appearance from to . Click it again to unmute the output signal. When the user
mutes the output signal, the light on the volume control of the PDC will flash to indicate that the
volume has been muted. The volume level can be adjusted with the Master Volume and with the
volume button on the PDC when the output signal is muted. The adjusted volume will take effect
when the output signal is unmuted by the user by pressing the Unmute button.
Note - the PDC will automatically mute if the input is set to digital only and there is no digital
signal. In this case the Mute button also changes in appearance to . However, in this
case clicking on the button will have no effect.
Profile Selection - click on one of the four profile buttons to select the corresponding profile as
stored on the PDC.
Download Button - this downloads the current filters from the PDC onto the Filters tab
of the PDC Control Panel.

The upper drop-down box lets you choose between four options:
• Microphone
• Analog
• Digital
• Auto - in this mode the PDC will switch to the digital source if it is present, otherwise it will
switch to the analog source. Auto only switches between digital and analog. For example,
if you have selected RCA as the digital input (see below), then set the input mode to Auto,
then connected a digital source to the AES/EBU input, the PDC will not switch from digital
RCA to digital XLR. When Microphone is selected as the source, the lower drop-down
box lets you select between available microphone calibration files. When Analog is
selected as the source, the lower drop-down box lets you select between RCA
(unbalanced) and XLR (balanced) inputs. When Digital is selected as the source, the
lower drop-down box lets you select between RCA (S/PDIF) and XLR (AES/EBU) inputs.
The Mono Button sends the same signal (the left input) through both the left and right
output channels. Input Units can be selected when a microphone is the input source.
The two options are dB SPL and dBFS. Mic Settings - Gain can be on or off. With the
gain off (red) a higher voltage input (ie. a higher sound level) can be inputted. Mic
Settings - Phantom. This turns microphone phantom power on (when green) and off (red).
Both the Behringer ECM8000, Earthworks M30 and Earthworks M23 microphones used
in the DEQX Calibration kits require phantom power.

Output Selection has 3 settings (applies only to PDC-2.6 digital out option:
• Analog - the output signal is sent only to the analog outputs
• Digital - the output signal is sent only to the digital outputs if available
• Analog / Digital - the output signal is sent to all outputs Analog Volume control can be
turned on or off (This applies only for the PDC-2.6P model). When Analog Volume is
enabled there is still a certain level of digital attenuation available on the digital outputs
(up to -12dB), which is automatically provided in order to simply avoid clipping. If you
