Pioneer TVX-9500

The Pioneer TVX-9500 was a tuner component from the late 1970s, built to bring television audio into a hi-fi system. High Fidelity (May 1979, p.52) described it as a full-scale tuner that handled everything from antenna input to audio output - a different sort of solution from the $14.95 adapter some receivers offered, which simply piped a TV's earphone jack into the stereo. The TVX-9500 also had an FM section, and Audio (November 1978, p.110) put it on the bench. The first problem there was finding a suitable RF signal generator. The measurements that followed came out as:

FM quieting point: 23.3 dBf (8.0 µV/300 ohms)
FM muting threshold: 34.7 dBf (30 µV/300 ohms)
Capture ratio: 1.3 dB
AM suppression: 50 dB, matching Pioneer's claim

Pioneer's own ads of the period were blunt. A spread in High Fidelity (October 1978, p.125) argued that anyone with a TV and a hi-fi who didn't own this component was making a mistake. It dismissed ordinary television sound as closer to a cheap kitchen radio than to real audio. The pitch probably points at the intended buyer: someone who had just heard what Taxi Driver or a concert broadcast could sound like through proper speakers instead of a 19-inch set's built-in one.

Beyond the reviews and advertising, the record is thin. No catalogue sheets, service manual, or confirmed production dates have surfaced in the archive. The period press we have brackets its market presence from late 1978 into spring 1979.
