Audio Wiring
Audio Wiring for Use with Single Ended Audio Inputs. (i.e.: FDACS)
For best performance, use four individual wires or two twisted pairs in a shielded cable.
The four audio wires would be connected to Left +, Left -, Right +, Right -.
All four wires will run from the Blu-ray player to the destination.
Left + and Right + connect to the Left and Right signal inputs respectively.
Left
– and Right – will join together at the destination and connect to the receiving
equipment’s audio return pin. The shield will be connected to the fuselage at one place
only.
Audio Wiring for Use with Balanced Audio Inputs
For best performance, use two twisted pairs in a shielded cable or two individual
shielded twisted pairs.
One pair is connected to Left + and Left -. The other pair connects to Right + and Right
-
All four wires will run from the Blu-ray player to the destination.
Left + and Left
– connect to the receiving equipment’s Left channel input.
Right + and Right
– connect to the receiving equipment’s Right channel input.
The shield will be connected to the fuselage at one place only.
NOTE:
The FD932DVD-BLU-2 (VER HDSDI) has high impedance balanced outputs instead
of the more popular low impedance inputs. This is usually not a problem. External audio level
pads may be installed at the installer’s discretion.
