ANALOG AUDIO INPUTS
*4 Jumper-selectable to reduce sensitivity (see Appendix D). The given value is the factory
default.
ANALOG AUDIO OUTPUTS
*5 Not applicable to HDP-Express II.
*6 Jumper-selectable in five ranges up to 22.3 dBu balanced, 15.7 dBu unbalanced (see
Appendix D). The given value is the factory default.
*7 Into an earth-referenced amplifier i.e. one where the RCA ground pin connects to mains
ground. This is normally the case. The precise output impedance is 75 ohms, plus 75 ohms in
parallel with whatever the amplifier puts in series between its RCA connector and mains
ground. If the latter is open, then the impedance can be as high as 150 ohms (such as may
happen with a two-pin power connector).
