Compressor De Áudio E Expander Stereo Drawmer Dl 231

The DL231 is a dual channel Expander/ Compressor/Limiter combining ease of operation with flexible performance. Each channel consists of a compressor, having variable threshold, ratio, attack, release, and output gain controls; a peak limiter, which is required to prevent momentary overload when using gentle compression slopes and / or slow attack times and an expander / gate for the removal of unwanted ambient noise which would otherwise be ‘pumped up’ by the use of compression. Although each channel is completely independent, linking is easily accomplished, which prevents image shifting when treating stereo material. Particularly attractive features are the unique dual function displays using Tri-colour LED’s, which measure input signal levels, or gain reduction. Both expander and compressor release are semi-automatic, programme related and are adjustable via a single release control thus providing smooth operation and reducing setting up time. The expander section is equipped with fully automatic attack, which continuously adjusts itself to match the rising envelope of the incoming signal. This feature is of enormous benefit on vocals, because they contain ever changing transient characteristic, which makes manual adjustment difficult and time consuming, with sometimes doubtful results. Equalisation may be applied to the compressor side-chain insert points. This allows frequency conscious compression to be achieved. ‘Side chain listen’ facilities are provided to allow both side-chains to be monitored.
