Rogue Eighty-Eight Owners Manual 1Rogue Eighty-Eight Owners Manual 12

2) Remove Shipping Pallet - The amplifier is shipped attached to a
shipping pallet. This pallet serves two purposes. First, and
foremost it acts to tie down the mechanically isolated transformer
platform. Secondly, it provides strength to the main chassis. Both
of these items are 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. See Figure 1.
WARNING : Shipping this unit without correctly attaching
the shipping pallet can result in serious structural damage
to the unit.

MAINTENANCE
The Rogue Eighty-Eight 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.
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.
3) Remove the Top Cover - Using a phillips head screwdriver,
remove the top cover of the amplifier chassis. See Figure 2.
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.

4) Install Power Tubes - To avoid damage in transit, the power tubes
are shipped in a protective container inside the main shipping
container. Carefully unpack the tubes, and using a glove or a
clean dry cloth, install the tubes as shown in figure 3.
5) Inspect Input and Driver Tubes - Inspect the remaining tubes to
ensure that they are fully seated in their ceramic sockets. If a tube
appears to be tilted or otherwise dislocated, using a glove or clean
cloth, press down gently on the tube to reseat it in its socket. See
Figure 3 for tube locations.
OPERATING YOUR AMPLIFIER
1) Powering up the system - First turn on the amplifier by pushing in
the “power” button. The red LED will light after several seconds
after which the unit is ready for use. Always turn on the
preamplifier in the system before the power amplifier and source
materials, and always turn off the power amplifier first
2) Breaking in the amplifier - As with many high-quality audio
amplifiers, the sound of the Rogue Eighty-Eight amplifier will
improve during the first few 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

10) Polarity - The Rogue 88 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. If your preamplifier is also non-inverting, then connect
the positive (+) outputs of your power amplifier to the positive
(+) terminals of the loudspeakers and the negative (-) outputs to
the (-) negative loudspeaker terminals. If your preamplifier is
inverting, then connect the positive outputs (+) of you power
amplifier to the negative (-) loudspeaker terminals, and the
negative outputs (-) to the positive (+) loudspeaker terminals. If
you are unsure whether your preamplifier is inverting, check the
owners manual or contact the manufacturer. If all else fails, try
both connections and listen to which sounds better (do this using
several different recordings as not all recordings are made with
correct phase).
11) Amplifier Location - The Rogue 88 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.
WARNING - All vent locations should have 6 to 8 inches of
free space to allow for adequate cooling. Failure to ensure
this could degrade unit reliability.
WARNING - This unit should not be placed in an enclosed
shelf where hot air from the exit vent is recycled back into
the intake vent.
6) Select Mode - The Rogue 88 features a user selectable option of
running in either Triode or Ultra-Linear 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
b
oth 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 4 to the chosen settings. The unit is
shipped from the factory in Ultra-Linear mode.
Caution - Always ensure that all switches are set alike, in
either UL or Triode Mode

7) Matching Speaker Impedance - The Rogue 88 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 for the correct choice. To
switch impedance setting, refer to figures 5 and 6. 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.
⇒Place 4-ohm wire and lug onto red binding post.
⇒Place polyurethane tubing on the 8-ohm wire and lug.
⇒Replace nut onto binding post and tighten with wrench.
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 preamplifier are made via RCA jacks on the rear of the
amplifier. Be sure to use high quality interconnect cables - they
do make a difference.
