Informazioni

The dbx 168A Studio Dynamics Processor The dbx Model 168A Studio Dynamics Processor is an integrated automatic gain control (AGC) device of the highest professional quality. The 168A has a versatile Compressor that can smoothly and unobtrusively ride gain or assertively increase punch and density. The 168A also controls excessive sibilance levels and provides high and low frequency spectral enhancement as desired. The 168A achieves its outstandingly transparent audio performance by finely-tuned control circuitry that eliminate the dynamic distortions that are present in most conventional compressors and limiters, and through use of a quiet, low-distortion dbx® VCA to ensure negligible static distortion and noise. Features □ The 168A uses dbx’s newly-developed Servo Timed Binary™ level detection scheme and hybrid feedfor-ward'teedback Compressor control circuit (patent pending) to achieve outstandingly smooth, low-distortion compression. □ Release time is adjustable to optimize processing for single tracks or mixed program material. Sound can be tight and punchy, or completely transparent. □ A deteatable “silence gate” prevents noise rush-up, holes, pumping, and breathing by inhibiting sudden gain increases once the signal level falls below a preset threshold (during pauses or low-level program material). □ Adjustable feedforward De-Esser guards against excessive sibilance, tracking input levels to ensure consistent de-essing over an input level range of greater than 20dB. □ High-Frequency Spectral Enhancement circuit is an “automatic equalizer” that adapts to the input program, continuously analyzing it to estimate the amount of equalization needed at every moment. □ Low-Frequency Spectral Enhancement is a special fourth-order Bass Equalizer that permits substantial boost around 80Hz without creating muddy-sounding mid-bass. □ Either stereo-tracking or independent two-channel operation is possible. □ Two LED meters per channel simultaneously display gain reduction and peak output levels. □ Balanced, floating inputs and outputs are EMI-suppressed; the 168A is compatible with the levels and impedances found in both professional and semi-professional applications. □ 30dB gain reduction range is achieved with industry-standard dbx VCAs. □ Hard-wire bypass switches allow the operator to preserve system continuity if the circuitry or AC power fails.
