INTRODUCTION

Congratulations on your purchase decision! We at Rogue Audio truly believe that
our preamplifiers provide the “smartest” value in high-end audio. If you have
never owned a vacuum tube preamplifier you will be thrilled by the silky-smooth
sound and incredible detail that only a tube preamplifier can provide. And with
the Hera preamplifier, you can be sure that you are getting the very best in tube
amplification. We at Rogue Audio are extremely proud of our products and want
you to enjoy them to their fullest potential. So please, take the time to read
through this short manual so that you can be confident that you have set up your
preamplifier properly.

UNPACKING THE HERA POWER PREAMPLIFIER

Tools required: none

WARNING - This preamplifier uses voltages that could cause injury or
death. Never open the preamplifier while it is plugged in, and always
wait at least one hour after turning the unit off to unplug and open the
unit. Lethal voltages can remain in the electronics after the unit is
unplugged.

The Hera preamplifier has been painstakingly inspected for cosmetic flaws during
and after assembly. In order not to damage the cosmetic appearance of your
preamplifier it is important that you follow the unpacking instructions carefully.

1. Open the shipping carton and remove the remote control, power cord and

power supply cables from the corners of the carton.

2. Carefully lift the preamplifier out of the carton, and remove the foam pads and

plastic bag.

3. Carefully lift the power supply out of the carton, and remove the foam pads

and plastic bag.

4. Save the packing materials. The packing materials and box have been

carefully designed to protect your valuable equipment during shipping so you
don’t want to throw them away.

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.
