INVERTING ABSOLUTE PHASE: The Wadia 27i has the ability to invert absolute phase

in the digital domain. Pressing the Phase Invert key on the remote control will cause the Wadia

27i to invert phase; pressing it again will switch the phase back to normal. Whenever the Phase

Invert key on the remote control is pressed, the display will change to the Status Screen, as
shown below. The Status Screen indicates whether the current signal uses pre-emphasis and

whether the phase is normal or inverted.

CHANGING BETWEEN DISPLAY SCREENS: During normal operation, the Wadia 

27i

display will switch between the display screens to show information about which functions
are being accessed. For example, the Balance Screen will be displayed if the balance keys
on the remote control ore pressed.
Pressing the Enter key will advance through the display screens in the following order:

1.

2.
3.
4.
5.
6.
7.

Volume Screen

Brightly-illuminated Volume Screen
Balance Screen
Input Screen
Status Screen

Configuration Screens (18 screens total, see “Configurafion”  for more information)

Back to the Volume Screen

TURNING DISPLAY ON/OFF: By pressing the Display On or Off key, the Wadia 

27i

display can be turned off completely. Several of Wadia’s transports will respond to the same
key, allowing you to control both displays at the same time.

If the display is turned off, it will reappear for five seconds whenever a Wadia 27i function
key on the remote control is pressed.

MUTE MODES: The Wadia 27i Decoding Computer has two Mute Modes that are
automatically engaged under different circumstances.

DSP-SOFTWARE MUTE: When the Mute key is pressed on the remote control, the
Wadia 27i Decoding Computer’s DSP engine transmits a stream of zero signal level
samples to the DAC section, which results in zero output.

OUTPUT-RELAY MUTE: The Wadia 27i Decoding Computer has mute relay connected

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 Wadia 

27i 

Decoding Computer detects AC input level below its minimum

operating range

Each time the Wadia 27i Decoding Computer is powered-up

When the volume control is set to zero AND the Mute key on the remote control

is pressed.

When the Wadia 27i is in either Mute Mode, the Volume Screen will indicate this by
displaying the word, “MUTE.”
