From Other (Miscellanous Used/Vintage/Consign)

The Forssell Technologies Inc SMP-2A is a 2 channel, transformerless, Class A discrete JFET microphone preamplifier housed in a single space rack chassis. Each channel on the SMP-2A has front panel mounted controls for gain, output muting, polarity reverse, and phantom power on/off. The mute, polarity, and phantom power switches each have LED indicators which illuminate when the switch is pressed in to indicate that the switch is on. The gain control is variable from minimum to maximum gain in 24 stepped positions. Bicolor LED level indicators are also present for each channel. These LED indicators show green with the output signal level is above –5 dBu, and red when the signal level reaches +24 dBu, which is 2-3 dB prior to clipping.
