Anthem AV STR Integrated - Integrated Amplifier

Description

The STR Integrated Amplifier is Anthem's flagship two-channel component, combining a high-resolution preamp, a high-current amplifier section, and onboard Anthem Room Correction (ARC) in one Canadian-designed and crafted unit. It delivers up to 550W continuous per channel into 2 ohms, with MM/MC phono inputs, asynchronous USB audio up to 32-bit/384kHz and DSD, and flexible bass management for one or two subwoofers.

Features

• High-resolution preamplifier section
• High-current, high-output amplifier section with 8 bipolar output devices per channel, toroidal transformer power supply, and Advanced Load Monitoring (ALM)
• Anthem Room Correction (ARC) for optimized in-room response
• Bass management for two subwoofers, in mono or stereo
• Up-sampling of lower-resolution sources to 32-bit/192kHz
• S/PDIF coaxial and optical, and balanced AES/EBU digital inputs
• Asynchronous USB audio input supporting 32-bit/384kHz PCM and DSD 2.8/5.6MHz
• MM and MC phono, balanced XLR, and single-ended analog inputs
• Analog Direct mode
• Graphic front panel TFT display for setup and navigation
• Controllable via Ethernet, RS-232, or supplied IR remote
• Available in Silver and Black finishes
• Crafted in Canada
