NX-Serie Class TD Endstufen
We developed the NX series for customers who appreciate the traditional design of solid-state amplifiers with large transformers. The 3U, 19-inch chassis provides ample space for oversized transformers and capacitors. The illuminated LED rings around the potentiometer indicate the input level of the corresponding input channel. When an input signal is present, the ring glows green. It glows yellow when the input level reaches 0 dB and red to indicate clipping. The NX series' design was uncompromisingly engineered for high performance with a traditional transformer power supply.
