The input stage is built around a high quality Swedish Lundahl transformer and a hi-gain input stage followed by a selectable germanium circuit that adds more harmonics. Two different output stages can be selected – either an electronically balanced stage, or a discrete Carnhill transformer-balanced class-A stage. The vintage class-A mode produces a fat and punchy sound with mid-range character and a warm top end, while the electronically balanced output stage is less colored and perfect for clean amplification.
With up to 80 dB gain the DP-2 can handle quiet sound sources like ribbon microphones. High impedance inputs are positioned on the front for easy access when connecting guitar, bass or synthesizers. It’s also possible to crank up the input gain really loud and run a hot signal through the preamp to make it distort, and then use the output volume control to lower the output level. DP2 offers a unique set of flavors at a very sensible price.
The major updates from the DP1mk3 to DP2 are a sweepable HPF from 30Hz to 400Hz which allows precision crafting of the low end, and a separate switch to activate the instrument input. The power supply has also been updated to for lower noise.
