Description

The STR Power Amplifier is the two-channel powerhouse of Anthem's STR Series, designed, engineered, and crafted in Canada with a proprietary cascoded complementary feedback input stage and sixteen bipolar output devices per channel. It delivers 400W into 8Ω, 600W into 4Ω, and 800W into 2Ω, all continuous with both channels driven, backed by dual massive toroidal transformers and Advanced Load Monitoring (ALM) protection.

Features

400W/600W/800W into 8/4/2 ohms
Cascoded complementary feedback input stage with hand-selected, matched transistors
Sixteen bipolar output devices per channel in Class AB configuration
Dual mono design
Massive toroidal transformers, one per channel
Soft turn-on to reduce power line transients and in-rush current
Four power on/off options, including trigger and audio signal sensing
No rail fuses; amplifier sections direct-connected to the power supply capacitor bank
Advanced Load Monitoring (ALM) technology, not in the signal path
Graphic front panel display for power meter, status, and setup navigation
Custom-designed oversized five-way binding posts, insulated and colour-coded
Available in Silver and Black finishes
Crafted in Canada
