The Forssell Technologies Inc SMP-2 is a 2 channel, transformerless, Class A discrete JFET microphone preamplifier housed in a single rack space chassis. Each channel on the SMP-2 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 -5dBu, and red when the signal level reaches +22dBu, which is 2-3dB prior to clipping. A power on/off switch and LED are also located on the front panel. The rear panel contains the two input and one output XLR connectors per channel. All XLR connectors are wired Pin 2 hot. There is an input XLR for phantom powered mics (labeled P48), and one for non-phantom powered mics (DC) such as ribbon, dynamic, or externally powered condenser mics. This microphone preamplifier is housed in a 1U rack mount chassis. It is a two channel mic preamp with individual controls for each channel. Front panel controls include; Mute switch (mutes output), polarity reverse switch (relay), phantom power, 24 position rotary gain switch, and dual color LED signal level indicator (green at -5 dBu, Red at +22 dBu). There are two inputs per channel. One has +48 volt phantom power supplied to it (when phantom power is switched on) and its signal passes through very high quality capacitors to block the phantom power DC voltage from the input stage of the preamplifier. The other input is connected directly to the input of the preamplifier, bypassing the phantom power blocking capacitors. You can use this "direct coupled" input when you are using microphone that do not require phantom power, such as vacuum tube mics, ribbon mics, and dynamic mics. You can only use of these inputs at a time. Do not connect the unused input to anything cable of microphone. The connector in the middle is the Direct Input. Input and Output connectors are XLR-3 wired pin 2 hot.

The front panel mounted bicolor LED will light green when an output signal level of -5 dBu or greater is present, and this LED will turn red when the output signal level reaches +22 dBu. This is approximately 2-3 dB before output clipping on the 2 channel preamp.

Class A discrete JFET front-end coupled to three discrete JFET opamps. No IC opamps are used in the direct signal path, but an IC opamp is used as a servo amp (DC offset control) on output. The signal path is entirely DC coupled except for the phantom powered inputs. +48 VDC full current phantom power supply.

+/- 22 VDC power supply rails. Please contact me within 24 hours of receiving the item if there are any problems with it or the package. _gsrx_vers_1326 GS 8.4.1 (1326). This item is in the category "Musical Instruments & Gear\Pro Audio Equipment\Preamps & Channel Strips".
