IMD SERIES is a series of professional high-performance power amplifiers featuring a Class TD amplification and a DSP processor of 96 kHz/32-bit that combines IRR and FIR filters to make perfectly smooth phase curves, providing a sound that stands out for its transparency. IMD1624 has an output of 4 x 2200W @ 8-ohm, 4 x 4000W @ 4-ohm and 4 x 4500W @ 2-ohm in stereo mode  and 2 x 9000W @ 4-ohm in bridge mode.

TD Class

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.


IMD Series signal processing system is based on a 4th generation german DSP module that features 96 kHz audio clock frequency and extended network capabilities. Thanks to its on board 2 input channels (analogue + digital) and 4 analogue output channels there is no need for external AD or DA circuits. The module offers outstanding operating and controlling capabilities for large and complex PA systems via NetControl2 software, enabling the remote control of various modules.</
