FEATURES:

- Dedicated subwoofer output
- Ultrafast diodes in the rectifier circuit
- Custom-made, oversized power transformer
- 30,000 micro Farads in the power supply filter are providing large reserve of instantaneous power
- Low background noise thanks to the gold-plated printed circuit board (PCB) with dedicated ground, power and signal planes
- Short signal path due to the judicious use of the miniature surface-mount components (SMD technology)
