ensure that there are no bit errors in the AES/EBU digital audio
data.
Mounting Considerations
Align the Monitors Correctly
Place the monitors so that their acoustic axes are aimed towards
the listening position (see Figure 3). Vertical placement is prefer-
able, as it minimises acoustical cancellation problems around the
crossover frequency.
Maintain Symmetry
Check that the monitors are placed symmetrically and at an
equal distance from the listening position. If possible, place the
system so that the listening position is on the centerline of the
room and the monitors are placed at an equal distance from the
centerline (See Figure 4).
Figure 3. The location of the acoustic axis is on the cen-
terline of the monitor at the given height “h”. The acoustic
axis of the 8351A and 8260A is located at the center of the
coaxial driver.
Figure 4. Symmetrical layout and keeping the acoustic axis
clear from obstructions minimizes reflection surfaces and
maintains accurate localisation because reflections are sym-
metrical.
