Our mic pre is the most important part of your signal chain. Each QPP features four all-discrete, all-iron mic pres with a simple and powerful amplifier. We offer a variety of input transformers, output transformers, op amps and even voltages to give you the sound you need. Whether you're looking for quiet and clear, warm and smooth, or edgy and rock and roll, this preamp can do what you need.
The input transformer can feeds a discrete operational amplifier for up to 64 dB of gain, followed by a custom-wound Cinemag Output transformer with a infinitely variable T-pad attenuator. A dB pad, phase, mute, and 48V phantom power round out the preamp.
