Forssell SMP-500 microphone preamplifier

A version of our well-known SMP-2 microphone preamplifier, the Forssell SMP-500 has been adapted to work with the API 500 series enclosures. This extremely high-quality, sonically neutral microphone preamplifier is designed for the most demanding applications.

SMP-500 circuitry features an all Class A discrete JFET front-end with a gain range of +8 to +64 dB in 24 switched steps.

The output of the SMP-500 is fully balanced and floating, with a maximum output level of greater than +26 dBu.

Front panel LED signal level indicators are provided to indicate 0 dBu output level (green) and output clipping (red). The clipping LED lights at +24 dBu output, which is about 2 dB before actual clipping.

Polarity invert and P48 Phantom power switches with LED status indicators are also located on the front panel.
