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. And with your Rogue Audio amplifier,
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 amplifier properly.
SETTING UP YOUR AMPLIFIER
tools required: phillips head screwdriver and a clean glove or cloth.
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.
1) Opening the box - Carefully remove the amplifier from the box.
It is important that you retain the packing material and box in the
event that the amplifier ever needs servicing. The packing
material and box have been carefully designed to protect your
valuable equipment during shipping so you don’t want to throw
them away!
Rogue Tempest Owners Manual 1Rogue Tempest Owners Manual 12

2) Remove Shipping Pallet - The amplifier is attached to a pallet
that supports the main chassis during shipping. This is critical to
ensure that no damage occurs in transit. After removing the
amplifier from the box and packing material, CAREFULLY turn
the unit upon its side. Remove the 4 thumbscrews and washers.
Retain these screws and pallet in the event that the unit ever needs
servicing.
WARNING : Shipping this unit without correctly attaching
the shipping pallet can result in serious structural damage
to the unit.
3) Remove the Top Cover - Using a phillips head screwdriver,
remove the top cover of the amplifier chassis.
WARNING - If the unit has been powered up, you must
turn off the power at the switch and wait at least one hour
before disconnecting the electrical cord. After doing so, the
unit may be unplugged and the top cover removed. This
time is required for dangerous voltages to dissipate.
ADDING A ROGUE EIGHTY-EIGHT POWER AMP
One of the features of the Tempest is that a Rogue Eighty-Eight
power amplifier can be added at a later date to increase the system
power. It is important to use a Rogue Eighty-Eight amplifier so that
the power levels are equivalent between the two amplifiers for a given
input signal. It is also required that the speakers are capable of being
biamped (Separate inputs for tweeters and woofers) The procedure
for biamping is as follows:
1) Remove the shorting connection on the speakers between the
tweeter and woofer inputs.
2) Attach the Speaker wires from the Tempest to the tweeter
connectors on the loudspeakers.
3) Attach speaker cables from the Eighty-Eight amp to the woofer
connectors on the loudspeakers.
4) Connect the active outputs of the Tempest to the inputs of the
Eighty-Eight amp.

6) Select Mode - The Rogue Tempest features a user selectable
option of either Triode or Ultra-Linear operating modes. Some
listeners prefer pure triode operation, however, it does limit the
power output of the amplifier to approximately 40 watts per
channel. Ultra-Linear operation offers the amplifier’s full rated
output power of 60 watts per channel. The user is encouraged to
try both modes and determine their own preference.
WARNING - If the unit has been powered up, you must
turn off the power at the switch and wait at least one hour
before disconnecting the electrical cord. After doing so, the
unit may be unplugged and the top cover removed. This
time is required for dangerous voltages to dissipate.
To switch modes, use a nonconductive screwdriver to flip the 4
switches shown in Figure 2 to the chosen settings. The unit is
shipped from the factory in Ultra-Linear mode.
Caution - Always ensure that all 4 switches are set alike, in
either UL or Triode Mode
MAINTENANCE
The Rogue Tempest has been designed to provide many years of
enjoyable and reliable service. The greatest care has been taken to
select vacuum tubes that provide superior sound and ensure long life.
However, at some point in time, the tubes will wear out. The factory-
installed tubes should last thousands of hours. Should it become
necessary to replace a tube, follow the instructions listed below.
Replace Tubes by :
1) Turn off power at switch.
2) Wait one hour for dangerous voltages to dissipate.
3) Unplug power cord from wall socket.
4) Remove the top cover. See figure 2.
5) Using a glove or clean dry cloth, carefully remove the tubes from
their sockets - DO NOT TOUCH ANY OTHER ELECTRICAL
COMPONENTS.
6) Obtain and insert a new set of tubes. It is recommended that a
new set of tubes be obtained from Rogue. If tubes are obtained
from another source, follow the diagram in figure 3 for tube type.
7) Insert new tubes in sockets using a glove or cloth. See figure 3 for
locations.
No other items in the unit are designed to be user serviceable.

