RUN AutoEQ/LEVEL ASSIST
When used with the optional dbx RTA-M
measurement microphone, this Wizard
helps you balance the left/right speaker
levels, the low/mid/high speaker levels
(for 2-way and 3-way systems), and
automatically equalizes the speakers to the
current room environment. After selecting
this option, you can select whether you
would like to run both the Level Assist and
AutoEQ functions, Level Assist only, or
AutoEQ only.
The diagrams to the right show the
recommended Level Assist and AutoEQ
RTA-M mic positions. When running
AutoEQ, you will be prompted to select how
many mic positions you would like AutoEQ
to analyze – the selections are: 2, 3, or 4.
The Level Assist and AutoEQ mic position
1 measurements should be taken with
the microphone placed out in front of
the speakers the same distance as the
speakers are apart, so that the three
components form an equilateral triangle,
as shown in the Level Assist/AutoEQ Mic
Position 1 diagram.
Each time you move the RTA-M mic
position it should move approximately
1/3rd the distance the speakers are apart
from the initial “RTA-M Mic Placement 1
Reference”, as shown in the AutoEQ Mic
Position 2-3 diagrams. Mic position 4 is the

exception as it should be placed 2/3rds the distance from the RTA-M Mic Placement 1 Reference. For example, if your
speakers were 20 feet apart, you would move the microphone approximately 7’ (20 * (1/3) = 6.6) from the RTA-M Mic
Placement 1 Reference for mic positions 2-3 and approximately 14’ from the RTA-M Mic Placement 1 Reference for mic
position 4. However, as a general rule of thumb and for the sake of simplicity, a distance of 5’ should work well for most
venues. If the recommended placement of the mic in positions 2-4 is not possible, just place the mic in a position that differs
from the other measurement positions.
RUN AFS WIZARD
This Wizard walks you through the process of ringing out the system to provide higher system gain before feedback. This is
accomplished by pushing your system into feedback so AFS can detect the initial frequencies which cause feedback and notch
them using Fixed filters. When the AFS Wizard is complete, it will automatically enable the Live filters, for automated protection
during system use.
