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. All rear-panel connectors are labeled. Input 1 on the 
931 Controller is configured for ClockLink. If you are using a source component 
equipped with ClockLink, such as the Wadia 270 CD transport, connect it to Input 1. 
Non-ClockLink sources should not be connected to ClockLink inputs. For instructions 
to configure any input to turn ClockLink on or off, see Configurations on page 24. 
Level Setting 
The Maximum Output Level can be set to match the sensitivity of your loudspeaker, 
room size, and listening preference. The 921 Mono Decoding Computers come 
shipped from the factory with the output level set at 2 volts RMS. For instruction on 
how to configure the output voltage see Output Level Settings on page 13. 
Operation
The 931 Digital Controller acts as the user-interface for the entire 9 Series Decoding 
Computer system and uses remote commands and operations that are similar to 
other Wadia products. For a full list of instructions, refer to Operations on page 16.
