change to digital-out only you will also have to disable the Analog Volume. By default pre-
amp PDC models with digital output have Analog Volume disabled. Input Level Meter
This shows the instantaneous input level for the left and right channels. As the volume
changes, the peak volume (held for 3 seconds) is shown as a line above the solid level
bar. The peak volume is also reported at the top of the meter, whilst the instantaneous
level is reported at the bottom of the meter. For example, in the figure below the peak left
input level, in the 3 seconds prior to the instant in time that this image was taken, was -
16.5 dBFS. The instantaneous left input level was -22.1 dBFS. Note - the levels shown
give correct readings for sine-waves only. To keep the computation overhead low, they
use a very simple peak-detection algorithm. Output Level Meter The output level
meter's operation is similar to that of the input level meter, except that it shows the output
sent to each of the six outputs, after processing. Thus the output levels are affected by
the input levels and by
• the master volume
• the speaker correction filter
• any crossovers applied in the PDC configuration
• any adjustments in gain (see below) made in the IO Manager
• the room correction filter
• any adjustments in gain made using the parametric equalizer Gain Adjust allows
individual output channels to be adjusted up or down in 0.5 dB increments. This can be
useful for (say) manual matching of subwoofers and speakers. The gain adjustments for
all output channels can be reset to 0 by clicking on the button. The Mute Buttons
allow either input channel and any of the output channels to be muted individually. The
Solo Buttons allow either input channel and any of the output channels to be soloed. The
Polarity Buttons allow the polarity of individual drivers to be swapped. All adjustments
using the Mute, Solo and Polarity buttons can be reset by clicking on the button. Status
Information The IO Manager provides the following status information: Status: Displays
whether the PDC is filtering or measuring. If the word 'filtering' is the color 'yellow', this
indicates unstable parametric EQ. (e.g. a parametric EQ has been applied out of bounds,
like a frequency of 1.1Hz; the offending EQ point will be disabled as a precautionary
measure). If the word 'filtering' is the color 'red', this indicates a 'dropped sample'
condition has occurred Digital In, first window: Whether digital in is On, Off, or Muted
Digital In, second window: Whether the CD being played has de-emphasis or not
Digital In, last window: The sample rate of the received digital signal Digital Out, first
window: Whether the digital out signal is synchronised to the internal clock or an external
clock (this applies only if the PDC has the digital out option) Digital Out, second window:
The sample rate of the output digital signal, or, a message if there is no output digital
