1176LN Rev E

The Rev E represents the early-1970s low-noise Blackface branch of the 1176 design. Relative to the early Bluestripe, the manual identifies a more linear compression response, transistor gain amplification, and different program dependence. This is the modern circuit-modeled Rev E, not the lighter first-generation 1176LN Legacy.

The architecture couples compression drive to Input, then provides Output for level matching. Attack operates on an unusually fast microsecond scale, while the release depends on both the knob and the preceding signal. That combination suits individual vocals, drums, guitars, or a drum bus, from controlled peaks to conspicuous envelope changes.

Establish the compression with a single ratio before exploring the multi-button modes. Use timing to balance impact against density, and compare at matched output level. Input and output amplifiers remain part of the sound even without reduction, making ratio-off or Attack OFF useful for tone-only processing. Headroom, Mix, and a sidechain tilt filter provide workflow options that the LN/SE Legacy versions do not include.

• Input: Turn clockwise to increase the level driving compression and the associated distortion. The panel scale is not a calibrated dB scale, and minimum Input is not guaranteed silence. Judge the setting using reduction, source envelope, and tone together.
• Output: Adjust the outgoing level after setting the desired reduction. It does not control the compression amount, although greater output drive can add modeled amplifier distortion.
• Attack: Approximately 20–800 microseconds, with the fastest response fully clockwise. A slower setting allows more of the attack to escape; even that end of the normal range is very fast. Click OFF to bypass the compression circuit while retaining the modeled I/O path. Do not confuse this with full bypass.
• Release: Approximately 50–1100 ms, faster clockwise. The Blackface's program-dependent recovery differs from the Rev A and AE, so identical positions need not breathe the same way. Tune by listening to the space after each hit or phrase.
• Ratio: Select 4:1, 8:1, 12:1, or 20:1. Higher values generally suit limiting. Shift-click enables the supported multi-button combinations; All Button changes timing and the compression curve as well as distortion. With all ratios disengaged, the model processes tone without gain reduction.
• Headroom / HR: Select 4–28 dB in 4 dB steps; 16 dB is the default. A lower displayed number means more headroom and less readily driven coloration. A higher number pushes the model harder at the same incoming level. Avoid automating HR because changes can briefly increase gain.
• Mix: Set the dry/wet balance continuously. Use full wet while designing the compression, then reduce it to retain some original transient and dynamic movement.
• Sidechain Filter: Toggle the symbol or Release label for a fixed 10 dB/decade tilt. This makes low frequencies less dominant in detection without directly removing bass from the signal.
• Meter Function: GR displays reduction; +4 and +8 display output. OFF disables processing. All-button and other multi-button settings can produce deliberately unusual GR meter behavior.
