ANTHEM Multichannel Amplifier 2 x 225 Watts

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.

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.

 

 

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.

 

OVERSIZE OUTPUT CONNECTIONS
Custom-designed oversize gold-plated binding posts ensure full power delivery at all times. They’re easy to use while facilitating large speaker cable connectors.

 

 

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.

 

DESIGNED AND BUILT IN NORTH AMERICA
Heavy-gauge 14-awg steel chassis with fine-grain brushed aluminum cover and extruded aluminum handles.
Includes IEC detachable AC female sockets and high-power, high-quality 14-awg AC cords.
Can be orderedwith rack-mount handles. (See Dealer for more information.)

 

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.

 

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 groundplanes 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.

 

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.

 

120 dB SIGNAL-TO-NOISE RATIO
Transformer-induced noise at the bass frequencies of 60 Hz, 120 Hz, and 180 Hz has effectively been eliminated. As a result, A2 and A5 amplifiers boast vanishing noise and remarkably low levels of Total Harmonic Distortion. The reproduction of subtle harmonic structures in each of these powerful amplifiers reveals extraordinary spatial ambience and soundstage dimension.

 

ULTRA-QUIET TOROIDAL POWER SUPPLY
Thanks to massive conservatively rated toroidal power supplies designed with high rail voltages, A2 and A5 multichannel amplifiers provide ultraquiet performance. Transformers are shaped to minimize stray electromagnetic radiation and tuned to minimize hum.

 

 

REFERENCE-QUALITY INPUT CONNECTION
Gold-plated female RCA jacks on the A2 and A5 provide a high-quality input connection. True-Balanced XLR connections ensure the lowest level of noise and hum possible.
Our unique auto-sensing technology means no switches. Just plug in either the RCA or XLR connector and our auto-sensing technology will automatically select the right input.


POWER ON/OFF THREE WAYS
A2 and A5 amplifiers can be powered On/Off three ways:

  1. Manually, with the On/Off switch on the front panel.
  2. Remotely, via the 12-volt trigger input on the rear.
  3. Automatically, with our patented Auto-On/Off circuit—an incoming audio signal immediately switches it on, and approximately 20 minutes after the audio signal ends, it simply switches off.
