The Waves SSL 4000 Collection was developed under license from Solid State Logic. Includes 3 meticulously modeled plug-ins based on the legendary SSL 4000 Series: the SSL E-Channel, the SSL G-Master Buss Compressor, and the SSL G-Equalizer. This set of TDM format plug-ins sounds so close to the original consoles, even experts who work with SSL boards day in and day out can't tell the difference. SSL G-Master Buss Compressor Based on the renowned master buss center compressor of the SL 4000 G console, the Waves SSL G-Master Buss Compressor captures the unique sound of the original's IC input and twin VCA gain-reduction amplifier design. SSL E-Channel The SSL E-Channel delivers the incomparable sound of the Solid State Logic 4000-series console's all-discrete design and its Class A, VCA chip. It's a slice of the world's greatest hit-making machine, in your computer. The equalization section of the SSL E-Channel is based on the renowned Black Knob equalizer, developed in 1983 with legendary producer George Martin. It features a High Pass Filter, Low Pass Filter, and a 4-band parametric equalizer. The dynamics section features a soft-knee compressor/limiter and an expander/gate modeled on the SSL LS611E. Like the original, it can be placed before or after the equalization section, and makeup gain is automatically applied to maintain a steady output level. SSL G-Equalizer This 4-band equalizer, modeled on the SSL G Series EQ292, offers greater gain change than the E-Series EQ, and a slightly different curve. The SSL G-Equalizer includes a preboost dip and a precut rise, as well as a broader Q for more extreme equalization. That's why many leading engineers use the E Channel's equalization for detailed problem-solving and mixing, and the SSL G-Equalizer to shape and give character to the sound.
