5. Normally this is setup on the mixing console When setting up a traditional parallel compression you route the direct and uncompressed signal to a stereo bus bus A simultaneously you route the signal to a Stereo bus with a stereo compressor inserted then you route the processed signal to bus A also Seems pretty simple but there are definitely downsides to that method If you make any level changes on the compressed or the direct signal it will affect your stereo mix due to the lack of level compensation in the two signals Also you cannot mix digital and analog devices in the chain unless time align all signals correctly So there are several pitfalls that invites to mistakes especially in stressed situations DON T WORRY The C400XL New Style Compression will assist you in setting up parallel compressions fast and easy A unique feature that so far is unseen in a compact unit The main object is mixing the unprocessed signal with the compressed signal Mixing is easily done using the MIX knob Setting MIX to 100 lets the C400XL operate as a regular compression Setting MIX in any position between bypass and 100 applies new style compression Why What does it do to the sound The higher dynamics are better preserved and at the same time the details from the lower dynamic parts of the signal vie E Try to apply parallel compression on a drum kit You will discover that all the lower

27. ut with a Gate expander it is also possible to reduce the noise on channels when no significant signal is present Basics A Gate or downward expander is used to attenuate the signal when the signal is below a certain threshold When talking about attack and release times in reference to a noise gate the attack time is the time is takes to for the gate to open when the signal rises above the threshold and the release time is the time it takes for the gate to reach the specified attenuation No expansion Output Level dB Pur 1 1 2 expansion 1 4 expansion Input Level dB C400XL Gate presets All presets except for Hiss Hum trigger dedicated Gate Expander settings tuned to the various preset materials Hiss amp Hum presets Dedicated presets for hiss and hum elimination C400XL PROCESSING C400XL New style compression an innovative approach to compression Do you recognize the situation where you read about a technology maybe even in details and feel that you really understand the concept Then once you are in a stressed environment and try to apply you new found wisdom you loose the overview and though it looked really good on paper you now don t seem to pull its full potential Parallel compression could actually be one those understandable when read technologies that you tend to mess up in a real life situation With the C400XL New Style Compression NSC yo
