CPU hit is prohibitive, we have added a model that is significantly less CPU intensive but slightly less accurate than the circuit simulation. Use SGA1566 preamp to add warmth to a track, as a saturation compressor, or to add “dirt” with tube overdrive.
SGA1566 Circuit SGA1566 uses a two stage triode preamplifier and a 2-band active Baxandall EQ for tonal manipulation. Equalizer The circuit schematic of the 2-band active Baxandall EQ is shown in Figure 3.
50 µ Figure 4. Schematic of the preamplifier circuit. The preamp in SGA1566 is a two stage triode based amplifier. Each amplification stage is a 12AX7 based common cathode amplifier. Common cathode configuration is commonly used in (pre)amplifiers to amplify a weak signal to levels needed to drive a power amplifier.
Using SGA1566 At low input signal levels and low Gain settings SGA1566 preamplifier simulates a clean tube preamp. When operated in such conditions SGA1566 can be used to enrich the original sound by adding “warmth”...
OS X 10.7 or higher. Windows XP/7/8. Controls Settings controlled by knobs can be changed by clicking on them and dragging the mouse up and down. Settings controlled by switches can be changed by clicking on the appropriate switch or by clicking a switch and dragging the mouse.
Stereo Stereo control lets you switch between mono and stereo processing. To set processing to mono, set the STEREO switch to OFF. Stereo processing nearly doubles the CPU load of the plug-in when compared to mono processing since in the stereo mode the plug-in needs to process two channels compared to one channel in the mono mode.
