Specifications

The Wadia 121 Decoding Computer will automatically adjust to the supported

data rate. Supported data rates include 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz,

and 192kHz with up to a 24-bit word length.

◆Connecting through USB

Important information about using a USB connection to play high performance

192kHz files.

To play files using a USB connection from your computer to the Wadia

121Decoding Computer, a specific driver must be installed in your computer.

The driver is already installed on MAC computers (OS 10.6.4 and higher).

Windows PCs require the installation of a specific driver. The set-up program

and driver is on the Wadia thumb drive included with your 121Decoding

Computer (see accessories). The set-up program and driver is also available

on the Wadia web site (www.wadia.com/products/121).

Please read all of the instructions and the information on the Wadia 121Decoding

Computer driver installation web page before installing drivers that match your

specific computer operating system.

The Wadia 121Decoding Computer USB input has the capacity to handle music

files up to 192kHz and 24 bits of resolution. The majority of available music files

are at sample rates of 96kHz or below. Before working with files beyond 96kHz,

please make sure you are comfortable with your system and everything is working

properly with files at 96kHz and below.

◆Input Connections

Connecting to Digital Sources

Avoid allowing static shocks to be applied to the inputs or outputs. To prevent

static shocks, touch any grounded surface, such as the Wadia 121Decoding

Computer chassis, before connecting or removing a cable. It is unlikely that a

static shock will damage the unit, but it may cause the Wadia 121Decoding

Computer circuitry to “lock-up” (see TroubleShooting: Lock-up – page 23).

Inputs and outputs can be safely connected to the Wadia 121Decoding Computer:

1 Before the unit is powered up

2 When the unit is in Mute Mode (see Mute Modes – page 17)

The Wadia 121Decoding Computer has five digital inputs:

AES/EBU with XLR type connector

Coax 1 RCA

Coax 2 BNC

Plastic Optical TOSLINK

USB 2.0

To connect a digital source, install the appropriate digital cable between the digital

output of that source and a digital input of the Wadia 121Decoding Computer.
