Description
The dbx 286s is a channel strip with a microphone/instrument preamp and four processors: a compressor, a de-esser, an enhancer and an expander/gate. The processors work on their own or in any combination, so one track gets the whole processing chain in one box with a short signal path.
The preamp has wide-ranging gain, switchable +48 V phantom power and an 80 Hz high-pass filter for hum, rumble and wind. The OverEasy compressor smooths uneven acoustic tracks or gives vocals an upfront sound, and the frequency-tunable de-esser tames sibilance and harsh cymbals. The enhancer's HF Detail and LF Detail controls add crispness on top and fullness down low while clearing muddy low mids. The expander/gate has separate threshold and ratio controls, from light cleanup of headphone leakage to hard gating of a noisy guitar amp. An insert jack between the preamp and the processors connects an outboard EQ or delay.
