of reflections and the additional acoustic conduction into the board can affect
your monitor's amplitude and phase response. Avoid speaker placement
directly on the console's meter bridge, because this results in two different
acoustic paths between the speakers and the recording engineer causing
undesirable comb filtering effects and poor imaging. The first path is the
direct one, and the second is via a reflection off the mixer main control panel
(as shown in Figure 1 below). Speaker placement directly on the meter
bridge also couples acoustic energy from the speaker's cabinet more readily
into the console's chassis. Both conditions should be reduced by placing the
speakers on their own stands acoustically detached from, and slightly behind,
the console as shown in Figure 2. In this location, the reflective path off the
console's control panel is now blocked by the meter bridge.
