installation • chapter 2 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. Figure 1 (incorrect) Direct Path Reflection Monitors placed on the console's meter bridge can directly radiate back onto the console control panel causing a strong delayed reflection at the listening position Figure 2 (recommended) Direct Path Direct Path Avoids Console -6"- Minimum Random Reflections Moving the monitors to a position behind the meter bridge causes the bridge to block the offending reflective path 10 Monitor One Mk2 Reference Manual
