Installation _____________________ This section includes information on how to unpack and position your Wadia 302 CD Player. Unpacking After carefully unpacking your Wadia 302 CD Player, inspect for any shipping damage and call your dealer immediately if any is found. Do not plug your Wadia 302 CD Player into any outlet if you find shipping damage. Please save all packing materials so the unit can be easily and safely shipped if the need arises.
Installing Cone Feet The Wadia 302 CD Player is equipped with three cone feet that screw into inserts in the bottom panel. These feet will improve performance by reducing vibration. If the Wadia 302 CD Player is sitting on a shelf that can be damaged by the sharp feet, place the steel discs under each foot to protect the shelf surface. Choosing a Location for the Wadia 302 CD Player The sound quality of all high-performance digital and analog components can be degraded by vibration.

Connecting to AC Power Check to make sure your Wadia 302 CD Player has been manufactured for operation at your AC line voltage. Attempting to use your Wadia 302 CD Player at any voltage other than that specified on the rear of the unit may cause damage that is not covered by Wadia’s warranty. Using AC Line Conditioners Of the wide range of power line conditioners currently available, some can provide substantial improvement in sound while others actually degrade sonic performance.
Questions about Connecting the Wadia 302 CD Player To help you decide the best way to connect the Wadia 302 CD Player to your system, read the following list of question asked by Wadia owners: Direct-Connect™ or Pre-Amplifier? The Wadia 302 CD Player is designed to produce excellent performance in systems with or without preamplifiers. However, in many systems a preamplifier is unnecessary when using your Wadia 302 CD Player.
Bypassing the Wadia Digital Volume Control Unlike conventional volume controls, there is absolutely no circuitry in the analog signal path of the Wadia Digital Volume Control -- no passive parts, switch contacts, resistors, or even circuit board traces. The Wadia Digital Volume Control operates in the digital domain; it comprises one computer-programming step in the Wadia’s digital filter algorithm.
Adjusting the Maximum Output Voltage The Maximum Output Voltage is the output voltage when the volume control is set to maximum setting (99). The Maximum Output Voltage is factory set to 4.0 V on the balanced output and 2.0 V on the unbalanced output. You can adjust the Maximum Output Voltage on the Wadia 302 CD Player to match your system by setting the two small switches on the rear panel as shown in the table below.
Infrared Input and Pass-through The Wadia 302 CD Player is equipped with a pair of 1/8" mini-plug infrared (IR) pass-through jacks. The IR pass-through jacks can be used with an IR receiver/transmitter system to send remote control commands directly to the Wadia 302 CD Player. This may be useful for example, if the Wadia 302 CD Player is located outside the field of view of your listening position. Optional Digital Inputs Digital inputs are available as an option on the Wadia 302 CD Player.
Choosing a Digital Cable For maximum performance we recommend using an ST glass-optical cable, which can be purchased from your Wadia dealer, for any digital audio connections. Wadia Digital was the first company to use glass fiber-optic data-transmission in digital audio and we believe that it offers the best performance of all the available options. Based on our experience, here is a list of digital interface methods in descending order of performance: 1.

MUTE The Wadia 302 CD Player has two mute modes that are automatically implemented under different circumstances. 1. Software Mute: When the MUTE key is pressed on the remote control, the Wadia 302 CD Player DSP engine transmits a stream of zero signal-level samples to the DAC section, which results in zero output. 2. Relay Mute: The Wadia 302 CD Player has mute relay connected between the positive and negative outputs.

Appendices_____________________ Trouble Shooting If the Wadia 302 CD Player experiences a powerful static shock or sudden AC surge, it is possible to “lock-up” the computer circuitry.
