Rogue Audio Rogue Sixty Six - Manual (Page 6)

OPERATING YOUR PREAMPLIFIER
1) Delays- Note that the Rogue Sixty-six 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.
This feature is provided via several timing circuits that allow the
tube filaments to reach operating temperature before turning on
the high voltage supply. The outputs are muted during this
sequence and then opened after turn-on transients have been safely
dissipated to ground.
2) Powering up the system - First turn on the preamplifier by
pushing in the “power” button. The red LED will light after
several seconds. After approximately 10 seconds, the high
voltage supply will turn on. After an additional ten seconds, the
outputs will disconnect from ground and the preamp is ready.
After turning on the preamplifier, turn on the power amplifier
and source material and you are ready for listening.
Note : This unit will not play for approximately 20
seconds after power on while tubes warm up.
3 ) Switches and Controls - The Rogue Sixty-six is equipped with
volume, balance, source, power, mute, (and record on phono version
only).
• Volume - gain adjustment from 0- 23 dB
• Balance - full left and right channel attenuation
• Source - selects source material (CD, phono, tape, tuner, aux1, aux2)
• Power - on/off operation
• Mute - leaves preamplifier on while muting output
• Record - must be pressed in while taping, isolates tape player when not
taping .
4) Remote Volume Control - The Sixty-Six LSR (line stage remote)
is 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.
5) Leaving the System Running - Unlike many solid state
amplifiers, the Sixty-Six preamplifier should not be left turned
on when not in use. To prolong tube life, turn off the unit when
not being used.
MAINTENANCE
The Rogue Sixty Six 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.
In addition, this unit utilizes a slow turn on feature which helps
prevent cathode stripping during power up. This feature will greatly
increase usable tube life.
Replace Tubes by :
1) Removing the top cover by unscrewing 10 screws.
2) Using a glove or cloth, carefully remove the tubes from their
sockets.
WARNING : If unit has been powered up, you must
turn off 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 ground.
3) 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 2 or 3 for tube
type.
4) Insert new tubes in sockets using a glove or cloth. See figure 2 or
3 for locations.
