Wadia 9 Series Decoding Computer System Owner’s Manual Overview This manual covers the installation and operation of the complete 9 Series Decoding Computer system.
Wadia 9 Series Decoding Computer System Owner’s Manual Quick Start Unpacking and Placement Unpack each of the cartons. Check each component for shipping damage and verify that the operating voltage matches your local AC voltage. The 931 controller should be positioned near the source components, the 921 Mono Decoding Computers should be placed near the amplifier or amplifiers. Connections Use the illustrations below and on the following page to connect the 9 Series Decoding Computer System.
Wadia 9 Series Decoding Computer System Owner’s Manual Standard Configuration: Step 1: Connect Data output 1 from the 931 Controller to the data input of the left channel 921 Mono Decoding Computer. Step 2: Connect ClockLink output 3 from the 931 Controller to the ClockLink input of the left channel 921 Mono Decoding Computer. Step 3: Connect Data output 2 from the 931 Controller to the data input of the right channel 921 Mono Decoding Computer.
Wadia 9 Series Decoding Computer System Owner’s Manual 9 Series Decoding Computer System Installation Unpacking the Wadia 931 Digital Controller Carefully unpack your Wadia 931 Digital Controller and the two 921 Mono Decoding computers. Inspect the outside of the chassis for shipping damage. If you find any, report it to your dealer immediately. Do not plug in the Wadia 931 Digital Controller if you see any signs of shipping damage.
Wadia 9 Series Decoding Computer System Owner’s Manual Connecting the 931 to a Digital Source Digital Sources The Wadia 931 Digital Controller has six digital inputs: • • • • 2 2 1 1 glass fiber (ST) - Input 1,2 SPDIF (BNC) – Input 3,4 plastic fiber (TOSLINK) – Input 5 AES/EBU (XLR) – Input 6 Note: Input One is factory-configured for a ClockLink enabled source, such as a Wadia 270 CD Transport. Using a non-ClockLink source connected to a ClockLink input degrades the sonic performance.
Wadia 9 Series Decoding Computer System Owner’s Manual Wadia Digital Sources with ClockLink The Wadia 931 Digital Controller serves as the reference clock for your entire Wadia digital system. The 931 Digital Controller uses a ultra-stable Temperature-Controlled Crystal Oscillator (TCXO) as a master clock and is further enhanced by a superior power supply. The 931 Digital Controller has a ClockLink output for source components, such as a Wadia 270 CD Transport.
Wadia 9 Series Decoding Computer System Owner’s Manual Connecting the 931 and 921 931 Digital Controller Outputs There are nine outputs on the 931 Controller. One is dedicated for ClockLink and can be used to connect to a Clocklink enabled source. All of the other outputs can be configured as either ClockLink or Data outputs. This allows the Wadia 931 Digital Controller to be used in a variety of system configurations. To change the configuration of the outputs, see Configurations on page 24.
Wadia 9 Series Decoding Computer System Owner’s Manual Connecting to 921 Mono Decoding Computers Connect Data output 1 from the 931 Controller to the data input of the left channel 921 Mono Decoding Computer. Connect ClockLink output 3 from the 931 Controller to the ClockLink input of the left channel 921 Mono Decoding Computer. Connect Data output 2 from the 931 Controller to the data input of the right channel 921 Mono Decoding Computer.
Wadia 9 Series Decoding Computer System Owner’s Manual Connecting the 921 to an Amplifier 921 Decoding Computer Outputs The Wadia 921 has 2 outputs: • • Line-level unbalanced analog on RCA Line-level balanced analog on XLR Connecting Directly to an Amplifier We strongly recommend that you connect your Wadia 9 Series Decoding Computer directly to your power amplifier.
Wadia 9 Series Decoding Computer System Owner’s Manual Illuminated Status Indicator There is a multi-colored LED at the base of the front of the 921 Mono Decoding Computer.
Wadia 9 Series Decoding Computer System Owner’s Manual Choosing a Digital Cable While the Wadia 9 Series Decoding Computer system supports all currently accepted transmission formats for digital audio, we recommend using the glass optical cable that is included in your accessory kit. Wadia Digital was the first company to use glass fiber-optic data transmission in digital audio.
Wadia 9 Series Decoding Computer System Owner’s Manual Frequently Asked Questions Should I use a Power Line Conditioner? The Wadia 931 Digital Controller and 921 Mono Decoding Computer are designed to be used without AC power line conditioners. Similarly, Wadia products are designed to achieve outstanding performance with the AC Power cords included with the units. If you wish to experiment, we recommend that you proceed with caution.
Wadia 9 Series Decoding Computer System Owner’s Manual 9 Series Decoding Computer System Operation Once the 931 Digital Controller and 921 Mono Decoding Computers are configured and installed in your system, all operation is done by using the remote control and display screen on the 931 Digital Controller. Front Panel Controls There are five buttons on the front panel of the Wadia 931. During configuration mode, these buttons change functions (see Configuration).
Wadia 9 Series Decoding Computer System Owner’s Manual 931 Remote Control Commands Below is a diagram of the functions for the Wadia 931 remote control. Keys not described below control transport functions on all current Wadia transports and CD players. See your transport or CD player manual for additional instructions. Button Function Mute Mutes output. Balance Left / Increases balance to one channel by 0.2 db, and decreases the other by -0.2 db.
Wadia 9 Series Decoding Computer System Owner’s Manual Operational Screens There are 2 ways to navigate between the Operational Screens. The user can either scroll through them, or access them directly. The user can scroll in a loop through the Operational screens (plus the Enter Configuration Mode screen) by pressing enter, either on the front panel or the remote control. After 10 seconds of no user activity, the display will revert to the main screen.
Wadia 9 Series Decoding Computer System Owner’s Manual Direct Access to Operational Screens Anytime the user presses a command, the display jumps to that screen. Balance Screen Indicates the current right/left channel balance. The balance is adjusted by pressing the right and left balance keys on the remote control. Each time a key is pressed, the volume on that channel is increased by 0.2 on the display (0.1 dB) on that channel, and decreased by 0.2 on the display for the other channel.
Wadia 9 Series Decoding Computer System Owner’s Manual Volume and Input The volume can be controlled between 0 and 100. Each increment of 1 on the display is 0.5 dB, so the attenuation range is from -50 dB at a volume setting of zero, to 0 dB at volume setting of 100. The display jumps to the main screen whenever the volume or input is changed. Mute Mute is engaged by pressing the mute key on the remote control.
Wadia 9 Series Decoding Computer System Owner’s Manual Additional Features Standby The Wadia 9 Series Decoding Computer system can be put into Standby Mode. To enter standby mode, use the volume down button to set the volume to zero. Then press the mute key. In Standby Mode, the power to the output stage is turned off, and the output is muted.
Wadia 9 Series Decoding Computer System Owner’s Manual Configuration Entering Configuration Mode To enter configuration modes, the user uses the enter key on the remote or front panel to scroll through the main screens to reach the “Enter Configuration Mode” screen. Using the Next Input or Previous Input front panel controls, the user selects “Y”, and presses enter.
