Mesa/Boogie pmn - Manual (Page 7)

Each channel of your amplifi er contains different modes of operation that may be selected depending on your application. In this way
you may decide to use the channels for their most obvious sounds or with the fl ick of a switch - invert the channels for the opposite
sound style. The voicing of the modes is accomplished by rerouting and reconfi guring the circuit in both pre-amp and power sections
of the amplifi er. Here are the choices;
CHANNEL 1
CLEAN : This is the lowest gain circuit of the RECT-OS’ fi ve modes and is optimized for producing balanced RECT-OS’ RECT-OS’
pristine clean sounds. For the best understanding of how to achieve a great sound in this mode, please refer
back to the GAIN Control section of this manual. However, a great place to start is 12:30 or so on the GAIN
Control with more sparkle available below this and more warmth apparent above...from there adjust according
to your guitars individual response.
Because of its more traditional architecture this mode also works extremely well for vintage style drive sounds. By turning the gain
all the way up, a beautiful old school solo sound is possible...especially with neck single coil pick-ups. The TREBLE and MIDDLE
Controls can also add gain and sustain to this sound ( reduce Presence to blend highs ), but you will probably want to run the BASS
Control below 10:30 to avoid fl ubbiness and preserve a focused attack.
PUSHED: This mode is a radical departure from the sweet shimmering blend of the CLEAN modes low gain character. Huge increases
in gain early on in the fi rst stages of the pre-amp produce one of the biggest differences between modes in the entire amplifi er and
transforms what you thought to be a tame and gentle clean channel into a raging crunch machine. This incredible amount of gain
also creates one of the most expressive solo modes in your RECT-O. Because there are less stages of gain for the signal to travel
through and the tone control network is tuned for the brighter nature of clean sounds, this mode responds quicker to your pick attack
and has a more urgent, snappy feel. Don’t overlook this mode for some of the RECT-OS’ coolest overdrive solo sounds.

NOTE: NOTE: NOTE: When using PUSHED with the GAIN Control maxed (5:30), do not run the TREBLE Control above (2:30). Settings above
(2:30) can create possible oscillation in certain preamp tubes in the V-1 position. This can be avoided altogether by setting the TREBLE
Control sensibly when the GAIN Control is maxed. Use the PRESENCE Control for additional brightness.
CHANNEL 2 / Modes
RAW: This new RECT-O mode has the lowest gain of the three in the high gain lead channel. Its’ less saturated nature greatly en- RECT-O RECT-O
hances the already versatile bevy of sounds the lead channel offers. 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 low and medium gain soloing potential RAW offers, as
its more gradual GAIN response produces a wide range of voice like single note sounds that are somewhat
more dynamic due to less saturation.
VINTAGE: This high gain mode is the famous liquid RECT-O voice and it can be found in its original state RECT-O RECT-O
here in CHANNEL 2. Its lush harmonic content and fat creamy feel has found its way onto so many recordings, it is now a staple for
anyone headed to the studio for an album project. Combining this super juicy, expressive preamp with the RECT-OS’ magic 50 watt
RECT-OS’ RECT-OS’
power section creates colors in gain that most players fi nd truly addictive. Single note solo work is effortless as the strings become
easy to play with
VINTAGE modes musical and natural tube compression. 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 identifi able. You will likely fi nd your new trademark lead sound lurking somewhere in this sea of liquid gain.
