Optimizing the Output Level

Connecting Other Digital Sources to your Wadia 861

Choosing a

Digital Cable

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 861 can be adjusted to match the overall sensitivity of your system so that the critical listening will take place with the volume control operating in near the top of its range.

The maximum output level of the Wadia 861 is adjustable by means of a set of internal switches. The Wadia 861 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.

Your Wadia 861 is equipped with digital inputs which can accept digital signals from any of the established digital formats.

Input 1: Glass-fiber optical

Input 2: Coaxial with BNC connector

Input 3: Plastic-optical TOSLINK

Input 4: AES/EBU with XLR connector

The Wadia 861 digital inputs will decode any word length up to 24-bit, and any of the standard digital audio sampling frequencies up to 96kHz.

While the Wadia 861 supports all currently accepted transmission formats for digital audio, we recommend using a high quality glass-fiber cable such as the one available from Wadia. Wadia Digital was the first company to

use glass fiber-optic data transmission in digital audio. We have continually improved this format and believe that it offers the best, most consistent performance of all the available options.

Based on our experience, here is a list of digital interface methods in descending order of performance:

1.Glass optical (as implemented by Wadia)

2.AES/EBU using XLR connector

3.Coaxial cable using BNC connector

4.Coaxial cable using RCA connector

5.TOSLINK plastic-optical cable

The quality of any of these transmission methods 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/EBU cable. 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 861 comes with an RCA/BNC adapter that can be used for experimentation between different types of coaxial cable.

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 861, both digital and analog, use the standard audio pin configuration:

Pin 1 - Ground

Pin 2 - Positive signal Pin 3 - Negative signal
