Outputs

The standard outputs are electronically balanced and is capable of driving
+19dBu into 600 ohms and +20dBu into 2K.

It is recommended that the equaliser feeds into a balanced input, however to feed an unbalanced
input it is necessary to connect the antiphase output to ground. This is best carried out on the XLR
output connector of the equaliser.

Note: When using a fully balanced system, either pin 2 or pin 3 can be phase.
