Empirical Labs EL8-X
The Distressor's "X" variant adds a British Mode and a stereo image link switch. Two small changes, and the box behaves differently.
Overview
The EL8-X is the version of Empirical Labs' Distressor that carries two extras not found on the base unit: a "British Mod" and a stereo image link switch. The factory manual gives them separate pages, "British Mod on the 'X' Version (EL8-X)" and "Stereo Image Link Mod (EL8-X)." On this model both are switchable features. On a plain Distressor they would be after-the-fact modifications the owner has to arrange. The X ships with both behaviors built in.
The British Mod is the headline. Per the manual, engage it alongside the Nuke setting, a fast attack (1-2), a short release (0-5) and 10-20dB of compression. You get a "tube-y" saturation that distorts each low-frequency note in a way that reads much like a bass amplifier. The manual's suggested use is on bass guitar: track the instrument on two channels, one processed with that Brit setting and one clean, then blend the "amp" and "direct" sounds to taste at the console.
Stereo operation on the EL8-X is straightforward. Two short TRS 1/4" phone cables run from the Stereo Link input of one unit to the Link output of the second and back again. Then select Link on the front panel, where the red "Link" LED in the detector mode should be lit, or engage the Stereo Image Link Switch if the unit has one, which the EL8-X does. The manual notes that matching front-panel settings across the left and right units is usually best for imaging. It also points out that, unlike most linked compressors, the user can treat the two channels differently. One example: when a boomy tom is making both sides pump, the side without the low-frequency source can be put into DET HP mode to stop it from over-modulating. That frees up a faster release on the side that needs it.
For room mics, the manual goes further and suggests leaving the units unlinked entirely, since the unique left and right ambient envelopes can actually widen the stereo image. To link the pair while avoiding image shifting, the prescribed method is the dedicated Stereo Image Link Mod on page 13 of the manual.
The manual also collects a handful of practical starting points. To hit quick +4 tape levels, set the output around 8 and raise the drive input knob until compression begins. For -10 equipment, try 6.5 on the output, and for ADATs, 6 to 7. You can push distortion levels by going into Link mode with the stereo links unplugged. The unit will not work in stereo, but "Link" sums two inputs, and with one missing the distortion generator receives a hotter signal because the detector is seeing half of what it would in true stereo operation. The manual suggests this trick for bass guitar in Dist 3 mode, for extra grunge. Sidechain processing is also possible: take the Link Out of a unit through an EQ or preamp and return it to the same unit's Link In, then engage Link. The manual warns that the sidechain must not have appreciable delay or be out of phase. The link signal gets mixed back in with the normal detector signal, and delay would cause combing of the frequency response, which the manual calls irrational compression behavior. Submixing a compressed signal with a dry one, "Multing" or "Splitting," is flagged as especially useful on percussion, where a fast-release compressed snare submix brings up the ring and body.
The manual treats all of these as operating techniques rather than hidden features. Contemporary coverage of Empirical Labs gear in the trade press, such as EQ Magazine (March 2008, p.164), reflects the studio-oriented context in which these units were discussed. The available documentation does not give production years, original price, or a full spec sheet. The fact sheet behind this page carries no verified specifications, so no compression ratios, attack/release ranges, or I/O figures are quoted here. The manual's page index confirms the unit covers features and specs, first-time use, example settings, ratios and classic emulation, audio modes and distortion, and detector modes with a block diagram, but the values themselves sit outside this page's sourced material. Treat any numbers encountered elsewhere with the usual caution.
