MANUAL
The DP-13 model 3-channel guitar preamp is designed with five 12AX7 tubes. It has a rack design (1 unit high) and is
convenient for use both in the studio and in concert activities, easy to use. It has a wide range of sound adjustment that
allows everyone to find their own unique sound.
џall-tube sound path (5 tubes 12AX7) with the ability to use tubes from different manufacturers separately for clean and
overdrive sound;
џ3 completely independent channels: CH-1 CLEAN (clean channel), CH-2 LEAD 1 (overdrive channel) and CH-3 LEAD 2
(drive channel). Channel switching is carried out both on the front panel and from the 2-button foot controller that comes
with the preamplifier;
џFX LOOP tube effects loop with a choice of operating modes (serial or parallel), switching on / off separately for clean /
drive channels, control from a two-button foot controller, softening the sound of transistor and digital processing due to
the use of a 12AX7 lamp in the circuit;
џconnecting to the instrument input of a guitar amplifier (as an effects pedal), to the RETURN of a guitar amplifier, or to a
final power amplifier (as a preamp);
џbuilt-in speaker simulator for line connection and recording devices;
џdedicated headphone output.

R&R SOUND AMPLIFICATION DP-13 PRE-AMPLIFIER
MANUAL 1-3
CH-1 CLEAN (clean channel):
Classic CLEAN in the spirit of the 60s. Open clear sound. Therefore, the instrument determines the future timbre of the sound.
It can be both "sharp and prickly" and "thick jazz". Lightly add gain to a slight crunch, adjust the EQ to taste and get a punchy
CLEAN. With a further increase in gain, the sound begins to smoothly overload, turning into a light CRUNCH.
CH-2 LEAD-1 (overdrive channel):
The sound of this channel is in the best traditions of hard rock. Tweak the gain and you get the easily recognizable CRUNCH,
clear and rich sound. If you want a real rock drive - turn the GAIN knob all the way down and a fat overdrive will give you
expressiveness in the mix. The dynamics of this channel are hard to ignore. You can play solo, you can scratch the riffs. It is
well "warmed up" with all kinds of "heaters".
CH-3 LEAD-2 (drive channel):
A distinctive feature of this channel is that the GAIN control works from the cleanest sound to the extremely overdriven one.
Get ready real high gain lovers, you won't be able to resist! Even at the highest gain, the sound does not fall into the mix, it
continues to be readable. This channel is extremely versatile. It can be soft and pliable, or it can growl. Set the GAIN knob to
15 o'clock and feel free to play the heaviest metal. Set the GAIN knob to 12 o'clock and you'll get classic rock sound.
