Anthem P5 Power Amplifier

Anthem P5 Power Amplifier

EDGE-OF-THE-ART MULTI-MONO DESIGN
By design, P2 and P5 amplifiers are powerful independent mono-block amplifiers. Each channel is self-contained on its own glass-epoxy circuit board and heat-sink 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.
Since the use of a regulated power supply in the driver stage removes 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 silent noise floor.

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.
While some manufacturers cut corners to save costs in this area, our designers incorporated fourteen bipolar output devices per channel. This results in tremendous current held in reserve.

HAND-DESIGNED CIRCUIT BOARDS
Our two-layer military-spec (FR-4-rated) glass-epoxy circuit boards feature plated through-holes and 2-ounce copper traces, promoting excellent conductivity.
Extensive use of power and ground-planes ensures exceptionally low noise and increased protection from stray electromagnetic energy— internally as well as externally from other devices.
