AES/EBU professional analog line levels:
Set to 56 for 24dBu balanced = 34.72V peak to peak = 12.28V rms
Set to 56 for 18dBu un-balanced = 17.36V peak to peak = 6.14V rms
A typical home power amp or powered speaker:
Set to 40 for 8dBu balanced = 5.6V peak to peak = 2V rms
Set to 46 for 8dBu unbalanced = 5.6V peak to peak = 2V rms
Determining the Correct DA11 Volume Setting for other input ratings-
Use the graph (below) to determine the proper maximum Volume control setting of the DA11 for
other voltage values. For Volts rms or Volts p-p, find the voltage on the vertical scale on the right
side of the graph and trace horizontally until it intersects the relevant curve (solid for rms, dotted
for V peak to peak, balanced or unbalanced). At the point where the horizontal line intersects the
curve, trace straight down to the scale on the bottom of the graph to find the closes DA11 Volume
control setting that will be the maximum volume for your equipment’s inputs. Pro users can use
the vertical scale on the left edge of the graph for the same purpose using dBu units.
For example: if you find 2 volts on the right scale, and trace horizontally until it intersects the
dotted “Unbalanced Vrms” curve, then trace down to the bottom scale, it intersects at “46.”
