difference in volume between other sources and the DA11, it is probably better to lower the
VOLUME setting of the DA11 below the absolute maximum level if it is much louder than other
sources. It will probably take some experimenting with different music program to establish a
good “working volume” with your system. There is a possibility that the optimum DA11 level
setting will still result in the DA11 being slightly louder than other sources. It is also recommended
that you not exceed the absolute maximum level, even with music program that has large
variations in level, because a loud peak could occur that would cause distortion.
In most cases, lowering the volume setting on the DA11 will degrade the signal quality less than
lowering the volume control on the receiver below a setting
which is “normal” for other analog
sources (phono, FM broadcast, etc.). The digitally controlled analog level circuitry of the DA11
degrades the signal less than typical “knob” potentiometer volume controls on consumer
equipment, particularly at lower level settings.
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 closest DA11
Volume control setting t
hat 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.”
If you have difficulty determining the correct setting, please contact
once you have the manufacturer’s ratings for your
equipment.
