Mesa/Boogie Dual Rectifier Road King Amp Owner's Manual page 6

OVERVIEW: (Continued)
4 provide different levels of the same lower gain solo sound. Conversely, a Rock player might configure 1 & 2 for semi-clean and
pushed rhythm sounds respectively and dedicate 3 & 4 to high gain crunch rhythm and lead sounds using different settings of the
same modes.
This type of preamp versatility means you will never have to compromise, even when you change bands or venture into a new and
different style with your playing...and you've chosen an amp that will grow with you.
This awesome preamp power is then sent to the Road Kings' Effects Loop section and we have provided both Series and Parallel
Loops to assure a match to whatever type of processing you choose. These may be used individually or combined, and may be
programmed active in any of the channels or, footswitched in and out on the fly.
From there we reach the coolest feature of all and the reason why the Road King is just that...our patented Progressive Linkage
switchable, and in this case assignable, power section. That's right, any of the 4 preamps can be combined with any one of the 5
power section configurations! You choices are the bubbly, elastic 2 x 6L6; the urgent, brash 2 x EL34; the tight, bold 4 x 6L6; the
elusive, stinging 2 x 6L6 + 2 x EL34; and the huge, dominating power of 4 x 6L6 + 2 x EL34.
Each of these power configurations lends its own personality and when matched with the right preamp can sonically define a musical
style. But it doesn't end there...the Road King also features Rectifier Tracking, a feature which automatically matches the type of
rectification for each of the preamp / power sections you have configured. This means you can tune the power feel even further to the
sound you are creating. You might want a lower wattage clean sound with the loose, airy feel of Tube Rectification and a high gain lead
sound with higher power and the tight tracking bass response of the Solid State rectifier or vice versa. Many combinations are
possible and the best part is that Rectifier Tracking follows your choices in power sections to always mate the proper amount of
rectification for a given string of tubes. For example, if you are using either 2 x 6L6 or 2 x EL 34 and you choose Tube rectification, 1
x 5U4G will be applied. If you use either 4 x 6L6 or 2 x 6L6 + 2 x EL34 2 x 5U4G will be used. And finally, if you choose to run all six
power tubes (4 x 6L6 + 2 x EL34) then the Silicon Diodes will be called up, ensuring that you have maximum headroom at all times.
This Rectifier Tracking feature provides one more layer of focus to an already mindbending array of sounds to create the most
expressive amplifier available anywhere.
And if this versatility isn't enough, add to the palate Programmable Channel-specific Speaker Switching! That's right, you can utilize
two different types of speaker enclosures to enhance different sonic characteristics and combine these choices with each Channel/
Mode scheme. Use an open back 2 x 12 cabinet for more shimmering clean performance and switch to a closed back 2 x 12 for a
bigger, more compressed lead sound. There are even provisions for using two cabinets of different impedance loads...the choice is
yours.
The Road King incorporates a rich analog Reverb, which is controlled per channel with the Rear Panel Reverb controls and may be
switched in and out via the King Kontroller.
Our SOLO feature is an additional Output Level control that is wired in parallel to the Output and provides a pre-assignable, footswitchable
boost for stepping out when it's time to solo.
A built-in Variac, our patented SPONGY/BOLD switch, is also included which enables you to reduce the A.C. line voltage for a looser
feel and increased upper harmonic spread resulting in that brown sound that has the elusive sag.
And finally, to keep you in constant control of all the features aboard this vehicle of expression, we have supplied one of the mightiest
footswitches around...the King Kontroller. All possible Channels, Functions and Features are there for your instant access and
their status is monitored by LED illumination.
So with an overview of the basic layout of the Road King behind us, let's get ready to play.
1.) After unpacking the amplifier remove the plastic webbing from all of the tubes (including the preamp tubes behind the row of
power and rectifier tubes) and make sure all tubes are seated firmly in their sockets.
