JBL 6215 (1986)
Little is documented about the JBL 6215 beyond a brief listing in period professional audio directories. It was a two-channel power amplifier rated at 35 watts into 8 ohms, 45 watts into 4 ohms, or 90 watts in mono bridged mode. That is a modest output for a pro amp, aimed at installations with minimal power requirements, such as driving small monitor or distributed speaker systems. Studio Sound (August 1986, p.30) noted the 6215 was built to fit a single 19-inch rack space and used a low overall negative feedback design with local feedback in the driver stage.
Surviving specs indicate the front panel carried a headphone jack. The rear had a mono/stereo bridge switch and 5-way output binding posts. Inputs were standard 1/4-inch TRS, XLR, or barrier strip. It measured 1.75 x 19 x 10 inches and weighed 18 lbs. DB-Magazine (March 1986, p.35) listed the price at $576.00.
Production years, original pricing beyond the single 1986 listing, and any owner or service history are not documented. It appears to have been a short-lived entry in JBL Professional's mid-1980s amplifier lineup, flanked by the more powerful 6230 and 6260 models.
