Overview

Our take on the Anthem MCA 325

Three-channel power amplifiers like Anthem's MCA 325 are designed to drive the front left, center, and right speakers in a surround sound system. The beefy MCA 325 will drive even power-hungry speakers to movie theater volume levels without breaking a sweat. And this well-engineered amp excels at controlling the stop-start motion of your speakers' drivers, enhancing virtually every aspect of sound quality from deep bass, to dynamics, to soundstaging.

A bigger, clearer front soundstage for your home theater

Three-channel power amplifiers like Anthem's MCA 325 are designed to drive the front left, center, and right speakers in a surround sound system. The beefy MCA 325 will drive even power-hungry speakers to movie theater volume levels without breaking a sweat. And this well-engineered amp excels at controlling the stop-start motion of your speakers' drivers, enhancing virtually every aspect of sound quality from deep bass, to dynamics, to soundstaging.

Usually, 3-channel amps like the MCA 325 are paired with A/V preamp/processors like Anthem's superb AVM 60. But if your home theater receiver has preamp outputs — and many do, like Anthem's MRX Series models — you can easily connect the MCA 325 and use it to drive your front left, center and right channels. That surge of added power brings startling impact to movie soundtracks.

Inside the Anthem sound

Anthem MCA 325 back panel

The MCA 325 has RCA and XLR inputs for use with a wide range of A/V preamp/processors.

The MCA 325's rated power output provides a clue to this amp's unshakeable grip on the music. It produces 225 watts per channel at 8 ohms, 400 watts into 4 ohms and an incredible 600 watts into 2 ohms!

Those numbers tell you that the MCA 325 has a very robust regulated power supply. And each channel has eight bipolar output transistors, to deliver loads of effortless high-current power. The typical A/V receiver uses only two output transistors per channel.

When designing their latest MCA Series amplifiers, Anthem upgraded nearly every part in the signal path in order to reduce noise and distortion. From the custom high-power toroidal transformer inside, to the re-designed speaker binding posts in back, every feature was optimized so that you'll hear clean, transparent sound emerging from an eerily quiet background.

Anthem MCA 325

Crutchfield Customer Review (What's this?)

This being my first power amp, I have no experience to compare with & it didn't replace an existing amp. I chose it for the 3 channel aspect and it is doing a solid job. It is paired with my Denon 4300 along with B&W towers and center. While the Denon takes care of six B&W M1 speakers doing the surround work, that Anthem handles the bigger speakers. It was easy to set up and has a solid (heavy) build. It kicks in when needed and really makes my towers and center shine. I immediately noticed I was giving less volume (by around 10 points or more) during movies. Taking some load off the Denon allows it to give more to the M1s than it had been. The Anthem may lack some bells and whistles of other amps but it is a real workhorse and I would definitely recommend it if you're looking for a solid three channel amp.

Pros: Solid quality and performance.

Cons: I get some power bleed off when it shuts down which causes a chirp from my tower. Crutchfield rep said that was normal (?)

Features

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.

Note: The MCA series amplifiers are perfectly matched for Anthem's AVM 60 Pre-Amplifier (973AVM60, sold separately).

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.

3-Channel Power Amp: The Anthem MCA 325 is a 3-channel power amplifier. This 3-channel power amp is incredibly stable into difficult, low-impedance speaker loads, making it a reliable performer in even the toughest circumstances. The MCA 325 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 325 amplifier is equipped with three balanced XLR inputs and three unbalanced RCA inputs for Left, Right, & Center channels. 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: Three pair of speaker terminals are provided for connecting a pair of speakers and a center-channel speaker. These 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 325 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.
