Mesa/Boogie II Stereo Amplifier User Manual


 
CHANNEL 2 MODES:
RAW: This
Recto
mode is the lowest gain of the three in CHANNEL 2 s’ high gain lead channels. Its less saturated nature greatly
enhances the already versatile bevy of sounds the two original lead channels offered. The range of gain available covers an extremely
wide spectrum and it can be set to double as a formidable alternate clean mode, a low gain purring blues sound and beyond, all the way
up to a grinding crunch or searing solo sound. The TREBLE can be set relatively high (2:00) to add a
little more gain and shred when using RAW for certain crunch rhythm sounds. Don’t overlook the
amazing medium gain soloing potential RAW offers in CHANNEL 2 where, because of its more gradual
and responsive GAIN taper, a wide range of voice like single note solo sounds appear that benefit from
this more compressed, less saturated character.
VINTAGE: This high gain mode is the famous liquid
Recto
voice and it can be found in its original state
in CHANNEL 2. Its lush harmonic content and fat creamy feel has found its way on to so many record-
ings, it is now a staple for anyone headed to the studio for an album project. Single note solo work is
effortless as the strings become easy to play with VINTAGE modes musical and natural tube compres-
sion. Spend time learning the lower regions of the VINTAGE mode as the overlap between RAW and VINTAGE is a place where many
beautiful sounds lie. These two modes are similar enough when VINTAGE is set in its lower range and RAW is set in its medium to higher
range, and yet each possesses a character that is unique and identifiable.
MODERN: Aggressive. This is the word that best describes the menacing power of the
Rectos
most rebellious of all modes and appears
in its original form in CHANNEL 2. A take no prisoners, crushing assault of top end cut and lightning fast response creates a sound of
unparalleled aggression that has set a new standard for hard core sounds. The added tightness of the low end response combined with
the radically more present top end keeps the MODERN mode tracking accurately even at extreme gain settings.
NOTE: Keep in mind that the CHANNEL 2 MODERN experience can be further enhanced in a LIVE application by using the companion
power amplifier, the
Rectifier Stereo 2:100.
By connecting the EXT. TRIGGER MODERN jack on its Rear Panel to the
Recto Preamps’
MODERN trigger jack the power amp will track the preamp MODERN mode and auto-remove the negative feedback every time you select
MODERN on the preamp. This scheme duplicates the sonic authority as it recreates the exact circuit of the
Dual Rectifier Solo Head
in this rack mount platform.
NOTE: There is a slight volume drop when switching between CHANNEL 2s’ VINTAGE and MODERN modes when you are using the
RECORD OUT jacks connected to a console. This is a result of having to recreate the sound of the MODERN mode without a power amp
to remove negative feedback from. We duplicated the sound by notching the same frequencies that become recessive in the re-voicing
that occurs in the solo heads when the negative feedback is removed and are pleased with the results of this challenging task. The sound
has been created here without the unruly power section and the only thing
Recto
head owners may have to get used to is not getting blown
out of the room as you flip to MODERN. And if you just can’t get used to the well behaved operation direct, you can always connect up the
companion power amp and follow the above NOTE and blow yourself down.
THE TONE CONTROLS:
GAIN: Like most amplifiers, the GAIN Control in each channel determines its sensitivity and overall tonal characteristics. It meters the
amount of Gain that your guitar signal will produce. In the
Recto Recording Preamp,
we paid special attention to the amount and
frequencies of gain present in each mode, making sure the whole range of available gain is musically
usable. We also worked diligently with our suppliers to develop pots with tapers useful to players that
require that touch sensitive relationship of input signal level to gain saturation. An essential ingredient to a
great amps expressive nature. To maximize your expression, spend time learning the different regions of
the GAIN Control in each mode and tonal colors they enhance. Almost more - or certainly equal to the tone
controls - the GAIN Control shapes your sound.
