The P6 is thus transparent to the Left, Right and Subwoofer(s) outputs from your surround sound processor or receiver and passes them on to your amplifier(s) and Subwoofer(s). The two unbalanced and one balanced subwoofer outputs all carry the same mono signal. You can select whether the mono signal is full range or crossed over according to the frequency you select for the Low Pass crossover. Ready for today's hi-res digital music files and excelling with vinyl playback, too, the P 6 packs an advanced ESS Sabre32 Reference DAC to decode a wide range of digital music files via its digital inputs. ,qwurgxfwlrq 7kdqn
