Using the DACS HeadLite2
Installation
1 Connecting the Power
The unit will accept 240 VAC and 110 VAC mains supplies. The IEC inlet’s fuse holder
is used as a selector as shown in Fig 2. The factory setting is for 240 VAC.

3 & 6 Outputs
Connections
The outputs are on three pole ¼” jack, tip=left, ring=right, sleeve=0V. They are
connected in parallel. The output circuitry is designed to drive down long lines with
minimal high frequency loss. If you are sending headphones signals down long lines
using screened twin conductor cable (such as foil screened twin, FST), we would
recommend using two separate cables if you can. This would reduce any possible
cross-talk between the left and right channels. There are installations we know of
where left and right are sent down the two conductors, and all reports have been
good.
If two or more pairs of headphones are to be driven by an output, they should be of
the same type and impedance. If they are different (eg. low and high impedance),
power sharing will not be even. One will be too quiet, and to achieve the required
level in that pair, the other pair will overload.
