And now back to the news you've been waiting for... Multi-Soak™ Channel Assignable Power Soaks. Your ship has come in!
While almost everyone loves the raw power, headroom and bold authority of a 100 watt power section pumping away beneath the deck, most
of us have trouble finding a venue for all that muscle. For many of us (regardless of age) few and far between are the gigs of yesteryear - where
we fondly remember cranking away on a big-bore head – punishing both the engineers and patrons of our favorite haunts to hit that place
where we could ride the wave of high volume "inspiration" and go off. These days if you need to rely on that - most likely you will find yourself
unemployed, or at least strongly reprimanded. And while you can use the Front Panel 100/50 watt Half Power switch to berth two of the 4 power
tubes for some cool applications, it's not the ultimate solution.
Introducing Multi-Soak™. At last you can have whatever amount of power amp drive you need to deliver your personal form of magic – in every
Mode - at any volume level you desire. Let's say that again; now your Tone doesn't have to be directly tied to your volume. And one last time;
you can dial-in the perfect amount of power-clip for every footswitchable sound in your amp.
Okay, yeah this intro might be a little over the top... but damn! How long have we all struggled with that? And though Power Soaks of many
persuasions are nothing new... ones that don't rob your Tone are much harder to find. And definitely - the ability to have a Soak that gives you
a separate one for each sound and individual control over their different volumes in one built-in package... well you've just sailed off the edge
of the map... and into a New World of Power Expression.
On the Rear Panel, Multi-Soak™ appears as a row of 3 rotary controls – each assigned to one of the footswitchable Modes – that give you a
choice of Bypass (no power reduction) and four popular levels of power soak volume attenuation. A master Bypass/Engage Soaks switch resides
on the Front Panel allowing you to remove the Multi-Soak Attenuators from the signal path completely should you decide to unleash the full fury
of the beast. Whether you end up relying on the Multi-Soak feature for all your sounds or you only use it for specific Modes and applications, the
versatility it creates is extremely powerful in both recording and live environments and makes the RA-100 unique in the world of big-displacement
heads. NOTE: ! High Master Volume settings (on any tube amplifier) will cause the power tubes to wear at an accelerated rate. Like
the tires on a car driven at the limit much of the time, continual excessive use of the Multi-Soak Attenuators to reduce a MASTER setting that
is too high to use without the Soak engaged will cause decreased tube life. This will not cause damage to the amplifier, but it will increase your
maintenance costs. NOTE: ! We recommend using the HIGH FAN setting when using Multi-Soak to attenuate the power.
The Royal's got Reverb. Lush all-tube Reverb drenches the RA-100's three Modes with a beautiful 3-D halo and provides you with assignable
choices on where to use it for the best footswitchable results. A 3-position Reverb MODE DEFEAT mini toggle in the REVERB section of the
Rear Panel lets you have the Reverb active in all Modes "ON" (toggle center), Defeated in HI (on in CLEAN and LO) or Defeated in HI and
LO. (on in CLEAN only). The RA-100 also provides a master REVERB BYPASS switch that enables you to remove the REVERB and all as-
sociated tubes and circuitry from the signal path for a more true-to-(at least Brit)vintage response. And if you still need more control than this
sophisticated approach to applying REVERB offers... we've provided a "hidden Reverb kill" jack on the tube side of the chassis giving those
who "don't mind the dance" total control.
An old favorite, we've included our handy BIAS SWITCH that allows you to swap the stock compliment of EL34 with the fatter, rounder sounding
6L6... for those who want to lean heavily on American citizenship when it comes to crunch time (and even more so in CLEAN). NOTE:! Make
Sure Bias Switch Setting Matches The Tubes In Use !
Keeping a cool head is always a good idea, but for those times when passion gets the better of you (or you just have to play real quiet) we've
fitted the Royal with a 2-speed fan switch. We recommend keeping it set to HIGH for the longest tube life and trouble-free operation, but the
LOW (quieter) setting is there for recording sessions (and late-night serenades on the deck). NOTE: ! The Multi-Soak™ Attenuation Fea-
ture Generates Additional Heat. This heat increases as the amplifiers MASTER Volume Controls are increased while the Multi-Soak
Attenuator's are dialed to reduce volume output to the Speaker. We highly recommend using the FAN on the HIGH setting anytime
the Multi-Soak Attenuators are used to reduce an otherwise extreme output signal.
