INTRODUCTION
Congratulations on your purchase decision! We at Rogue Audio truly believe that
our amplifiers provide the “smartest” value in high-end audio. If you have never
owned a vacuum tube amplifier you will be thrilled by the silky-smooth sound
and incredible detail that only a tube amplifier can provide. The Medusa and
Hydra hybrid amplifiers combine the best of tube and solid state amplification to
give you great tube amp sound without any of the normal tube amp maintenance.
At Rogue Audio we 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 amplifier properly.
UNPACKING YOUR AMPLIFIER
Tools required: none
WARNING - This amplifier uses voltages that could cause injury or
death. Never open the amplifier 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.
Your amplifier has been painstakingly inspected for cosmetic flaws during and
after assembly. In order not to damage the cosmetic appearance of the amplifier it
is important that you follow the unpacking instructions carefully.
1. Carefully lift the amplifier out of the box, and remove the foam pads and
plastic bag.
2. 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.
3. Using a glove or a clean dry cloth, straighten any tubes that may have tilted
during shipment. Ensure that all of the tubes are fully seated in their ceramic
sockets.

HOOKING UP YOUR AMPLIFIER
Connecting the amplifier to the loudspeakers:
The rear panel has five way binding posts with which you can connect your
loudspeakers as shown in Figure 1. These binding posts accommodate any of the
popular speaker terminations available including spades and bananas.
Connecting the amplifier to the preamplifier:
There are two types of input connections on the rear panel of the amplifiers:
1) Fully balanced XLR type input.
2) RCA input
The input connections can be made using either the XLR or RCA input,
depending on your system setup.
Note that if you have a variable output CD player you can choose to drive the
amplifiers with it directly.

Connecting the amplifiers to the power outlet:
Connect the IEC end of the detachable power cord provided to the amplifier and
plug the opposite end into a suitable power outlet. It is recommended that the
amplifier and your preamplifier are plugged into the same wall outlet if possible
(perhaps using a power outlet strip). This is to avoid creating a ground loop.

OPERATION OF YOUR AMPLIFIER
After all proper connections have been made you are now ready to turn the
amplifier on. The main power on/off switch is on the rear of the amplifier and
should be left on at all times. A small amount of power is used by the amplifier to
maintain a ready state which keeps the solid state components warmed up for
better performance. The power switch on the front of the amp is used to turn on
and off the tube circuitry as well as to take the solid state components out of their
standby mode. There are three LED’s on the front panel as shown in figure 2.
The yellow LED indicates that the amplifier is in standby mode. The blue LED
indicates that the amplifier is fully operational. The red LED indicates that a
problem has occurred (shorted speaker terminals or other source of overcurrent).
When the unit is first plugged in and the rear switch is turned on the red LED will
blink briefly and then the yellow standby LED will be illuminated. When the front
power button is first depressed both the blue and yellow LED’s will be
illuminated. After approximately 10 seconds the yellow LED will turn off
indicating that the amplifier is operational and ready to play music.

Some preamplifiers and sources can generate dangerous transients that can
damage loudspeakers. To avoid letting dangerous transients reach your
loudspeakers turn your system on in the following order:
1)
2)
3)
4)
5)
Turn on all sources (CD, tuner, etc.) that you will be using.
Turn on the preamplifier.
Wait until the preamplifier has stabilized.
Power up the amplifier
Select listening source and play music
When powering down your system turn the amplifiers off first.
Note – After turning off the amplifiers, wait at least one minute to turn them back
on. Do not turn them on then off and then on again in quick succession. Doing
this will not allow the power supplies to discharge between on/off cycling and
may result in dangerous transient noises.

TROUBLESHOOTING
Speaker Hum – If hum can be heard from more than a few inches from the
loudspeaker, there is probably a ground loop. Be sure that the amp and preamp are
both plugged into the same outlet or power strip. If this fails to cure the hum, call
customer service at Rogue Audio for further advice.
Red LED on front panel is illuminated – Check speaker wires to see if they are
shorted together at the rear of the amp or at the speakers.
Sound from only one speaker – Check that your speaker cables and interconnects
are properly connected.
No LED’s are illuminated – Check that the power cord is properly installed and
that the rear switch is turned on.
If you still have a problem please contact Rogue Audio at 570-992-9901
