Anthem P5 5 x 325 Watt Power Amplifier
5-channel power amplifier with 325 watts per channel continuous power into 8 ohms.
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.
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.
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.
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.
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.
RCA and XLR True-Balanced Inputs
A three-way switch on the amplifier’s 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.
Oversize Aluminum Headsinks
With more than 1125 square inches (7258cm2) 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. This, in turn, eliminates the need for noise-inducing cooling fans. A thermal sensor on each heatsink continuously monitors safe operating temperature.
