Boulder 102

Almost nothing is consistently documented about the Boulder 102. What exists points to two completely different products sharing the same model number - and the available sources don't settle it.

Boulder Amplifiers' own product page lists the 102 as a waveform monitor / vectorscope. It was priced at $695. The page gives 1MΩ/30pF input impedance, horizontal sweep speeds from 1µs/div to 500ms/div, an external BNC trigger input, dimensions of 4.0" H × 8.5" W × 12.0" D, and a weight of 7 lbs (3.2 kg). No production years are given for this version.

Other sources, including an Audiophile Oldies listing and hifiwiki.com, describe the Boulder 102 as a 16-channel, 2-bus mixing console. It has balanced XLR inputs, +48V phantom power, 100mm faders, dual EQ (three-band per channel with sweepable mid), two aux sends per channel, and eight subgroup outputs. The mixer measures 41.5" W × 12" D × 8.5" H, weighs 65 lbs, and was priced at $6,950. One source dates its production to 1983-1985.

Boulder may have made two distinct 102 models, perhaps a test instrument and a console. Or one of these descriptions is wrong. No period reviews or other corroborating documentation have been found.
