MCA Series Amplifier: Anthem's MCA series of amplifiers balance the complex dynamics of today's most demanding multi-channel media with the rare finesse required to satisfy the audiophile in you. MCA series amplifiers provide an abundance of conservatively rated power into demanding low-impedance loads with incredible reliability.

Superior Craftsmanship: The Anthem MCA series multi-channel amplifier's superior craftsmanship is reflected in its clean, clear, audiophile-quality sound from top-to-bottom of the frequency spectrum. MCA series multi-channel amplifiers utilize only the highest quality of parts - like 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.

Stereo Power Amp: The Anthem MCA 225 stereo power amplifier is incredibly stable into difficult, low-impedance speaker loads, making it a reliable performer in even the toughest circumstances. The MCA 225 utilizes 8 bipolar output devices per channel for greater high-current power with less stress on the amplifier.

• 8Ω: 225 watts per channel (continuous RMS, 20Hz to 20kHz, <1% THD)
• 4Ω: 400 watts per channel (continuous RMS, 20Hz to 20kHz, <1% THD)
• 2Ω: 600 watts per channel (continuous RMS, 20Hz to 20kHz, <1% THD)

Massive Toroidal Power Supplies: MCA series amplifiers deliver incredible dynamics thanks to massive, conservatively rated power supplies designed with high-rail voltages. Low flux toroidal power transformers ensure ultra quiet performance by minimizing stray magnetic field radiation. This provides the pure, clean, low-noise power that is needed to reproduce the full dynamics of home theater and the most complex and dynamic music recordings.

Direct Path Circuitry: The  MCA series greatly reduces the use of internal cabling for a much smoother circuit path for pure, unobstructed audio performance. Both power supply impedance and internal cabling inductance have been minimized to deliver a direct, clear path for maximum power; even in the most demanding conditions. Consequently, Anthem removed output relays, so the signal path has absolutely no moving parts. All parts, including the eight bipolar output transistors per channel, are run conservatively so they remain within their safe operating range.

Advanced Load Monitoring (ALM) Technology: Anthem's exclusive ALM circuitry protects the amplifier's sensitive output devices by constantly monitoring temperature, current, and voltage to ensure optimum long-term performance. ALM is totally non-invasive; it is not in the signal path and only engages in the most extreme circumstances to protect the amplifier from damage by maintaining the safe operating area of the output devices.

120dB Signal-To-Noise Ratio: With a signal-to-noise ratio of 120dB, background noise is practically nonexistent, leaving you with just pure natural sound reproduction from the MCA series amplifier.

Balanced & Unbalanced Analog Inputs: The Anthem MCA 225 amplifier is equipped with one balanced stereo XLR input and one unbalanced stereo RCA input. Balanced XLR connections offer the highest transmission quality, particularly over long cable lengths, because they reject noise and hum pickup. If your preamplifier does not have XLR outputs, use the RCA inputs.

Custom-Designed Binding-Posts: Custom-designed, oversized robust binding-posts ensure full power delivery at all times. They're easy to use and facilitate large speaker cable connectors, as well a banana plugs (single only).

Trigger Input/Output: The Anthem MCA 225 is equipped with a 12V trigger input (3.5mm) and 12V trigger output (3.5m) to synchronize power on/off with other components that also feature 12V trigger inputs and outputs.

3-Way On/Off: The MCA series amplifier can be powered on or off in three ways - manually with the On/Off switch on the front-panel, remotely via the rear-panel 5V-24V trigger input, or automatically with Anthem's patented Auto-On/Off circuit. Via the Auto-On/Off circuit, an incoming audio signal immediately switches it on; and approximately 20 minutes after the audio signal ends, it simply switches off.

Protection Circuitry: The Anthem MCA series amplifier utilizes a 3-way protection circuit to guard against Short Circuits (Short Circuit protection), Over-Heating (Thermal protection), and Ground Faults (DC protection).

Crafted In Canada: Anthem's MCA series multi-channel amplifiers are designed and crafted in Canada.
