Welcome

Thank you for purchasing a Dynamic guitar amplifier from DMT, Inc. Our carefully
hand crafted amplifiers are the product of decades of experience as designers and
players. Every player that has been on the quest to find their sound knows that this
pursuit as it evolves is frequently frustrating, which makes finding the right tools to
get there to be immensely rewarding….and at times inspiring. We sincerely hope
you to have found these with DYNAMIC.

To get there, good design has to be followed by careful attention to quality parts,
thoughtful layout and useful features. Combining these elements we have created
for you a versatile creativity-enhancing extension of your instrument, that will prove
reliable for many years of “hard miles”.

As some of the features we have included are unique and therefore not typically
found in other amplifiers, please take time to read this short manual so you can
wring the most “juice” from the 2040.

In choosing Dynamic, you join the ranks of a small but growing group of discerning
musicians who choose to go beyond the mundane in search of extraordinary sound.
We invite you to read about the amp, then plug in and enjoy getting to know the
amplifier.

FRONT PANEL CONTROLS

INPUT: High impedance guitar input.

BRIGH T: Accentuates top frequencies. Particularly useful with hum-bucking

pickups. (Three levels)

VOLUME: Preamp gain control. Start at 10 o’clock, with the Master set at 12:00
o’clock for starters.

GRIND: Gain booster. This switch increases gain by 6db approximately, makes
getting a saturated sound easier to achieve. Especially useful when using single-coil
guitars, or when playing at low volumes, where more preamp grind is desirable.

CLEAN: Preamplifier gain control. This is a three-way switch. This controls the
level of signal hitting the power amp at the Phase Inverter (PI). The switch set to the
Left produces no reduction, the middle is moderate reduction and the right position
is the most reduction. The amplifier will be cleaner sounding in the middle or right
position, however, the overall volume is also reduced, so Master volume
compensation might be needed. Experiment with different levels of Gain, Clean and
Master, and see the subtle and not-so-subtle changes in tone that occur.

VOICING: This five position rotary switch controls the tone modification options.
Left to right: (each mid-dip affects a different center frequency)

Position 1- Mid-frequencies dip (tone control enabled)
Position 2- Mid-frequencies dip (tone control enabled)
Position 3- Mid-frequencies dip (tone control enabled)
Position 4-Tone control only, enables brightening hum-bucking pickups.
Position 5- Tone stack bypass. Fattest sound, highest gain (great for single coil)

TONE: This knob functions as a full-bandwidth tone control, where the full left
rotation has the low-end rolled off, (thin), and as the knob is rotated clockwise, the
low-end tilts up (fattens) until it is rotated to about 90% at which point the top-end
rolls off when fully rotated to the right.

TREMOLO: FREQUENCY & INTENSITY: This popular retro-feature is presented
here with the typical frequency and intensity controls, what is unusual, is the degree
of intensity it will adjust to, and the extreme range from slow to fast frequency that
can be selected. This effect is foot-switchable from a jack in the back panel.

REVERB Mix & Hi / Lo: The Hi / Lo switch determines the intensity of the reverb
drive (input) & the Mix knob controls the amount of reverb-processed signal blended
with the original signal. Hi might recall vintage “surf” reverb, and Lo is more of a
ambience enhancer, less intense. The Reverb effect can be controlled (on or off) by
a footswitch plugged into the REVERB jack in the back panel.

MASTER: This post PI master volume is an excellent way of controlling volume
while preserving most of the desirable qualities of overdrive at lower volumes. Truly,
the best characteristics of a good tube amplifier are usually heard with the Master
set from 2 to 4 o’clock. But in real life, amps need at times to be turned down. More
on that later. See PowerStep, on rear panel.

STANDBY: When the switch is down, Standby mode is ON. Every time the amplifier
is turned on, this switch should be down or “on” for 15 seconds or more to let the
tubes warm up.

INDICATOR LAMP / POWER SWITCH: When the power switch is turned on, the
indicator lamp will glow, which indicates there is AC power, and the amplifier is
beginning to warm up.

NOTE: ALL TOGGLE SWITCHES ORIENTED HORIZONTALLY ARE ON WHEN
THROWN TO THE RIGHT. THE VERTICAL HI/LO SWITCH IS THE EXCEPTION
BECAUSE IT IS EITHER HI OR LO, NOT ON OR OFF.
