INSTALLING THE HERA INTO YOUR SYSTEM
Connecting the Power Supply to the Preamplifier
The Hera Preamplifier is a two box preamplifier, where the power supply and
AC/DC conversion is placed in a separate box to lower the noise floor of the unit.
The preamplifier chassis is designed to sit directly on top of the power supply
chassis, see Figure 1. The two boxes may be placed on different racks if this is
more convenient in your system and optional longer cables are available from
Rogue Audio if needed. There are three cables provided with the Hera for
connecting the power supply to the preamplifier. These are four, five and six
conductor cables. See Figure 2. These cables have both male and female ends on
them. Connect the four conductor cable to the power supply using the male end of
the cable and then connect the cable to the preamplifer using the female end of the
cable. Do the same for the five and six conductor cables. It is important to make
these connections before connecting the power cord to the wall outlet. Note that
certain critical portions of the Hera circuitry remain energized even when the unit
is turned off so do not disconnect any of these cables while the power supply is
plugged into a power outlet.
Warning – Never disconnect any of the three cables while the power
supply is plugged into a power outlet.
When moving the preamp always turn off the power, wait 15 minutes and then
unplug the preamp from the power outlet before disconnecting any of the three
rear cables.
