The digital and analog sections of the DX300MAX are powered separately, with each having an independent charging system. The digital and analog hardware and signal communications, adopt optocouplers and I2C isolators to completely isolate the digital to analog sections from any interference.
- The AMP section is powered by a true +/- 8.4V battery pack. No voltage boost is used, which ensures the highest purity and current output.
- An optimized super class A discrete amp circuit, based on the AMP8 module, which eliminates the switching distortion of transistors, while providing the sound signature of a class A amplifier, that also significantly reduces heat generation, is used.
- The DX300MAX has versatile outputs that incorporate a 4.4mm balanced line out, 4.4mm balanced phone out, and a 3.5mm single ended phone out. The voltage output of the 3.5mm single ended is up to 4.4V RMS, and the balanced phone out is up to 8.8V RMS.
- Electrolytic capacitors are used in the DX300MAX.
- A custom 4-wiper potentiometer that has less than +/-2dB channel tolerance has been selected.
- Dual AK4499EQ DAC Chips are incorporated.
