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. The headphone output is driven by Wadia’s SwiftCurrent Class A

amplification stage. The Wadia remote control volume buttons control headphone
