Studio quality Mic Preamp/Channel Strip Processor
The 286s Mic Preamp delivers up to 60dB of sonically transparent gain to reveal the detail and audio signature of even the most esoteric mics. It transforms their low level output signal to a high level, high current signal that is internally fed to the 286s main processing chain (i.e., compressor, de-esser, etc.)
Classic dbx Compression puts great sound within easy reach
The Compressor section of the 286s changes its gain in response to the signal at its input. Many compressors have a user-selectable level, called THRESHOLD, to help determine when compression occurs. If the input signal is low in level (below the threshold of compression) the compressor gain remains fixed. If the input increases above the threshold of compression, the gain begins to decrease (i.e., the amount of gain reduction increases). For very large input signals, the gain can decrease considerably. On the 286s, compression occurs as an input level is “driven” into gain reduction by the 286s's DRIVE control; as the DRIVE setting (adjusted clockwise from OFF) increases input gain, the amount of gain reduction also increases. The 286s does not have a Threshold control; the threshold is established by the setting of the DRIVE control.
Frequency tunable De-Esser reduces sibilance and high frequency distortion
The De-esser section of the 286s reduces the high frequency energy present in certain vocalizations, of which the most common is sibilance. Sibilance is the hissing or rushing sound produced by blowing air through a constricted (narrow) mouth opening or across the edge of the teeth, as in the “s” and “sh” in “sash.” Sibilants contain predominantly high frequency components with a sharp rise above 1kHz and most of the energy in the 4kHz to 10kHz band, centered on 6kHz to 8kHz.
Enhancer increases the detail and definition of the high and low frequencies
The dbx286s's Enhancer adds detail by enhancing the low and high frequency content of the signal. The Low Frequency enhancement simultaneously applies an 80Hz boost and 250Hz cut to the signal. This lets you apply substantial bass boost without making the material sound muddy or boomy due to excessive mid-bass boost. The High Frequency enhancement is a form of dynamic phase and amplitude equalization. Continuous analysis of the input signal intelligently and automatically determines the amount of equalization necessary at each moment to achieve detailed, defined audio that is never shrill or over-sibilant.
Program adaptive Expander/Gate
Utilize the 286s's Expander/Gate controls for numerous applications. Slow settings are useful for gating out noise present behind vocals and acoustic instruments. Fast settings are useful for tightening up the sound of percussion (e.g., kick or snare drum) and drying up leakage from other instruments into percussion tracks.)
Insert jack allows you to add an external processor
External audio processors (e.g., equalizer, delay unit, etc.), can be placed in the signal chain directly between the Mic Preamp Section and remaining 286s processing via the rear panel INSERT jack.
Full compliment of meters and status LEDs
Easily determine the processing status of the 286s via the front panel LEDs.
