Orban 5750 Technical Manual Technical Data 6-1
Section 6: Technical Data
J613:
As shipped from the factory, a jumper is kept across pins 1 and 2 of J613, and a second jumper is kept across its pins
3 and 4. The jumpers engage the direct connection from AES/EBU DIGITAL INPUT 1 to AES/EBU DIGITAL OUTPUT 1
made by the relay bypass function when OPTIMOD processing is unavailable.
To disengage the direct connection just described, the user should remove both of those jumpers. Removal of the
jumpers will be necessary in most configurations involving use of AES/EBU DIGITAL OUTPUT 1 as a DMPX source.
J614:
As shipped from the factory, a jumper is kept across pins 1 and 2 of J614, and a second jumper is kept across its pins
3 and 4. The jumpers engage the direct connection from AES/EBU DIGITAL INPUT 2 to AES/EBU DIGITAL OUTPUT 2
made by the relay bypass function when OPTIMOD processing is unavailable.
To disengage the direct connection just described, the user should remove both of those jumpers. Removal of the
jumpers will be necessary in most configurations involving use of AES/EBU DIGITAL OUTPUT 2 as a DMPX source.
J501/J502:
As shipped from the factory, J501 (composite 1) and J502 (composite 2) are across pins 3-4 for 0Ω impedance on
their respective composite output. Switching to pins 1-2 sets the impedance to 75Ω.
