As seen in the previous picture, the switch 1 activates (at right) or disables (at left) the
limiter (with the limiter inactive, the configuration of the other switches is indifferent). With the
switch 6 you can configure positive dBv (at right) or negative (at left). The other switches 2,3,4
and 5 configure the number of dBv, in a binary addition manner, so that the number of
configured dBv is the sum of these switches that are located at left, those that are located at
right will always be in 0 dBv. Next is illustrated a series of limiter configuration examples:
Limiter inactive.
Limiter adjusted at +3 [dBv].
Limiter adjusted at- 5 [dBv].
Limiter adjusted at 0 [dBv].
EQUALIZER CARD
It is available an equalizer card as option, that has a point of parametric equalization,
because of it has the three parameters of a equalization point adjustable: gain, frequency
and Q (bandwidth). Each way of the crossover could have two equalizer cards. In the next
table are shown the connectors of the main board where these equalizers cards could go, in
function of the way that you want insert a point of equalization:

If any of these connectors doesn't have an equalizer card, or how
you will see later on of delay card, this way should have a jumper in the
connector as you can see in the next picture, since of if this way doesn't
have this jumper, the signal would remain off and therefore that way
wouldn't work. Keep in mind this circumstance whenever you change,
update or place for the first time an equalizer or a delay card. Of course
in order to insert the equalizer or delay card, you should remove the
connector jumper in which you want to place the equalizer or delay card.
As seen in the main board component overlay, the jumper goes
placed beside an indication. It is important notice well where the jumper
goes located, because place it in other location could cause a short
circuit in the power supply, and cause the crossover break.
