1.3 RACK-MOUNTING

An optional rack-mount kit is available to custom installers.

INTRODUCTION

2.1 INPUT CONNECTIONS

Balanced XLR connection offers the highest transmission quality, particularly over long

cable lengths, because it rejects noise and hum pickup. If your preampliﬁer does not

have XLR outputs, use the RCA inputs.

Do not use “RCA-compatible” connectors that have a hollow center pin with a hole

at its tip. They can damage the ampliﬁer’s RCA jack internally while being inserted.

2.2 SPEAKER CONNECTIONS

Depending on the level of the input signal, the voltage at the outputs can be high

enough to cause electric shock – be sure that power is turned off when connecting or

disconnecting anything. As well, be sure that the speakers are rated for

use with this ampliﬁer – an overdriven speaker can pose a ﬁre hazard.

Connect the red (+) connection on the speaker to the red (+) binding post

on the ampliﬁer, and the black (–) connection on the speaker to the black

(–) binding post on the ampliﬁer using cable that is insulated to handle

the maximum output of the ampliﬁer. Do not overtighten the binding posts as this may

cause damage. The binding post pair accepts a connection from one speaker.

2.3 ON MODES

With the three-way switch located on the rear panel, you can set the way the ampliﬁer is

turned on and off. To use Trigger-On, connect a standard 3.5mm (1/8”) mono mini plug

cable between the ampliﬁer and the preampliﬁer or control component. Once all other

connections are made, connect the power cord to the ampliﬁer and then the wall outlet.

Manual-On:

When in this position, the ampliﬁer is turned on/off via the power button on the front

panel.

Trigger-On:

This feature allows the ampliﬁer to be turned on or off remotely via the trigger. The

3.5mm (1/8”) mini-jack IN receives power (5-24 volts DC) from an upstream component

or system controller. The same trigger signal can be linked to trigger inputs on other

units through the OUT jack. When using Trigger mode, leave the front power button in

the “on” position.

Auto-On:

This feature also eliminates the need to manually operate the power button. Auto-On

turns the ampliﬁer on when it senses an input signal, and switches off approximately

20 minutes after input signal stops. When using Auto-On mode, leave the front power

button in the “on” position..

CONNECTIONS AND OPERATION

2.4 FRONT PANEL

MCA 525 model shown. MCA 225, MCA 325 models are similar.

Power Button LED

This is blue when the ampliﬁer is operating normally. It also indicates abnormal operation

according to the codes below. In most cases only the abnormal channel is shut down

so the others can keep playing, and it resumes playing automatically once normal

conditions are restored.

Rapid ﬂashing (less than 1 second) - short-circuited channel. Inspect the speaker

cables and connectors and make sure they do not touch other wires or ampliﬁer chassis

or any piece of metal.

Slow ﬂashing (more than 1 second) - thermal protection. Allow ampliﬁer to

cool and ensure that ventilation is adequate. In an over-temperature condition the

temperature must drop before output resumes. This could take several minutes

depending on ambient temperature.

Red LED - total shutdown. This can be caused by a ground fault or DC protection.

Verify whether the cause is in the ampliﬁer by disconnecting all inputs and the power

cord. Reconnect the power cord only and turn on the amp. If the LED is still red, contact

your dealer or Anthem Technical Support. For the MCA 525, the LED will also be red if

either fuse on the rear panel is open.

Rev. 033116

AN ALL-NEW MCA SERIES

What does it take to improve on

perfection? Over 15 years of concentration.

The distillation of endless hours of

fundamental research. The willingness

to rebuild from the ground up. And the

focus on a single goal: Leadership through

innovation and technology.

Introducing the new generation of Anthem

MCA Amplifiers, 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 120

dB, background noise is

practically nonexistent,

leaving you with just

pure natural sound

reproduction.

Higher Power into More

Demanding Loads

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

for the center and surround, the new MCA

525 shares its two power supply between

all channels. The result is full bursts of

power – instantly – without affecting

channel separation.

Next generation Advanced Load

Monitoring™ Technology

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 “Standby” 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. MCA 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.

Rev. 012215

FEATURES

Audiophile Binding Posts

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.

Measured Performance

Like all Anthem products the MCA 525,

MCA 325 and MCA 225, designed and

built in Canada, 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.

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.

Detachable Power Cord

By including IEC detachable AC female

sockets and high-power, high-quality

14-AWG AC cords, MCA amplifiers

further demonstrate their high-end

pedigree.

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 theater and the most complex

and dynamic music recordings.
