Configuration Chart
Furthermore individual jack pairs can be changed to combine various normallings within one
panel quickly and without fuss. This is even possible while the panel is "on air". For this we offer
pre-configured jack pairs (NJ3TTA-4-*).
In case of emergency the normalling for individual jack pairs can be changed by the use of
normalling bars. Normalling bars to change the normalling of 4 channels are included.
