Trilogy™ Manual 1.1
Foreword
Even in the new millennium, classic rock, blues and metal
sounds of last century's great guitarists continue to shape
musicians and audiences' tastes in tone. Back in the day,
flexibility wasn't top on the list of amp attributes: Two channels
were standard, three a luxury, and four MIDI switchable channels
a dream at best. And now monster nu metal sounds, detuned
guitars, blistering bare-knuckle riffs and clean yet heavily effected
sounds have gained currency in the repertoires of countless
rock bands. Yesteryear's tube amps are no match for today's
sonic diversity challenge.
Enter Trilogy™. You have chosen a tube amp offering a rich
feature set. Its mighty arsenal of sound-sculpting features
that makes the dream of total mastery over tone come true.
It boasts four independent channels tweaked to deliver
markedly different slices of the tonal pie, a further variation
on the fundamental sound in the CLEAN and CRUNCH channels
each, and a whopping 128 effect combinations that can be
stored via MIDI in combination with these six sounds. In a
nutshell, you get plenty of sonic firepower to make every
gig pure playing pleasure.
Things to do before operating
the Amp
A word of warning before you fire up your new amp: It's loud!
High volume levels can cause hearing damage. Always twist
the MASTER VOLUME knob to the far left-hand position before
turning on the amp, and then slowly rotate the knob clockwise
until you dial in a level that is comfortable for your ears and
suitable for the venue. Keep those levels well under the pain
threshold!
Check the voltage rating displayed next to Trilogy™'s MAINS
INPUT to make sure it matches your local mains current before
you plug the amp in. Ensure plenty of air can circulate around
your amp's ventilation ducts. Place the amp on a sturdy, secure
base and avoid exposing it to mechanical shocks and extreme
temperatures that could endanger the device or your and
others' safety.
The manufacturer disclaims any liability or responsibility what-
soever for any damage or defect to this and other devices
resulting from misuse.
Powering up
First plug the speaker cord into appropriate Speaker Out on
the head's rear panel. Your choices are a 4-ohm output, a pair
of 16-ohm outputs, an 8-ohm output and a 16-ohm output.
More on this in chapter 2 – Rear Panel Connections and Control
Features. Plug the other end of the cord into the speaker cabinet's
input. This amp-to-speaker connection and impedance matching
are vital to every all-tube amp's life! Tube amps operated
without the load of a connected speaker or at an insufficient
impedance level die!
Plug the head's mains cord into a wall outlet and power the
amp up by engaging the MAINS switch. Allow the tubes to
warm up before you begin playing. First plug one end of the
guitar cord into the guitar, and then the other end into the
amp. Flip the STANDBY switch to bring those glowing tubes
to life.
