381/381i CD Player

Phase Invert

All Wadia Players have the ability to invert absolute phase in the digital domain. Pressing the Phase button on the remote control will cause the Player to invert phase; pressing it again will switch the phase back to normal. If the Player is in Phase Invert mode, this will be indicated on the Input Screen of the display.

Display On/Off

By pressing the Display button, the Player can be turned either on or off. When the display is off, each remote command will cause the display to light up momentarily.

Mute Modes

There are two mute modes that are automatically implemented under certain circumstances.

DSP -Software Mute

When the Mute button is pressed on the remote control, the Player’s DSP engine transmits a stream of zero signal level samples to the DAC section, which results in zero output.

Output Relay Mute

There is a mute relay connection between the positive and negative outputs, when this relay is engaged, it connects the positive output to the negative output, reducing the output to zero. This relay, which produces an audible click when it engages or disengages, is not in the music signal path. The mute relay is engaged:

•When the Player detects AC input level below its minimum operating range.

•Each time the Player’s power switch is turned on.

•When the volume control is set to zero AND the mute button on the remote control is pressed. When the Player is in either Mute Mode, the Volume Screen will indicate this by displaying the word, “MUTE.”

TRACK BACK/FORWARD : Pressing these buttons allows access to the previous or next track on a CD.

SEARCH BACK/FORWARD : Pressing these buttons allows fast reverse or fast forward access through a track. Pressing the PLAY button to resumes normal playback.

STOP : Pressing this button while a CD is playing stops PLAY.

PAUSE : Pressing this button, while a CD is playing, suspends PLAY. Pressing PAUSE again will allow playback to continue.

PLAY : After a CD has been loaded, pressing this button plays the CD beginning with the first track

REPEAT : This button controls two repeat modes: Repeat track and repeat all. Pressing the button once will cause the individual track to repeat. Pressing the button a second time will cause the entire CD to repeat continuously. A third button press returns the system to “no repeat” mode.
