Using the DACS HeadLite2

Installation
1  Connecting the Power

The unit will accept 240 VAC and 110/115 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.

2 & 5 Inputs
Connections

Inputs A, B, C and D are on three pole ¼” jack sockets, 
sleeve=0V).  Unbalanced  signals  may  be  used  on  two  pole  jacks.  The  input 
impedance is 10k ohms.

If no connector is plugged in, the inputs are shorted to 0V via the switch connections 
on the jacks. If the inputs are connected to a patchbay, it is advisable, if possible, to 
normalise them. Do this at the patch bay. If   they are not normalised and are left 
floating, they may be prone to pick up interference, taxis or the radio over long lines 
between the unit and the patchbay.

Levels

The input buffer’s sensitivity can be adjusted for +4dBu or -10dBV operation using 
the  switches.    Note:  Channel  A  &  B  sensitivity  are  selected  by  one  switch  and 
Channel  C  &  D  sensitivity  by  the  other.    It  is  not  possible  to  select  different 
sensitivities for each one of the paired channels.
