posts ensure maximum contact area and a secure grip on heavy-gauge speaker cables.
