Performance From The Heart – ANTHEM STATEMENT P2
The heart of an amplifier rests with its design and it is here that the Anthem Statement P2 amplifiers reveal their high-end lineage: multi-layered, hand-designed circuit boards with thick copper traces; rugged, independent power supplies with tuned toroidal power transformers for each amplifier channel; fourteen rugged bipolar output devices per channel; custom-designed convection-cooled heatsinks with serrated fins; a “no-fuse” design strategy. And the list goes on.
The most exquisite piece of music falls flat without clean, quiet power to sustain it through to its 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.”
Edge-Of-The-Art Multi-Mono Design
By design, P2 and P5 amplifiers are powerful independent “monoblock” amplifiers. Each channel is self-contained on its own glass-epoxy circuit board and heatsink and benefits from an independent power supply. Since there is no common audio path between channels there is a complete absence of crosstalk.
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.
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 amplifier reliability.
Independent Power Supplies
P Series amplifiers are the cleanest, quietest amplifiers in the industry. Each amplifier channel features two separate and autonomous power supplies fed from separate transformer windings. The amplifiers are thus able to deliver stable, continuous power at maximum output, regardless of the number of channels being driven.
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, the proprietary anti-saturation tracking power supply circuit takes over to ensure a seamless recovery.
Massive Toroidal Transformers
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.
Fourteen Bipolar output Devices Per Channel
An amplifier’s ultimate performance is directly related to the number of high-quality, high-current devices used in the output stage. The greater the number of devices employed per channel, the greater the available power to deliver the crescendos in music and the thunder and explosions in movies. And the greater the amount of current that can be held in reserve.
“No Fuse” Design
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. Even when 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.
Three 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.
– Automatically, with our patented Auto-On/Off circuit. Auto-On turns the amplifier on when it senses an input signal and turns off 20 minutes after the input signal ends.
