Mixing consoles, which are usually of large dimensions, are essential equipment in a mixing room of a production studio. This large obstacle always has to be placed nearby the listening position in a mixing room. A significant dip at around 100 Hz is often observed on the monitoring response, the transfer function from the loudspeaker to the listening position, in a small/medium sized mixing room. This paper studies the relationship between the dip at around 100 Hz and the effect of the presence of the mixing console. The generating mechanism of the dip is investigated by numerical simulations and experimental measurements. The results show that the reflection sound from the floor and the behavior of the mixing console as a cross over filter are important when considering the dip. Examples of trials for improvement of the dip are also examined.
