Anthem P2 2 x 325 Watt Power Amplifier
2-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.
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.
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.
Massive Toroidal Transformers
"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.
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.
