    image.jpeg To be clear, this is the ORIGINAL American-made CAD E300, not the newer Chinese made version currently available. This is a highly regarded studio mic, for both vocals and upright bass. Includes mount, case and documentation.

    "The Equitek E300 combines a vintage capsule design with advanced electronics. Typical FET (field effect transistor) condenser microphones use discrete designs. This means they use individual transistors that must be carefully matched for proper characteristics. Even with careful matching, discrete designs are inherently nonlinear. Equitek microphones use a different approach. We do not use any discrete FETs. Instead, we use advanced high speed OpAmps (Operational Amplifiers). These OpAmps are individually laser trimmed for optimum performance and have very high gain. This allows a large amount of negative feedback to be used to significantly reduce any non-linearity. During transients, these OpAmps may require more current than typical phantom power supplies can deliver. The extra current demands are accommodated by our unique power supply design. Instead of using phantom power to operate the microphone, we use it to charge a pair of rechargeable NiCad batteries. This system creates a huge current reserve for the microphone’s electronics, yet there is no maintenance involved because the microphone automatically keeps the batteries charged during use."
