Anthem STR Silver Stereo Power Amplifier

£5,199.00

Description

The STR Power Amplifier is the beating heart of a world-class 2-channel sound system. It delivers massive power generation, with audiophile-quality output in a smartly designed component.

Designed, engineered, and Crafted in Canada, the STR Power Amplifier delivers 400 Watts/channel into 8 ohms with both channels driven, a massive 600 Watts/channel into 4 ohms (both channels driven) and 800W in 2 ohms, for true no-holds-barred performance. Inside, the STR Power Amplifier uses two colossal transformers and multiple high-current output devices so the most subtle details and dynamic peaks are handled equally well. Outside, its beautifully designed cosmetics, including a 7-inch graphic control display and secure, highly conductive audiophile connectors provide a perfect match to the STR Preamplifier.

Advanced Load Monitoring Technology
Exclusive ALM technology monitors internal temperature, current and voltage to ensure safe and uninterrupted long-term operation. ALM is not in the signal path, so it never gets in the way. Instead, ALM engages instantly, but only in the most extreme circumstances, to protect your amplifier and speakers from damage, while lowering the chance of a line fuse blowing during an over-current condition. The front panel display confirms status at all times.

Soft Turn-On
A sequence-controlled soft turn-on significantly reduces power line transients and in-rush current during start up, thereby preventing accidental tripping of circuit breakers.

Power On/Off Options
In addition to the traditional options for power-on, the STR Power Amplifier allows trigger mode and audio signal sensing to be combined so you would never need to think about turning the amplifier on or off manually. This can be useful when using a preamp with Home Theater Bypass mode together with a surround sound processor in the same system.

Cascoded Feedback

The STR Power Amplifier benefits from Anthem’s proprietary input topology—a unique departure from the classic differential input stage. Eight low-noise bipolar input devices are configured in a complementary active-load cascoded feedback arrangement for reduced distortion, exceptionally linear response and superior bandwidth. Transistors in critical stages are hand-selected and matched for lowest possible distortion.

Toroidal Transformers

Conservatively rated, in a low-profile design shaped to minimise hum, the low-impedance toroidal power transformers — one for each channel — make no sacrifices when it comes to delivering a continuous supply of pure, clean, low noise power. As well, both the power supply impedance and internal cabling inductance are minimised to deliver a clear path for maximum power.

Rock Solid Performance

Anthem amplifiers go where other amplifiers fear to tread, with a well-earned reputation for being incredibly stable under difficult, low-impedance speaker loads. Short path design, superior DAC, and redundant systems (with Advanced Load Monitoring and other exclusive protective technologies) ensure that peaks are surmounted effortlessly, and guarantee a long life of high performance.

Audiophile Binding Posts

Big power demands big connections, their custom-designed oversized five-way binding posts give you the flexibility you need for even large-gauge bare-wire connections. Insulated, non-conductive, colour-coded jackets make easy, fast, and solid connections with no interference or ghosting.

Power On/Off Options

In addition to the traditional options for power-on, the STR Power Amplifier allows trigger mode and audio signal sensing to be combined so you would never need to think about turning the amplifier on or off manually. This can be useful when using a preamp with Home Theatre Bypass mode together with a surround sound processor in the same system.
