5. the Wadia 581 output stage is capable of driving both types of outputs simultaneously Why should I bypass the Preamplifier A preamplifier is unnecessary when using your Wadia 581 Disc Player The Wadia 581 Disc Player provides all the necessary control functions of a preamp while the signal is still in the digital domain This avoids the sonic degradation caused by analog circuitry switches and wire The Wadia 581 Disc Player output stage can drive any power amplifier and any interconnects even at very long lengths Does the Wadia Volume Control compromise resolution The Wadia 581 Disc Player uses the latest generation of Wadia s proprietary digital volume control The volume level can be varied in the digital domain by means of mathematical manipulation of the signal eliminating the distortion and noise that are inevitable with even the best analog volume controls While conventional thinking indicates that reducing the volume digitally can sacrifice low level resolution Wadia has created an innovative solution Wadia s patented digital filtering algorithm produces a 24 bit output rather than the 16 bits stored on the CD This high resolution signal is then used in the computations which in turn reduce the volume level This new signal is fed directly to the DAC chips Through this innovative method the Wadia 581 Disc Player main tains high resolution even at the lowest volume control settings Can bypass the Wadia Volume Control Becau
