dbx 92
Not much is documented about the dbx 92. It shows up in the period record as an audio signal processor, but the only substantial coverage that survives is an equipment profile in Audio (November 1986, p.84), which reproduces the manufacturer's specifications. Most of the other period clippings gathered under this model's name are about different dbx products - the 160X compressor, the Soundfield Ten speaker system, the 172. The 92 itself seems to have drawn little standalone attention.
The specs in Audio's profile describe a clean, flexible processor. Frequency response is 10 Hz to 20 kHz (+0.5, −1.0 dB). THD is below 0.002% at 1 kHz with the signal-processing circuits switched out, and 0.07% with them engaged. Dynamic range is 96 dB without processing and 60-106 dB with processing. The stress on dynamic range and switchable processing points toward dbx's familiar noise reduction or expansion territory, but the surviving excerpt never states the unit's intended use. No production years, original price, or design details have surfaced.
