Mesa/Boogie Mark 5, Owner'S Manual, Page: 10 / 70

A ¼” TUNER OUTPUT is provided and a SILENT TUNING feature has been incorporated so you can tune the instrument on stage
without bothering the band or audience. Simply connect your favorite tuner and tap the TUNE the button on the
MARK V
Footswitch
and all sound to the Speaker Outputs is muted.
A SLAVE OUTPUT and SLAVE LEVEL Control allows you to capture the full sound of the MARK V , both preamp and power section,
for a feed to processing racks and/or additional power amps (perhaps MESA Stereo Rack power) for big venue applications.
NOTE: Always start any SLAVE hook-up procedure by zero-ing out the SLAVE LEVEL Control to avoid possible damage to your
speakers or your ears! In fact it is good practice to leave the SLAVE LEVEL Control set to 7:00 (OFF) when it is not in use to avoid
accidents.
The FOOT SWITCH DIN jack (female) is conveniently located on the right side of the Rear Panel and accepts a 7 pin male DIN cable.

MARK V
Footswitch here.
The Cooling Fan is fitted with an ON/OFF switch to allow silent running in the studio or late night practicing in the lower wattage set-
tings. We recommend leaving the FAN on whenever possible to increase the toneful life of your power tubes. Basically, if the sound
doesn’t bother you… leave the Cooling Fan on all the time.
Finally a BIAS SELECT switch is included that allows you to run EL34 power tubes in place of the stock compliment of 6L6’s. The
EL34 style tubes will produce a brighter, skinnier sound that will clip with a whole different harmonic content that can be nice, espe-
cially for recording where you may not need the Channel switching performance of all 3 Channels and can dedicate the amplifier to
one specific sound. The 6L6’S will most likely perform better for a wide range of sounds and certainly sound fatter and richer on most
all the sounds and produce the greatest clean headroom. Whichever tubes you prefer, MAKE SURE THE SETTING OF THE BIAS
SWITCH MATCHES THE TUBES IN USE!
NOTE: ALWAYS CHECK THE BIAS SWITCH AFTER SWAPPING TUBES AND EVEN AFTER TRANSPORTING YOUR AMPLIFIER!
THE BIAS SWITCH MUST BE SET FOR THE TUBES IN USE!
Now that you have had a bird’s eye view of the
MARK V
and a little history on the origin of some of the sounds, let’s start going
through the sounds and getting more specific with the function of the controls and how they interact…so you can get busy crafting
your signature sound!
