If a red warning light appears, turn the analog source down!
If the levels are already modest and a digital signal is being
used, 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 to-
wards the listening position (see Figure 3). Vertical placement
is preferable, as it minimises acoustical cancellation problems
around the crossover frequency.
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 symmetrical.

the front baffle of free-standing monitors. Correct (green)
and not recommended (red).
