With about 6000 hours of R&D, the RS700 power amplifier is highly innovative and resolutely "hi-fi". It is based on a "double mono" structure driven by a high-performance analog/digital board incorporating a DSP. Its signal processing capabilities are used to drive the power stages (limiting, soft clipping, phase and amplitude correction, etc.) but also and especially to offer advanced coupling of this amplifier with speakers through exclusive processing based, among other things, on our knowledge of electroacoustics and, ultimately, on the exact specifications of our driver units and coupled speakers.
The device's topology, the vast possibilities of programming and digital chaining make the ATOHM RS700 base very versatile. Each unit is fully assembled, wired, controlled, and programmed in our workshops. Depending on the applications, different versions are developed and offered.
The ATOHM RS700 amplifier in this "GT EDITION" is a power unit operating in 4 modes. The first mode (GENERAL mode) allows you to "drive" any type of speakers with power, dynamism, finesse, and precision. The U-GUARD processing limits the power stages just before they saturate and provides a soft clipping. Just like the other three modes, this first setup allows, if needed, to (digitally) filter the speakers with a "high-pass" filter in order to truly relieve them in the bass region and to associate, via the XLR outputs, one or two subwoofers to relieve them in the lower frequency spectrum.
The other three modes (GT1-GT2 and GT3) are specific to each model of our GT SERIES speakers. Amplification and speakers then work in symbiosis. The exclusive X-GUARD, T-GUARD, U-GUARD, and X-TEND processing then come into action, allowing an increase in the performance of our GT SERIES speakers in order to extract their ultimate essence.
