T400-4
A 4-channel amplifier with a steadfast focus on sound quality and Class AB operation, achieving up to a 40% reduction in size versus the previous model—and further improvements in usability with DTM and MEHSA3.
【T400-4】Rockford Fosgate Power Series Overview
This is a 4-channel power amplifier from the Power Series, crafted by Rockford engineers who relentlessly pursue sound quality and insist on Class-AB operation. While achieving up to a 40% size reduction compared to the previous models, it also features DTM for real-time temperature management, MEHSA3 with 5x cooling efficiency, and TO-247 MOSFETs with excellent thermal stability. It is designed to deliver high playback accuracy, as demonstrated by a frequency response of ±0.5dB.
