3. Reset
: Occasionally you may decide you don’t like what you’ve done to a channel. The
reset button allows you to reset all the filters of a channel to 0dB.
4. Bypass
: The bypass button lets you temporarily bypass the EQ of a channel to hear the
channel with and without equalization for A/B comparisons.
5. EQ
: This is the EQ band box. You can which of the 31 EQ bands you will adjust by clicking
on any of the green band buttons and using drag-n-drop, but you can also click into the EQ
band box and type in a band number or use the up/down arrows of the keyboard to scroll
through the bands.
6. Fr
: Similarly, the Fr: box lets you change the frequency of a band. If you have made an
adjustment and the frequency is not quite right, you can click into the Fr: box and move the
center frequency up or down with the up/down arrows.
7. Level
: As we said before, you can drag-n-drop a band button to make EQ adjustments, but
they will be rough adjustments. If you click into the Level box you can make fine adjustments
.5dB at a time using the keyboard arrows.
8. Q
: Clicking into the Q box lets you change the shape of the filter using the keyboard arrows.
While watching the RTA you can see exactly what your changes are doing to the acoustic
response as you make the the fine adjustments.
9. EQ Link buttons
: The first Equalization should always be done by R/L channel pairs. To do
this you use the EQ Link buttons. Example: Click Ch1 in the CH OUTPUTS column to open
Ch1. The Ch1 button 1 will be highlighted and the Ch1 row will be bright. Now you can
click 2 and Ch2 will become bright as well to let you know than Ch1 and Ch2 are linked.
The next time you click any channel in the CH OUTPUTS column the link will be broken.
Notes: a. You should only link 2 channels at a time b. After the first equalization you can
modify one channel or the other and then re-link them for further adjustment, but this
should only be done by experienced tuners. 99% of all installation will have the best results by
paired channel equalization c. It is possible to link all the channels except the Subs. The subs
can only be linked to each other. This linking again however should only be used by
experienced tuners.
10. Trace buttons
: You will always see the EQ and Crossover traces of the active channel
being worked on. The color-coded buttons at the left allow you to include other traces in
the graph so you can see how they interact.
11. The EQ graph
will always show all the available bands for the active channel as the
green band buttons. Before any adjustments they are all on the 0dB. After adjustment the
buttons will in their position on the response curve (the trace) you have set with your
adjustments.
