Specifications

RCA Inputs, XLR Balanced Inputs
High quality in! High quality out! Gold-plated female RCA jacks provide a
high-quality input connection, but with MCA amplifiers you get much
more. 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 high-end sound since XLR balanced inputs are
included on all MCA amplifiers.
Our unique auto-sensing circuit makes connecting inputs a snap. Just plug
in either the RCA or XLR connector and our auto-sensing circuit
automatically selects the right input. No switches, no problems, it’s simple.
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.
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.
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 30,000 micro farads (µF) of capacitance per
channel (that’s 150,000 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.
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 after-market 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.
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.
