“GORGEOUS PIECES OF INDUSTRIAL DESIGN …
tube-like smoothness … magnificent, full bodied and with great depth …”
– Roger Kanno, Home Theater & Sound
ANTHEM®STATEMENT A2 |A5 multichannel amplifiers
13

Like their larger and even more powerful siblings,A2 and A5 amplifiers
are muscular in character and musical by nature. They are multi-talented
performers more than capable of supplying the power behind the sonically
demanding aspects of surround-sound home theater, or recreating, with
remarkable finesse and transparency, the ‘immediacy’ of a live music
performance.The secret behind their award-winning performance can be
found in Anthem’s unwavering commitment to state-of-the-art design.
A2 andA5 amplifiers boast: completely modular construction; a four-layer
circuit board topology; mirror-imaged, frequency-response channel
matching; eight bipolar output devices per channel; hand-matched
complementary input devices; massive toroidal power supplies; oversize
convection-cooled aluminum heatsinks; and a no-fuse design strategy.
MULTI-TALENTED PERFORMERS
“… phenomenal … completely transparent in their delivery …
synergy between the Anthem amps and the speakers was incredible
… effortless and very convincing … every nuance is presented
wonderfully—at blistering levels … never showed any signs of
running out of steam …”
– Kris Deering, Secrets of Home Theater and High Fidelity on the A2/A5
“… incredibly versatile and rock solid … I was never even close to
pushing the amp to its limits,while the sound was still clean and
precise … performed flawlessly … amazing clarity and immediacy …
as the bullets seemingly flew around my living room and explosions
were shaking my walls—I was in no danger of running out of gas.”
– Bryan Dailey, AudioVideo Revolution on the A5
“… dead quiet and completely imperturbable … solid as a block of
steel … sound was pure and convincing … everything was rich
and burnished within that deep soundstage … percussive leading
edges and delicate trailing sounds—reproduced beautifully … steady
and unruffled while conveying the full power … a bargain at the
price and highly recommended.”
– Wes Marshall,Home Theater & Sound on the A5
RAVE REVIEWS

“NO FUSE” DESIGN
A2 and A5 amplifiers are Direct-Connected to the power supply capacitor
bank, keeping output impedance remarkably low while making more
power available to the amplifier. Even when the amplifiers are driving
lower- or complex-impedance loads, the result is audibly superior
performance. If an output short circuit does occur, only the AC line
breaker will trip—there are no fuses to replace.
The standby low-power supply is protected by self-resetting Positive
Temperature coefficient thermistors (PTCs). Once the condition that
tripped the PTC disappears, the circuit restores itself automatically.
HAND-MATCHED COMPLEMENTARY INPUT DEVICES
Heat shrink tubing applied around each critical pair of hand-matched
complementary input devices ensures superior thermal tracking and
lower voltage offset and distortion.
OVERSIZE OUTPUT CONNECTIONS
Custom-designed oversize gold-plated binding posts ensure full power
delivery at all times. They’re easy to use while facilitating large speaker
cable connectors.
OVERSIZE CONVECTION-COOLED HEATSINKS/FINS
Computer-designed and modeled to maximize contact area for exceptional
heat transfer, these amplifiers run cooler for greater reliability without
the need for a noise-inducing fan.
MASSIVE OVERSIZE POWER SUPPLY RESERVOIRS
To store all of the energy required for the immense bursts of power
required in movie special effects or the taxing crescendos in music,
large banks of capacitors are required.
A2 and A5 amplifiers employ 16,400 micro farads (µF) of capacitance
per channel. (That’s over 80,000 µf alone in the A5!) With so many
joules of power in reserve, these amplifiers are able to instantly and
effortlessly deliver full, uninterrupted bursts of power.
DESIGNED AND BUILT IN NORTH AMERICA
Heavy-gauge 14-awg steel chassis with fine-grain brushed aluminum
cover and extruded aluminum handles.
Includes IEC detachable AC female sockets and high-power, high-quality
14-awg AC cords.
Can be ordered with rack-mount handles.(See Dealer for more information.)

EIGHT BIPOLAR OUTPUT DEVICES PER CHANNEL
Solid-state amplifiers get their power from the output devices used in
the amplification stage—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 amplifiers run cooler, making
them more reliable. A2 and A5 amplifiers each have eight bipolar
output devices per channel ensuring tremendous current reserves and
outstanding reliability.
FOUR-LAYER CIRCUIT BOARDS
Our hand-designed four-layer military spec (FR-4-rated) glass-epoxy circuit
boards with plated
through-holes makes extensive use of groundplanes
to ensure excellent
separation between amplifier channels.The result is
exceptionally low noise and low crosstalk between channels, as well as
between inputs.This multi-layered design also offers increased protection
from electrostatic discharge.
120 dB SIGNAL-TO-NOISE RATIO
Transformer-induced noise at the bass frequencies of 60 Hz,120 Hz, and
180 Hz has effectively been eliminated.As a result,A2 and A5 amplifiers
boast vanishing noise and remarkably low levels of Total Harmonic
Distortion. The reproduction of subtle harmonic structures in each of
these powerful amplifiers reveals extraordinary spatial ambience and
soundstage dimension.
ULTRA-QUIET TOROIDAL POWER SUPPLY
Thanks to massive conservatively rated toroidal power supplies designed
with high rail voltages,A2 and A5 multichannel amplifiers provide ultra-
quiet performance.Transformers are shaped to minimize stray electro-
magnetic radiation and tuned to minimize hum.
STATE-OF-THE-ART MODULAR DESIGN
A2 and A5 amplifiers reflect the benefit of a common modular design
enhanced by our highly refined amplifier circuit topology. Each amplifier
channel is self-contained on its own board and heatsink. In the rare
event that servicing is required,it can be done quickly and easily by a
qualified technician, minimizing the down time of your system.
REFERENCE-QUALITY INPUT CONNECTION
Gold-plated female RCA jacks on the A2 and A5 provide a high-quality
input connection. True-Balanced XLR connections ensure the lowest
level of noise and hum possible.
Our unique auto-sensing technology means no switches. Just plug in
either the RCA or XLR connector and our auto-sensing technology will
automatically select the right input.
POWER ON/OFF THREE WAYS
A2 and A5 amplifiers can be powered On/Off three ways:
1. Manually, with the On/Off switch on the front panel.
2. Remotely, via the 12-volt trigger input on the rear.
3. 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.

ADVANCED LOAD MONITORING (ALM)
All Anthem®Statement amplifiers are designed to perform flawlessly—offering stunning musicality,
tonal neutrality and incredible dynamics while driving any speaker load reliably under real-world
conditions! The power supply is conservatively rated and the amplifiers run cool for greater
reliability, but we didn’t stop there.
These amplifiers feature our ALM (Advanced Load Monitoring) circuitry which protects
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. Buyer beware however! Not all
amplifier manufacturers have sophisticated load-monitoring provisions. Many have saved the
added cost, leaving their output devices unprotected, choosing instead to use the amplifier’s
output devices as “fuses.” At Anthem, ALM is just one of the ways in which our products
provide owners with years of reliable service.
