JBL 7110
Documentation on the JBL 7110 is thin, and even the basic details are hard to pin down. The record does show a single-channel limiter/compressor sold under the JBL Professional banner. It followed the UREI LA-2A, LA-4, and 1176LN, and the unit was marketed as carrying those legacies into the next generation. The 7110 handled both peak and average gain reduction. It could ride gain automatically with split-second response, based on threshold, attack, release, and output level settings. A front-panel Automatic Preset button simplified setup.
Most of the surviving period coverage is advertising rather than independent review. DB Magazine (January 1994, p.45) described the 7110 as a single-channel limiter/compressor for both peak and average gain reduction. An EQ Magazine lab test from September 1990 (p.64) listed a claimed frequency response of 20 Hz to 20 kHz at +4 dBm unity gain, but the full test results are incomplete in the archive. Beyond that, almost nothing is documented - no confirmed production years, no original price, no dimensions, and no circuit details.

- Functions: Peak and average gain reduction
