Analogue and digital control with ARC Genesis for advanced stereo systems
Anthem STR Preamplifier is a stereo preamplifier with internal DAC, 32-bit/384 kHz USB, DSD 2.8/5.6 MHz, MM/MC phono, Home Theater By-pass and ARC room correction.
STR Preamplifier concentrates source management, digital conversion and signal processing without including a power-amplifier stage. Digital and analogue inputs, MM/MC phono, Home Theater By-pass, IP and RS-232 control make it suitable for separate stereo systems where the power amplifier can be chosen independently according to the loudspeakers and required output.
Key features
- 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.
- Phono stage for MM and MC cartridges.
- Anthem Room Correction ARC Genesis room correction.
- Home Theater By-pass function.
- Multifunction graphical display on the front panel.
- Control via IP and RS-232.
- Remote control and Black or Silver finishes.
DAC and high resolution
The internal DAC handles high-resolution digital sources and allows direct connection of computers, streamers and players. The USB input supports PCM up to 32-bit/384 kHz and DSD 2.8/5.6 MHz, while coaxial, optical and AES/EBU inputs expand connectivity.
MM and MC phono
The integrated phono stage supports MM and MC cartridges, allowing a turntable to connect directly to the preamplifier. This section complements the line and digital inputs, keeping control of traditional analogue sources and high-resolution digital sources within the same component.
ARC Genesis and system management
ARC Genesis analyses loudspeaker response in the room and applies targeted correction to the main anomalies introduced by the listening environment. In this product ARC means Anthem Room Correction and must not be confused with HDMI Audio Return Channel used on other Anthem components.
Home Theater By-pass
Home Theater By-pass allows STR Preamplifier to be integrated into a system that shares the front loudspeakers with a home cinema installation. The dedicated path separates two-channel listening from multichannel management while preserving an independent stereo chain.
Display and control
The front graphical display makes configuration and operating information accessible without relying on an external device. IP and RS-232 control simplify integration with automation systems, while the remote control manages the main functions during everyday use.
Integration with external power amplifiers
Because it contains no power amplification, STR Preamplifier is designed to drive external power amplifiers selected according to the loudspeakers and system requirements. It is available in Black or Silver and can be paired, among others, with STR Power Amplifier for a fully separate stereo chain.
