121_Manual_Print_03-12:Layout 1 3/30/12 9:41 AM Page 10 Does the Wadia Volume Control compromise resolution? The Wadia 121Decoding Computer uses the latest generation of Wadia’s proprietary digital volume control. The volume level can be varied in the digital domain by means of mathematical manipulation of the signal, eliminating the distortion and noise that are inevitable with even the best analog volume controls.

Critical listening should be done when the 4th or higher LED is lit. The maximum out level of the Wadia 121Decoding Computer is adjustable by means of a series of IR commands issued from the Wadia remote control.

121_Manual_Print_03-12:Layout 1 3/30/12 9:41 AM Page 16 • Important notice for USA type electrical plugs. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.

121_Manual_Print_03-12:Layout 1 3/30/12 9:41 AM Page 18 Inverting the Phase The Wadia 121Decoding Computer has the ability to invert absolute phase in the digital domain. Pressing the Phase button on the remote control will cause the Wadia 121Decoding Computer to invert phase; pressing it again will switch the phase back to normal. When the phase LED is illuminated phase inverting is activated. Headphone Output The Wadia 121Decoding Computer provides a 1/4” headphone jack on the front of the unit.

121_Manual_Print_03-12:Layout 1 3/30/12 9:41 AM Page 20 Installation Unpacking Use care in unpacking your Wadia 121Decoding Computer. Inspect it for any shipping damage and call your dealer immediately if any is found. Do not plug your Wadia 121Decoding Computer into an AC outlet if you find shipping damage. We advise saving all packing materials so that the unit can be easily and safely shipped if the need arises. Do not tip the unit onto the back panel. This can damage input and/or output connectors.

121_Manual_Print_03-12:Layout 1 3/30/12 9:41 AM Page 28 ◆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).
