Frequently Asked Questions
Should I use a Balanced or Unbalanced connection?
If your amplifier has a true balanced input, we recommend you use the balanced
analog output from your Wadia 121Decoding Computer. All things being equal,
properly implemented balanced (also called differential) circuitry sounds better
than unbalanced circuitry. The Wadia 121Decoding Computer is a true balanced
design. It generates the inverted signal in the digital domain and all subsequent
processing is done in balanced mode. Your Wadia 121Decoding Computer is
designed to maintain many of the advantages of true balanced design when
using the unbalanced outputs. In addition, the Wadia 121Decoding Computer
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 121Decoding Computer.
The Wadia 121Decoding Computer 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
121Decoding Computer output stage can drive any power amplifier and any
interconnects, even at very long lengths.
Does plugging in headphones turn off the speakers?
Yes, the speakers will be muted and the balance (L/R) centered. When the
headphone jack is removed, the speaker volume and balance settings will return
to the previous setting.
