Error trying to activate top or height speakers without the lower level speakers. If you only can position
surround speakers in the ceiling, these must be designated as lower level surround speakers, as you are not
creating a 3-dimensional sound field.
As a rule of thumb, don´t make changes if you are not familiar with the consequences, and always make a
backup before trying out other speaker setup options. When you change a size of speaker, LFE cut-off or
any distance or delay settings, you need to do a new RoomPerfect calibration, as the interaction between
room and speakers are changed.

Speaker Size
When selecting a speaker size, you set the bass-cut-off frequency, and the signal information below this
frequency will be sent to the subwoofer(s). By selecting CUSTOM, you can specify the cut-off frequency
directly.
Gain
If a specific speaker channel is significantly lower in level compared to the other channels, you should
decrease the gain on the highest channel to match the overall level of speaker output. (increasing gain on a
speaker channel might cause a speaker or subwoofer to distort at levels below 0 dB). Even levels ensures,
that the subsequent RoomPerfect™ calibration will run perfectly. (highest and lowest speaker levels are then
within the microphones optimal calibration levels)