OPERATING YOUR TEMPEST
1) Delays- Note that the Tempest is equipped with a slow turn-on
feature that protects other equipment from dangerous transients at
turn-on as well as significantly prolonging tube life.
2) Powering up the system - First turn on the amplifier by pushing in
the “power” button. The red LED will light showing that the unit
is powered up. After approximately 10 seconds the outputs will
disconnect from ground. After another 10 seconds, the control
section will be unmuted and the Tempest is ready to play music.
Note : This unit will not play for approximately 20 seconds
after power on while tubes warm up.
3) Switches and Controls - The Tempest is equipped with volume,
balance, source, power, mute, and an optional remote volume .
•Volume – adjust gain from 0 to 23Volts out
•Balance - left and right channel attenuation
•Source - selects source material (CD, phono, tape, tuner, aux, preamp)
•Power - on/off operation
•Mute - mutes output
Remote Volume Control - The Tempest is optionally equipped with an
analog remote volume control feature. The volume may be
adjusted manually using the knob on the front panel, or by using
the remote control provided.
4) Breaking in the amplifier - As with many high-quality audio
amplifiers, the sound of the Rogue Tempest amplifier will
improve during the first 50 to 100 hours of use. This time is
required for components to “burn in.” No special techniques are
required other than standard operation.
Note: This unit will not sound its best until the tubes have
warmed up. This will take approximately 5-10 minutes
7) Matching Speaker Impedance - The Rogue Tempest provides
options for either 4 ohm or 8 ohm speakers. The impedance
selected will depend on the speakers used. Consult either the
owner’s manual for your speaker or your local dealer to
determine the correct choice. To switch impedance setting, refer
to Figure 3. Note - the amplifier is factory set for 8-ohm
speakers.
⇒Using a 5/16” wrench, remove the outermost nut from the
red binding post.
⇒Remove the wire and lug marked 8 ohm from the binding
post. Leave the wire and lug marked feedback in place.
Warning -Never remove the lugs marked feedback or
ground from the binding posts. Doing so could cause
permanent damage to the unit
⇒Remove the polyurethane tubing from the unused 4-ohm
wire and lug.

8) Attach Power Cord - Connect the IEC end of detachable power
cord to the amplifier, and plug opposite end into corresponding
outlet.
9) Connections to other components -. The input connections from
the musical source are made via RCA jacks on the rear of the
amplifier. Be sure to use high quality interconnect cables - they
do make a difference.
10) Polarity - The Rogue Tempest amplifier is a non-inverting
amplifier (positive signal in gives positive signal out) so, for best
sound, care should be taken to ensure correct polarity at the
speaker terminals. Connect the positive (+) outputs of the
Tempest to the positive (+) terminals of the loudspeakers and the
negative (-) outputs to the (-) negative loudspeaker terminals.
11) Amplifier Location - The Rogue Tempest amplifier is an enclosed
tube design with forced air ventilation and cooling. This cooling
has been designed and tested to ensure long term reliability and
safety of the unit. The amplifier should be placed in such a way
that this airflow is not impeded. See Figure 7.
USING AN EXTERNAL PREAMPLIFIER
The Tempest offers the flexibility of adding an external
preamplifier should the user wish to do so. In the external preamp
mode the Tempest preamp is completely bypassed and only the
power amplifier section is used. To set up the Tempest for use
with an external preamp perform the following steps.
1) Remove the cover
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
2) Locate the four small shunts on the control circuit board as shown
in figure 4.
3) Using a needle nose pliers carefully remove the four shunts from
the locations marked “int pre” and move them to the adjacent
locations marked “ext pre.”
4) Rotate the selector knob to preamp on the front panel.
5) Connect the external preamp to the inputs on the rear panel
marked preamp.
