Overview

The Telos 4800 mono power amplifier sets a new benchmark for high-performance amplification, delivering extraordinary power with cutting-edge technology. At its core lies Goldmund’s proprietary Telos® amplification technology, a meticulously engineered Class A/B circuit that merges the linearity of analog components with a high-bandwidth architecture. The result? Unparalleled sonic purity with ultra-low distortion and maximum efficiency. Telos amplifiers are designed for absolute speaker control, providing clean power while preserving the integrity of the audio signal. Proper driver control ensures high-fidelity sound reproduction without distortion or unwanted artifacts. This is particularly key in low frequencies, preventing woofer diaphragms from excessive motion and, hence, unwanted vibrations. By enhancing linearity of each amplification stage, Telos® technology virtually eliminates harmonic and intermodulation distortion. A higher-bandwidth circuit reduces group delay distortion, ensuring impeccable timing and sonic coherence.
Goldmund’s advanced circuit architecture separates high and low-current circuits, preventing feedback and interference for pristine audio signal transmission. The integration of Mechanical Grounding™ technology further enhances signal purity by channeling vibrations directly into the ground. The sophisticated output impedance reduction improves micro-dynamics, controls excessive woofer overshot in high-power conditions, and eliminates unnaturally “boomy” bass, guaranteeing absolute sonic transparency.
