IMD series

Professional amplifiers

Combining the excellent sound of Class AB and the power efficiency of the Class D amplifiers, TD Class technology allows lightweight amplifiers to deliver powerful and high-quality signal at the same time. In this amplifiers the power supply tracks the audio signal at all frequencies, supplying the required rail voltage while at the same time reserving additional headroom. The superior efficiency reached by TD Class allows greater power density while minimizing cooling requirements, yet sound quality matches the best class AB design.
The latest protection system carries out an advanced analysis of signal level. When transducers operate in the nonlinear domain, either at high excursion, high temperature or high voltage, protection system acts as a smart power regulator to extend the component durability, while maintaining the highest dynamic range.
Inputs are available in analogue and AES , AKM 96 kHz A/D converters at the front-end yield an impressive encoding dynamic of 120 dB. AES/EBU digital inputs operate with sample rate converters from 44.1 kHz to 192 kHz.
