audio path quality

So what makes it sound so good? The audio input feeds directly into the BE41 Class A discrete amplifiers via high end Wima coupling capacitors for the ultimate in clarity and low noise. High current line drivers then excite the Lundahl LL1517 output transformer, which adds a subtle warmth to the sound. The topology is quite different to other mic preamps in that it is balanced throughout. This helps provide the very high headroom specification for an effortless sound and punch. The high impedance inputs feature our BE43 bootstrapped FET amplifiers, perfectly matching your pickups and synths into this gutsy signal path.

microphone friendly

If you use dynamic and/or ribbon microphones you know they sometimes need a lot of gain, which many low cost preamps and audio interfaces cannot provide. The QSP-20 4 channel preamp provides up to 70dB of effortless gain for all situations, and the transformer-less input matches all microphone types nicely. Think of the QSP as merely an extension of your microphone - everything sounds real.

specs that matter

Having lots of gain is one thing, but importantly the preamp must also be quiet and the QSP does not disappoint here thanks to our perfected amplifier design. The very wide frequency response (even at high gain) ensures transients and high frequency content are preserved which make the QSP an excellent choice for percussion and acoustic insturments. But it never sounds brittle or sterile - the Lundahl output transformer see's to that! The very high output headroom of +29dBu out performs most low cost preamps and audio interfaces.
