Mesa/Boogie Mark 5, Owner'S Manual, Page: 20 / 70

CAUTION: The EXTREME Mode is LOUD in both these amplifiers…Use Care and Zero out the OUTPUT Level Controls before
beginning this comparison
SET MARK IV As Follows:
Channel 3 (LEAD)
LEAD GAIN (FAR LEFT) Pulled and set to 7 ¾
LEAD DRIVE Pulled and set as desired
Channel 3 (LEAD) Tone Controls set as desired.
Pull All Controls (unless comparing EXTREME - then leave LEAD PRESENCE Pushed In = EXTREME)
PRESENCE set as desired (0 or 10 is most fair and removes pot variance)
Rear Panel TRIODE / PENTODE switch set to PENTODE
Set
MARK V
As Follows:
Channel 3 set to MK IV or EXTREME Mode (Make sure set the same as MARK IV)
GAIN set to match relative “clock face” setting of numeric LEAD DRIVE setting on MARK IV.
Channel 3 Tone Controls set to match relative “clock face” settings on Mark IV.
Channel 3 BRIGHT / NORMAL switch set to BRIGHT (switch down).
Channel 3 PRESENCE set to relative setting on MARK IV.
Rear Panel TRIODE / PENTODE switch set to PENTODE (switch up).
Rear Panel EFX LOOP switch set to ACTIVE (switch up).
You cannot hear the MK II C+ Mode in the
MARK V’s
response in an older MARK Series model because the coupling cap at the
end of the EQ in those amps is simply too big and is adding too much slow-lows to be a fair comparison.
NOTE: These comparisons are as close as possible regarding the setting and configuration of the circuits. When doing these types
of tests it is important to take into account that the power tubes, preamp tubes, transformers and even the caps and resistors may be
different depending on availability at the time of construction.
