Empirical Labs EL8-X Distressor (Brit Mod)
Mono FET Compressor with British Mode & Stereo Image Link
The concept of British Mode came from an unusual setting on the classic UREI LN1176 limiter. The unit was designed to have only four ratios, each ratio being engaged by selecting one of four buttons. However, as early as 1980 (or before), renegade recording engineers, always on the lookout for something a little more 'over-the-top', found that you could make all four buttons stay in if you pressed them just right. What resulted was a very aggressive sound that had some elements of the unit's 20:1 ratio, but with an unusual knee and new envelope shape. Somewhere along the line, someone called it 'British Mode', and the name stuck.
The EL8-X has the advantage of being able to selectively apply this aggressive characteristic - not just to the new 'British' ratio (1:1) - to any of the ratios, simply by engaging the dedicated 'British Mode' switch.
Digitally Controlled Analogue Knee Compression
The Distressor is the product that started it all for Empirical Labs. Born of founder Dave Derr's love of classic compressors like the 1176, LA-2A and Gain Brain (among others), the Distressor incorporates his favourite sonic characteristics of these, along with other unique and interesting features that have made it a staple for audio engineers all over the world. With over 22,000 units in the field, it's safe to say that the Distressor is one of the best selling high end compressors of all time...if not THE best selling. A prominent recording engineer recently wagered that there probably was not a top 40 record made in the last five years that didn't have at least one Distressor on it.
Besides providing a wide range of control and a unique feature set, the Distressor offers a warm, vintage sound by using a custom designed gain control circuit. This "warmth" or "vintage sound" has become a major issue in the last few decades, as the super clear and linear digital technology does next to nothing to soften 'harsh' sounds, nor emphasise the bass frequencies in music sources. Conversely, older analog tape, vinyl records and tube equipment could not be prevented from colouring the sound, often to the frustration of recording engineers. However, many people now realise that this colouring can be extremely pleasant and musical. Digital technology is often referred to as 'cold' and 'brittle' among other terms.
All eight of the Distressor's curves are unique and distinctive, from the 1:1 mode that simply warms up signal with low order harmonics without intentional compression, to the 'Nuke' setting - a brick wall limiting curve that shines on live drum room mics. Each curve has its own personality and several actually use different circuitry, and are effectively different compressors. Most exceptional is the 10:1 'Opto' ratio which uses separate detector circuitry to emulate the oldest (and valued) 'light controlled' devices, such as the LA-2A.
Another large part of the Distressor's personality and power derive from three modes that colour the signal, even without compression. These extended audio modes were designed to allow emulation of some very old and expensive vintage compressors & limiters, and let the Distressor deliver a classic 'knee' sound all its own by providing user programmable, warm harmonic distortion. In addition to the basic distortion mode, Distort 2 emphasises tube-like 2nd order harmonics, while in Distort 3 setting the distortion becomes dominated by 3rd harmonics more closely resembling tape. Two HP filters - one in the audio path, one in the detector path - are also available to help with low frequencies that can cause pumping and breathing.
