In the following picture is showing the placement of the output transformer TR5
corresponding to the OUT 1L (1) output. It is important to keep in mind the placement of the output
transformer pins so that they coincide with the main board (seven to the top and six to the bottom).
Remove the links corresponding to the output transformer. In this
case LK9 and LK10.
Place the output transformer, keeping in mind the
position of their pins (seven to the top and six to the
bottom), and solder it to the main board.
EQUALISER CARD
Two equaliser cards connectors are provided per output. Next table explains
the correspondence between the affected output and the labelled insert connector
as appears in the main distribution amplifier PCB.

When the eq card is not installed, the signal path must be closed with a jumper.
Keep in mind this circumstance whenever you change, update or place for the first time an
equaliser card. Of course, in order to insert the equaliser card, you should remove the connector
jumper in which you want to place the equaliser card.
