Anthem MCA 525 Power Amplifier is the flagship of the extraordinary MCA range which focuses on a single goal of obtaining leadership through innovation and technology. It is a 5-channel power amplifier using 225 watts per channel of continuous power into 8 ohm and is designed, engineered and manufactured in Canada.

Completely Redesigned

The new MCA series greatly reduces the use of internal cabling for a much smoother circuit path for pure, unobstructed audio performance. The use of low-flux toroidal transformers and improved input transistors provide a greater sense of transparency, even with dynamically complex material.
We’ve also improved other performance benchmarks including power bandwidth and slew rate. With a signal-to-noise ratio of 120dB, background noise is practically non-existent, leaving you with just pure natural sound reproduction.

Anthem MCA 525 – Higher Power

Experience the immense dynamics of up to 600 clean Watts delivered into demanding 2-Ohm loads. Both power supply impedance and internal cabling inductance have been minimized to deliver a clear path for maximum power even in the most demanding conditions.
While previous 5-channel MCA amps used a single power supply for front left and right channels and another power supply of the centre and surround, the new Anthem MCA 525 shares its two power supply between all channels. The result is full bursts of power instantly without affecting channel separation.

Advanced Load Monitoring

Exclusive ALM technology monitors internal temperature, current and voltage to ensure safe and uninterrupted long term operation, all the while eliminating the need for internal fuses. ALM is not in the signal path, so it never gets in the way. Instead, ALM engages instantly, but only in the most extreme circumstances, to protect your amplifier (and speakers) from damage.
This new generation ALM lowers the chance of a line fuse blowing during an over-current condition. Should a fault condition arise, unaffected channels continue to play and all-channel operation resumes automatically once conditions are back to normal. The LED on the front panel confirms status at all times.

Engineered for Reliability

The new generation of MCA Amplifiers uses of Anthem’s years of experience to “engineer out” common amplifier gremlins. Consequently, we’ve 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. Power-on inrush current has been minimized to reduce line disturbances and stress on internal components. We’ve also upgraded internal connectors and increased mechanical strength.

Green Power Consumption

In addition to the reduced inrush current, these new MCA Amplifiers only use between 1-2W in “standby” mode. As with all Anthem amplifiers, they can be switched on manually, via trigger, or by sensing an input signal. New, larger, more conductive audiophile binding posts have been added to maximize contact and maintain a firm grip on the speaker cable.
If you’re in the market for cutting-edge audio component separates, Anthem’s new MCA Amplifiers balance the complex dynamics of today’s most demanding multi-channel media with the rare finesse required to satisfy the audiophile in you. Anthem MCA 525 Amps provide an abundance of conservatively rated power into demanding low impedance loads, incredible reliability, and a new design aesthetic that matches our sleek AVM 60 Pre-Amplifier.

Massive Toroidal Power Supplies

MCA amplifiers deliver incredible dynamics thanks to massive “audiophile approved” 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 theatre and the most complex and dynamic music recordings.

Quality Components

Anthem MCA 525 amplifiers are designed, engineered, and completely Crafted in Canada. We take pride in using only the highest quality components for each one we hand-build. Anthem’s own custom-designed, oversized robust binding posts ensure full power delivery at all times.
They’re easy to use and facilitate large speaker cable connectors. Anthem amplifiers are incredibly stable into difficult, low-impedance speaker loads, making these superb-sounding dynamos reliable performers in even the toughest circumstances.
