Statement
P2 & P5 – Performance
from the heart
In life we admire “heart.” When we say someone has
heart we mean passion, spirit, fortitude. And we applaud it. While
the amplifier is the brawn behind every successful music and movie
presentation, it is also the heart! Its role is as crucial as that
of the speakers in its ability to render delicate musical detail one
minute and interpret spine-tingling musical crescendos the next. The
most exquisite pieces of music fall flat without clean, quiet power
to sustain them through to their natural, musical ebb. Movie special
effects require an inordinate supply of stable high-current power to
give visceral credibility to the “special” aspect of each
effect! In fact, all truly successful sound reproduction requires “heart.”
Effortless—with the ability to play quiet to loud, without strain.
Exceptionally clean, clear and detailed. P2 and P5 amplifiers respond
with profound equanimity to their role in the highest-quality two-channel
system or demanding 7.1 surround-sound home theater.
The heart of an amplifier rests with its design and it is here that
P2 and P5 amplifiers begin to reveal their high-end lineage. Our commitment
to edge-of-the-art design includes multi-layered hand-designed circuit
boards with thick two-ounce copper traces; rugged, independent power
supplies with tuned toroidal power transformers for each amplifier
channel; fourteen rugged bipolar output devices per channel for an
overdesigned output stage; massive custom-designed, convection-cooled
heatsinks with serrated fins; a “no-fuse” design. And the list goes
on.
P2 and P5 amplifiers are fundamentally more revealing, display unparalleled musical
refinement and deliver unheard-of resolution for both music and movies. They
rival the finest power amplifiers available at any price.

Edge-of-the-Art
Multi-Mono Design: Less Talk, More Power!
By design, P2 and P5 amplifiers are actually powerful independent “monoblock” amplifiers.
Each channel is self-contained on its own glass-epoxy circuit
board and heatsink. Each channel also benefits from its own
independent power supply. Since there is no common audio path
between channels there is a complete absence of crosstalk.
Regardless of whether one channel or all channels are driven,
there is no penalty in performance—even when all channels
are operating at maximum output!
Frequency-response channel matching is superb. The musical
picture is seamless and exquisitely detailed with a multichannel
soundstage that is astonishingly transparent, cohesive and
three dimensional.
In the rare event that servicing is required, the modular design
allows it to be done quickly and easily by an authorized technician. |

Active-Load Cascoded Complementary
Feedback Input Stage
P2 and P5 amplifiers benefit from our proprietary input topology—a
unique departure from the classical differential input stage.
Eight low-noise bipolar input devices, hand-matched for superior
balance, are configured in a complementary active-load cascoded
feedback arrangement. Heat shrink tubing applied around each
critical input pair ensures superior thermal tracking. Designed
to reduce distortion, this arrangement not only ensures exceptionally
linear response but also superior bandwidth and superb reliability. |

Massive Toroidal
Transformers: An Audible Difference!
Conservatively rated, in a low-profile design, these low-impedance
toroidal power supplies—one per amplifier channel—make
no sacrifices when it comes to delivering a continuous supply
of pure, clean low-noise power. They are shaped to minimize
stray magnetic field radiation and tuned to minimize hum. A
sequence-controlled soft turn-on significantly reduces power
line transients and in-rush current during start up, preventing
accidental tripping of circuit breakers. |

Independent Power
Supplies Deliver
Maximum Power and a Whole New Level of Quiet
Due to the high costs involved in incorporating sophisticated
independent power supplies many high-end designs have only
one power supply—unregulated and common to the input/driver
and output stages. The drawbacks to this design are a reduction
in maximum power output and overall efficiency when all channels
are operating. The constant charging and discharging of the
power supply filtering capacitors can introduce noise into
the audio path. Anthem™ Statement designers opted for
a more expensive, but ultimately more effective, cleaner and
quieter power supply design.
Each amplifier channel features two separate and autonomous
power supplies fed from separate transformer windings. A regulated
high-power supply used in the driver stage facilitates an overdesigned
output stage, allowing for highly efficient use of the unregulated
high-power supply. P2 and P5 amplifiers are able to deliver
stable, continuous power at maximum output, regardless of the
number of channels being driven. Even when challenged by the
most demanding musical transients, output remains fluid and
continuous. Dynamic bursts of power called for by explosions
and various taxing special effects in movies are delivered
instantly and effortlessly. While some amplifiers tend to oscillate
when driving lower-impedance loads, the P2 and P5 remain perfectly
stable under all conditions. If pushed into clipping, our proprietary
anti-saturation tracking power supply circuit takes over to
ensure seamless recovery.
Since the use of a regulated power supply in the driver stage
removes any noise emitted by the bridge rectifier (often heard
as an audible hum at 120 Hz and its harmonics), the P2 and
P5 achieve an utterly white noise floor. |

