Treble - Mesa/Boogie Royal Atlantic RA-100 Owner's Manual

FrONT PANeL: C
saturation to keep chords grinding and single notes hanging – but not too much to start compressing the life out of the sound. If you
aren't getting great results in this region for your gain sounds in Channel 2, you may want to look at trying some pickups with a bit
hotter output.
The highest region of the GAIN (2:00 – 5:00) is all about saturation. Up here the signal gets much fatter in the low end and the top
end begins to recede to create a round, compressed sound. Dynamics become slower with lower peaks and a more legato, creamier
feel is produced. In Channel 1 the high end of the GAIN control produces some great clipped clean sounds as the Input stage gives it
up and starts to saturate. These sounds are further enhanced by the 50 Watt Power Mode and the Multi-Soak™ Attenuation feature,
where you can add additional power clip to the preamp drive.
Channel 2 gets truly wild at the top end of the GAIN control and both Modes unveil their true potential as solo Modes. There is ample
gain up here to rip into any style you wish with the HI Mode pumping out ridiculous levels of thick creamy overdrive for soloing. With
the GAIN maxed in HI you can achieve virtually infinite sustain... if you can keep your guitar stable and from feeding back. The more
midrange-prominent character of LO and HI allows you to still have good articulation up here even with amounts of saturation that
would turn most circuits to useless mush.
At the highest GAIN settings you will notice the Tone controls have a diminished effect on the sound as the notes are so saturated
and their character has been pre-determined by the way each Mode is voiced and how it reacts to this level of gain. May we humbly
suggest using the GAIN in its middle range whenever possible to achieve the best balance of overdrive and still retain the full shaping
power of the Tone Controls. Also, your attack will remain definitive and focused in the middle range and not get over-saturated and
"slowed down" as it can in the highest region of GAIN settings.

TREBLE:

While the VOLUME is the most powerful control in the Royal Atlantic, the TREBLE comes in a close second. The
TREBLE is responsible for shaping the character of the entire Mode/Channel. It can overpower the rest of the Tone controls easily
and therefore its setting is crucial to a rich and balanced sound in all three Modes. In fact, the TREBLE feeds the
signal to the MID and BASS controls and acts like a valve for their signal strength.
HI-LO
When the TREBLE is set in its higher regions (2:00 – 5:00) it is sending a smaller signal to the MID and BASS con-
trols and they will be less active and the dominant character will be one of very bright, TREBLE-heavy frequencies.
Conversely, a very low setting on the TREBLE will produce sounds that are perhaps a little BASS heavy and overly
TREBLE MIDDLE
dark as a very large amount of signal is shoveled toward the MID and BASS controls. So you can see that setting
the TREBLE with taste in mind and care is critical for the Tone control string to work in harmony.
In both Channels and their Modes the middle region of the TREBLE delivers the best balance and creates sounds that are plenty
bright enough but still rich and warm. We suggest that you start with the TREBLE at 12:00 and adjust up or down slightly until the
desired blend is achieved.
In the HI/LO Channel, the MID control carries frequencies that are somewhat close to the TREBLE, along with the upper mid and
lower mid frequencies it is centered around. Use this idiosyncrasy of Brit style architecture to your advantage and experiment with
setting the TREBLE lower than "normal" and running the MID up a bit and vice versa. Some very cool sounds can be found with
the TREBLE lower and the MID higher. Be sure to check this interaction between these two powerful controls, as it will be critical in
achieving the sounds you hear in your head.
