Before You Start - Mesa/Boogie Royal Atlantic RA-100 Owner's Manual

HELPFUL HINTS:
1. Cut the cable tie that holds the AC Power Cord to the Rear Tube Cover and connect it to a Grounded AC wall socket.
2. Connect the Stereo ¼" Footswitch Cable to the Front Panel ¼" jack labeled FOOTSWITCH using the supplied Stereo Cable.
3. Set the amplifier (and at least one speaker cabinet) on the floor you will be standing (or sitting on) while playing to complete the
coupling circle that occurs. This will make the amplifier sound better, as well as feel better to play, because the sympathetic loop
created by the transmission from your hands to the guitar to the amp to your guitar to your hands remains unbroken.
4. Using the Multi-Soak™ Power Attenuators at the maximum (last two) attenuation settings with the Channel MASTER volume
controls set high (to achieve highest blend of power tube clipping) will wear your power tubes down at an accelerated rate. If you
do use the Multi-Soak feature extensively as part of your everyday sound palette, don't be surprised if you start noticing power
tube wear and compromised (dull, flat and lifeless) tone within a couple months or even sooner.
5. Use the 50 Watt POWER setting on the Front Panel POWER switch to achieve clipped sounds at the top end of the VOLUME
control in the CLEAN Mode.
6. The TREBLE control is effective at adding additional gain to clipped sounds in CLEAN with the VOLUME cranked (5:30). Try
setting the TREBLE higher (2:00 – 3:00) and reduce the MID to achieve more warmth.
7. There is substantial top end carried in the MID control along with the midrange frequencies it adjusts. Some like to run the MID
higher and then reduce top end at the TREBLE control.
8. Our suggestion in the HI Mode is to use the Soak with tone in mind and follow this obvious and simple scheme; If you
want to add power section overdrive to an already gained-out sound with the Multi-Watt Soak – Reduce the setting of
the GAIN control accordingly. In this way you stand a better chance of arriving at a sound that is a beautiful blend of preamp
saturation and power amp overdrive.
IMPORTANT: Using the Multi-Soak Attenuators frequently will cause increased power tube wear and shorten their Toneful life. This
wear is more rapid if the attenuation is extreme – as it is in the two most attenuated positions (-12db and -16db) of the rotary control. If
you use the Multi-Soak as an integral part of your daily Tone palette, you can expect a relatively short life-span (2-4 months) from your
power tubes. In comparison, someone using the Multi-Soaks as a strategically applied effect for recording or small venue inspiration
would likely get 6 months to a year or even more from a set of tubes before they noticed any degradation in the sound.
Now that you have an overview of the features of your Royal Atlantic, let's get specific with the modes and controls to help you
better understand how to get the sounds you are looking for and apply them to your music.
