Signal Flow
The previous diagrams help create an accurate
mental image of how the D8B functions. The signal
flow diagram in Figure 1-5 (on the next page) looks
more closely at the actual path the signal takes from
a point of origin to a chosen destination. This is a
simplified flow-diagram designed to provide a "bird's-
eye" view. Follow the signal from left to right. Notice
the first thing the signal encounters, after the analog
inputs (including the analog trim), is the analog-to-
digital converter. The audio remains in the digital
domain from that point until it finally converts back
to analog at the main outputs, bus outputs, and
external aux sends. Simply follow the arrows to
discover the path—you never know where you might
end up. For a more detailed block diagram of the
D8B signal path refer to Figure 1-6.

L/R meters, always displays the currently
selected channel number no matter which Fader
Bank is selected. If an adjustment is required in
the Fat Channel, verify that the channel you
intend to adjust is displayed here.

forget to check the Fader Bank status. However,
once you've adjusted to the layered consoles,
maneuvering throughout the entire console will
become second nature.
