TK Audio DP3
MPN #DP3
Hybrid vintage-modern preamp, Germanium mid crunch, class-A punch, 80s-90s tone, Lundahl input, Carnhill output, sweepable HPF, Hi-Z direct mode
The DP3 is a unique hybrid design including both vintage and modern circuits. The midrange crunch of the germanium sound of the mid 60's, the low mid punch and thick sound associated with British class-A from the early 70's as well as the more modern tone from the 80's and 90's.
It contains not just our well proven input stage and germanium circuit, we have also incorporated a new saturation circuit that together with the vintage class-A stage gives you lots of character choices.
The input stage is designed around a high quality Swedish Lundahl transformer and a hi-gain stage followed by selectable saturation and germanium circuits for more color and harmonics.
Instead of switching output stages as it was done in our previous models the class-A stage is now inserted in front of the output level control letting you drive the transformer harder without overloading your A/D converters. This also make the output less sensitive to different load impedance. The class-A stage uses a heavy custom made Carnhill transformer that produces a fat and punchy sound with mid-range character and a warm top end.
The Hi-Z instrument input has a separate activating switch so that you can let your instrument stay connected all the time. The Hi-Z direct mode function bypass the input transformer and input stage and send the instrument signal direct to the HPF and the selectable saturation and germanium circuits.
Direct mode gain is +14dB which is perfect for bass recording together with the class-A stage.
The sweepable HPF goes from 30Hz to 400Hz which allows precision crafting of the low end.

It is connected before the output level control to show the internal headroom even if you have lowered the output level.
