Designed to be the nerve center of a very high-performance Hi-Fi system, the STR Preamplifier concentrates Anthem 's know-how in the field of audio signal processing with one of the most significant engineering features of the American firm: the latest generation of the Anthem Room Correction (ARC) room correction system, whose processing power is 50% higher than the immediately previous version.
Thanks to this sophisticated calibration tool, the user can, with the help of a highly intuitive interface, adapt the sound character of their speakers to that of the space where they are going to be installed. The STR Preamplifier includes analog input circuitry and a high-resolution digital section, highlighting the latter the use of high-precision, very low-noise thin film resistors and specific signal processing that combines a 64-bit accumulator and feedback. to preserve the subtlest details of the music.
Another notable quality of the digital section of this preamplifier is that it resamples all incoming “non-Hi-Res” digital signals up to 32 bits/192 kHz, using an antialiasing filter dedicated exclusively to the aforementioned sampling frequency that is completed with resynchronization of the corresponding data.
The STR Preamplifier also includes a customizable bass management scheme for the use of one or two subwoofers, as well as elaborate phono circuitry with separate inputs for moving magnet (MM) and moving coil (MC) cartridges and connectivity that facilitates its integration into custom systems.
