Subwoofer connection – a RCA male to two RCA female AudioQuest adapter can be used to provide extra connection to subwoofer.

How?
The Nuforce Icon HDP incorporates a full-speed USB DAC (24bit/96kHz) and full-function S/PDIF D/A converter (24bit/192kHz), plus a headphone-amplifier circuit and preamp output. Supporting digital USB, S/PDIF in coaxial and 3.5mm optical (3.5mm) modes, along with an analog line input, the HDP accommodates all manner of audio devices. The Icon HDP, which has been designed to serve as the heart of a high-performance audio system, competes head-on with DACs and preamps costing several times its price.
