About the STR

The Anthem STR Power Amplifier is a high-performance Class AB stereo amplifier designed for demanding audio applications. It delivers 400 watts per channel into 8 ohms with both channels driven, 600 watts per channel into 4 ohms, and up to 800 watts per channel into 2 ohms for short bursts. The amplifier features 16 high-current bipolar output transistors per channel (8 per channel in some descriptions) to ensure ultra-low distortion (0.004% THD) and high current delivery. It uses a toroidal transformer and has a damping factor of 360 (20 Hz – 1 kHz), with a frequency bandwidth extending up to 91 kHz (-3 dB at 400 W into 8 ohms). Input options include balanced XLR and unbalanced RCA connectors with input impedances of 15 kΩ and 10 kΩ respectively. The amplifier weighs approximately 60 pounds (27.3 kg) and measures 6-3/4 inches in height, 17 inches in width, and about 18-1/2 inches in depth. It includes binding post speaker connectors and a removable IEC 2-prong power cord. The STR amplifier is known for its robust build, high output power, and low distortion, making it suitable for high-end home audio systems. It comes with a 5-year parts and labor warranty.
