The D-Series amplifier range includes seven different Class-D amplifiers. There are three 4-channel amplifiers with optional built-in DSP and a high power 2-channel non-DSP amplifier. All variants can be ordered with optional Dante Networking - we the separate dante listing.  Both power and processing stages perform to Funktion-One's standards of audio fidelity.


The 4-channel DSP versions each include 8 channels of DSP (four auxiliary outputs). These auxiliary DSP outputs can be connected to other Dante receivers, or analogue audio inputs (non-DSP amplifiers or F132As, for example).

D-Series Dante networks are highly robust, with optional dual redundancy and automatic failsafe to analogue. AudioCore provides remote system control over wired and wireless networks, with a comprehensive preset library for easy system setup and tuning.


All can be ordered with optional Dante Networking. *