Fourteen Bipolar Output Devices
Per Channel
An amplifier’s ultimate performance for music and movies
is directly related to the the number of high-quality, high-current
devices used in the output stage. The greater the number of
devices employed, the lower the dissipated power on each device
and the more power available for the crescendos in music and
the demanding special effects in movies. While some manufacturers
cut corners to save costs in this area, our designers incorporated
fourteen rugged bipolar output devices per channel for an overdesigned
output stage. This results in tremendous current held in reserve
and unsurpassed amplifier reliability. |

2-oz Copper Traces
on Hand-Designed Circuit Boards
Our two-layer FR-4 glass-epoxy circuit boards feature plated
through-holes and heavy 2-oz thick copper traces to promote
excellent conductivity. Extensive use of power- and groundplanes
ensures exceptionally low noise and increased protection from
stray electromagnetic energy—internally, as well as externally
from other devices. |

Oversize Gold-Plated
Binding Posts
Custom-designed oversize gold-plated Anthem™ Statement
binding posts ensure full power delivery at all times. They
are easy to use and facilitate large speaker cable connectors. |
|
|
| |
Multiple Power On/Off Options
P2 and P5 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 panel; or automatically,
with our patented Auto-On/Off circuit. Auto-On turns the amplifier
on when it senses an input signal on any channel and switches
it off 20 minutes after the input signal ends. |
|

|
“No Fuse” Design
By eliminating fuses in the DC rails, P2 and P5 amplifiers
are Direct-Connected™ to the power supply capacitor bank.
This keeps output impedance remarkably low while making more
power available to the amplifier and ultimately to the speakers.
Even when the amplifiers are driving lower- or complex-impedance
loads, the result is audibly superior sonic performance. If
an output short circuit does occur, only our AC line breaker
will trip—there are no fuses to replace. Not only is
this a function of convenience (lifting the cover to change
a fuse in the mighty P5 could be challenging), it also produces
an advanced circuit board layout and a strong, rugged output
stage.
The standby low-power supply is protected by auto-resetting
Positive Temperature Coefficent thermistors (PTCs). Again,
the inconvenience of replacing fuses is avoided while amplifier
circuitry remains well protected. Once the condition that tripped
the PTC disappears, the circuit automatically restores itself
and the amplifier becomes fully functional again.
Anthem™Statement designers incorporated an AC line breaker
on every channel, positioned where they can be visually monitored
and easily reset by the user. Once again, these amplifiers
reap the benefits of a completely modular design—in the
event of an abnormal condition, if the breaker on one channel
trips the remaining channels will continue to operate normally.
And since the breakers are completely outside of the signal
path they do not compromise sonic integrity. |

RCA
and XLR True-Balanced™ Inputs!
A three-way switch on the amplifiers’ rear panel offers
an RCA input, a professional quality XLR balanced input and
an attenuated XLR balanced connection (for preamplifiers that
require it).
Gold-plated female RCA jacks and gold-plated XLR balanced connections
provide the highest-quality input connections. Our fully buffered,
double-balanced-XLR input stage (True-Balanced™) ensures
the lowest level of noise and hum possible. |

Oversize Aluminum Heatsinks
With more than 1,125 square inches (7,258 cm2) of computer-modeled
heatsink (including large serrated fins) per channel, P2 and
P5 amplifiers are superbly equipped to dissipate the heat generated
by their high power levels quickly and efficiently. This, in
turn, eliminates the need for noise-inducing cooling fans.
A thermal sensor on each individual heatsink continuously monitors
safe operating temperature. |

Designed and Built
in North America
Fine-grain brushed aluminum cover and extruded aluminum handles.
Heavy-gauge, low-resonance 12-awg steel chassis and oversize
aluminum heatsinks generate serious high-end weight and authority.
Superior-quality Blue LEDs add an elegant finishing touch to
the high-end demeanour of these multichannel amplifiers.
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, P2 and
P5 amplifiers further demonstrate their high-end pedigree.
The P2 and P5 can also be ordered with optional rack-mount
handles. See your Anthem™ Statement Dealer for more information. |

Advanced
Load Monitoring (ALM™)
Anthem™ Statement P2 and P5 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/Sonic Frontiers, ALM™ is just one of the ways
in which our products provide owners with years of reliable
service. |
