SOUND PURITY AND INTEGRITY
Our design for MCA amplifiers follows the “Keep-It-Simple” principle. We utilize the fewest possible number of parts in the signal path to maintain the integrity of sound. All parts are of the highest quality and tolerance. These remarkable amplifiers offer the profound sense of musical purity, transparency and naturalness demanded by the most discerning listener.




 

 

EIGHT OUTPUT DEVICES PER CHANNEL
Solid state amplifiers get their power from the output devices used in the amplification stage. Just like cylinders in a car’s engine, the greater the number of devices per channel, the greater the available high-current power for the crescendos in music, or the thrills, thunder and explosions in movies. Performance is simply more effortless. It also means that the amplifier will run cooler, making it more reliable.




 

 

MIRROR-IMAGED CHANNELS
Frequency response channel-matching in our amplifiers has always been far better than the norm. In fact, MCA amplifiers are virtually mirrorimaged. All amplifier channels offer identical performance. The musical picture is incredibly vivid, seamless, and detailed, with a multichannel soundstage that is exceptionally clear, coherent and three-dimensional.




 

 

MODULAR DESIGN
Each amplifier channel is completely self-contained on its own board and heatsink. In the rare event that service should be required, it can be done quickly and easily by a qualified technician, minimizing the “down time” of your system.

 

 

NO NOISE, LOW DISTORTION
In a rare feat, transformer-induced noise at the bass frequencies of 60 Hz, 120 Hz, and 180 Hz, has effectively been eliminated. MCA amplifiers boast vanishing noise and unbelievably low levels of Total Harmonic Distortion.

 

 

120 dB SIGNAL-TO-NOISE RATIO
Signal-to-noise ratio in MCA amplifiers is 120 dB … a truly remarkable feat! Music and movie soundtracks simply appear out of “dead” silence allowing you to become lost in the emotion of the original performance —the mark (and the end goal) of a truly high-end audio-video component. During even the most tranquil musical passages or dramatically quiet moments in a movie, the background is so ‘black’ that it is audibly gone.




 

 

MASSIVE TOROIDAL POWER SUPPLIES
MCA amplifiers deliver incredible dynamics thanks to massive “audiophileapproved” conservatively rated power supplies designed with high rail voltages. Advanced-generation toroidal power transformers ensure ultraquiet 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.

 

STABLE AS A ROCK
Our amplifiers are incredibly stable into difficult, low-impedance speaker loads, making these superb-sounding dynamos reliable performers in even the toughest circumstances

 

 

 

RCA INPUTS, XLR BALANCED INPUTS
Gold-plated female RCA jacks provide a high-quality input connection. XLR balanced connections are commonly used in professional recording and broadcasting to ensure the lowest level of noise and hum possible. Now you can use this same high-quality connection for reference-quality highend sound since XLR balanced inputs are included on all MCA amplifiers. Our unique auto-sensing technology makes connecting inputs a snap. Plug in either the RCA or XLR connector and the technology automatically selects the right input.





 

50% LARGER POWER SUPPLY RESERVOIRS
More Power! More space to store it! With 225 watts, large banks of capacitors are needed to store all of the energy required for the immense dynamic bursts of various special effects in a movie, or the taxing crescendo of a solo piano. These amplifiers are the most powerful MCA amplifiers yet, employing 16,400 micro farads (μF) of capacitance per channel (that’s over 80,000 μF for the MCA 50). With so many joules of energy in reserve, when called upon, the MCA 20, MCA 30 and MCA 50 are able to deliver full bursts of power instantly and effortlessly.

 

LARGER CUSTOM CHASSIS AND HEATSINKS
A redesigned chassis and large custom heatsinks—33% larger than previous MCA Series amplifiers—ensure that these amplifiers dissipate the heat generated by their higher power levels quickly and efficiently. Our custom heatsinks are computer-designed and modeled to maximize contact area for exceptional heat transfer efficiency. Put simply, they run cooler for greater reliability.





 

 

MULTIPLE POWER SWITCHES
MCA amplifiers can be powered On/Off three ways: manually with the On/Off switch on the front panel; remotely via the 12-volt trigger input on the rear; or automatically, with our patented 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.

 

BETTER OUTPUT CONNECTION
Our 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.

 

 

 

DETACHABLE POWER CORD
While a detachable AC power cord comes in handy when connecting various components, its function is more than one of simple convenience. High-end products typically offer the freedom to use a variety of aftermarket power cords offered by specialty cable manufacturers. By including IEC detachable AC female sockets and high-power, high-quality 14-awg AC cords, MCA amplifiers further demonstrate their high-end pedigree.




 

 

SUPERIOR CRAFTSMANSHIP
Like all Anthem products the MCA 20, MCA 30 and MCA 50, designed and built in North America, are like no other amplifiers in the world: 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. Superior craftsmanship that is reflected in clean, clear, audiophile-quality sound from top to bottom of the frequency spectrum.
