Stereo power, digital conversion and ARC Genesis in one amplifier
Anthem STR Integrated Amplifier is a solid-state stereo integrated amplifier rated at 200 W x 2 into 8 ohms, 400 W x 2 into 4 ohms and 550 W x 2 into 2 ohms, with DAC, MM/MC phono and ARC room correction.
STR Integrated combines preamplification, digital conversion, source management and a high-current output stage in the same chassis. Connectivity includes analogue and digital inputs, high-resolution USB, MM/MC phono, IP and RS-232 control, together with a front graphical display and a toroidal transformer for the power supply.
Key features
- Power output of 200 W x 2 into 8 ohms, 400 W x 2 into 4 ohms and 550 W x 2 into 2 ohms.
- Internal DAC with USB input up to 32-bit/384 kHz and DSD 2.8/5.6 MHz.
- Coaxial and optical SPDIF inputs plus balanced XLR AES/EBU input.
- Dedicated phono stage for MM and MC cartridges.
- Anthem Room Correction ARC Genesis room correction.
- Multifunction graphical display on the front panel.
- Control via IP and RS-232.
- Toroidal transformer and Black or Silver finishes.
Power and drive capability
The output stage delivers 200 W per channel into 8 ohms, doubles to 400 W into 4 ohms and reaches 550 W into 2 ohms. This progression shows substantial current reserve for loudspeakers with varying impedance and allows the integrated amplifier to retain control as the load becomes more demanding.
DAC and digital inputs
The internal DAC allows digital sources to connect directly without an external converter. The USB input supports PCM up to 32-bit/384 kHz and DSD 2.8/5.6 MHz, while coaxial SPDIF, optical and balanced AES/EBU inputs broaden compatibility with players, streamers and computers.
MM/MC phono and analogue sources
The integrated phono stage accepts both MM and MC cartridges, allowing a turntable to connect directly without a separate phono preamplifier. The analogue section works alongside digital sources within the same control path, keeping STR Integrated at the centre of a stereo system.
ARC Genesis
ARC Genesis room correction measures system response in the listening environment and applies filters to compensate for the main interactions between loudspeakers and room. In this context ARC means Anthem Room Correction, not HDMI Audio Return Channel, which does not apply to this stereo amplifier.
Display, control and integration
The multifunction graphical display simplifies configuration and makes key operating information easy to read. IP and RS-232 control also allow integration with home automation and advanced installations, while the remote control keeps the main functions available for everyday use.
Power supply and construction
The power supply uses a toroidal transformer and supports an output stage designed to deliver increasing power as impedance falls. STR Integrated is available in Black or Silver finishes, with the same architecture and feature set in both versions.
