NITROUS the newly developed audio compressor from ~Sebatron~

Reach for the NITROUS and boost your tracks’ performance.

NITROUS is a single channel Solid State line-level FET audio compressor designed to have the flexibility to go from brick wall peak limiting to smooth round compression. Features include a variable High Pass Filter for the Side-Chain, fully variable Attack/Release and Ratio and a ‘Tight’ switch that changes the character of the compression curve to a slightly more ‘aggressive’ response. Nitrous also features a switchable external Control Voltage input for accurate stereo processing between two units….. Both electronically balanced and unbalanced inputs and outputs are provided.

Nitrous also features an accurate switchable LED VU and Gain reduction display.

Unlike many other hardware compressors out there in the market today, Nitrous does not use any VCA chips and so has its own distinctive sound and dynamic behaviour. The audio path is completely discrete and utilizes high voltage, low noise transistors in Class A mode to perform all gain and operational duties, giving a bandwidth extending out to 110kz and beyond. As the audio path is minimal and transparent, the unit can also be used as a high quality line level booster or general audio gain amp by using the toggled gain control on the left.

The external Control Voltage input and select switch allows the user to connect a pair of Nitrous or Proxima together for true accurate Stereo compressing . Either unit can become Master or Slave…. Or both ….

A special side-chain H.P.F feature allows you to roll off any Low Frequency energy from 40 hz to 440 hz so compression can be directed closer to the higher mid-band spectrum of the audio.

At the nucleus of the compression stage is a Precision Audio Rectifier circuit which converts the audio signal into a smooth D.C control voltage that is then fed to the FET attenuation network and gain reduction indicators.

The degree of time response and shaping is controlled by the Attack/Release parameters.
Also featured is a ‘Tight’ switch that activates a specifically contoured time compression curve aimed at percussive sounds that can exhibit nasty transient peaks…

Applications for NITROUS are extensive, whether tracking individual instruments and voices or when used in a line level sub group or full stereo mix.

When applied sensibly to virtually any sound source compression will provide a smoother consistent listening experience as the harsh unexpected transients are brought to a more manageable level by the transparent dynamics processing circuitry rather than your ear and mind.

When applied in a creative sense, the compression can make tracks sound more vibrant and exciting as the sounds and textures that would previously be lost in the mix because of their subtlety are now brought forward, up front and into focus.

Set to a Peak limiting configuration with fast attack and release, the Nitrous will give your tracks and mixes punch and dynamic consistency with an analogue feel that is impossible to get via software plug ins or digital simulators.

When adjusted for smooth levelling with slower attack and release and low ratio Nitrous can make tracks sound warm and fluid without any of the artefacts that sometimes plague optical designs nor the sterility and predictability of the VCA based designs. The compression is Linear and Organic with subtle overtones of the classic 1176 that influenced the circuit.
