Smart Research C2B

The characteristic sound of the Smart Research C2 arises mostly from the fast response at the onset of compression, which when delayed to occur around the mid range attack settings (after 0.3 to 3 milliseconds) results in a window through which transients can still pass. When used across a mix, or with any dynamic program, this has the effect of adding 'punch', as the sidechain 'breathes' around these transients, while still controlling overall levels. CRUSH mode has been developed as an extension of this 'musicality', adding to and accentuating the factors involved in producing the character of the unit. CRUSH may sound surprising to those interested in more gentle applications, being capable of exaggerated compression effects, but in conjunction with the fast limit settings also introduced with this unit, it allows the C2 to be used for a much wider range of applications than the C1.
     
Features
• Blend or parallel compression
• Fast attack and limit settings for protective limiting
• Crush mode gives f.e.t 'over compression' with tailored frequency response, and higher distortion, for 'huge' dynamic effects
• External sidechain inputs, (for ducking etc.)
• Power fail bypass for broadcast or live sound
• Ratios 1.5:1, 2:1, 3:1, 4:1, 10:1 and Limit
• Attack 0, 0.1, 0.3, 1, 3, 10, and 30 m/sec
• Release 0.1, 0.3, 0.6, 1.2, and 2.4 seconds

Options
• External fader level control input, (to order) (stereo mastering etc)
• Extra dual channel slave units, for multi-channel applications, (film / surround formats etc.)

Sidechain High Pass filter cables
Reduces sensitivity to low frequency compression. The C2 input is split through 150Hz -6dB/octave High Pass filter to feed the External Sidechain input. The C2 operates as normal, untill the 'External Sidechain' switches selected. (External signals can still be connected if required, with or without the filters)
