Integra DS939 (circa 1996–1998)
The period record on the DS939 is thin. It survives mainly as an Onkyo advertising campaign and a 1998 buyer's-guide table, but those sources place it clearly enough. The DS939 was a THX-certified digital surround receiver sold under Onkyo's Integra line, badged the TX-DS939. Onkyo's ads in HI-Fi-Stereo-Buyers (November 1996, p.47) introduced it alongside the TX-DS838 and the separate ED-901 processor as the arrival of Dolby Digital AC-3 in a receiver. The ads promised a theater-like experience and cited George Lucas's THX parameters.
A HI-Fi-Stereo-Buyers receiver roundup (July 1998, p.56) listed the TX-DS939 Integra at $2,800. Output was rated at 100 watts across five channels, or 120 W × 2 in stereo. Digital inputs were two optical, one coaxial, and one RF. Analog hookups included four audio inputs and seven A/V inputs, all with S-video, plus a front-panel A/V input. It offered 18 surround modes, 11 of them music-oriented, along with an on-screen display and a microphone for automatic speaker calibration.
Beyond that, little is documented. No full contemporary review or service literature has surfaced in the archive.
