Multi-Talented Performers

Like their larger and even more powerful siblings, A2 and A5 amplifiers are muscular in character and musical by nature. They are multi-talented performers more than capable of supplying the power behind the sonically demanding aspects of surround-sound home theater, or recreating, with remarkable finesse and transparency, the ‘immediacy’ of a live music performance. The secret behind their award-winning performance can be found in Anthem’s unwavering commitment to state-of-the-art design.

A2 and A5 amplifiers boast: completely modular construction; a four-layer circuit board topology; mirror-imaged, frequency-response channel matching; eight bipolar output devices per channel; hand-matched complementary input devices; massive toroidal power supplies; oversize convection-cooled aluminum heatsinks; and a no-fuse design strategy.

No Fuse" Design

A2 and A5 amplifiers are Direct-Connected to the power supply capacitor bank, keeping output impedance remarkably low while making more power available to the amplifier. Even when the amplifiers are 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.

Massive Oversize Power Supply Reservoirs

To store all of the energy required for the immense bursts of power required in movie special effects or the taxing crescendos in music, large banks of capacitors are required.

A2 and A5 amplifiers employ 16,400 micro farads (μF) of capacitance per channel. (That’s over 80,000 μf alone in the A5!) With so many joules of power in reserve, these amplifiers are able to instantly and effortlessly deliver full, uninterrupted bursts of power.

Hand-Matched Complementary Input Devices

Heat shrink tubing applied around each critical pair of hand-matched complementary input devices ensures superior thermal tracking and lower voltage offset and distortion.

Oversize Convection-Cooled Heatsinks/Fins

Computer-designed and modeled to maximize contact area for exceptional heat transfer, these amplifiers run cooler for greater reliability without the need for a noise-inducing fan.

Eight Bipolar Output Devices Per Channel

Solid-state amplifiers get their power from the output devices used in the amplification stage—the greater the number of devices per channel, the greater the available high-current power for the crescendos in music or the thrills, thunder and explosions in movies. Performance is simply more effortless. It also means that the amplifiers run cooler, making them more reliable. A2 and A5 amplifiers each have eight bipolar output devices per channel ensuring tremendous current reserves and outstanding reliability.

State-of-the-Art Modular Design

A2 and A5 amplifiers reflect the benefit of a common modular design enhanced by our highly refined amplifier circuit topology. Each amplifier channel is self-contained on its own board and heatsink. In the rare event that servicing is required, it can be done quickly and easily by a qualified technician, minimizing the down time of your system.

Four-Layer Circuit Boards

Our hand-designed four-layer military spec (FR-4-rated) glass-epoxy circuit boards with plated through-holes makes extensive use of ground planes to ensure excellent separation between amplifier channels. The result is exceptionally low noise and low crosstalk between channels, as well as between inputs. This multi-layered design also offers increased protection from electrostatic discharge.
