Optimizing the Output Level
Best performance is obtained when operating the Wadia Volume Control near the top of its range. If needed, the
maximum output level of your Wadia 381/381i CD Player can be adjusted to match the overall sensitivity of your
system so that the critical listening will take place with the volume control operating near the top of its range.
The maximum output level of the Wadia 381/381i CD Player is adjustable by means of a set of internal switches.
The Wadia 381/381i CD Player is factory set to accommodate the most common range of system sensitivity. If
you find that your typical volume level during critical listening is below 65 on the volume display, it will be
advantageous to use a different setting. To change the output level, consult your dealer.
Connecting to Other Digital Sources (Wadia 381i CD Player only)
The Wadia Integrated CD Player /Decoding Computer is equipped with digital inputs which can accept digital
signals from any of these established digital formats. (Input 1: Wadia USB, Input 2: Coaxial with BNC connector,
Input 3: Plastic-optical TOSLINK, Input 4: AES/EBU with XLR connector).
The Wadia Integrated CD Player /Decoding Computer digital inputs will decode any word length up to 24-bit,
and any of the standard digital audio sampling frequencies up to 96kHz.
Choosing a Digital Cable (Wadia 381i CD Player only)
The performance of any digital transmission method depends on the quality of the cable and the sophistication of
the transmitter and receiver. For example, a high quality coaxial cable can outperform a low quality AES/EBUcable.
A high quality AES/EBU cable will outperform a poorly implemented glass optical system. If you are using a
coaxial cable we recommend that you have the cable terminated with a BNC connector. This will provide higher
performance than an RCA connector. Your Wadia Integrated CD Player /Decoding Computer comes with an
RCA/BNC adapter that can be used for experimentation between different types of coaxial cable. Please note
that USB cables from different manufacturers can exhibit a broad range of performance levels. Regardless of
manufacturer, the length of USB cable can affect sound quality in significant ways, with shorter lengths always
sounding better than extremely long lengths.
Again, we highly recommend that you take advantage of your dealer’s experience and, most importantly,
trust your ears.
All XLR-type inputs and outputs on the Wadia 381/381i CD Player, both digital and analog, use the standard
audio pin configuration:
Pin 1 - Ground
Pin 2 - Positive signal
Pin 3 - Negative signal
