Compressor 276 (mono), Compressor 276S (stereo)
These models recreate the fast response, frequency characteristics, and tube-amp saturation of the most in-demand analog compressors for studio use, delivering classic-style compression with all the punch and fatness you'd expect from a fine piece of studio-grade analog gear. Not limited to processing drums and bass, these compressors are also an excellent choice for vocals and master stereo mix compression. The 276 is a dual mono unit, while the 276S operates in stereo

Compressor 260 (mono), Compressor 260S (stereo)
Featuring faithful modeling of the solid-state voltage-controlled amplifier and RMS detection circuitry of the late 70's, these Add-on Effects bring back the sound of classic comp/limiters used primarily for live sound reinforcement applications. They offer three selectable compression knee types — hard, medium, and soft — and although variable attack and release are provided, presets recreate the fixed settings of the vintage gear. Top-level sound-reinforcement engineers have carefully tweaked the parameters for optimum response in live situations. The 260 is a dual mono unit, while the 260S operates in stereo

Equalizer 601
The 601 equalizer offers two equalizer types - Clean and Drive. The Drive type models the distortion characteristics of 70's analog EQ circuitry, delivering musical-sounding drive and saturation. The 601 is a stereo six-band parametric equalizer with LO and HI shelving filters and four MID peaking filters, and it accurately reproduces both the boost and cut frequency response and band interaction of vintage analog gear. And you get EQ capability over a wide 16 Hz - 40 kHz range when operating at 88.2/96 kHz. The 601 features a familiar knob-style interface as well as graphical editing capability on both the console and PC displays
