Dedicated LCR Home Cinema Power & Uncompromising Headroom | Available at Trimira Audio
Designed and manufactured in Canada, the Anthem MCA 325 Gen 2 Power Amplifier provides dedicated 3-channel Class AB amplification engineered specifically to drive the front Left, Centre, and Right (LCR) channels in high-performance surround sound cinemas. Delivering 225 Watts continuous per channel into 8 Ohms (400 Watts into 4 Ohms and 600 Watts into 2 Ohms) across all three channels simultaneously, the MCA 325 Gen 2 ensures movie dialogue, musical scores, and dynamic effects are reproduced with real-world impact and zero thermal strain.
The Gen 2 evolution features a redesigned internal circuit layout that significantly reduces internal wiring to provide a shorter signal path, minimizing noise and crosstalk. Driven by a high-power, low-flux toroidal power supply paired with 8 high-current bipolar output devices per channel, the MCA 325 Gen 2 achieves a 120 dB signal-to-noise ratio for a virtually silent noise floor. To ensure long-term stability under heavy operational loads, Anthem’s non-invasive Advanced Load Monitoring (ALM™) system continuously tracks temperature, voltage, and current without placing dynamic-limiting fuses in the audio signal path.
Key Features & Technological Innovations
-
Dedicated 3-Channel Architecture: Tailored to anchor the front soundstage (Left, Centre, Right), providing identical high-current power and tonal matching across all main screen channels.
-
High-Current Bipolar Output Devices: Employs 8 discrete output transistors per channel to distribute electrical load evenly, reducing distortion and enhancing heat dissipation.
-
Low-Flux Toroidal Power Supply: Heavy-duty custom toroidal transformer eliminates stray magnetic fields, keeping internal noise floors exceptionally low.
-
Advanced Load Monitoring (ALM™): Microprocessor-driven thermal and current monitoring guards against short circuits and over-current conditions without fuses in the signal path.
-
Streamlined Low-Cabling Topology: Optimized internal structure increases power bandwidth (-3 dB at 90 kHz) and delivers a fast 30 V/µs slew rate for immediate transient response.
-
Balanced & Unbalanced Inputs: Individual gold-plated single-ended RCA and balanced XLR inputs for all 3 channels provide easy integration with Anthem AVM processors or external preamplifiers.
-
Versatile System Management: Includes 3-way turn-on modes (manual control, 12V DC trigger, or auto-sensing signal input) and an energy-efficient low-power standby mode (<2W).
